GCC maintianers:
In the process of fixing the powerpc/vec-replace-word-runnable.c test I found there is an existing issue with function find_instance in rs6000- c.cc. Per the review comments from Kewen in https://gcc.gnu.org/pipermail/gcc-patches/2023-July/624401.html The fix for function find_instance was put into a separate patch followed by a patch for the vec-replace-word-runnable.c test fixes. The two patches have been tested on Power 10 LE with no regression failures. Carl
