From 1b01ff909afa1eb6700c0dc947e679b9c3890880 Mon Sep 17 00:00:00 2001 From: jsmall-nvidia Date: Tue, 27 Jun 2023 11:28:14 -0400 Subject: Pointer layout support (#2930) * WIP looking at reflection with pointers. * Added GetPointerLayout. * Initial test via reflection with layout of ptr type. * WIP handles ptrs to types that have layout that hasn't been completed. * Move tests to ptr. * WIP try to take into account lowering correctly between AggTypeDecl and Type, but doesn't quite work. * WIP a different path to handling recursive lowering problem with Ptr. * Fix issues with reflection output. * Small tidy. * Fix for infinite recursion issue. * Lower IRPointerTypeLayout * Working with generics. Has a hack to work around Layout around Ptr in IR. The reflection around the generic - the name isn't much use, it should probably have the generic parameters, but that would require getName to do something more sophisticated. * Fix issue around calling finishOuterGenerics to early. * Remove feature/ptr test. * Fix type legalization being an infinite loop with Ptr self referencing. * Disable the pointer self reference test because produces an infintie loop on emit. * Fixed comment based on review. * Fix for issue with emit and pointers causing infinite recursion. --- tests/reflection/ptr/ptr-self-reference.slang | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 tests/reflection/ptr/ptr-self-reference.slang (limited to 'tests/reflection/ptr/ptr-self-reference.slang') diff --git a/tests/reflection/ptr/ptr-self-reference.slang b/tests/reflection/ptr/ptr-self-reference.slang new file mode 100644 index 000000000..437b7d61b --- /dev/null +++ b/tests/reflection/ptr/ptr-self-reference.slang @@ -0,0 +1,17 @@ +//TEST(64-bit):REFLECTION:-stage compute -no-codegen -target host-callable -entry computeMain + +struct SomeStruct +{ + int payload; + Ptr next; +}; + +RWStructuredBuffer inputBuffer; + +RWStructuredBuffer outputBuffer; + +[numthreads(4, 1, 1)] +void computeMain(uint3 dispatchThreadID : SV_DispatchThreadID) +{ + outputBuffer[dispatchThreadID.x] = int(dispatchThreadID.x); +} \ No newline at end of file -- cgit v1.2.3
