Use LOAD_LIBRARY_SEARCH_DEFAULT_DIRS for LoadLibraryExW (#8491)

2025-09-19T21:53:03+00:00

Before: - Uses `LOAD_LIBRARY_SEARCH_USER_DIRS` in `LoadLibraryExW`, which might cause exception if there is no pathes added by `AddDllDirectory()` After: - Use the composite flag `LOAD_LIBRARY_SEARCH_DEFAULT_DIRS`, which searches for several locations. - Will still search dir added by `AddDllDirectory()`, but avoids empty path seraching if there is no AddDllDirectory() calls.

Use wide char version of Windows API (#8390)

2025-09-08T17:24:05+00:00

This PR modernizes the Windows-specific code by replacing ANSI Windows API functions with their Unicode (wide character) counterparts. This change ensures proper handling of Unicode file paths and strings on Windows systems. ### File Operations (`source/core/slang-io.cpp`) - `DeleteFileA` → `DeleteFileW` - `GetTempPathA` → `GetTempPathW` - `GetTempFileNameA` → `GetTempFileNameW` - `RemoveDirectoryA` → `RemoveDirectoryW` - `SHFileOperationA` → `SHFileOperationW` - `GetModuleFileNameA` → `GetModuleFileNameW` with UTF-8 conversion ### Platform Operations (`source/core/slang-platform.cpp`) - `GetModuleHandleExA` → `GetModuleHandleExW` - `LoadLibraryExA` → `LoadLibraryExW` - `LoadLibraryA` → `LoadLibraryW` - `OutputDebugStringA` → `OutputDebugStringW` ### Runtime and Tools - `MessageBoxA` → `MessageBoxW` in slang-rt - `GetCurrentDirectoryA` → `GetCurrentDirectoryW` in slang-fiddle - String literal conversion to wide strings in vk-pipeline-create --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Gangzheng Tong Co-authored-by: slangbot Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Add check for backtrace availability (#8329)

2025-09-06T02:38:08+00:00

The header execinfo.h and the related backtrace functionality is not available on all linux platforms. In particular it's missing on musl linux and on Android before API version 33. This causes compilation errors on those platforms. With this change, we first check if backtrace functionality is available by checking if we are using glibc or a compatible Android version. Tested on manylinux_2_28 with glibc 2.28 and musllinux_1_2 with musl 1.2, has not been tested on Android. Co-authored-by: Yong He

Try both LoadLibrary functions on Windows (#8368)

2025-09-05T04:35:34+00:00

If a given library cannot be found using LoadLibraryExA then try again using LoadLibraryA. Return an error only if both of these failed.

Revert "Reduce the dependency to thread library (#8216)" (#8319)

This cause the pthread not found issue on old glibc build. This reverts commit 113327194d4cf750af6265a560615850a8e7e6fb.

Fix readlink missing include (#8260)

2025-08-22T17:57:19+00:00

On Linux, `slang-platform.cpp` compiles with libstdc++ only because `unistd.h` is being transitively included. It fails to compile with standard libraries that don't include `unistd.h` like libc++. This is the how it's being transitively included with libstdc++: ``` /home/mcvm/dev/slang/source/core/slang-platform.h /home/mcvm/dev/slang/source/core/../core/slang-string.h /home/mcvm/dev/slang/source/core/../core/slang-hash.h /home/mcvm/dev/slang/external/unordered_dense/include/ankerl/unordered_dense.h /usr/lib64/gcc/x86_64-unknown-linux-gnu/15.1.0/../../../../include/c++/15.1.0/memory /usr/lib64/gcc/x86_64-unknown-linux-gnu/15.1.0/../../../../include/c++/15.1.0/bits/shared_ptr_atomic.h /usr/lib64/gcc/x86_64-unknown-linux-gnu/15.1.0/../../../../include/c++/15.1.0/bits/atomic_base.h /usr/lib64/gcc/x86_64-unknown-linux-gnu/15.1.0/../../../../include/c++/15.1.0/bits/atomic_wait.h /usr/include/unistd.h ``` Tested building with `-stdlib=libc++` and `-stdlib=libstdc++`.

Reduce the dependency to thread library (#8216)

2025-08-20T16:28:30+00:00

Slang compiler doesn't use thread and we should declare the dependency to the thread library when we don't need it. The use of Thread is limited to the tools such as slang-test.
