Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- E.g. the i386 backend usually uses force_reg in this case. If the operand is a REG, it does nothing, if it is a SUBREG, it is forced into a temporary and then the subreg in the pattern will DTRT.
