Hi Adrian, 

This change looks to have introduced a failure on the clang buildbot for
elf-ppc64.   (This change went in as the same time a previous break was
reverted, so the build went from broken to broken for different reason,
and thus may not have triggered the expected warnings... )

http://lab.llvm.org:8011/builders/clang-ppc64-elf-linux2/builds/3259/steps/check-all

relevant output seems to be:
--
/home/clangbuild2/clang-ppc64-2/llvm.src/tools/clang/test/CodeGenCXX/debug-info-same-line.cpp:58:11: error: expected string not found in input
// CHECK: define i32 @_Z3fooii(i32 %i, i32 %j)
          ^
<stdin>:1:1: note: scanning from here
; ModuleID = '/home/clangbuild2/clang-ppc64-2/llvm.src/tools/clang/test/CodeGenCXX/debug-info-same-line.cpp'
^
<stdin>:46:8: note: possible intended match here
define signext i32 @_Z3fooii(i32 signext %i, i32 signext %j) #0 {
       ^

Thanks, 
-Will
