Subject: [GAS/ARM] Fix selected_cpu with default CPU and -mcpu
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=62785b09987359ede74a98fac11343827f7181af;p=binutils-gdb.git

[GAS/ARM] Fix selected_cpu with default CPU and -mcpu

When GAS is compiled with DEFAULT_CPU set and then run with a -mcpu or
-march option, selected_cpu will be set to the default CPU. This means
the -mcpu is ignored which is surprising behavior. This commit instead
sets selected_cpu from the value passed to -mcpu/-march.
