Just verified that Target.cpp and x86_builtins do not have iceil support. I have this tricky situation - I use dragonegg generated LLVM IR as input to clang for some analysis (well it is clang++ actually). Understably,clang cribs looking at __builtin_iceil.

Hello, just trying to use the dragonegg plugin with gcc on my project. Unfortunately I get an /usr/local/lib/gcc/x86_64-unknown-linux-gnu/4.5.2/include/ia32intrin.h:170:35: error: unsupported target builtin ‘__builtin_ia32_bsrdi’ used error. I use (and need) the "bsr" (bit scan reverse) instruction. So it seems it isn't implemented (yet). Can I safely use gcc inline assembly

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/dragonegg.so -mno-fma -mfma4 -ffast-math
