--- Comment #5 from Tom de Vries <vries at gcc dot gnu.org> --- (In reply to Tom de Vries from comment #4) > Adding a nop before the .byte fixes this: > + if (debug_info_level >= DINFO_LEVEL_TERSE) > + fputs ("\tnop\n", asm_out_file); Hmm, this'll probably break bootstrap-debug. So I'll need to add the nop unconditionally.
