Hi Jeff,
You probably know the capabilities of COFF/PE better than I, so the
patch itself is fine.
Thanks - committed.
Is there any way that test can be shoved into our dejagnu testing
harness? I think we've got support somewhere for tests which require
multiple input files.
dg-additional-sources is the command that you are thinking about.
The attached patch adds the test derived from the BZ. There is one
small problem - I could not find a way to stop the additional source
file from being compiled as a test on its own. When I investigated
however it seems that is a common problem for all tests that use
additional source files, so I do not think that it is a big issue.
Tested with no regressions on an x86_64-pc-linux-gnu toolchain.
OK to apply ?
Cheers
Nick
