[llvm-dev] Codegen difference between Asserts and No-Asserts mode

[Hal Finkel via llvm-dev]

Hi Sumanth,

I don't know to what you're referring, but the output from Release vs. Release+Asserts should be identical. There might be differences in the IR value names, but if that is affecting the final result, that's a bug.
