Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2019-09-18T15:40:59+00:00 2019-09-18T15:40:59+00:00 jsmall-nvidia jsmall@nvidia.com 2019-09-18T15:40:59+00:00 urn:sha1:31c7abcc27a33d63ac8d335387a0ce7b3ad74954 * WIP: Improving CPU performance/ABI * Optionally output code on CPU for groupThreadID and groupID. * Added ability to set compute dispatch size on command line for render-test. Dispatch compute tests taking into account dispatch size. Added test for semantics are working. * Test using GroupRange. * Fix problem with adding \n for externa diagnostic - to do it if there isn't a \n at the end. Change the ouput order (put result before) so last value is diagnostic string. * Made GroupRange the default exposed CPU ABI entry point style. Removed CPU_EXECUTE test style -as tested via the now cross platform render-test * Split out execution from setup for execution to improve perf. * For better code coverage/testing test all styles of CPU compute entry point. * Improve documentation for ABI changes for CPU code. Add 'expecting' to error message from review. * Fix small typos. 2019-08-08T21:23:03+00:00 jsmall-nvidia jsmall@nvidia.com 2019-08-08T21:23:03+00:00 urn:sha1:41247c3942210df33b9e3dd733eafb23573a4f2f * Expanded prelude for some other resource types. Disable C++ output for ParameterGroup. * WIP: Layout for CPU. * Fixes to CPU layout. * WIP: The uniform is output, but the variable definition is not. * WIP: Entry point parameters to global scope in C++. Handling of resource types (in so far as outputting) * Some discussion of ABI and different input types. * WIP: More C++ support around resource types. * WIP: Split up variables into different structures on emit. * WIP: Emitting C++ with wrapping up of 'Context' * WIP: C++ code has access to semantic values. Wrap in struct so can use method calls to pass shared state. Disable legalizeResourceTypes and legalizeExistentialTypeLayout * Fix structured buffer layout for CPU. * Remove testing/handling of global uniforms on CPU path. Typo fix. Changed CPU tests to use new CPU calling convention. * Check globals are working. Initalize context to zero globals. * Order the global parameters for C++ ouput by their layout. Note - that layout isn't quite working correctly because the StructuredBuffer<int> the int seems to be consuming uniform space. * Work around for reflection not having all data needed for layout ordering for C++ code. * Output constant buffers as pointers. * Entry point parameters accessed through pointer to struct. * WIP: Layout for CPU is reasonable for test case. * Only output 'f' after float literal if type marks as a float. * Cast construction works on C++. * Made IntrinsicOp::ConvertConstruct to make intent clearer. * C++ handling construction from scalar. Handle access of a scalar with .x. Check default initialization. * Comment about need for split of kIROp_construct. Release build works. * Added support from constructVectorFromScalar to C/C++ target. * Handling of in/out in C/C++. * First pass documentation CPU support. * Improvements to C++/C slang code generation documentation. * Small doc change to include need for mechansim to specify cpp compiler path. * Better handling of swizzling - allow swizzling a scalar into a vector. 2019-07-17T14:26:37+00:00 jsmall-nvidia jsmall@nvidia.com 2019-07-17T14:26:37+00:00 urn:sha1:749634a2a6e03acf435c39f78b933a01b90a7440 * WIP: Adding support for C/C++ compilation to slang API. * Removed BackEndType in test harness -> use SlangPassThrough to identify backends Only require stage for targets that require it. Detection of all different backends. * Windows/Unix create temporary filename. * WIP: Output CPU binaries. * Added a pass-through c/c++ test. * Compile C++/C and store in temporary file. * Read the binary back into memory. * Set debug info and optimization flags for C/C++. Make the CPPCompiler debug/optimization levels match slangs. * Handling of include paths and math precision. * Dumping c++/c source and exe/shared library. * Put hex dump into own util. * End to end pass through c compilation test. * WIP: Simple execute test working on Linux/Unix. * Fix typo on linux. * WIP: To compile slang to cpp shared library. Report backend compiler errors. * Compiles slang -> cpp and loads as shared library. * Fix problem on c-cross-compile test because prelude is now included with <> quotes. * Run slang generated cpp code - using hard coded data. * Added cpp-execute-simple, and test output. * Fix warning that broke win32 build. * Fix compilation problem on osx.
