Hi Eduardo,

(In reply to Eduardo Luis Marcovecchio from comment #12)
 Please, no news on this subject yet?  


Sorry for dropping the ball on this one.

Unfortunately I do not have an easy way of testing COFF/PE binaries at the
moment, so I am going to ask for your help.  I have checked in Kai's patch to
the mainline binutils sources on an experimental basis.  Please could you try
it out and if/when you encounter problems, please could you file them here.  A
testcase to reproduce the problem would be very helpful, as would the output
from the linkers --print-gc-sections option.

Cheers
  Nick

I would say Qt and Boost could also be used as a testbed. Qt doesn't have a
test suite though, but I guess compiling the examples might be a first
indication. Boost has a test suite.

(Just FYI - I am going to be on vacation next week, so I will not be able to
respond to bug reports until the week after ...)

Thanks a lot, Nick!

I will do that as soon as possible, probably recompiling wxWidgets with
-ffunction-sections and -fdata-sections, then linking a simple app with -Wl and
--gc-sections enabled.

If anyone has suggestions on other libs to test, I will be glad to test with
them too.

Eduardo
