Too many changes to list, but broadly:
* Remove Intel GPU support from the compiler
* Add AMD GPU support to the compiler
* Remove Intel GPU host code
* Add AMD GPU host code
* More device instructions. From 40 to 68
* More host functions. From 48 to 184
* Add proof of concept implementation of OptiX framework
* Add minimal support of cuDNN, cuBLAS, cuSPARSE, cuFFT, NCCL, NVML
* Improve ZLUDA launcher for Windows
* Update ze_loader.lib to the newest version
* Export _ptsz/_ptds for which we have a legacy stream implementations
* Stop producing build logs if we are not looking at them anyway
Improve injector&redirector so it's no longer required to manually mess with files if the application links nvcuda.dll. Additionally inject into child processes
zluda_dump can already create traces of GPU execution, this script can replay those traces.
Additionally, changed added just enough code in core ZLUDA to support simple PyCUDAexecution
Fixes issues pointed out in #27:
* spirv_tools-sys was build in non-test profiles
* By default ZLUDA dll has a wrong name
* We relied on third-party OpenCL installation on Windows
* We encouraged building debug configuration
* We didn't provide build information for developers (cmake, python, submodules)
Two changes:
* Fixes to builtins generation that I forgot to include in #21
* Marking of ld/st as aligned - this gives a big performance boost in GeekBench SFFT
We currently directly map PTX special registers: %ntid, %tid, etc. to SPIR-V builtins with type OpTypeVector %uint 4.
This is wrong and leads to a silent corruption, which fails e.g. Depth of Field in GeekBench
Current code has a problem with handling vector members: "b.x" in "mov.u32 a, b.x". This functionality has been kinda tacked-on and has annoying issues:
* vector members support is only limited to being source of movs (so "add.u32 a.x, b.x, c.y" will not work)
* the width of "b" in "b.x" is not known, which led to some "interesting" workarounds
* passes can either convert all member accesses to other member accesses or to temporaries. No way to convert some member accesses to temporaries (which we need for an important fix)
This commit solves all this
