Pirama Arumuga Nainar 12066c6542 Disable TestCcLibraryBp2Build in sc-dev
Bug: http://b/191166471
Bug: http://b/189438896

This test fails in sc-dev with aosp/1737314.  It passes in AOSP and
internal main branch with this change though.

Test: cherry-pick aosp/1737314 and `m nothing`

Jingwen Chen bf61afb7f7 bp2build: export some cc toolchain flags into Starlark.
This CL exports common/global/device/host clang/ld/ldd flags
from their Ninja variable initialization locations in
cc/config/global.go and cc/config/clang.go to make Bazel's cc_toolchain
and Soong's cc actions more consistent with each other.

This does not handle env-dependent or arch-specific toolchain flags
yet (logic in compiler.go and linker.go).

Lukács T. Berki a412c74fc9 Merge "Implement configured version_script." 2021-05-12 18:14:56 +00:00
Jingwen Chen 3950cd6ed4 bp2build: remove libc_tzcode from denylist.
This now works with --features no_copts_tokenization. With tokenization,
the escaped empty string '\"\"' became an actual empty string '' on the
command line, setting -DWILDABBR to the wrong value.

However, no_copts_tokenization unveiled other problems with Android.bp
flags, such as spaces in existing cflags like
https://cs.android.com/android/platform/superproject/+/master:bionic/libc/Android.bp;l=288;drc=a0a4a6c2967b5b3c02c951ea1145f32ed5564ab9
- this trips up Bazel's copts when generated literally, so the
fix (other than splitting on space and making Soong accept strings that
don't start with dashes as cflags) is to make bp2build split cflags on
spaces before generating them as copts.

Lukacs T. Berki 598dd00236 Refactor how bp2build gets arch-specific props.
Then plumb them to LabelAttribute.

This refactoring is required because the previous implementation did not
handle properties in shards other than the first one (e.g.
version_script) well. In addition, it also makes the code paths between
bp2build and analysis more similar.

Chris Parsons c424b76f76 Support multilib properties in bp2build
This combines properties among "multilib" and "arch" stanzas in selects
generated by bp2build.

With this fix, libc_gdtoa may be removed from the denylist.

This change also refactors a portion of arch.go, specifically bp2build's
arch mutator, adding a number of comments along the way, to hopefully
make this code clearer for future readers.

The comment on the interface of GetDirectDep states if there are
multiple deps with different tags, the first will be returned; however,
the current behavior is to panic if there are multiple deps. The
behavior now:
* a single dep, return the module and tag
* a single module with different tags: return module with first tag
* multiple modules: panic
* no module: return nil, nil

Jingwen Chen 4ecc67d3c5 bp2build: fix exclude_srcs in subpackages.
In a non-top level Android.bp file, exclude_srcs was not working at all
due to a bug in expandSrcsForBazel. GlobFiles was expanding a glob
relative to root, but the expandedExcludes list was relative to the
module dir, causing the glob function to not consider the
expandedExcludes list at all.

Add tests to demonstrate that this is working now.

Jingwen Chen ed9c17d033 bp2build: refactor/standardize cc_* bp2build converters
This CL refactors the cc* bp2build converters to use the common
attribute extractors in cc/bp2build.go.

This also adds include_build_directory to be handled by the compiler
attr extractor to generate recursive headers as inputs.

This also turns include_dirs and local_include_dirs into the
execroot-relative -I flags.

e.g. if a module in  bionic/libc has "private" in local_include_dirs,
the "-Ibionic/libc/private" copt is generated for it.

Jingwen Chen 91220d7334 Add os/target configurable selects for label list attributes.
This CL is pretty large, so I recommend starting with reading the newly
added tests for the expected behavior.

This change works in conjunction with the linked CLs in the Gerrit topic.
Those CLs add support for new platform() definitions for OS targets
specified in Soong's arch.go, which are configurable through
Android.bp's `target {}` property. It works similary to previous CLs
adding support for the `arch {}` property.

These configurable props are keyed by the OS: android, linux_bionic,
windows, and so on. They map to `select` statements in label list
attributes, which this CL enables for cc_library_headers' header_libs
and export_header_lib_headers props.

This enables //bionic/libc:libc_headers to be generated correctly, from:

    cc_library_headers {
        name: "libc_headers",
        target: {
            android: {
                header_libs: ["libc_headers_arch"],
                export_header_lib_headers: ["libc_headers_arch"],
            },
            linux_bionic: {
                header_libs: ["libc_headers_arch"],
                export_header_lib_headers: ["libc_headers_arch"],
            },
        },
        // omitted props
    }

to:

    cc_library_headers(
        name = "libc_headers",
        deps = [] + select({
            "//build/bazel/platforms/os:android": [
