Fixes #37189 - [x] Changes comply with the [maintainer guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md). - [x] SHA512s are updated for each updated download. - [x] The "supports" clause reflects platforms that may be fixed by this new version. - [x] Any fixed [CI baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt) entries are removed from that file. - [x] Any patches that are no longer applied are deleted from the port's directory. - [x] The version database is fixed by rerunning `./vcpkg x-add-version --all` and committing the result. - [x] Only one version is added to each modified port's versions file.

Subject: [PATCH 1/2] [SEH] Ignore EH pad check for internal intrinsics
|
|
|
|
Intrinsics like @llvm.seh.scope.begin and @llvm.seh.scope.end which do not throw do not need funclets in catchpads or cleanuppads.
|
|
|
|
Fixes #69428
