Speed is not so great, that is why I want to use JIT.<br>I tried building bitcode on windows with llvm-gcc that is provided on llvm home page. Resulting bitcode runs great in interpreter, but it doesn't use JIT. From what I understand from LLVM that it is because of target triple or datalayout. On PC in my case target triple is "i386-mingw32", but LLVM JIT for ARM expects something that starts with "armv" or "thumb". Also datalayout differs a lot. If I understand correctly that is because bitcode actually contains some of platform specific optimizations (like integer endianness), so I can't simply change target triple string and everything will run.<br><br>What I am now doing, is - I am trying to build gcc from gcc-4.2-llvm-2.5 sources with following configure line in cygwin shell:<br><br>../llvm-gcc4.2-2.4.source/configure --enable-languages=c,c++ --enable-checking --enable-llvm=$PWD/../llvm-objects --disable-bootstrap --disable-multilib --disable-nls --target=arm-eabi<br><br>My undertanding is that this will produce llvm-gcc compiler that will output LLVM bitcode with target triple that starts with "arm", so LLVM will use JIT on it.<br><br>Currently I am getting compile problems when running make (see below).<br>Has anyone done something similar and can explain what I am doing wrong, or how should it be done in some other way to get JIT compiler running on ARM?<br><br><br>make[2]: Entering
