Hi,
This straightforward patch fixes the following warnings I see when building
for AArch64.
gcc/config/aarch64/aarch64.c:6385:7: warning: unused variable âregâ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6385:12: warning: unused variable âmemâ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6385:17: warning: unused variable âaddrâ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6386:7: warning: unused variable âloadâ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6669:17: warning: variable âmod_sâ set but not used [-Wunused-but-set-variable]
Regression tested on aarch64-none-elf with no regressions and checked
to ensure that the warnings go away.
OK to commit?
Thanks,
James Greenhalgh
