Subject: [ELF] Dont add local symbols for dynamic lookup.
X-Git-Tag: llvmorg-3.7.0-rc1~8683
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14726cd11b8727a569917475bbffa4b09f94148c;p=platform%2Fupstream%2Fllvm.git

[ELF] Dont add local symbols for dynamic lookup.

Unable to add a unit test for this, as there is only one local undefined
symbol in regular shared libraries without a name.
