Subject: Update printing of optional operands during disassembly.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bda678b9e5e4a343a9bb2b0fd20cf52035bad78e;p=binutils-gdb.git

Update printing of optional operands during disassembly.

opcodes/
	* ppc-dis.c (skip_optional_operands): Change return type and returns.
	(print_insn_powerpc) <skip_optional>: Change type.
	Call skip_optional_operands if we have not skipped any operands.
gas/
	* testsuite/gas/ppc/476.d: Update expected output.
	* testsuite/gas/ppc/power6.d: Likewise.
