[ruby-core:121699] [Ruby Feature#21277] Windows ARM support

From: "hsbt (Hiroshi SHIBATA) via ruby-core" <ruby-core@...>
Date: 2025-04-21 03:47:53 UTC
List: ruby-core #121699
Issue #21277 has been reported by hsbt (Hiroshi SHIBATA).

----------------------------------------
Feature #21277: Windows ARM support
https://bugs.ruby-lang.org/issues/21277

* Author: hsbt (Hiroshi SHIBATA)
* Status: Open
* Assignee: hsbt (Hiroshi SHIBATA)
----------------------------------------
I added the new CI job for Windows ARM support.

* https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/
* https://github.com/ruby/ruby/pull/13118

We could build Ruby with Windows ARM platform. But `nmake check` is not working yet. I'm tracking that issues on this ticket.

## Can't generate `revision.h`

`windows-11-arm` runner couldn't generate `revision.h` with `ruby tool/file2lastrev.rb --revision.h --output=revision.h`. I tried that with git provided by `scoop`. But that is also not working.

I confirmed to work `git rev-parse HEAD` directly with `pwsh` of GitHub Actions. But `tool/file2lastrev.rb` returns the followings:

```
Run ruby tool/file2lastrev.rb --revision.h --output=revision.h
  
file2lastrev.rb: git rev-parse failed
  fatal: unable to access 'NUL': Invalid argument
```

## `nmake check` is not working

https://github.com/ruby/ruby/actions/runs/14564201209/job/40851166866

```
running file: C:/a/ruby/ruby/src/test/rubygems/test_gem_resolver_index_set.rb
  A test worker crashed. It might be an interpreter bug or
  a bug in test/unit/parallel.rb. Try again without the -j
  option.
```

https://github.com/ruby/ruby/actions/runs/14564667517/job/40852193517

```
  NMAKE : fatal error U1077: '@  .\ruby.exe -I../src/lib -I".ext/arm64-mswin64_140" -I. "../src/tool/runruby.rb" --extout=".ext"  -- --disable-gems -r./arm64-mswin64_140-fake -r../src/tool/lib/_tmpdir  ../src/spec/mspec/bin/mspec run -B ../src/spec/default.mspec  ' : return code '0xc0000005'
  Stop.
```

They may be caused by Visual Studio 2022 issue same as #21255.
