We have support for setuo in the architecture but not seto. Sirish -------------- next part -------------- An HTML attachment was scrubbed...

I am having a little trouble with the fcmp one instruction on doubles only. For ordered comparisons, the LLVM manual states that true should be returned iff neither operands is QNAN. ( http://llvm.org/docs/LangRef.html#i_fcmp) If I do fcmp one which includes one or both operands as a NaN, the result is expected to be 0 then. If I run the bitcode with lli (JIT off), no problem. If I use the JIT (lli --force-interpreted=true), then it returns 1. (Converely, fcmp une with the JIT returns 0 instead of the expected 1 ......
