[LLVMdev] Compiling error in 64bit machines

[Anthony Danalis]

The code generated is 32 bit, so your assembler does not like it.  You  
have two options.

a) tell llvm-gcc to call the assembler and linker for 32 bit binaries.

b) tell llvm-gcc to emit llvm code (llvm-gcc --emit-llvm -c -o foo.bc  
foo.c) and then compile the bitcode to 64bit binary with llc (llc - 
march=x86-64 -o foo foo.bc)
