Subject: Ignore llvm specific symbols in the LTOModule.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e97c25bad489d151324d48a900ad7e2779afe53e;p=oota-llvm.git

Ignore llvm specific symbols in the LTOModule.

These are the llvm.* globals and functions.

I don't think it is possible to test this directly since llvm-lto is not
a full linker and will not report duplicated symbols, but this fixes
bootstrap with gold and lto enabled.
