From 41247c3942210df33b9e3dd733eafb23573a4f2f Mon Sep 17 00:00:00 2001 From: jsmall-nvidia Date: Thu, 8 Aug 2019 17:23:03 -0400 Subject: WIP: Preliminary Slang -> C++ code generation (#1009) * 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 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. --- tests/cross-compile/cpp-execute.slang | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'tests/cross-compile/cpp-execute.slang') diff --git a/tests/cross-compile/cpp-execute.slang b/tests/cross-compile/cpp-execute.slang index 1c90c8dd2..2700aa49f 100644 --- a/tests/cross-compile/cpp-execute.slang +++ b/tests/cross-compile/cpp-execute.slang @@ -62,11 +62,12 @@ struct Thing float b; }; +//TEST_INPUT:ubuffer(data=[0 0 0 0], stride=4):dxbinding(0),glbinding(0),out +RWStructuredBuffer outputBuffer; + [numthreads(4, 1, 1)] void computeMain( - uint3 dispatchThreadID : SV_DispatchThreadID, -//TEST_INPUT:ubuffer(data=[0 0 0 0], stride=4):dxbinding(0),glbinding(0),out - RWStructuredBuffer outputBuffer) + uint3 dispatchThreadID : SV_DispatchThreadID) { uint tid = dispatchThreadID.x; -- cgit v1.2.3
