Tracking issue for illumos and Solaris x86-64 port work

[am11]

Cut from #4173.

Given below is a high-level list of work items for Solaris x86-64 port:

• Native configurations (Add native configurations for SunOS #34756)

• CoreCLR native components (Port CoreCLR to SunOS #35173)

  • awaiting next release of libunwind https://github.com/libunwind/libunwind/releases/tag/v1.5-rc1 or higher with changes from Illumos fixes libunwind/libunwind#171, for Solaris support.
  • upstream PR was merged, libunwind is updated to 1.5 by @sdmaclea in Libunwind1.5rc2 #36027.

• PAL tests

  • one test is failing is due to paltest_pal_sxs_test1 failed on SmartOS x64 #35362.
  • another one is related to raising thread priority, after lowering it from the same value as a non-root user. this either requires implementation using priocntl(2) directly for SunOS targets, or wait for https://www.illumos.org/issues/4963.

• Libraries native components (Port Native libraries to SunOS #34867)

  • on SmartOS x86_64 with gcc 7x:

    # from runtime repo root
    ./src/libraries/Native/build-native.sh -gcc

• Mono native components (Enable mono cross-build on SunOS-like OS #37560)

  • Full mono (https://github.com/mono/mono) is already available on Solaris, requires some configurations for netcore mono in this repository.

• Installer native components (Define dirent d_type for Solaris based OS #34263)

  • on SmartOS x86_64 with gcc 7x:

    # from runtime repo root
    src/installer/corehost/build.sh -commithash $(git rev-parse HEAD) -gcc \
        -apphostver 5.0.0-dev -hostver 5.0.0-dev -fxrver 5.0.0-dev -policyver 5.0.0-dev

• MSBuild configurations

• CoreCLR managed components (Add configurations for SunOS CoreCLR managed build #36266)

• Libraries managed components

  • Most of the partial classes can be shared with Linux (e.g. by moving it under Unix names) and modifying msbuild configurations.

• Installer managed components

• CoreCLR tests (Fix CoreCLR test build for SunOS #37824)

• Libraries tests

• Mono tests

• Installer tests

• Packaging configurations

• RID (Implement RID for SunOS-derived operating systems #37016)

• Cross compilation on Linux (Add illumos setup to build-rootfs.sh arcade#5584, Add an image to build runtime on illumos dotnet-buildtools-prereqs-docker#324, Add support for illumos cross-compilation #37753)

  • as done for other operating systems, e.g. FreeBSD: https://github.com/dotnet/arcade/blob/3443768/eng/common/cross/build-rootfs.sh#L243.
  • script gets mirrored at https://github.com/dotnet/runtime/blob/master/eng/common/cross/build-rootfs.sh.

• SDK (Add support for SunOS-like platforms sdk#12198)

• CI hook

  • similar to add images to build runtime on FreeBSD dotnet-buildtools-prereqs-docker#277 and add FreeBSD build #34521
  • external (GitHub Actions) CI has set up using the official illumos docker image: https://github.com/am11/runtime/blob/feature/sunos/ci/.github/workflows/main.yml
    • example run: https://github.com/am11/runtime/actions/runs/145127885
    • on tag push, it creates a GitHub release and upload artifacts (files under Shipping directory), e..g. https://github.com/am11/runtime/releases/tag/5.0.0-dev.1
