Martin Kustermann 5cd42e6b21 [dart2wasm] Start emitting binaryen.inline custom section
Binaryen introduced `binaryen.inline` which allows us to tell it
inlining hints now, including "never inline" hint (see [0])

This allows us to remove the ugly mangling of wasm function names with
`<noInline>` postfix.

We also now pass `--strip-toolchain-annotations`: The annotations
occupy size in the wasm binary and wasm runtimes ignore them (they are
for `wams-opt` only).

Except for IR tests: Here we want to see the annotations, so we keep
them there.

We also rename the package:wasm_builder classes to clearly indicate
those are binaryen specific sections.

We also make the ir_test.dart put it's options first, allowing the IR
tests to override options if needed.

Package validation

The packages in pkg/ are automatically validated on the LUCI CI bots. The validation is largely done by the tools/package_deps package; it can be tested locally via:

dart tools/package_deps/bin/package_deps.dart

Packages which are published

There are several packages developed in pkg/ which are published to pub. Validation of these packages is particularly important because the pub tools are not used for these packages during development; we get our dependency versions from the DEPS file. It's very easy for the dependencies specified in a package's pubspec file to get out of date wrt the packages and versions actually used.

In order to better ensure we're publishing correct packages, we validate some properties of the pubspec files on our CI system. These validations include:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that we don't use relative path deps to pkg/ or third_party/ packages

Packages which are not published

For packages in pkg/ which we do not intend to be published, we put the following comment in the pubspec.yaml file:

# This package is not intended for consumption on pub.dev. DO NOT publish.
publish_to: none

These pubspecs are still validated by the package validation tool. The contents are more informational as the pubspecs for these packages are not consumed by the pub tool or ecosystem.

We validate:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that a reference to a pkg/ package is done via a relative path dependency

Adding new packages

Run gclient sync to re-generate .dart_tool/package_config.json after adding a new package.

Testing packages

Currently dart test can't be used to run the tests, use test.py as usual. E.g. the command ./tools/test.py -n...<path> runs all tests with prefix <path>.
