Hi ScaffCC developers,

based on LLVM release_31 before the commit https://github.com/epiqc/ScaffCC/commit/871865b5409d163c0a8f95e206d845b889c8f72a

Before FlattenModule PASS, sha1.n12812.ll is 222+K, but after FlattenModule, sha1.n12812.inlined.ll is 6837+K! then gen-gasm failed to transform such HUGE LLVM IR.

@eddieschoute Please try @ajavadia latest commit https://github.com/epiqc/ScaffCC/commit/871865b5409d163c0a8f95e206d845b889c8f72a it might be able to work for SHA-1 algorithm https://github.com/epiqc/ScaffCC/issues/7#issuecomment-348235689
