--- Comment #10 from ktkachov at gcc dot gnu.org --- For the testcase, having it in gcc.target/aarch64/sve as /* { dg-options "-O2" } */ #include <arm_sve.h> svbool_t foo (svint8_t a, svint8_t b, svbool_t c) { svbool_t d = svcmplt_s8 (svptrue_pat_b8 (SV_ALL), a, b); return svsel_b (d, c, d); } would be fine.
