Reduce binary size by 44 KiB (STL streams -> std::string) Thanks to the analysis of b/71844955#comment14, I managed to spot a case of C++ streams codegen euforia. Reimplementing the same function on top of std::string saves 44 KiB (measured before and after on a standalone releade build on arm64) TBR: hjd Test: run tools/update_protos.py --whitelist tools/ftrace_proto_gen/event_whitelist out/mac_debug/ftrace_proto_gen ./src/ftrace_reader/test/data/android_seed_N2F62_3.10.49/events protos/ftrace/ and check that there are no diffs in proto/ Bug: 71844955 Change-Id: Ifc93b435c639d0ec815e5958b1e1ff504177f1bb
This project is meant to be built both as part of the Android tree and from a standalone checkout
For internal docs see this page
Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.
This project uses Android AOSP Gerrit for code reviews and uses the Google C++ style. Currently targets -std=c++11.
You can use both git cl upload from Chromium depot tools or Android repo to upload patches.
git cl is quite convenient as it supports code auto-formatting via git cl format.
