Lu <[email protected]> Date: Mon Jul 13 09:12:13 2026 +0800 x86-64: Add missing SSE and AVX zero-extend patterns 1. Add round_zext and round_saeonly_zext to subst.md. 2. Use them to add missing SSE and AVX zero-extend patterns. 3. Add tests to check for newly added SSE and AVX zero-extend patterns. gcc/ PR target/126231 * config/i386/i386.md (*fix_trunc<mode>si_sse_zext): New. * config/i386/sse.md (*avx512fp16_vcvtsh2<sseintconvertsignprefix>si<round_zext_name>): Likewise.
