bz_status_CONFIRMED "
title="CONFIRMED - llvm-readelf does not accept combined args as GNU readelf does"
href="show_bug.cgi?id=40064">bug 40064</a> for a similar issue in llvm-readelf.
GNU addr2line allows combining of short aliases into a single argument, e.g:
$ addr2line -Ca test.o
is equivalent to
$ addr2line -C -a test.o
As we are adding lots of new short aliases, we should enable grouping behaviour
in this manner. This should just be a case of adding cl::Grouping to the
relevant switches. We need to be careful that we don't break single-dash long
arguments (e.g. -inlining) by doing this.</pre>
