Subject: gas: Record file name in macro locations
X-Git-Tag: gdb-17-branchpoint~265
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9e5fdac9ac81c8bc383f4314388c2c830f1e575c;p=thirdparty%2Fbinutils-gdb.git

gas: Record file name in macro locations

This allows the correct file name to be used when emitting messages for
lines within a macro.  The line numbers were already set and displayed
correctly, which resulted in mismatched file names and line numbers.
