Subject: Show INSN_UIDs in compact mode
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7574cfd44c1f73e2083c525e1a79ab716f7a994b;p=gcc.git

Show INSN_UIDs in compact mode

gcc/ChangeLog:
	* print-rtl.c (rtx_writer::print_rtx_operand_code_u): Print
	INSN_UIDs for all insns in compact mode.
	(rtx_writer::print_rtx): Likewise.
	* print-rtl.h (rtx_writer::flag_compact): Update comment.
	* rtl-tests.c (selftest::test_dumping_insns): Update expected
	output to include INSN_UID.
	(selftest::test_uncond_jump): Likewise.
