--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kewen Lin <li...@gcc.gnu.org>: https://gcc.gnu.org/g:f33fc0775706e4db80d584c477608e28f4da0a6f commit r13-6870-gf33fc0775706e4db80d584c477608e28f4da0a6f Author: Kewen Lin <li...@linux.ibm.com> Date: Sun Mar 26 21:42:23 2023 -0500 rs6000: Ensure vec_sld shift count in allowable range [PR109082] As PR109082 shows, some uses of vec_sld in emmintrin.h don't strictly guarantee the given shift count is in the range 0-15 (inclusive). This patch is to make the argument range constraint honored for those uses. PR target/109082 gcc/ChangeLog: * config/rs6000/emmintrin.h (_mm_bslli_si128): Check __N is not less than zero when calling vec_sld. (_mm_bsrli_si128): Return __A if __N is zero, check __N is bigger than zero when calling vec_sld. (_mm_slli_si128): Return __A if _imm5 is zero, check _imm5 is bigger than zero when calling vec_sld. gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr109082.c: New test.
