* pgsql: Move is_valid_ascii() to ascii.h. @ 2024-01-29 18:09 Nathan Bossart <nathan@postgresql.org> 0 siblings, 0 replies; 3+ messages in thread From: Nathan Bossart @ 2024-01-29 18:09 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org Move is_valid_ascii() to ascii.h. This function requires simd.h, which is a rather large dependency for a widely-used header file like pg_wchar.h. Furthermore, there is a report of a third-party tool that is struggling to use pg_wchar.h due to its dependence on simd.h (presumably because simd.h uses several intrinsics). Moving the function to the much less popular ascii.h resolves these issues for now. This commit is back-patched for the benefit of the aforementioned third-party tool. The simd.h dependency was only added in v16, but we've opted to back-patch to v15 so that is_valid_ascii() lives in the same file for all versions where it exists. This could break existing third-party code that uses the function, but we couldn't find any examples of such code. It should be possible to fix any code that this commit breaks by including ascii.h in the file that uses is_valid_ascii().
