Make
find_tool
understand VS arch names. This is admittedly partly motivated by the fact that rustc internally uses the namex86
to refer to eitheri586
andi686
where the distinction doesn't matter.I also centralized parsing of the user-provided arch name in one place, rather than being repeated in multiple places. This uncovered a bug in
vs15plus_vc_paths
where we were testing the wrongtarget
variable due to shadowing. I fixed it and renamed the two variablestarget_arch
andtarget_dir
to be clearer.
