From 2c2294d3310b24fd73cd41ec51338a736f3a2886 Mon Sep 17 00:00:00 2001 From: Ellie Hermaszewska Date: Tue, 5 Sep 2023 23:26:59 +0800 Subject: SPIR-V image operations (#3163) * Add __truncate and __sampledType for spirv_asm Allows some texture tests to start passing * add __isVector Currently unused * Add 1-vector legalization pass (WIP) * Add capabilities for image types * neaten instruction dumping * add 1-vector test * Add a couple of cases to vec1 legalization * Remove texture tests from expected failures * comment * regenerate vs projects * Remove redundant define form synchapi emulation * refactoring image methods * All sample functions refactored * Remove incorrect glsl intrinsics Partially addresses https://github.com/shader-slang/slang/issues/3174 * __subscript image ops via writing funcs * Extract texture struct writing from core.meta.slang * Abstract out cuda intrinsic * Remvoe erroneous call to opDecorateIndex * spirv asm IR utils * Correct position of loads for SPIR-V asm inst operands * Raise constructors to global scope during spir-v legalization * Correct snippet output * Implement most texture sampling ops for SPIR-V * Legalize 1-vectors for glsl too * Make SPIR-V inst operands non-hoistable * Better 1-vector legalization * Put textures in ptrs for spirv * insert missing break * Add vec1 legalization test * Add some missing pieces to slang-ir-insts * Greatly neaten vec1 legalization * a * Neaten vec1 legalization * Add image read and write intrinsics for spir-v * Squash warnings * regenerate vs projects * Drop redundant guards * Drop 5 tests from expected failure list * Inst numbering changes to cross compile tests * vec1 legalization tests only on vk * Correct location of asm op emit * Inline constant in spirv-asm * Correct signedness for lane in wave intrinsics * Extract element from float1 for cuda * squash warnings * Neaten spirv-emit * dedupe more capabilities * warnings * neaten assert * comments * comments --- source/slang/slang-ir.cpp | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) (limited to 'source/slang/slang-ir.cpp') diff --git a/source/slang/slang-ir.cpp b/source/slang/slang-ir.cpp index d3cfea6e9..6777c0b3a 100644 --- a/source/slang/slang-ir.cpp +++ b/source/slang/slang-ir.cpp @@ -5772,6 +5772,31 @@ namespace Slang return i; } + IRSPIRVAsmOperand* IRBuilder::emitSPIRVAsmOperandSampledType(IRType* elementType) + { + SLANG_ASSERT(as(m_insertLoc.getParent())); + const auto i = createInst( + this, + kIROp_SPIRVAsmOperandSampledType, + getTypeType(), + elementType + ); + addInst(i); + return i; + } + + IRSPIRVAsmOperand* IRBuilder::emitSPIRVAsmOperandTruncate() + { + SLANG_ASSERT(as(m_insertLoc.getParent())); + const auto i = createInst( + this, + kIROp_SPIRVAsmOperandTruncate, + getVoidType() + ); + addInst(i); + return i; + } + IRSPIRVAsmInst* IRBuilder::emitSPIRVAsmInst(IRInst* opcode, List operands) { SLANG_ASSERT(as(m_insertLoc.getParent())); @@ -6631,6 +6656,14 @@ namespace Slang case kIROp_SPIRVAsmOperandResult: dump(context, "result"); return; + case kIROp_SPIRVAsmOperandTruncate: + dump(context, "__truncate"); + return; + case kIROp_SPIRVAsmOperandSampledType: + dump(context, "__sampledType("); + dumpInstExpr(context, inst->getOperand(0)); + dump(context, ")"); + return; } dump(context, opInfo.name); -- cgit v1.2.3
