Update build to allow setting external paths (#6528)

2025-03-07T03:16:27+00:00

* Update build to allow setting external paths Update the build to allow setting user-specific paths for the external modules. This allows building Slang without also fetching the external modules, assuming they are already present elsewhere locally.

Fix prelude generation by using relative paths for including `slang.h` (#4973)

2024-08-30T23:58:07+00:00

* Change `slang.h` path in `slang-common.h` to allow `slang-embed` to resolve correctly. * Change `slang.h` path in all slang/core files --------- Co-authored-by: Yong He

Move the file public header files to `include` dir (#4636)

2024-07-17T17:53:19+00:00

* Move the file public header files to `include` dir Close the issue (#4635). Move the following headers files to a `include` dir located at root dir of slang repo: slang-com-helper.h -> include/slang-com-helper.h slang-com-ptr.h -> include/slang-com-ptr.h slang-gfx.h -> include/slang-gfx.h slang.h -> include/slang.h Change cmake/SlangTarget.cmake to add include path to every target, and change the source file to use "#include " to include the public headers. The source code update is by the script like follow: ``` fileNames_slang=$(grep -r "\".*slang\.h\"" source/ -l) for fileName in "${fileNames_slang[@]}" do echo "$fileName" sed -i "s/\".*slang\.h\"/\"slang\.h\"/" $fileName done ``` * Fix the test issues * Fix cpu test issues by adding include seach path * Update cmake to not add include path for every target Also change "#include " to "include "slang.h" " to make the coding style consistent with other slang code. * Change public include to private include for unit-test and slang-glslang

Allow bitwise or expressions and numeric literals in spirv_asm blocks (#3157)

Use ankerl/unordered_dense as a hashmap implementation (#3036)

2023-08-16T00:57:47+00:00

* 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
