Hi All,
This fixes a small bug with the warning filtering code, which when a line has
generated a warning and a template decode error (due to the way templates are
resolved) which would not have been emitted and warnings are being suppressed
with -W it would erroneously emit the error.
I have no testcase for this because the only places we generate warnings during
encoding/decoding now is using msr/mrs and system registers. They don't have a
template that would trigger this.
However an upcoming patch series will have tests in it which would expose this bug.
build on native hardware and regtested on
aarch64-none-elf, aarch64-none-elf (32 bit host),
aarch64-none-linux-gnu, aarch64_be-none-linux-gnu
Cross-compiled and regtested on
aarch64-none-linux-gnu, aarch64_be-none-linux-gnu
and no issues.
Ok for master? and for backport to binutils-2.31?
Thanks,
Tamar
