--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Fri Oct 13 07:28:46 2017 New Revision: 253709 URL: https://gcc.gnu.org/viewcvs?rev=253709&root=gcc&view=rev Log: PR target/82498 * fold-const.c (fold_binary_loc) <bit_rotate>: Code cleanups, instead of handling MINUS_EXPR twice (once for each argument), canonicalize operand order and handle just once, use rtype where possible. Handle (A << B) | (A >> (-B & (Z - 1))). * gcc.dg/tree-ssa/pr82498.c: New test. Added: trunk/gcc/testsuite/gcc.dg/tree-ssa/pr82498.c Modified: trunk/gcc/ChangeLog trunk/gcc/fold-const.c trunk/gcc/testsuite/ChangeLog
