Wed, 23 Mar 2016 21:16:33 +0000

Fix logic for which symbols to keep with comdats.If a comdat is dropped, all symbols in it are dropped.If a comdat is kept, the symbols survive to pass regular symbolresolution.With this patch we do that for all global symbols.The added test is a copy of test/tools/gold/X86/comdat.ll that we nowpass.llvm-svn: 264192 List of files: /llvm-project-15.0.7/llvm/test/Linker/constructor-comdat.ll

83a362cd - Change the .ll syntax for comdats and add a syntactic sugar.

Tue, 06 Jan 2015 22:55:16 +0000

Change the .ll syntax for comdats and add a syntactic sugar.In order to make comdats always explicit in the IR, we decided to makethe syntax a bit more compact for the case of a GlobalObject in acomdat with the same name.Just dropping the $name causes problems for@foo = globabl i32 0, comdat$bar = comdat ...anddeclare void @foo() comdat$bar = comdat ...So the syntax is changed to@g1 = globabl i32 0, comdat($c1)@g2 = globabl i32 0, comdatanddeclare void @foo() comdat($c1)declare void @foo() comdatllvm-svn: 225302 List of files: /llvm-project-15.0.7/llvm/test/Linker/constructor-comdat.ll
