Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |segher at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I guess this is related to PR84169 r8-6756-gba95aa209678e681dcc86df9ebd0a39501c70187 The code assumes that for split_i2i3 SET_DEST must be a REG or SUBREG of REG, but nothing actually checks this. In the testcase it is a MEM instead.
