## Description
We started seeing rate-limit `429` errors when cloning LLVM (as seen in
e.g. [this failed
run](https://github.com/paritytech/revive/actions/runs/28924583524/job/85809154518)
and [this failed
run](https://github.com/paritytech/revive/actions/runs/28926259175/job/85821336465?pr=564)).
`llvm/llvm-project` now seems to be heavily rate-limited by GitHub.
(Authenticating the clone did not seem to have much effect.)
Even though our resolc build steps only do a treeless clone, all build
steps still did the same clone.
### Changes
* I've instead introduced a `.llvm-version` file that the `get-llvm`
action reads from, eliminating the network request all together.
* `.llvm-version` is meant to be kept in sync with the LLVM submodule
version we use. This is enforced by:
* Introduced a `check-llvm-version.yml` workflow
* Runs once to check that the recorded version in `.llvm-version`
coincides with the version detected from the submodule.
* The submodule version detection *does* perform a network request as
before, but this is only run once now (when relevant files change),
rather than for all our resolc build jobs.
* Since the differential test jobs require checking out our
revive-differential-tests (rdt) submodule, those checkout steps cloned
not only rdt, but also LLVM. I've updated this to not clone LLVM at all.
## Description
Improves overall time spent for our CI checks to complete. For cache
hits, total time decreases from ~70min to ~29min.

## Changes
| Change | Before | Now |
|---|---|---|
| **Per-target build sub-workflows** | <ul><li>Getting a reusable build
depended on all builds completing.</li><li>Even if e.g. a macOS build is
cached, the waiting workflow with macOS runners could be queued for a
long time just to get the status and cache of the other workflow, since
macOS runners are more scarce than e.g. Ubuntu.</li></ul> |
<ul><li>Split umbrella `reusable-build.yml` into
`reusable-build-{linux,macos,windows,wasm}.yml`.</li><li>Consumers can
wait on a specific target and start earlier instead of blocking on the
whole matrix.</li><li>E.g. E2E and the compile-and-hash matrix start
earlier (gate only on the targets needed).</li></ul> |
| **Bottleneck macOS Intel only running on `main`** | macOS Intel
runners are 2-3× slower than macOS ARM for the contract compilation
tests. Ran on each PR, being the bottleneck. | This build is now
excluded from the matrix for PR runs, and only included for pushes to
`main`. |
| **E2E tests use higher concurrency** | `run-e2e-tests` duration:
~43min.</li></ul> | <ul><li>Uses higher number of concurrent tasks, made
possible by retester flakiness fix.</li><li>`run-e2e-tests` duration:
~16min.</li></ul> |
| **Faster LLVM downloads** | Building resolc took ~8-13min (~16 min on
macOS intel). | `get-llvm/action.yml` uses more efficient version
detection. Building resolc now takes ~2min (~4-7 min on macOS intel). |
| **Wasm tests use cached artifacts** | `test-wasm.yml` ran its own
duplicate build. | `test-wasm.yml` uses the reusable Wasm build. |
| **Skip unnecessary polkadot-sdk package** | For E2E tests,
`polkadot-omni-node` was unconditionally downloaded (~3-4min). | Only
`pallet-revive-eth-rpc` and `revive-dev-node` are downloaded from the
cache. |
| **Cache `report-processor`** | Only `retester` was cached. |
`report-processor` is cached for the compilations and export hashes
jobs. |
| **Hardhat unblocked from differential tests** | Started after the
differential tests succeeded in order to reuse the Linux build. | Starts
as soon as the required `test` job succeeds, using the reusable Linux
build. |
| **Conditionally skip workflows** | <ul><li>Some workflows
conditionally skipped for md-only changes.</li><li>Tooling-only changes
also ran e.g. `test-wasm.yml` and `differential-tests.yml`.</ul></li> |
<ul><li>Most workflows are skipped for doc-only
updates.</li><li>Tooling-only updates trigger only the respective
tooling test (Hardhat), apart from the required `test`
job.</li><li>Differential tests are skipped for js-only
updates.</li></ul> |
| **Miscellaneous** | <ul><li>Used actions running on soon-deprecated
Node 20.</li><li>Difficult to debug Playwright `test-wasm`
failures.</li></ul> | <ul><li>Upgraded actions that used Node
20.</li><li>Added Playwright debug traces uploaded on `test-wasm`
failures.</li></ul> |
## Resolved Issues
Closes#533
- Support solc v0.8.35
- The new `erc7201` is comptime (already translated to a constant in
Yul)
Didn't spot any relevant breakage or addition in the release notes so
should be no-brainer.

## Description
Applies LLVM patches that have not been backported to the major version
used in our submodule:
* [LLVM PR #163679](https://github.com/llvm/llvm-project/pull/163679)
* *"[RISCV] Allow large div peephole optimization for minsize"*
* Fixes peephole optimization of large integers when `minsize` function
attribute is set.
* (Our revive codebase used a workaround that can be removed once this
500 PR is merged and we publish a new LLVM release.)
* [LLVM PR #190219](https://github.com/llvm/llvm-project/pull/190219)
* *"[TargetLowering] Speculative fix for a non-determinism issue between
different compilers"*
* Operand ordering of `mul i256` were different depending on the target
ABI when building LLVM, producing different RISC-V and PVM bytecode for
our Windows vs macOS/linux builds.
* The bytecode divergence (yet functionally equivalent) affected
Solidity contracts containing a value [multiplied by
itself](https://github.com/llvm/llvm-project/issues/190148) (e.g. via
explicit squaring or exponentiation), manifesting primarily when using
optimization level `-O0`.
Emscripten 4.0.12 introduced breaking change by changing module factory
to always return promise even if `WASM_ASYNC_COMPILATION=0`. To overcome this, build emscripten compiler without MODULARIZE with custom export of `createRevive`.
As a drive-by fix, the get-llvm action now ignores LLVM releases marked
as pre-release.

This change is essential first step to unblock gracefully enable LLVM 21
in revive compiler as current action blindly fetched latest LLVM binary
from the list of releases on our page.
The change queries release version from the submodule and uses it. Next
step: build LLVM 21 release binary
Next next step: switch revive compile to LLVM 21 after all issues are
fixed
- Add support for solc `v0.8.30`. No changes in YUL or the binary
interface.
- Fix a semver bug in the NPM packages to correctly align their solc
dependencies with our last supported version.

No observable changes w.r.t. YUL compilation.
- Mark solc v0.8.29 as the latest supported version
- Add integration test for solc v0.8.29 specific feature
- Use the latest version on CI
- Drive-by fix linter complaints and a two types in the CI yaml files

This PR changes the CI build scripts to also build LLVM for windows.
**It doesn't build `revive` itself for windows**. This will come in a
follow up. But once we have a LLVM binary release the turn around time
will be much quicker for experimenting with the revive windows build.
I manually uploaded the release those changes produce
[here](https://github.com/paritytech/revive-alex-workflowtest/releases/tag/llvm-18.1.8-revive.22f3ceb).
This enables this PR's CI to find the proper release. This is necessary
because I am also making changes to the folder structure and artifact
naming that the other CI jobs are depending on.
Releases generated from this branch can be inspected here:
https://github.com/paritytech/revive-alex-workflowtest/releases/tag/v0.1.0-dev.12
Summary of changes:
- Change `llvm-builder` to use MSVC toolchain on windows
- Fix `llvm-builder` to work with `.exe` files
- Unify the llvm release jobs into a single one. This removed a lot of
copy pasted code and also speeds up the build by giving each their own
runner.
- Use the LLVM target triple to name the binary releases instead of an
ad-hoc naming convention
- Remove the nested folder hierarchy inside the llvm release. Its just
now a single folder `llvm-<target>` that contains the toolchain.
- Give jobs and workflows consistent names
- Replace all runners bei their `*-latest` counterpart
- Only use `parity-large` to build llvm now. All other jobs use github
runners
- llvm artifacts search, download and extract now in `get-llvm` action
- `get-emsdk` action - clone, install, activate emsdk, so we don't need
to build `revive-builder` for this
- switch workflows to new actions
- `concurrency` for remaining workflows (cancel run if new run is
triggered)
- `target_commitish` for main release, fixes release commit
- Run release workflow in PR without creating a release if PR is labeled
with `release-test`
