Answer 1

Make sure your llvm-gcc's version match the version of LLVM you installed - the binary IR format changes quite fast and is not backward compatible across several version.

Alternatively, you might try to emit text representation of LLVM IR out of llvm-gcc and assemble it through llvm-as.

Something like this:

llvm-gcc -emit-llvm -S foo.c -o foo.ll
llvm-as foo.ll -o foo.bc
llc foo.ll -o foo.S

etc.
