Hi Duncan I am facing a build error about __builtin_iceil when compiled with dragonegg using -ffast-math option. My dragonegg is built with gcc-4.7.0 (I am compiling namd spec benchmark here again). Any idea? g++ -march=bdver2 -save-temps -fplugin=/home/anboyapa/install/bin/dragonegg.so -O2 -march=bdver2 -save-temps -fplugin=/home/anboyapa/install/bin...

Understably,clang cribs > looking at __builtin_iceil. Any idea how to resolve that as well? adding dragonegg support for iceil would solve both problems.

Hi, http://llvm.org/bugs/show_bug.cgi?id=14185 I am stuck on analysis. Does any one have alternate suggestions on debugging llvm?

...-O3 -march=bdver2 -mno-fma -mfma4 -ffp-contract=fast <test.ll> Does clang proceed to optimize the test.ll w.r.t "-O3 -ffp-contract=fast -mno-fma -mfma4" ? (I am not sure if -ffp-contract=fast has any effect there, but I could be wrong though) Also thanks for the immediate fix for __builtin_iceil(). I can see that the issue got resolved. -Anitha -------------- next part -------------- An HTML attachment was scrubbed...

...ny effect there, > but I could be wrong though) I don't know. You can always run it with and without -O3 to see if the output changes. Likewise for the other options. The advantage of using llc is that you have a better idea what is being done. > Also thanks for the immediate fix for __builtin_iceil(). I can see that the > issue got resolved. Thanks for confirming. Ciao, Duncan.
