rc selects in which register class the value should be put. This names the default dispatcher type, as specified by VULKAN_HPP_DEFAULT_DISPATCHER. 18.27 Parameters for Precompiled Header Validity Checking; 18.28 C++ ABI parameters; 18.29 D ABI parameters; 18.30 Adding support for named address spaces; 18.31 Miscellaneous Parameters; 19 Host Configuration. :), if you don't have access to boost the second solution is probably the best you can get. By default, a little helper class DynamicLoader is used to dynamically load the vulkan library. __attribute__ . 6.34 Specifying Attributes of Variables. Vulkan allows chaining of structures through the pNext pointer. For more information, see CHANGES.HTML. Asking for help, clarification, or responding to other answers. # RT-Thread v4.1.1 released Change log since v4.1.0 released Kernel rtdef.h Add BGR888 pixel format be friendly to macro expansion add 64bit default value for stack size It's almost exactly the same speed with clang++ 3.8. }; https://github.com/RT-Thread-packages/mbedtls/blob/master/docs/user-guide.md, int lwip_socket(int domain, int type, int protocol)protocolAT, . But at least for now, that feature takes lots of compile-time resources, so currently it is recommended to enable that feature only if you're willing to pay that price. Especially the first one is hard to detect. Are you sure you want to create this branch? Vulkan-Hpp provides constructors for all CreateInfo objects which accept one parameter for each member variable. sudo apt-get install -y locales locales-all, In cmd run VCVARS developer tools The following attributes are supported on most targets. Please be sure to answer the question.Provide details and share your research! autovec: 2.07s. By default, the member m_mask of the Flags template class is private. the most basic for loop. NPTL (Native POSIX Thread Library) Programming. If your compiler happens to need some different attribute, you can set this define accordingly before including vulkan.hpp. The default behaviour will soon change to that implied by the -altivec-compat=xl option Note that adding 128 and subtracting 128 are the same thing for 8bit integers. They will allow us to get the result with a single line of code: Finally, the last code example is using exceptions and return value transformation. This way a single generated Vulkan version can accept a variety of inputs without having the combinatoric explosion which would occur when creating a function for each container type. 6.34.1 Common Variable Attributes. It gets the type of the to-be-combined value, the seed, which is the combined value up to that point, and finally the to-be-combined value. Keep in mind that Vulkan-Hpp does not support RAII style handles and that you have to cleanup your resources in the error handler! manual: 1.02s. * The receiver waits to receive each one of the sends and then both sides * NPTL (Native POSIX Thread Library) Programming. warning: Current handling of vector bool and vector pixel types in this context are deprecated. Logger that writes to text file with std::vformat, PSE Advent Calendar 2022 (Day 7): Christmas Settings. By default, the standard assert funtions from is called. Your project's .h files. Work fast with our official CLI. By default, the namespace used with vulkan.hpp is vk. The ODB system also defines two special-purpose languages: the ODB Pragma Language and ODB Query Language. compare" trick by range-shifting to the bottom of the signed range: Subtract 'a'+128, so the alphabetic characters range from -128 to -128+25 (-128+'z'-'a'). Something to be aware of is that these are only baseline methods that have been used in the industry. You can download and install vulkan-hpp using the vcpkg dependency manager: The vulkan-hpp port in vcpkg is kept up to date by Microsoft team members and community contributors. You can use your own default dispatcher by setting VULKAN_HPP_DEFAULT_DISPATCHER to an object that provides the same API. See also this question about toupper() being slow on Windows when a locale is set. The above code works only for ASCII-compatible encodings. When booking a flight when the clock is set back by one hour due to the daylight saving time, how can I know when the plane is scheduled to depart? a vulkan handle. All those samples should just compile and run.

Asking for help, clarification, or responding to other answers. There is no single German character that means "SS", which is the uppercase equivalent. Resource acquisition is initialization (RAII) is a programming idiom used in several object-oriented, statically-typed programming languages to describe a particular language behavior. loop calling glibc toupper: 6.67s (not checking the int result for potential multi-byte UTF-8, though. The faster one if you use only ASCII characters: Please note that this code run faster but only works on ASCII and is not an "abstract" solution. For other compilers, you might specify the corresponding storage by defining VULKAN_HPP_STORAGE_API on your own. A member function has been added to a handle class for each function which accepts the corresponding handle as first parameter. > cl /EHa main.cpp /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /std:c++17 /DYNAMICBASE "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" /MTd. When a vulkan function returns an error code that is not specified to be a success code, an exception is thrown unless VULKAN_HPP_NO_EXCEPTIONS is defined before including vulkan.hpp. Why did NASA need to observationally confirm whether DART successfully redirected Dimorphos? With C++20, the so-called spaceship-operator <=> is introduced. What is the difference between String and string in C#? It modifies the StructureChain such that the specified structure isn't part of the pNext-chain any more. Based on Kyle_the_hacker's -----> answer with my extras. By default, this is defined to be 1 if VK_NO_PROTOTYPES is defined, otherwise 0. We have a scalar loop for that, and also to get src aligned. Error: Range-based 'for' loops are not allowed in C++98 mode.

That is, by defining it to be a NOP, you can reduce your compilation time a little. Please the top solution could pass negative values and cause UB with that. Dockerfile docker build Dockerfile docker docker build Dockerfile docker Dockerfile If nothing happens, download Xcode and try again. For late readers: Since C++11, we could use a lambda: this should not be the accepted answer since it requires boost, or the title should be changed. By defining VULKAN_HPP_NO_SMART_HANDLE before including vulkan.hpp, the helper class UniqueHandle and all the unique handle types are not available. The ODB Pragma Language is used to communicate various properties of persistent classes to the ODB compiler by means of special #pragma directives embedded in the C++ header files. 15 char string: baseline: 1.08s. How to convert a string to lower or upper case in Ruby. Why don't courts punish time-wasting tactics? On 32-bit platforms all non-dispatchable handles are defined as uint64_t, thus preventing type-conversion checks at compile time which would catch assignments between incompatible handle types. Not the answer you're looking for? Otherwise it's formatted as hard-coded in the generator. 18.24 Defining target-specific uses of __attribute__; 18.25 Emulating TLS; 18.26 Defining coprocessor specifics for MIPS targets. (The reason being: if this is implemented as a macro it will probably use a lookup table and your argument indexes into that table. boost's to_upper() seems a lot more consistent with c++ STL functions than toupper. LLVM is a Static Single Assignment (SSA) based representation that provides type safety, low-level operations, flexibility, and the capability of representing all high-level languages cleanly. Ensure that you have CMake and git installed and accessible from a shell. For those cases there are two corresponding getter functions. In some cases, it also generates cleanup code (for example if stacked floating point registers are used as on x86). As long as you are fine with ASCII-only and you can provide a valid pointer to RW memory, there is a simple and very effective one-liner in C: This is especially good for simple strings like ASCII identifiers which you want to normalize into the same character-case. So true. For the return value transformation, there's one special class of return values which require special handling: Enumerations. This can be achieved by defining VULKAN_HPP_NAMESPACE before including Vulkan-Hpp. NOTE: To avoid running the risk of a reset during cleanup we will avoid using this feature and explore alternatives later in the article. __initcall5_start, Otherwise it inlines and strlen() gets hoisted out of the loop, and it runs dramatically faster, esp. For more information, see CHANGES.HTML. gv() is the most important function of the code generator. If that operator is supported, all the structs and classes in vulkan.hpp use the default implementation of it. If you're using a Vulkan version not yet supported by the Vulkan SDK you can find the NOTE: To avoid running the risk of a reset during cleanup we will avoid using this feature and explore alternatives later in the article. Dockerfile docker build Dockerfile docker docker build Dockerfile docker Dockerfile This struct supports unpacking the return values by using std::tie. __initcall_end, __initcall3_start, Another problem with the same example is that it does not cast the argument or verify that this is non-negative; this is especially dangerous for systems where plain char is signed. On X86-64 and AArch64 targets, this attribute changes the calling convention of a function. This way the compiler throws a compiler error if a value has been forgotten. If the join is successful, * the sender must create an Address Handle (ctx.ah). This type accepts either a reference to T or nullptr as input and thus allows optional temporary structs. { RESETREAS Linux kernel coding style. rc selects in which register class the value should be put. Thus, for strings small enough to fit in cache, we get a significant speedup for strings ~128 chars long from doing strlen first. Asking for help, clarification, or responding to other answers. It takes advantage of the "unsigned compare trick", where you can do low < a && a <= high with a single unsigned comparison by range shifting, so that any value less than low wraps to a value that's greater than high. the handle type VkInstance, there's a raii-compliant wrapper vk::raii::Instance. __attribute__((cleanup()))block One notes that this answer is for a c string rather than a std::string. Under what conditions would a cybercommunist nation form? 4. Currently, there are just a couple of such defines: There are a couple of defines you can use to control the feature set and behaviour of vulkan.hpp: At various places in vulkan.hpp an assertion statement is used. In case you want to explicitly provide the dispatcher for each and every function call (when you have multiple dispatchers for different devices, for example) and you want to make sure, that you don't accidentally miss any function call, you can define VULKAN_HPP_NO_DEFAULT_DISPATCHER before you include vulkan.hpp to remove that default argument. This is neither neccessary (as they are correctly initialized by default) nor recommended. ,,. gcc -c src/main.c -o bin/main.o # # Create the object files for the static library (without -fPIC) # gcc -c src/tq84/add.c -o bin/static/add.o gcc -c src/tq84/answer.c -o bin/static/answer.o # # object files for shared libraries need to be compiled as position independent # code (-fPIC) because they are mapped to any position in the address space.

Licensed under the Apache License, Version 2.0 (the "License"); UDFuser defined function mysql mysql sql Note, that the actual memory layout of the StructureChain is not modified by that function. Install all locales The examples I have found from googling only have to deal with chars. This won't be necessary for explicit-length strings (like C++ std::string). Customize as necessary for your use-case. How to check whether a string contains a substring in JavaScript? Learn more. (dynamic_cast takes multiple calls to strcmp). The gv(rc) function generates code to evaluate vtop (the top value of the stack) into registers. Can you elaborate? It controls aspects of the object-relational mapping such as names of tables warning: Current handling of vector bool and vector pixel types in this context are deprecated. In some cases the storage for the DispatchLoaderDynamic should be embedded in a DLL. GNU/Linux The following attributes are supported on most targets. __attribute__((cleanup)) . Dockerfile docker build Dockerfile docker docker build Dockerfile docker Dockerfile This means that Vulkan-Hpp checks the return code of each function call which returns a Vk::Result. In those cases ResultValue ::type is defined as the returned type. Baseline: a loop that checks for a terminating 0 on the fly. boost::to_upper_copy(): 198.0s. LLVM is a Static Single Assignment (SSA) based representation that provides type safety, low-level operations, flexibility, and the capability of representing all high-level languages cleanly. How could one convert a string to upper case. { A negative index will give you UB.). We do an unaligned load of the last 16B of the source, and store it into the dest buffer overlapping the last 16B store from the loop. The sender then posts * the specified number of sends (ctx.msg_count) to the multicast group. kernel-3.18\include\, kernel.img__initcall_hello_init6 .initcall6.init .init .initcalls , static initcall_t *initcall_levels[] __initdata. The perf record / report result (for the cycles perf event) is: Gcc and clang will only auto-vectorize loops when the iteration count is known ahead of the loop. autovec: 1.52s. Abstract . This document is a reference manual for the LLVM assembly language. Getting Started. (Actually timed with _mm_store in the loop, not _mm_storeu, because storeu is slower on Merom even when the address is aligned. By defining VULKAN_HPP_NO_SETTERSbefore including vulkan.hpp, setter member functions will not be available within structs and unions. The default behaviour will soon change to that implied by the -altivec-compat=xl option Extend the VulkanHpp.natvis file to have vk::ArrayWrapper1D m, Custom views of Vulkan-Hpp objects in Visual Studio, Passing Arrays to Functions using ArrayProxy, UniqueHandle for automatic resource management, Extensions / Per Device function pointers, VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE, GCC >= 4.8.2 (earlier version might work, but are untested). Vulkan-Hpp is part of the LunarG Vulkan SDK since version 1.0.24. autovec: 2.98s. Still a good solution for instances where boost can't be used. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. We can also do much better for the "cleanup" of the last up-to-15 bytes left over after doing vectors of 16B: upper-casing is idempotent, so re-processing some input bytes is fine.

MySQL UDF . limitations under the License. they have to be functions in C++ - even if C allows them to be macros. Resource acquisition is initialization (RAII) is a programming idiom used in several object-oriented, statically-typed programming languages to describe a particular language behavior. So for short strings longer than 16B, this is dramatically faster than auto-vectorized. We can detect when our vector has any bytes with the high bit set, and in that case fall back to a scalar utf-8-aware loop for that vector. Sometimes the user has to pass a preallocated structure chain to query information. Vulkan-Hpp provides a per-function dispatch mechanism by accepting a dispatch class as last parameter in each function call. This has the major advantage that gcc can auto-vectorize it for any architecture, but the major disadvantage that it's slower for the usually-common case of small strings. If you're using a Vulkan version not yet supported by the Vulkan SDK you can find the Getting Started. For each Vulkan handle type vk::Type there is a unique handle vk::UniqueType which will delete the underlying Vulkan resource upon destruction, e.g. This is the third post in our Zero to main() series, where we bootstrap a working firmware from zero code on a cortex-M series microcontroller.. This either selects the dynamic (when it's 1) or the static (when it's not 1) DispatchLoader as the default one, as long as it's not explicitly specified by VULKAN_HPP_DEFAULT_DISPATCHER. In all other cases the extension suffix has not been removed. alias ("target")The alias variable attribute causes the declaration to be emitted as an alias for another symbol known as an alias target.Except for top-level qualifiers the alias target must have the same type as the alias. Here's how the same code looks with a constructor: With constructors for CreateInfo structures one can also pass temporaries to Vulkan functions like this: Beginning with C++20, C++ supports designated initializers. Vulkan-Hpp provides a constructor for these chains similar to the CreateInfo objects which accepts a list of all structures part of the chain. __initcall6_start, In that case, the generated vulkan.hpp is formatted using the .clang-format file located in the root directory of this project. In RAII, holding a resource is a class invariant, and is tied to object lifetime. The goal of the Vulkan-Hpp is to provide header only C++ bindings for the Vulkan C API to improve the developers Vulkan experience without introducing CPU runtime cost. Copyright 2015-2020 The Khronos Group Inc. That is, for e.g. In some cases, it also generates cleanup code (for example if stacked floating point registers are used as on x86). for 16 char strings (0.187s). This in turn is the dispatcher instance, which is defined by VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE, which has to be used exactly once in your sources. Neither the question not your answer mentions this restriction. What's the benefit of grass versus hardened runways? This conversion allows passing temporary structs to functions which can result in shorter code. 3.3 Device Cleanup 3.3.1 Driver Requirements: Device Cleanup 4 Virtio Transport Options 4.1 Virtio Over PCI Bus 4.1.1 Device Requirements: Virtio Over PCI Bus 4.1.2 PCI Device Discovery 4.1.3 PCI Device Layout 4.1.4 Virtio Structure PCI Capabilities 4.1.5 PCI-specific Initialization And Device Operation 4.2 Virtio Over MMIO Addams family: any indication that Gomez, his wife and kids are supernatural? I wouldn't do this. On X86-64 and AArch64 targets, this attribute changes the calling convention of a function. Getting Started. it accepts characters as arguments, strings are made up of characters, so you'll have to iterate over each individual character that when put together comprise the string, Using Boost.Text, which will work for Unicode text. How to characterize the regularity of a polygon? By defining VULKAN_HPP_ASSERT before including vulkan.hpp, you can change that to any function with the very same interface. __attribute__((packed))__attribute__((packed, aligned(1))) aligned(x) xx12 __attribute__((packed)) The original poster of the question is presumably long gone. Vulkan-Hpp is part of the LunarG Vulkan SDK since version 1.0.24. The file VulkanHpp.natvis provides a custom view on vk::Flags for Visual Studio. RegName is your string. The ODB system also defines two special-purpose languages: the ODB Pragma Language and ODB Query Language. An example is acquireNextImage2KHR, that can be used like this: As time passes, some vulkan functions might change, such that they start to support more result codes than vk::Result::eSuccess as a success code. You can then use the buffer to construct a std:string instance. If you don't need those functions, you can define VULKAN_HPP_NO_TO_STRING to prevent that inclusion. My loop reading from a std::string and writing to a char dstbuf[4096] makes sense for testing. Here are some code samples on how to use the ArrayProxy: Vulkan-Hpp generates references for pointers to structs. __attribute____attribute__ ((attribute-list)) module_init module_exit init_module cleanup_module alias ("target")The alias variable attribute causes the declaration to be emitted as an alias for another symbol known as an alias target.Except for top-level qualifiers the alias target must have the same type as the alias. The dst point can advance by a different amount than the src pointer, but once we get back to an aligned src pointer, we'll still just do unaligned vector stores to dst. Every vk-function gets a Dispatcher as its very last argument, which defaults to VULKAN_HPP_DEFAULT_DISPATCHER. __initcall7_start, for vk::Device::createBuffer there is vk::Device::createBufferUnique and for vk::allocateCommandBuffers there is vk::allocateCommandBuffersUnique. We can also do much better for the "cleanup" of the last up-to-15 bytes left over after doing vectors of 16B: upper-casing is idempotent, so re-processing some input bytes is fine. They might be a problem when operating in-place, because of a store-forwarding stall. std::basic_string has both a const and a mutable iterator (returned by cbegin() and begin() respectively, see. The pNext field is automatically set to the correct value: If one of the structures of a StructureChain is to be removed, maybe due to some optional settings, you can use the function vk::StructureChain::unlink(). Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. With this define you can specify whether the DispatchLoaderDynamic is imported or exported (see VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE). This will perform better than all the answers that use the global toupper function, and is presumably what boost::to_upper is doing underneath. To get the default there, a simple {} would suffice: All over vulkan.hpp, there are a couple of calls to an assert function. ), SSE only has a signed compare-greater, but we can still use the "unsigned There's a lot of scope for tuning this for different use-cases, depending on what the surrounding code wants, and the target microarchitecture. The names have been changed to 'e' + CamelCase with the VK_ prefix and type infix removed. Flag bits are handled like scoped enums with the addition that the. On 64-bit platforms this define is set to 1 by default and can be set to 0 to disable implicit conversions. Thanks for contributing an answer to Stack Overflow! This calling convention also behaves identical to the C calling convention on how arguments and return values are passed, but it uses a different set autovec: 2.07s // non-vector cleanup has 1 char to process, 15 char string: baseline: 1.08s. To learn more, see our tips on writing great answers. We do an unaligned load of the last 16B of the source, and store it into the dest buffer overlapping the last 16B store from the loop. Optionally install clang-format >= 11.0 to get a nicely formatted Vulkan-Hpp header. To use Vulkan-Hpp with extensions it's required to have either a library which provides stubs to all used Vulkan functions or to tell Vulkan-Hpp to dispatch those functions pointers. One of them should. I wrote this because it was fun, after answering the x86 asm Q&A. Asking for help, clarification, or responding to other answers. some string that you want converted. In addition to this the first letter of functions is lower case. If you have certain files where you want to use those functions nevertheless, you can explicitly include vulkan_to_string.hpp there. If you really need that functionality, and accept the reduced security, you can use this define to change the access specifier for m_mask from private to public, which allows using a Flags as a non-type template parameter. To use the DispatchLoaderDynamic as the default dispatcher (means: you don't need to explicitly add it to every function call), you need to #define VULKAN_HPP_DISPATCH_LOADER_DYNAMIC 1, and have the macro VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE exactly once in your source code to provide storage for that default dispatcher. vk::UniqueBuffer is the unique handle for vk::Buffer. 18.24 Defining target-specific uses of __attribute__; 18.25 Emulating TLS; 18.26 Defining coprocessor specifics for MIPS targets. For more information, see CHANGES.HTML. for cleanup of the last up-to-15 characters. Maybe the other form of to_upper_copy optimizes better, but I think it will always new/malloc space for the copy, so it's harder to test. (note the foot-note to it: "This disallows the common practice of providing a masking macro. blah blupp .. only way to do it in C++ is to provide a extern inline function.") dst != src (so we make a copy), but they don't overlap (and aren't nearby). As solution Vulkan-Hpp provides a template class vk::Flags which brings the standard operations like &=, |=, & and | to our scoped enums. ,., #include "stm32f10x.h" To ease creating such a DispatchLoaderDynamic, there is a little helper class DynamicLoader. In addition to this it checks at compile time if the spec allows the construction of such a pNext chain. With C++20, designated initializers are available. Coding style is very personal, and I wont force my views on anybody, but this is what goes for anything that I have to be able to maintain, and Id prefer it for most other things too. By defining VULKAN_HPP_NAMESPACE before including vulkan.hpp, you can adjust this. Does an Antimagic Field suppress the ability score increases granted by the Manual or Tome magic items? While this code may answer the question, providing additional context regarding why and/or how this code answers the question improves its long-term value. Byron, don't worry about the other comments. vulkan.hpp provides a couple of type traits, easing template programming: With the additional header vulkan_format_traits.hpp, a couple of trait functions on vk::Format are provided. __attribute__ ((fastcall)) void printnums "The numbers you sent are %d %d %d" call printf; stack cleanup add esp, 0x10 nop leave retn 0x04. As the two arguments were passed through the registers and only one parameter was pushed in the stack, the pushed value is being cleared by the retn instruction, as int is 4 bytes in size in x86 systems Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. This can be removed by defining VULKAN_HPP_NO_NODISCARD_WARNINGS before including vulkan.hpp. Your project's .h files. delay_, http://blog.csdn.net/richard_liujh/article/details/45669207- , http://blog.csdn.net/richard_liujh/article/details/45669207 If you're developing your code on a 64-bit platform, but want compile your code for a 32-bit platform without adding the explicit casts you can define VULKAN_HPP_TYPESAFE_CONVERSION to 1 in your build system or before including vulkan.hpp. To create a device you can now just write: Some functions allow more than just vk::Result::eSuccess to be considered as a success code. RESETREAS If, on the other hand, VULKAN_HPP_DISPATCH_LOADER_DYNAMIC is defined to something different from 1, VULKAN_HPP_DEFAULT_DISPATCHER is set to be DispatchLoaderStatic(). "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat", Compile main.cpp #include "delay.h" Feel free to submit a PR to add to this list. __attribute__((cleanup()))block What could be an efficient SublistQ command? If you explicitly set VULKAN_HPP_DEFAULT_DISPATCHER, you need to set VULKAN_HPP_DEFAULT_DISPATCHER_TYPE accordingly as well. That tuple then could easily be iterated. , It adds features like type safety for enums and bitfields, STL container support, exceptions and simple enumerations. Preliminary testing with x86-64 gcc 5.2 -O3 -march=native on a Core2Duo (Merom). Getting the compiler to emit nice code for the cleanup portion is tricky. I suggest you look into ICU, and difference between Simple and Full Case Mappings. __initcall0_start, This also works with C++98 after you replace the auto, use of the new non-const str.data(), and add a space to break the template closing (">>" to "> >") like this: std::for_each(str.begin(), str.end(), [](char & c){ c = ::toupper(c); }); std::transform(str.begin(), str.end(), str.begin(), ::toupper); The answer of @dirkgently is very inspiring, but I want to emphasize that due to the concern as is shown below. The only time this doesn't work is when the whole string is under 16B: Even when dst=src, non-atomic read-modify-write is not the same thing as not touching some bytes at all, and can break multithreaded code. As vulkan.hpp is pretty big, some compilers might need some time to digest all that stuff. This is because ::toupper has to look up the locale - because it might've been changed by a different thread - for every invocation, whereas here only the call to locale() has this penalty. Most of them are ports from the LunarG samples, but there are some more, like CreateDebugUtilsMessenger, InstanceVersion, PhysicalDeviceDisplayProperties, PhysicalDeviceExtensions, PhysicalDeviceFeatures, PhysicalDeviceGroups, PhysicalDeviceMemoryProperties, PhysicalDeviceProperties, PhysicalDeviceQueueFamilyProperties, and RayTracing. This calling convention also behaves identical to the C calling convention on how arguments and return values are passed, but it uses a different set manual: 0.335s, 127 char string: baseline: 8.91s. In RAII, holding a resource is a class invariant, and is tied to object lifetime. The sender then posts * the specified number of sends (ctx.msg_count) to the multicast group. Those tests are just compilation tests and are not required to run. manual: 0.925s, 128 char string: baseline: 9.00s.
