In
rustc_codegen_gcc
, we run theASM
test suite. The problem is that, if a too recent version of thellvm-filecheck
binary is provided, an extra argument needs to be passed and the to detect this version, it currently only expects a--llvm-version
argument. With this, the version can be determined directly from thellvm-filecheck
binary.r? @Amanieu
