Fix use of uninitialized variable. Fixes linking bitcode files that use the new style comdats for constructors with ones that don't. llvm-svn: 215364

; RUN: llvm-link %s %p/Inputs/constructor-comdat.ll -S -o - 2>&1 | FileCheck %s
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 symbol resolution. 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 now pass. llvm-svn: 264192

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