From 00bd481e001e8c0b8008eaff5a38fa37963e6f99 Mon Sep 17 00:00:00 2001 From: Ellie Hermaszewska Date: Tue, 15 Aug 2023 20:28:42 +0800 Subject: SPIR-V WIP (#3064) * Add type layout for structured buffer * Default to generating spirv directly * vk test for compute simple * Add spirv-dis as a downstream compiler * Emit Array types in SPIR-V * makevector for spirv * Dump whole spirv module on validation failure * register array types todo, use emitTypeInst * Neater formatting for unhandled inst printing * break out emitCompositeConstruct * Correct array type generation * neaten * Allow getElement for vector * Remove unused * Allow predicating target intrinsics on types * Consider functions with intrinsics to have definitions We need to specialize these if they are predicated on types * Correct array type generation * makeArray for spir-v * replace getElement with getElementPtr for spirv * Correct translation of field access for spirv * Push layouts to types for spirv * Spirv intrinsics * operator now makes a pointer * Add structured buffer of struct test * Preserve type layout in spirv structured buffer legalization * neaten * makeVectorFromScalar for SPIRV * placeholder for layouts on param groups * More type safe spirv op construction * Know that constants and types only go in one section * Remove emitTypeInst * Add todo for spirv sampling * Add links to spirv documentation on emit functions * OpTypeImage support for SPIR-V * Add simpler texture test for spirv * s/spirv_direct/spirv/g * Allow several string literals in target_intrinsic * Handle global params without a var layour for SPIR-V For example groupshared vars * uint spirv asm type * Add todo for isDefinition It is currently too broad * Some atomic op spirv intrinsics * Strip ConstantBuffer wrappers for spirv * Add todo for matrix annotations * Do not associate decorations insts with spirv counterparts * Correct entry point parameter generation * Spelling * Assert that fieldAddress is returning a pointer * Add error for existential type layout getting to spir-v emit * Add IRTupleTypeLayout Unused so far * Allow getElementPtr to work with vectors * Correct target name in test * Hide default spirv direct behind a premake option --default-spirv-direct=true * Do not insert space at start of intrinsic def * Correct asm rendering in tests * remove redundant option * Emit directly from direct test * Add source language options for spirv-dis * Add comments to spirv dis * Add dead debug print for before spirv module * Correct asm rendering in tests * s/spirv_direct/spirv/g * Only specialize intrinsic functions with predicates * regenerate vs projects * squash warnings * squash warnings * remove duplication * Silence warnings from msvc * squash warnings * Overload for zero sized array * More msvc warnings * warnings * Add spirv-tools to path for tests * Do not be specific about dxc version for diag test * Normalize line endings from spirv-dis * Correct filecheck matches * Temporarily disable two spirv tests Failing on CI, undebuggable hang :/ * Do not emit storage class more than once for spirv snippet * Do not pass spir-v to spirv-dis by stdin * Do not get spirv-dis output via stream, use file * normalize file endings in spirv-dis output --- slang.h | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'slang.h') diff --git a/slang.h b/slang.h index b799b5483..2faff82e3 100644 --- a/slang.h +++ b/slang.h @@ -699,9 +699,14 @@ extern "C" /* When set, will dump out the IR between intermediate compilation steps.*/ SLANG_TARGET_FLAG_DUMP_IR = 1 << 9, - /* When set, will generate SPIRV directly instead of going through glslang. */ + /* When set, will generate SPIRV directly rather than via glslang. */ SLANG_TARGET_FLAG_GENERATE_SPIRV_DIRECTLY = 1 << 10, }; +#if defined(SLANG_CONFIG_DEFAULT_SPIRV_DIRECT) + constexpr static SlangTargetFlags kDefaultTargetFlags = SLANG_TARGET_FLAG_GENERATE_SPIRV_DIRECTLY; +#else + constexpr static SlangTargetFlags kDefaultTargetFlags = 0; +#endif /*! @brief Options to control floating-point precision guarantees for a target. @@ -737,6 +742,7 @@ extern "C" SLANG_SOURCE_LANGUAGE_C, SLANG_SOURCE_LANGUAGE_CPP, SLANG_SOURCE_LANGUAGE_CUDA, + SLANG_SOURCE_LANGUAGE_SPIRV, SLANG_SOURCE_LANGUAGE_COUNT_OF, }; @@ -4152,7 +4158,7 @@ namespace slang SlangProfileID profile = SLANG_PROFILE_UNKNOWN; /** Flags for the code generation target.
