Implemented #pragma warning (#6748)

2025-04-24T22:48:37+00:00

* Implemented #pragma warning Based on https://learn.microsoft.com/en-us/cpp/preprocessor/warning?view=msvc-170 * Make #pragma warning work with #includes. - SourceLoc are not sorted by inclusion order. - Construct a mapping from SourceLoc to "absolute locations" that are sorted by inclusion order (roughly represents a location in a raw file with all #include resolved). - The absolute location can be used in the pragma warning timeline * Added preprocessor #pragma warning tests. - Fixed #pragma warning (push / pop) SourceLoc - Fixed unused directiveLoc in #pragma warning parsing * #pragma warning: Added some comments and fixed some typos * Cleaned #pragma warning preprocessor implementation. --------- Co-authored-by: Yong He

Slang: Support UTF-8 with Byte Order Markers (#4135)

2024-05-14T18:05:58+00:00

Slang APIs are documented as taking UTF-8 encoded shader source, though it's not explicitly documented whether it is allowed to include a BOM (Byte Order Marker). This change adds support for UTF-8 BOM markers by virtue of disposing of BOM data. As a bonus, UTF-16 input which can cleanly decode to UTF-8 is now also accepted. Throwing out the BOM on input is done by leveraging existing functionality in "determineEncoding()", however a bug exists there for null-terminated single character input, where the null byte caused a heuristic to guess UTF-16, even though the null byte isn't part of the string. The bug in "determineEncoding" is fixed by only guessing when bytes >= 2 and not looking past the end of the buffer. The 'implicit-cast' test was mistakenly relying on the bug to pass, as its expected file was being read as UTF16 and cropped to zero length due to the bug. The expected output of implicit-cast is updated to pass with the bug fix in place. The decoding of UTF-16 to UTF-8 is done through an existing 'decode' method. This change fixes a bug in UTF16-LE 'decode' where it was decoded as if it were Big-Endian. Adds 3 small tests to ensure the compiler doesn't choke on source files in UTF-8 (with BOM), UTF16-LE, or UTF16-BE. Bonus: Fixes a bug in diagnostic reporting where hex values were incorrectly translated to text, leading to incorrect, possibly truncated strings. Fixes #4046 Co-authored-by: Yong He
