Don't verify inputs to the Linker if ODR merging. This fixes pr28072. The point, as Duncan pointed out, is that the file is already partially linked by just reading it. Long term I think the solution is to make metadata owned by the module and then the linker will lazily read it and be in charge of all the linking. Running a verifier in each input will defeat the lazy loading, but will be legal. Right now we are at the unfortunate position that to support odr merging we cannot verify the inputs, which mildly annoying (see test update). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@274148 91177308-0d34-0410-b5e6-96231b3b80d8 2016-06-29 18:31:48 +00:00			`; RUN: not llvm-link -disable-debug-info-type-map -o /dev/null %s 2>&1 \| FileCheck %s`
llvm-link: Verify input modules Otherwise, broken input modules can cause assertions. I've updated two of the testcases that started failing (modules that had `Require` flags but didn't meet their own requirements), but Rafael and I decided that test/Linker/2011-08-22-ResolveAlias.ll should just be deleted outright -- it's a leftover of the way llvm-gcc used to implement weakref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233229 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-25 23:22:10 +00:00
tools: Unify how verifyModule() is called Unify the error messages for the various tools when `verifyModule()` fails on an input module. The "brave new way" is: lltool: path/to/input.ll: error: input module is broken! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233667 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-31 03:07:23 +00:00			`; CHECK: broken.ll: error: input module is broken!`
