`/tmp` doesn't exist on Windows. If you really need to check the full path,
you'll have to do something like adding
`! RUN: mkdir %t`
before the first RUN line, and
` ! RUN: env TMPDIR=%t TEMP=%t TMP=%t %flang ...`
on every run line, although I couldn't quite make this work correctly when I
quickly looked.
Alternatively, just don't check the directory, I don't see any other tests in
clang that check the directory that the temporary object is in.
Additionally, the driver will translate `-lm` and `-lhappy` to `m.lib` and
`happy.lib` for the link line on Windows. So these should be something like
"{{(-l)?m(\.lib)?}}" "{{(-l)?happy(\.lib)?}}" to work on Windows.
libomp is linked differently on Windows, and doesn't end up last with this
change. I'm not sure how much that matters; perhaps limit that part of the test
to Linux only (e.g. with -target=aarch64-unknown-linux-gnu; since you're using
-### already it doesn't matter if that target is actually compiled or not)
