Slava Egorov a17d709a1d Revert "[tools] Allow precompiling gen_kernel and compile_platform" ... This reverts commit 5cda2a871c. Reason for revert: broke Flutter build. Original change's description: > [tools] Allow precompiling gen_kernel and compile_platform > > When iterating on core library changes or changes in the AOT compiler > many seconds are wasted waiting on gen_kernel/compile_platform to > parse Dart code. This happens because we are running these tools > from sources on prebuilt Dart SDK. > > This CL allows SDK developer to opt-in into AOT compiling these > tools by adding `precompile_tools=true` to their DART_GN_ARGS. > > AOT compilation is performed using prebuilt SDK - so these > executables do not need to be recompiled if core libraries or > VM changes reducing iteration cycles. > > pkg/vm/tool/precompiler2 is tweaked to detect when DART_GN_ARGS > contains `precompile_tools=true` and use precompiled > gen_kernel.exe instead of running it from source. > > Using precompiled compile_platform takes vm_platform_strong.dill > build from 20 seconds to 3 seconds. > > Using precompiled gen_kernel takes small benchmark build from > ~10 seconds to 2 seconds. > > TEST=manually tested > > Change-Id: Ieec6ad4e1081023d140eb744f0a3cd0c754414ca > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/367940 > Commit-Queue: Slava Egorov <vegorov@google.com> > Reviewed-by: Martin Kustermann <kustermann@google.com> Change-Id: Id3e4eb44d33516f31c165d9a1e55911e8d356e7f No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/367960 Commit-Queue: Slava Egorov <vegorov@google.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Alexander Markov <alexmarkov@google.com>		2024-05-23 13:52:58 +00:00
