[LLVMdev] Distribution in assembler format

[Samuel Crow]

Hello Russell,

Major pitfall #1:
LLVM-GCC does certain optimizations even if all of the optimizations are turned off.  These include endian-specific optimizations so to use LLVM as a cross-architecture bitcode, you'll need to wait until Clang supports C++ fully or just stick to C programs for now.

I've been looking forward to the day that LLVM can be used for cross-architecture development, myself.

Thanks for asking,

--Sam
