From 9b434e50f02f9ec02ce230de9042ce7448bae451 Mon Sep 17 00:00:00 2001 From: ArielG-NV <159081215+ArielG-NV@users.noreply.github.com> Date: Fri, 15 Mar 2024 16:14:32 -0400 Subject: Implement raytracing extension(s); resolves #3560 for GLSL & SPIR-V targets (#3675) The following PR implements raytracing extensions (GLSL_EXT_ray_tracing, GLSL_EXT_ray_query, GLSL_NV_shader_invocation_reorder & GLSL_NV_ray_tracing_motion_blur); for GLSL & SPIR-V targets. Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets. notes of worth: * __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax. --- source/slang/slang-emit-c-like.cpp | 21 +++++++++++++++++++++ 1 file changed, 21 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 2019bfa8c..af53b545f 100644 --- a/source/slang/slang-emit-c-like.cpp +++ b/source/slang/slang-emit-c-like.cpp @@ -4268,6 +4268,27 @@ void CLikeSourceEmitter::computeEmitActions(IRModule* module, List& } } + for (auto inst : module->getGlobalInsts()) + { + // After emitting all structure types we need to emit all raytracing objects to + // ensure they are emitted before the layout location is referenced, otherwise, + // this can be a compile error if layout is emitted after location is referenced + // this is required since in GLSL, it is likley in a programs life time a raytracing + // object will never be referenced by name + for (auto dec : inst->getDecorations()) + { + switch (dec->getOp()) + { + case kIROp_VulkanRayPayloadDecoration: + case kIROp_VulkanRayPayloadInDecoration: + case kIROp_VulkanHitObjectAttributesDecoration: + case kIROp_VulkanCallablePayloadDecoration: + case kIROp_VulkanCallablePayloadInDecoration: + case kIROp_VulkanHitAttributesDecoration: + ensureGlobalInst(&ctx, inst, EmitAction::Level::Definition); + }; + } + } for(auto inst : module->getGlobalInsts()) { if( as(inst) ) -- cgit v1.2.3
