Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290 2009-09-09 01:54:48 +02:00			`; RUN: llc < %s \| grep weak \| count 3`
Drop bunch of half-working stuff in the ext_weak linkage support. Now we're using one gross, but quite robust hack :) (previous ones did not work, for example, when ext_weak symbol was used deep inside constant expression in the initializer). The proper fix of this problem will require some quite huge asmprinter changes and that's why was postponed. This fixes PR3629 by the way :) llvm-svn: 65230 2009-02-21 12:53:32 +01:00			`; PR3629`
