Subject: gas: drop unused fields from struct emulation
X-Git-Tag: gdb-16-branchpoint~747
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2ced0b79da9839083e7a1f4657b39ba0ae317ab5;p=thirdparty%2Fbinutils-gdb.git

gas: drop unused fields from struct emulation

Neither .match not .bfd_name appear to ever have been used in the last
about 25 years. Purge them.
