Hi, Gentle ping: https://gcc.gnu.org/pipermail/gcc-patches/2022-February/590959.html This patch is to fix one regressed test case, I guess it still can be considered for stage 4. BR, Kewen > on 2022/2/28 1:37 PM, Kewen.Lin via Gcc-patches wrote: >> Hi, >> >> As PR103196 shows, p9-vec-length-fu

Hi, As PR103196 shows, p9-vec-length-full-7.c needs to be adjusted as the complete unrolling can happen on some of its loops. This patch is to use pragma "GCC unroll 0" to disable all possible loop unrollings. Hope it can help the case not that fragile. There are some other p9-vec-length* cases,
