From 7a3681e5b6c39bc2b3b62031ca5941dbf7bc4e63 Mon Sep 17 00:00:00 2001 From: Christopher Ferris Date: Mon, 24 Apr 2017 17:48:32 -0700 Subject: Move libc_log code into libasync_safe. This library is used by a number of different libraries in the system. Make it easy for platform libraries to use this library and create an actual exported include file. Change the names of the functions to reflect the new name of the library. Run clang_format on the async_safe_log.cpp file since the formatting is all over the place. Bug: 31919199 Test: Compiled for angler/bullhead, and booted. Test: Ran bionic unit tests. Test: Ran the malloc debug tests.
