--- Comment #4 from ktkachov at gcc dot gnu.org --- hmmm... now I'm getting a different ICE: internal compiler error: in arm_dbx_register_number, at config/arm/arm.c:25834 a gcc_unreachable () is reached. If I print out the regno argument to arm_dbx_register_number, it's 272 which seem to me like it could be reg number in DWARF numbering?
