Upstream provides a DTC_VERSION preprocessor macro to its C code by
generating a version_gen.h header from either of its supported build
systems: Make formats the header from its internal variables (VERSION,
PATCHLEVEL, SUBLEVEL, ...) while Meson uses its vcs_tag() function on
a template, version_gen.h.in.
As AOSP doesn't make use of these build systems, aosp/204511 decided to
hardcode a version_non_gen.h file and patch the corresponding #include.
This unsurprisingly ended up bitrotting as the repo was being upgraded.
Instead, replicate the version_gen.h.in patching in our build systems,
extracting the version number from the METADATA file, which
external_updater.sh will keep up-to-date. Note that this introduces a
dependency on sed in the genrule(), the impact of which is minimized by
making METADATA_version.sed POSIX-compliant.
Keep appending the suffix '-Android-build' to the upstream version.
Test: m dtc && ${ANDROID_HOST_OUT}/bin/dtc --version
Test: bazel build //:dtc && bazel-bin/dtc --version

// Added automatically by a large-scale-change that took the approach of

|
// 'apply every license found to every target'. While this makes sure we respect
|
|
// every license restriction, it may not be entirely correct.
|
|
//
|
|
// e.g. GPL in an MIT project might only apply to the contrib/ directory.

|
// Please consider splitting the single license below into multiple licenses,
|
|
// taking care not to lose any license_kind information, and overriding the
|
|
// default license using the 'licenses: [...]' property on targets as needed.
|
|
//
|
|
// For unused files, consider creating a 'fileGroup' with "//visibility:private"
|
|
// to attach the license to, and including a comment whether the files may be
|
|
// used in the current project.
|
|
//
|
|
// large-scale-change included anything that looked like it might be a license
|
|
// text as a license_text. e.g. LICENSE, NOTICE, COPYING etc.

|
|
// Please consider removing redundant or irrelevant files from 'license_text:'.
