Rafael Espindola	88ea6ab44f	Revert 124633. The linker has been told how to merge available_externally. llvm-svn: 124651	2011-02-01 05:45:26 +00:00
Rafael Espindola	9fa5a67d3d	Set visibility for available_externally globals. This is important for two reasons: * llvm-link would complains about mismatched visibility * If we produce a relocation with an available_externally, it is good to know that it is hidden. llvm-svn: 124633	2011-02-01 00:37:17 +00:00
Douglas Gregor	a700f68828	Reinstate the optimization suppressing available_externally functions at -O0. The only change from the previous patch is that we don't try to generate virtual method thunks for an available_externally function. llvm-svn: 108230	2010-07-13 06:02:28 +00:00
Douglas Gregor	553f3a9b30	Speculatively revert r108156; it appears to be breaking self-host. llvm-svn: 108194	2010-07-12 21:08:32 +00:00
Douglas Gregor	dbb2806a7b	Do not generate LLVM IR for available_externally function bodies at -O0, since we won't be using the definitions for anything anyway. For lib/System/Path.o when built in Debug+Asserts mode, this leads to a 4% improvement in compile time (and suppresses 440 function bodies). <rdar://problem/7987644> llvm-svn: 108156	2010-07-12 17:24:55 +00:00
Douglas Gregor	5dd34744c5	Instantiations subject to an explicit template instantiation declaration have default visibility even under -fvisibility=hidden. Fixes <rdar://problem/8109763>. llvm-svn: 106440	2010-06-21 18:41:26 +00:00
