- If no system_shared_libs is specified, bp2build writes no attribute
value. In this case, the bazel library macros determine the correct
default behavior.
- If any system_shared_libs is specified for any variant, then bp2build
writes the value verbatim. This includes if an empty list is specified,
as this should override defaulting behavior.
Note this defaulting behavior is incomplete and will be incorrect in
corner cases. For example, if, in an Android.bp, system_shared_libs is
specified for os.linux_bionic but not for os.android, then the bazel
default for os.android will be incorrect. However, there are no current
modules in AOSP which fit this case.
As a related fix, supports static struct for cc_library_static.
Also, removes some elements from the bp2build denylist.

This fixes a bug which was a misunderstanding of soong properties:
Soong's cflags pertain only to C and C++ language, whereas bazel's copts
pertain to all three languages. This change ensures that asflags are
added as specifically asflags, and the 'copts' for the static library
macro pertains only to C and C++ languages.
This requires a somewhat hacky workaround for asflags, however: Since
assembly sources also need includepath-related flags, this duplicates
these flags between copts and asflags. To reduce verbosity of
bp2build-generated targets, this also ensures that asflags are omitted
in cases where there are no assembly sources.

This CL adds support for cc_library to correctly split c, as and cpp
srcs in shared/static nested props, as well as splitting
the *filegroup* deps in those props, where each filegroup is expanded

correct sources go into cc_library_static's underlying cc_libraries for
c, cpp and as sources respectively.

This allows removal of almost all current items from the mixed build
denylist, which were previously broken due to being unable to separately
control flags for compilations of different languages within the same

Note that this does not appropriately implement asm/c srcs and flags for

followup.

At least until libc and libm builds, which are the common values in
system_shared_libs. We don't have a way to break the cycle of:
libstdc++.so (system_shared_libs) -> libc.so -> ...(whole_static_libs) -> libstdc++.a (system_shared_libs) -> []
because bp2build just sees it as:
libstdc++ (system_shared_libs) -> libc -> (whole_static_libs) -> libstdc++ (system_shared_libs) -> libc -> ...
therefore creating a cycle.
This CL punts the problem for now by ignoring system_shared_libs in the cc deps mutator, with a TODO.

Change-Id: Id4744593af39b7eb3b31418c8afaeeac99a0ab5f
There are two pieces to make this work:
1. Local include paths must include $(BINDIR)-relative paths, to support
generated headers in those directories.
2. The srcs that bp2build outputs for BUILD targets must include labels
for targets given in generated_hdrs and generated_srcs.
Support for exported_generated_hdrs intentionally deferred.
This allows us to remove several targets from the bp2build denylist.
Some are moved to the mixed build denylist, because genreated headers are
still unsupported in mixed builds.

This is so that its implementation is more amenable to implementing
`target: { android_arm: { ... } }` and the like.
In addition, add a Boolean return value to getChildPropertyStruct() and
use it at every call site so that we only merge property structs when it
makes sense.

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.

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

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.

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": [
