I would squash your commits and fix the warning ^. It might be nice to include a commit description and maybe a comment why only cross builds are supported

[tristan957]

you'll also want to add a release snippet

Hi, I don't understand why checks failed on macos-clang and gccx64ninja. I see no relationship between thoses tests and my modifications... Your help is welcome :-)

[eli-schwartz]

I think those are both flaky tests, so I'm rerunning them to check.

[gall1]

Still a flaky tests ? One more run needed ?

Hi, @gall1

I'm curious how you make IAR deal with assembly code with meson.

I have tried iccarm compiler with meson before but failed, and I find iccARCH can't compile assembly code directly, only iasmARCH can deal with assembly code.

Thanks.
