--- Comment #15 from Wilco <wilco at gcc dot gnu.org> --- (In reply to Richard Biener from comment #14) > So I'm quite sure the missed optimization isn't a regression? (can somebody > quickly check GCC 9 whether the testcase is optimized there on ARM?) It fails on both AArch64 and Arm all the way back to GCC6 (oldest compiler I tried). So it's not a regression but this is all target independent so I wouldn't expect this to fail.
