[llvm-commits] bug fix to get lto-bugpoint to compile

[Erick Tryzelaar]

Good morning. I was trying to build lto-bugpoint this morning, and it
seems that it was missed in revision 55092 changing the argument types
for addPassesToEmitFile. This patch copies what happens in llc when
calling addPassesToEmitFile, so hopefully it's alright. I'm not sure
how to test this to confirm it works though:
