GCC unification, part 2. Fix various errors from previous unificaiton.
The previous version of the unified GCC compiler (Android & ChromeOS)
caused some ChromeOS tests to fail. It also caused an Android NDK
test case to fail. This CL fixes those problems. In particular it
does the following:
- Fix some file formatting errors from previous unification patch.
- Update ChangeLog files to reflect Android backport patches.
- Find and incorporate a few missing pieces from the following backports
backports from trunk r221007, r221675, r222011, r212011, r214942,
r214957, r215012, r215016, r218115, r218733, r218746, r220491. This
involved small changes in the following files:
gcc/cfghoks.c
gcc/cfgloop.c
gcc/cfgloop.h
gcc/except.c
gcc/loop-init.c
gcc/omp-low.c
- Fix minor Android test case regression introduced in the previous
unification patch.
