similar to: [LLVMdev] Dragonegg build broken?

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

Yest. thanks. I just resolved this error by installing MPFR, MPC and GMP(by the way, these are not listed as prerequisites in the website.). But other errors come: /home/xxx/llvm/tools/dragonegg/src/TypeConversion.cpp: In function > ‘llvm::FunctionType* ConvertArgListToFnType(tree_node*, > llvm::ArrayRef<tree_node*>, tree_node*, bool, llvm::CallingConv::ID&, >

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

Can you send the binaries compiled with and without the integrated assembler. Maybe I can figure out the encoding problem. I've been unsuccessful figuring it out myself so far.

Hi, When I tried to compile Dragonegg using the SVN trunk code, I encountered failure with error message: In file included from > /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5.2/plugin/include/rtl.h:28:0, > from /home/xxx/llvm/dragonegg/src/Convert.cpp:63: > /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5.2/plugin/include/real.h:27:18: > fatal error: mpfr.h: No such

I'm still slightly confused. Is the error now fixed or is there still a bug in LLVM's integrated assembler?

I will look into it immediately. Apologies for the late e-mail. I ran out of time devoted for this PR and moved on. Coincidentally, only today I came back to this PR for further

Hi Anitha, Thanks for your answer but -mcpu=cortex-a9 -mattr=+vfp4 doesn' t enable fused mac generation for me. I would like just to understand why -mtriple=armv7-eabi enables it while -mcpu=cortex-a9 seems to disable it ?

Hi Bastien, Weird gcc is generating fma for my platform STEricsson Novathor with Linaro, code works. It also works when I use LLVM to generate fma (using llc -mtriple=armv7-eabi). Maybe someone from ARM can answer the question ?

AFAIK A9 doesn't have VFPv4 or AdvSIMDv2, so it doesn't have VFMA. I don't know what LLVM does, but it shouldn't emit VFMA when you target A9. VMLA isn't a fused multiply-add, it's a multiply followed by an add and has different latency as well as precision.
