[PATCH] D35081: [ThinLTO] Allow multiple summary entries.

yunlian added a comment.

This error happens when I try to triage a thinLTO failure on ARM.

Initially I got some error like 
Instruction does not dominate all uses!

  %205 = bitcast i1 (%"class.blink::LayoutObject"*)** %194 to i8*, !dbg !51180
  %200 = getelementptr i8, i8* %205, i32 ptrtoint (i8* @__typeid__ZTSN5blink12LayoutObjectE_100_byte to i32), !dbg !51170

LLVM ERROR: Broken function found, compilation aborted!
clang-5.0: error: linker command failed with exit code 1 (use -v to see invocation)

I then used distributed thinLTO to try to find a reduced test case.
I use -Wl,-plugin-opt,thinlto-index-only=file to get the index file for each bite code and I
run
$cmd -fthinlto-index=${obj}.thinlto.bc -x ir ${obj} -o a.o -c

to get the error shown in this change.
