Rather than having a monolithic third_party/BUILD.bazel, this moves
our Dawn rules to their own subdirectory and makes it callable via
@dawn instead of //third_party/dawn.
This will help with the G3 roll and make our rules more organized in
general.
This also rolls Dawn
Roll Dawn from ab9757036bd6 to e831fb61046b (22 revisions)
https://dawn.googlesource.com/dawn.git/+log/ab9757036bd6..e831fb61046b
Suggested Review Order:
- WORKSPACE.bazel, where we define @dawn and its deps
(@vulkan_headers and @vulkan_tools). I initially thought
I needed to define all of Dawn's deps in the workspace_file_content
for new_local_repository, but that WORKSPACE file is
ignored when building Skia rules.
- third_party/dawn/BUILD.bazel, the contents of which were copied
from //third_party/BUILD.bazel and modified largely via
find-and-replace to point to files relative to
//third_party/externals/dawn. One exception is the cpu_wasm
config_setting because @dawn isn't able to see Skia's
//bazel/macros.bzl.
- All other files

G3 prefers license() first.
This was done mechanically with a big find/replace

Ran the following commands:
find -name "BUILD.bazel" -exec sed -i -e '1iload("//bazel:macros.bzl", "cc_library", "exports_files_legacy")\nexports_files_legacy()' {} +
buildifier --lint=fix --mode=fix -r .
This had the effect of making sure we can export all of our
files in G3 (until we no longer have legacy targets) and
making all of our cc_libraries shim-able.
bazel/macros.bzl has the human-contributed changes, the rest
were mechanical.

PS1 regenerates BUILD.bazel files
I suggest reviewing the deltas between PS1 and the latest
PS to focus on the interesting bits.
The changes here allow for a Vulkan-only build of HelloWorld
based on sk_app. The toughest change was properly fetching
the VisualID after removing the gl calls that used to
fill that in.
There are a few changes that fix resolution of Dawn
header files, but those won't actually be built until
a follow-on CL.

- Use latest emscripten toolchain (3.1.0)
- Autogenerate the atoms and manually fix some of the file lists.
- Add a known_good_builds target to bazel/Makefile to help
check the things we expect to work with Bazel.

This uses the gazelle extension from
https://skia-review.googlesource.com/c/buildbot/+/473357
Review Tips:
- Ignore any changes to .h or .cpp files. Those have been
pulled out into their own CLs.
- Start with bazel/macros.bzl.
- Read the CL with the generation code, if you haven't already.
- Look at third_party/file_map_for_bazel.json.
- See experimental/bazel_test for an idea of how a cc_binary
would be made.
- Spot check one or two of the BUILD.bazel files.
This CL generates the "atomic" rules for src/, include/ and
modules/skshaper, as a starting point.
`bazel build --config clang //include/...` works
`bazel build --config clang //src/...` starts compiling,
(which verifies that the BUILD.bazel files are all valid),
but runs into errors because not all third_party deps have
been resolved, and there are some files missing from the
toolchain still (e.g. EGL headers).

These rules can be used to build our GMs on WASM+WebGL and
libskia.a with just the CPU backend (and most other features
turned off).
This can be done with the following commands:
- bazel build //modules/canvaskit:gm-bindings-wasm --gpu_backend=gl_backend --with_gl_standard=webgl_standard
- bazel build :skia-core --config clang
This pivots slightly from http://review.skia.org/463517
by using config_settings [1] instead of platforms for
the optional features that we control. This pivot was
suggested in [2]
We have BUILD.bazel files in many of the subdirectories
that specify filegroups for the appropriate files. In
an effort to make //BUILD.bazel more readable, it is
the responsibility of these subfolders to deal with
conditionally including certain .h or .cpp files.
This is done using select statements and config_settings
or platform constraints as necessary.
For example, src/gpu/BUILD.bazel will different private
filegroups for each of the supported gpu backends [3]
and a more-visible filegroup called "srcs" that has
the right selection of the private files to be used
for compilation.
An effort has been made to avoid using glob() in our
BUILD.bazel files. These file lists were made by using
`ls -1` and some regex to add in quotes. We might want
to make a helper script to assist with that, if necessary.
To specify which options we have, the settings in
//bazel/common_config_settings/BUILD.bazel have been
redesigned. They make use of a macro `string_flag_with_values`
that removes the boilerplate. Patchset 36 shows what the
file looks like w/o the macro.
The top level BUILD.bazel file will still need to use
some logic to handle defines, because local_defines is
a list of strings, not a list of labels [4].
Suggested Review Order:
- WORKSPACE.bazel to see the new dependencies on the
emsdk toolchain and bazel_skylib
- bazel/common_config_settings/* to see the few settings
defined (we have more to define, see BUILD.gn and
//gn/skia.gni for ideas)
- BUILD.bazel to see the "skia-core" cc_library rule.
See also "gms" and "tests"
- modules/canvaskit/BUILD.bazel to see the use of
the emscripten "wasm_cc_binary" rule, which depends
on the "skia-core", "gms", and "tests" rule. Note that
it only builds some of the gms as a proof of concept.
- The other BUILD.bazel files. Some of these are not
platform or feature dependent (e.g. pathops). Others
are (e.g. gpu).
- All other files.
