This PR extends the CI Build Rules to eliminate more unnecessary builds. We use the Board Label for PRs:
- Previously: "Arch: arm" will build only `arm-01` to `arm-14`
- Now: "Board: arm" will also build `arm-01` to `arm-14`
- This applies only to Simple PRs: One Arch Label + One Board Label + One Size Label, like "Arch: arm, Board: arm, Size: L"
- If Arch Label and Board Label are both present: They must be the same. Otherwise All Targets shall be built.
- Works with Arm32, Arm64, RISC-V, Simulator, x86_64 and Xtensa
The updated code is explained here: https://github.com/apache/nuttx/issues/13775
This PR continues to enhance the CI Workflow, to skip the unnecessary NuttX Builds. The changes in this PR will not take effect until the next PR, which will switch `build.yml` to use the rules in this PR.
In this PR, we refactor the CI Build Rules into a separate Reusable Workflow `arch.yml`. The original rules were migrated to `arch.yml`:
- We target only the Simple PRs: One Arch Label + One Size Label (e.g. "Arch: risc-v, Size: XS")
- For "Arch: risc-v": Build `risc-v-01`, `risc-v-02`
- For "Arch: xtensa": Build `xtensa-01`, `xtensa-02`
- The above rules apply when the PR is Created or Modified
- When the PR is Merged: All targets shall be built
New and Updated Rules:
- For "Arch: arm": Build `arm-01`, `arm-02`, ...
- For "Arch: arm64": Build `other`
- For "Arch: simulator": Build `sim-01`, `sim-02`
- For "Arch: x86_64": Build `other`
- For Simple PRs (One Arch Label + One Size Label): Skip the macOS and Windows builds (`macos`, `macos/sim-*`, `msys2`) since these builds are costly and slow
- Except for "Arch: Simulator", which will enable the macOS Builds for `sim-01` and `sim-02`
- If GitHub CLI Fails: Build all targets
