From 66d4466d680bcd97b7eb561f08bd6da80a1d6c4e Mon Sep 17 00:00:00 2001 From: Tim Foley Date: Thu, 7 Jan 2021 12:18:55 -0800 Subject: Add support for [noinline] attribute (#1650) This adds the `[noinline]` attribute to the front-end, and passes it through when generating HLSL output. Notes: * This change doesn't include a test since the dxc version I have locally parses `[noinline]` but then generates DXIL that fails validation. * This change doesn't include logic to handle `[noinline]` for other targets. Notably, SPIR-V has decorations that convey the same intention, but we don't yet take advantage of the GLSL extension(s) that would let us generate those decorations. * By necesstiy, `[noinline]` is only a "strong suggestion" and not actually something the compiler can ever guarantee/enforce. --- source/slang/slang-emit-c-like.cpp | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'source/slang/slang-emit-c-like.cpp') diff --git a/source/slang/slang-emit-c-like.cpp b/source/slang/slang-emit-c-like.cpp index facb8a710..44564e575 100644 --- a/source/slang/slang-emit-c-like.cpp +++ b/source/slang/slang-emit-c-like.cpp @@ -3160,6 +3160,7 @@ void CLikeSourceEmitter::emitSimpleFuncImpl(IRFunc* func) auto name = getName(func); + emitFuncDecorations(func); emitType(resultType, name); emitSimpleFuncParamsImpl(func); emitSemantics(func); @@ -3268,6 +3269,7 @@ void CLikeSourceEmitter::emitFuncDecl(IRFunc* func) auto name = getName(func); + emitFuncDecorations(func); emitType(resultType, name); m_writer->emit("("); @@ -3344,6 +3346,15 @@ void CLikeSourceEmitter::emitFunc(IRFunc* func) } } +void CLikeSourceEmitter::emitFuncDecorations(IRFunc* func) +{ + for(auto decoration : func->getDecorations()) + { + emitFuncDecorationImpl(decoration); + } +} + + void CLikeSourceEmitter::emitStruct(IRStructType* structType) { // If the selected `struct` type is actually an intrinsic -- cgit v1.2.3
