<pre>Although it really shouldn't happen, when both -E and -c are specified to the
compiler, it seems that -E wins (and -c is ignored). The ccc-analyzer tool
should match this behavior, especially since xocdebuild invokes lines like
following:
cc -v -E -dM -arch i386 -x c -c /dev/null
where the -c is extraneous (I think xcodebuild should be fixed as well).
One possible fix to ccc-analyzer would be to change:
if ($Arg =~ /^-(E|MM?)$/) { $Action = 'preprocess'; }
elsif ($Arg eq '-c') { $Action = 'compile'; }
to:
if ($Arg =~ /^-(E|MM?)$/) { $Action = 'preprocess'; }
elsif ($Action ne 'preprocess' && $Arg eq '-c') { $Action = 'compile'; }</pre>
</div>
