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.

The `--bin` CLI flag was not producing bytecode because the
`outputSelection` was not updated to explicitly requested it.

# Description
Compilation times for resolc were significantly slower than solc when:
* Multiple files were included in the JSON input file via
`--standard-json`
* And none of the files requested code generation
* (If only a subset of files requested code generation, both resolc and
solc were very slow)
Reason:
* Resolc unconditionally generated bytecode for all contracts, even if
not requested.
* When compiling to PolkaVM bytecode, we need to pass additional flags
(e.g. `irOptimized`) to solc. If these flags were not explicitly
requested, resolc also added these to the requested output since PolkaVM
bytecode was always generated.
## Breaking Changes
The following changes are breaking, but fix the semantics to match its
intended behavior:
* Compiling with `--standard-json` now compiles to PolkaVM bytecode
***only*** for the contracts explicitly requested in the
`outputSelection`.
* Compiling with `--standard-json` now outputs ***only*** the explicitly
requested output (e.g. `evm.assembly`, `evm.bytecode`, `ast`, etc.).
```jsonc
// Example:
{
"settings": {
// ...
"outputSelection": {
"src/common/GasService.sol": {
// Contracts in this file will generate bytecode.
// Only these fields of the JSON output selection will be in the `contracts` output.
"*": ["abi", "evm.methodIdentifiers", "metadata", "evm.bytecode"],
// Only this field of the JSON output selection will be in the `sources` output.
"": ["ast"]
},
"src/common/Gateway.sol": {
// No contracts in this file will generate bytecode.
"*": ["abi", "evm.methodIdentifiers", "metadata"],
// No `ast` will be in the `sources` output (only the automatically added `id`,
// similar to solc as this is not a configurable output selection).
"": []
},
}
}
}
```
## Performance Improvements
When e.g. the standard JSON input file includes multiple files and
requests output for every contract as per this setting:
```jsonc
{
"settings": {
// ...
"optimizer": { "enabled": true, "runs": 1 },
"viaIR": true,
"outputSelection": {
"src/common/GasService.sol": {
"*": ["abi", "evm.methodIdentifiers", "metadata", "evm.bytecode"],
},
// Rest of files..
}
}
}
```
The differences in compilation times depending on whether `evm.bytecode`
is selected in every file, one file, or no files can be seen below:
| Solc Optimizer (runs=1) | ViaIR | Request `abi`,
`evm.methodIdentifiers`, `metadata` | Request `evm.bytecode` | resolc
before | resolc after | solc v0.8.33 |
|:-----------------------:|:-----:|:---------:|:---------:|:-------------:|:------------:|:----------:|
| ✅ | ✅ | All files | All files | `~14.5s` | `~14.5s` | `~13.5s` |
| ✅ | ✅ | All files | One file | `~14.5s` | `~450ms` | `~13.5s` |
| ✅ | ✅ | All files | No files | `~14.5s` | `~390ms` | `~350ms` |
**Observations:**
* `resolc before` is roughly the same no matter the request
* This is due to unconditionally generating bytecode
* When not requesting bytecode for any contracts:
* `resolc after` now compiles in ~390ms (vs ~14.5s), similar to `solc`
* Neither `solc` nor `resolc after` generates bytecode when none of the
contracts request it
* When requesting bytecode for all contracts in _only one_ file:
* `resolc after` now compiles in ~450ms (vs ~14.5s)
* `solc` still compiles in the same time as when requesting bytecode for
all contracts in all files
* This is something they have tried to improve (see
[Solidity#15373](https://github.com/argotorg/solidity/issues/15373) and
[Solidity#15615](https://github.com/argotorg/solidity/issues/15615)),
and the intended behavior seems to now be that bytecode should only be
generated when explicitly requested for each contract.
* Even though PRs have merged to try to fix it, their issue seems to
persist as of v0.8.33.
# Open Questions
* Foundry:
* [x] Pruning of the AST:
* Just saw [this past
commit](https://github.com/paritytech/revive/pull/385) to not prune the
AST for Foundry compatibility.
* Can Foundry not explicitly request `"": "ast"`?
* **Answer:**
* Pruning the AST when not requested should be fine, as long as Foundry
explicitly requests it when needed.
* Will be tested by Foundry maintainer.

Changes in `docs/` (~25 files) can be skipped as they are automatically

Ran into this today, my env was set and pointing to an old version
so it's a breaking change, but I think we are better off not hardcoding
the env here, the user can do whatever they want when they invoke
compile
Separate between compilation and linker phases to allow deploy time
linking and back-porting era compiler changes to fix#91. Unlinked
contract binaries (caused by missing libraries or missing factory
dependencies in turn) are emitted as raw ELF object.
Few drive by fixes:
- #98
- A compiler panic on missing libraries definitions.
- Fixes some incosistent type forwarding in JSON output (empty string
vs. null object).
- Remove the unused fallback for size optimization setting.
- Remove the broken `--lvm-ir` mode.
- CI workflow fixes.

second take on #339
turns out that the resolve-pkg npm package was also failing to properly
resolve package with an exports field define in the package.json.
This fixes it and add a test case with such a package
Current approach fails with an 'ERR_PACKAGE_PATH_NOT_EXPORTED' error for
npm package that defines an exports field in the package.json
e.g:
> require.resolve('@redstone-finance/evm-connector/package.json')
will fail with
Uncaught:
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json'
is not defined by "exports" in
/home/pg/github/evm-test-suite/eth-rpc/node_modules/@redstone-finance/evm-connector/package.json
code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
- 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.

This pull request adds changes described in **this comment**:
- `.github/scripts/json_generator.py` - a small script that generates
several json files for different platforms.
-
[generate_versions.yml](https://github.com/paritytech/revive/compare/as-release-json?expand=1#diff-2aee05b96020ac60943e6dfcb30597e53898f31542aeb570468b970d9a13a5a6)
- the workflow that runs when release is published, creates info.json
files and pushes them into resolc-bin repo
- `js/build.js` is adjusted in order to set `RESOLC_WASM_URI` from env
variable
- ⚠️ Release workflow is changed:
- In PRs and main branch it'll only build artifacts
- Release will happen automatically only on the `v*` tag push. This is
needed for revive_web.js to have the necessary `RESOLC_WASM_URI`
- workflow will check that version in Cargo.toml is the same as the tag
when the new tag is pushed

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
