Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2019-08-09T16:40:35+00:00 2019-08-09T16:40:35+00:00 jsmall-nvidia jsmall@nvidia.com 2019-08-09T16:40:35+00:00 urn:sha1:97c46dd57c65ff596087c8b341926d1d2cbb6440 * Added CPU_REFLECTION test option - that has two versions of the reflection output depending on ptr size. * Added 'shared-library' test category. This category is disabled on CI targets that have issues. 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.
