The roll causes a breakage on V8 arm cross-compile debug:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Arm%20-%20debug%20builder/builds/3144

I was able to repro that locally (also made sure that it fails with the clang update only, also clobbered):
fetch v8
cd v8
git checkout 0ed1254d8
gclient sync
build/linux/sysroot_scripts/install-sysroot.py --arch=arm
tools/dev/v8gen.py -m client.v8.ports -b "V8 Arm - debug builder" arm
ninja -C out.gn/arm -j1000 d8

This only affects the debug build. Any ideas? I reverted our side of the roll in the meantime.

machenbach: That's probably  issue 648800 . Give that build symbol_level=1 or 2, then it'll build faster too.
