This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.

I took example on other pull requests doing the same thing for another target to make the changes. Please feel free to comment if things needs to be added or removed.

Doing ./x.py dist --target thumbv8m.main-none-eabi worked locally so I assume that this will also work on the CI.
It will (I think) however need a new release of alexcrichton/cc-rs to include the pull request alexcrichton/cc-rs#363 @alexcrichton

I hope to do the HardFloat version (thumbv8m.main-none-eabihf) and Baseline (thumbv8m.base-none-eabi) later, as fixes need to be done on compiler-builtins first to support those.

I've published 1.0.27 of cc-rs, should be good to include here!

@alexcrichton Thanks! Is there anything I need to do here to update the cc version used by compiler-builtins? Or will cargo update automatically?

Oh there's a lock file in this repository that'll need to be updated with cargo +nightly update -p cc, and that should do the trick!

@pietroalbini Thanks for the information. The error seems to come from the version of GCC for Baremetal Arm targets (arm-none-eabi-gcc). The dist-various-1 Docker uses Ubuntu 16.04 which has the package gcc-arm-none-eabi version 4.9. However, the support of Armv8-M targets has only been released on the version 5.0 (release note here).
I am on holidays currently and can not work on it, is it possible to remove this pull request from the rollup for now? I will be back in January to work on this issue (if nobody has done it before!).

Replace Arm GCC to a more recent version
The version included in Ubuntu 16.04 repositories in the dist-various-1
docker, Arm GCC version 4.9, does not support the new Armv8-M
architecture.
This commit adds the team-gcc-arm-embedded PPA to get through APT a
newer version of Arm GCC.

I have added a commit which updates the Arm GCC version on the dist-various-1 Docker to solve the error:
arm-none-eabi-gcc: error: unrecognized argument in option '-march=armv8-m.main'
I have tested it trying to execute the Docker image locally (./src/ci/docker/run.sh dist-various-1) but I faced this error:

error[E0514]: found crate `cc` compiled by an incompatible version of rustc

error: aborting due to previous error

I am not sure at this point if this error is due to a cleanup I should do on my machine or if it will happen as well on the CI.

@hug-dev the error on CI is that the lock file needs to be updated (which should be fixable as part of a normal ./x.py build). For the error you gisted above I think that's a bug in our build system, you'll want to probably blow away build or obj and restart the build

@alexcrichton Thanks a lot for the help! I have cleaned build and obj and executed ./x.py build which updated Cargo.lock (new commit pushed). Tried the dist-various-1 docker and worked successfully.

Rollup merge of rust-lang#56954 - hug-dev:armv8m-main-ci, r=alexcrichton
Add dist builder for Armv8-M Mainline

This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.

I took example on other pull requests doing the same thing for another target to make the changes. Please feel free to comment if things needs to be added or removed.

Doing `./x.py dist --target thumbv8m.main-none-eabi` worked locally so I assume that this will also work on the CI.
It will (I think) however need a new release of alexcrichton/cc-rs to include the pull request alexcrichton/cc-rs#363 @alexcrichton

I hope to do the HardFloat version (`thumbv8m.main-none-eabihf`) and Baseline (`thumbv8m.base-none-eabi`) later, as fixes need to be done on compiler-builtins first to support those.

Add dist builder for Armv8-M Mainline

This commit adds the Armv8-M Mainline target in the list of targets that
get their dist components built. It also update the build-manifest so
that this target gets also its dist components uploaded.

I took example on other pull requests doing the same thing for another target to make the changes. Please feel free to comment if things needs to be added or removed.

Doing `./x.py dist --target thumbv8m.main-none-eabi` worked locally so I assume that this will also work on the CI.
It will (I think) however need a new release of alexcrichton/cc-rs to include the pull request alexcrichton/cc-rs#363 @alexcrichton

I hope to do the HardFloat version (`thumbv8m.main-none-eabihf`) and Baseline (`thumbv8m.base-none-eabi`) later, as fixes need to be done on compiler-builtins first to support those.
