Hi Arpith, That is exactly what it is :). My bad, I thought I copied over the libraries to where LIBRARY_PATH pointing but apparently it was copied to a wrong destination. Thanks a lot.

Yes - all of them. This goes back to the fact that clang/llvm do not support changing the FPENV: https://bugs.ll...

Hi all, I came across an issue caused by the Call-Graph Simplify Pass. Here is a a small repro: ``` define double @foo(double %a1, double %a2, double %a3) #0 { entry: %a_mul = fmul double %a1, %a2 %a_cmp = fcmp ogt double %a3, %a_mul br i1 %a_cmp, label %a.then, label %a.end a.then: %a_div = fdiv double %a_mul, %a3 br label %a.end a.end: %a_factor = phi double [ %a_div, %a.then ],

Are there actually people interested in this? We will continue working anyway but it might not make sense to put it on reviews and announce it on the ML if nobody cares. On 02/24,
