That's a pretty seriously unsafe floating point optimization.

...sh) structures by-value. I haven't investigated at which sizes does that become worse than passing pointers. Maybe a better alternative would be to allocate memory for every local value, and let the mem2reg pass optimize? I hope these kind of questions are appropriate for this list.

...bers llvm.sqrt(x) by definition has undefined behavior and so returning x from llvm.pow(llvm.sqrt(x),2) is acceptable. The same should be true for -inf. Only the result for -0.0 changes from 0.0 to -0.0.

Hi, I wanted to add debug info to my language (compiler written in Scala, outputs .ll files), but I found it really hard to do based on the documentation provided at http://llvm.org/docs/SourceLevelDebugging.html (I looked at the specific doc for LLVM 3.0 though) With LLVM 3.0, DI version 8 (which is documented there) seemed to work, except DW_TAG_auto_variable for which I used version tag 11
