Subject: Invoke the Darwin assembler with -g instead of --gdwarf2.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=591ff15d4a7ae25ea7ac3f00f04f203d3ccec0b7;p=clang

Invoke the Darwin assembler with -g instead of --gdwarf2.

The -g and --gdwarf2 options are currently synonyms to the Darwin assembler.
But clang itself does not recognize --gdwarf2, so if we want to experiment
with using clang, with its integrated assembler, to replace the default
assembler, it is necessary to use -g.  <rdar://problem/10349486>
