Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-09-17T12:46:27+00:00 2025-09-17T12:46:27+00:00 Ronan ro.cailleau@gmail.com 2025-09-17T12:46:27+00:00 urn:sha1:b5078d12127f4ab348b8d6d4c4e8139ba7bfb47f Fixes #8406 (and #8410). `AddressSpace`, `MemoryScope` and `AccessQualifier` are no longer `BaseType`. I added a new `__magic_enum` (very similar to `__magic_type`) syntax to be able to easily create values or these enums from the compiler. (I don't know if it was the right way to do it, but it works and the changes are small enough?). I had a weird bug: `tests/language-feature/capability/address-of.slang` was failing in `IRBuilder::_findOrEmitConstant(IRConstant& keyInst)`. When needing a new `u64(0)`, it did not find it in the `ConstantMap` first, but then failed to add it right after because it already existed in the map! But this was triggered by `IRPtrType* IRBuilder::getPtrType(IROp op, IRType* valueType, AccessQualifier accessQualifier, AddressSpace addressSpace)`, which is a strange coincidence... but I could not find the issue in what I did. I ended up bumping unordered_dense, and it solved the issue (so there was a bug in there). 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
