* HLSL Intrinsic coverage test improvements (#1206)jsmall-nvidia2020-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | * Fix CPP construct when matrix type. * Test intrinsics on float matrices. * Fix typo in _areNearlyEqual test. Increased default sensitivity. Added matrix-float test. * Matrix double test. Fixed some issues with CUDA. * Added reduced intrinsic version of matrix-double test. * Improve matrix double coverage. Test reflect/length etc on vector float. * * Added literal-float test. * Added vector double test * Improved coverage of vector/matrix tests * Disable Dx11 double-vector test because fails on CI. * Disable literal-float, because on CI fails.
* Literal handling improvements (#1202)jsmall-nvidia2020-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * WIP: 64 literal diagnostic and truncation. * Improve how integer truncation is handled/supported. Added literal-int64.slang test. Set a suffix on all literals. Fixed problem on C++ based targets where l suffix was not the same as int() cast. So on C++ derived emitters, int() is used instead of l suffix to have same behavior across targets. * Add literal diagnostic testing. * Allow lexer to lex - in front of literals. * Fix lexing and converting int literal with -. * Too large small values of floats become inf. Handling writing inf types out on different targets. Add function to deterimine if a float literals kind. * Roll back the support of lexer lexing negative literals. * Fixed tests broken because of diagnostics numbers. Improved _isFinite * Fix compilation on linux. * Fix problem with abs on linux - use Math::Abs. * Fix typo. * * Improve warnings for float literals zeroed * Improved 64 bit type documentation * Handle half * Improved comments * Fixed tests broken * Use capital letters for suffixes. * Make default behavior on outputting a int literal that is an 'int32_t' is cast (not suffix) to avoid platform inconsistencies. Improve documentation for 64 bit types. Make tests cover material in docs. * Fixed tests. * Rename FloatKind::Normal -> Finite * Fix half zero check.
* 64 bit types doc (#1194)jsmall-nvidia2020-01-31
| | | | | | | | | | | | | | | | * * For integer literals add postfix, and use unsigned/signed output appropriately * Extend GLSL extension handling by type, and for adding 64 bit int extensions * Added tests for int/uint64 types * Add explicit Int/UInt64 emit functions to avoid ambiguity. * Fix uint64_t intrinsics on CUDA/C++. * WIP 64 bit types documentation. * Testing int64 intrinsic support. * Dx12 Dxil sm6.0 does actually support int64_t.
* Synthesizing CUDA tests (#1183)jsmall-nvidia2020-01-28
| | | | | | | | | | | | | | | | | | | | * When using setUniform clamp the amount of data written to the buffer size. * CUDA implement StructuredBuffer/ByteAddressBuffer as pointer/count as is on CPU. Allow bounds check to zero index. Update docs. * Synthesize tests. * Fix bug in CUDA output. * Fixing more tests to run on CUDA. * Added BaseType for layout of Vector and Matrix - as they are held as int32_t vector array types. * Enable unbound array support on CUDA. * Added unsized array support for CUDA documentation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added hlsl-intrinsic test folder. Enabled ceil as works across targets. * log10 support. * Fix float % on CPU/CUDA to match HLSL which is fmod (not fremainder). * Added log10 tests back to scalar-float.slang * Don't add the ( for $Sx - it's clearer what's going on without it. * Works on CUDA/CPU.

| | | | | | | * Simple testing of unbounded array of array on GPU. * Fix problem on CPU targets around NonUniformResourceIndex Use the unbounded-array-of-array-syntax test for CPU and GPU tests.

* Clean up some behavior of operator% (#1060)Tim Foley2019-09-18
| | | | | | | | | | | | | | | | | | | | | | | Work on #1059 The `%` operator in the Slang implementation had several issues, and this change tries to address some of them: * Renamed most occurences of "mod" describing this operator to be "rem" for "remainder" to better match its semantics in HLSL * Split the operator into distinct integer and floating-point variants (`IRem` and `FRem`) to simplify having different codegen for the two * Added floating-point variants of `operator%` and `operator%=` to the stdlib. * Added custom C++ codegen for `kIROp_FRem` such that it maps to the standard C/C++ `remainder()` function * Added custom GLSL codegen so that `kIROp_FRem` maps to the GLSL `mod()` function (which isn't correct...) * Added a test case to confirm that D3D11, D3D12, and CPU targets all agree on the definition of floating-point `%` * Fixed `render-test-tool` to allow a negative integer in a `data=...` specification. This didn't end up being used in the final test, but still seems like a good fix. * Added a customized baseline for the Vulkan flavor of that test to confirm that we are *not* compiling correctly to SPIR-V just yet Addressing the correctness of the output for GLSL/SPIR-V will have to come as a later change given that the operation we want is not exposed directly by unextended GLSL.
* Improvements to testing and ABI for CPU (#1057)jsmall-nvidia2019-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

Fixed debugging into source for generated C++. buffer-layout.slang works. * Added cpu test result. * Remove some commented out code. Comment on next fixes. * Improvements to reflection CPU code. * C++ working with ByteAddressBuffer. * Enabled more compute tests for CPU. * Enabled more compute tests on CPU. Added support for [] style access to a vector. * Enabled more CPU compute tests. * Handling of buffer-type-splitting.slang Named buffers can be paths to resources * Fix some warnings, remove some dead code. * Fix problem with verification of number of operands for asuint/asint as they can have 1 or 3 operands. asdouble takes 2. * Fix handling in MemoryArena around aligned allocations. That _allocateAlignedFromNewBlock assumed the block allocated has the aligment that was requested and so did not correct the start address.
* User defined downstream compiler prelude (#1028)jsmall-nvidia2019-08-20
* Added setDownstreamCompilerPrelude Renamed setPassThroughPath to setDownstreamCompilerPath. Fixed tests. Added prelude directory & code to TestToolUtil to setup default preludes for testing/command line apis. * Fix merge problem * Remove hacks to make prelude work by adding a search path as no longer needed with 'user prelude'. * Split up prelude into scalar intrinsics, and types. Use slang.h for main header. slang-cpp-prelude.h can now just include what it needs (relative to prelude directory) and define the few remaining things/work arounds. * Fix typo.
