1 /* PR target/7042. When reorg.c changed branches into return insns, it
2 completely forgot about any current_function_epilogue_delay_list and
3 dropped those insns. Uncovered on cris-axis-elf, where an insn in an
4 epilogue delay-slot set the return-value register with the testcase
5 below. Derived from ghostscript-6.52 (GPL) by hp@axis.com. */
