The flutter engine DEPS got new icu/boringssl so this CL can safely land and roll into engine. A small change is made in Patchset 1..3. This removes special logic for creating the `dart-sdk` we distribute which used to build release and product mode and copied some binaries from the latter into the former, before the SDK was actuallly ready to test and distribute. This changes the GN build rules to build the necessary gen_snapshot/dart_precompiled_runtime product binaries during the normal release build. Normally during --mode=product builds the global build config in //build/config/BUILDCONFIG.gn will set `-fvisibility=false`. => Doing so results in much smaller binaries - because only explicitly exported symbols are visible, the rest can be tree shaken by the linker. Since we are building --mode=release, the `-fvisibility=false` will not be set. In order to set the flag for the 2 special product-mode binaries we need to add -fvisibility=hidden manually, in: * dart_product_config: Which is used for compiling VM sources. * 3rd party double-conversion library * 3rd party boringssl library * 3rd party icu library The upstream CLs are: * BoringSSL: https://dart-review.googlesource.com/c/boringssl_gen/+/150482 * ICU: https://chromium-review.googlesource.com/c/chromium/deps/icu/+/2236407 Issue https://github.com/dart-lang/sdk/issues/42230 Change-Id: I8d9b37acbb5eb94e44d97652f838948a946fd372 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/151505 Commit-Queue: Martin Kustermann <kustermann@google.com> Reviewed-by: Alexander Thomas <athom@google.com> |
