In order to make comdats always explicit in the IR, we decided to make the syntax a bit more compact for the case of a GlobalObject in a comdat with the same name. Just dropping the $name causes problems for @foo = globabl i32 0, comdat $bar = comdat ... and declare void @foo() comdat $bar = comdat ... So the syntax is changed to @g1 = globabl i32 0, comdat($c1) @g2 = globabl i32 0, comdat and declare void @foo() comdat($c1) declare void @foo() comdat llvm-svn: 225302
