Thanks. Thus since llvmc -clang just calls clang, my only option is something along the lines of
~> clang foo.c -c -emit-llvm -o foo.bc
~> llc foo.bc -O3 -enable-unsafe-fp-math -o foo.o

, isn't it? Would you know exactly which LLVM options should be used to reproduce -ffast-math -ftrapping-math. Otherwise I'll ask on the LLVM list.
