------- Comment #16 from jakub at gcc dot gnu dot org 2008-10-24 15:22 ------- I guess e.g. ia64_expand_prologue could add all those regs that it /* Even if we're not going to generate an epilogue, we still need to save the register so that EH works. */ if (! epilogue_p) emit_insn (gen_prologue_use (XXX_reg)); when epilogue_p as USEs into CALL_INSN_FUNCTION_USAGE of all noreturn calls.
