"aliases" are used in two places: one for "opname" and another for "enumerants". This commit itself wouldn't do anything until we integrate new commits from SPIRV-Header repo. 2024-01-19T00:46:00+00:00 Yong He yonghe@outlook.com 2024-01-19T00:46:00+00:00 urn:sha1:c5c1a25ab6d0e509e893d737a679ac47949df2f6 * Capability def parsing & codegen + disjoint sets This change adds a capability definition file, and a code generator to produce C++ code that defines the capability enums and necessary data structures around the capabilities. Extends the existing CapabilitySet class to support expressing disjoint sets of capabilities. This sets up for the next change that will enhance our type checking with reasoning of capability requirements. * Fix cmake. * Fix warning. * Fix. * Fix isBetterForTarget to prefer less specialized option. * Fix. * Fix premake. * Fix intrinsic. * Fix vs sln file. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-08-28T22:05:26+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-08-28T22:05:26+00:00 urn:sha1:508dc3a95de50de4a4d07d0a72a18e40d55b0e2e * Add -spirv-core-grammar option to load alternate spirv defs Also embed a version to use by default * Use perfect hash for spv op lookup * Neaten perfect hash embedding * Refactor spirv grammar lookup in preperation for more kinds of lookups * Load spirv capability list from spec * Add all SPIR-V enums to lookup table * regenerate vs projects * appease msvc * Use string slices for spir-v core grammar lookups * wiggle * comment * Add OpInfo for spv ops * regenerate vs projects * Embed op names * Add min/max operand counts and enum categories to spirv info * neaten * Operand kinds for spirv ops * Store and embed all information relating to spirv enums and qualifiers * Use SPIR-V spec to position instructions in spirv_asm blocks * Neaten spir-v info embedding * Neaten perfect hash embedding * Add assignment syntax to spirv_asm snippets * Better errors for spirv_asm parser * Add warning for too many operands in spirv asm * squash warnings * neaten * test wiggle * Lookup enums for spirv * Put OpCapability and OpExtension in the correct place for spirv_asm blocks * Tests for OpCapability and OpExtension * ci wiggle * Add expected failure * Allow raising immediate values to constant ids where necessary in spirv_asm blocks * Allow bitwise or expressions and numeric literals in spirv_asm blocks * test numeric literals * Fix memory issues. * fix. --------- Co-authored-by: Yong He <yonghe@outlook.com> 2023-08-25T15:49:02+00:00 Yong He yonghe@outlook.com 2023-08-25T15:49:02+00:00 urn:sha1:036abc85ba1db9c8c06289f0a0492e9a95a228b9 * Spirv Capability lookup. * Fix. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-08-16T00:57:47+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-08-16T00:57:47+00:00 urn:sha1:45d9961a6a86d184248ef84f6a07125b0c224f97 * Correct namespace for getClockFrequency * missing const * Add missing assignment operator * Remove unused variables * Return correct modified variable * Use stable hash code for file system identity * terse static_assert * Structured binding for map iteration * Make (==) and getHashCode const on many structs * Add ConstIterator for LinkedList * Replace uses of ItemProxy::getValue with Dictionary::at * Extract list of loads from gradientsMap before updating it * Const correctness in type layout * Add unordered_dense hashmap submodule * Use wyhash or getHashCode in slang-hash.h * refactor slang-hash.h * Use ankerl/unordered_dense as a hashmap implementation Notable changes: - The subscript operator returns a reference directly to the value, rather than a lazy ItemProxy (pair of dict pointer and key) slang-profile time (95% over 10 runs): - Before: 6.3913906 (±0.0746) - After: 5.9276123 (±0.0964) * 64 bit hash for strings So they have the same hash as char buffers with the same contents * Narrowing warnings for gcc to match msvc * revert back to c++17 * Correct c++ version for msvc * Use path to unordered_dense which keeps tests happy * Do not assign to and read from map in same expression * Remove redundant map operations in primal-hoist * Split out stable hash functions into slang-stable-hash.h * 64 bit hash by default * regenerate vs projects * Correct return type from HashSetBase::getCount() * correct width for call to Dictionary::reserve * Use stable hash for obfuscated module ids * Signed int for reserve * clearer variable naming * Parameterize Dictionary on hash and equality functors * Allow heterogenous lookup for Dictionary * missing const * Use set over operator[] in some places * Remove unused function * s/at/getValue 2023-03-28T01:39:44+00:00 Yong He yonghe@outlook.com 2023-03-28T01:39:44+00:00 urn:sha1:84dc318576e19ef1f86f6b012ba911c4b63f788d Co-authored-by: Yong He <yhe@nvidia.com> 2023-02-09T05:16:30+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-02-09T05:16:30+00:00 urn:sha1:fbe31ada800b3417d10a24f6c0481d3cb6b161e4 * Add Slang::List::stableSort * Use stable sort in generation of lookup tables * Disable newline translation when writing lookup tables 2023-02-03T04:18:49+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-02-03T04:18:49+00:00 urn:sha1:a00dc69ca8dfbc346940c7d03d67c1cb229577fb * s/emititng blobal/emitting global * Use SPIR-V opcode names rather than numbers * regenerate Visual Studio project files * Use names for extended SPIR-V GLSL instructions * Add missing operand for SPIR-V extended instruction * Add warning aginst modifying generated hashing files * Squash warnings on MSVC
