Extended Description
I've attached a small example with makefile that reproduces the problem. I'm doing this on 10.7 with the latest XCode installed, and llvm-2.9 installed in /usr/local.
Two C++ files are compiled with clang++ -O4, a lib.a archive created of them using llvm-ar, and llvm-ld used to link them. I'm hoping to get LTO from this model of compilation archiving and linking, and perhaps to specialize llvm-ld for some particular linking work. Unfortunately when -native is given to llvm-ld it seems to misread the archive file (?)
llvm-ld without -native completes without reporting an error, although I haven't tried executing the result (I need native code).
the example works fine if I use libtool for the archiving and clang++ for the final link step. I've included commented-out lines in the Makefile to test this case.
Best regards,
