Subject: sim: use -Wunused-but-set-parameter
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7f6fa743740e63fa7ecfd35845853ec6814d0500;p=binutils-gdb.git

sim: use -Wunused-but-set-parameter

The code is already clean, so sync this over from gdb warning.m4.
Also shuffle the order of the flags a bit to match the current gdb
warning.m4 code.
