Pulled down depot tools and v8 source. Then built v8 using fuzzbuild.sh.

1$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

1$ export PATH=/path/to/depot_tools:$PATH

1fetch v8

gclient sync

BUild

1./build/install-build-deps.sh

1cp ../fuzzilli/Target/v8/fuzzbuild.sh .

1./fuzzbuild.sh

Lets go, always be fuzzing.

C++

I also don’t know c++ which is a bit of an issue when working on a large C++ codebase like v8 so I’ve been going through learncpp.com so far I’ve found it very helpful and interesting.

d8 is crashing which is very strange. Looks like it’s segfaulting when collecting coverage. Goign to attempt to rollback and see if still works. Rolling back to b7ed978e41b4bac7802b206404d0e2f3d09f31ac. Very strange it’s crashing though on startup. Inch resting. Rebuilt at the commit we’ll see if it runs.

Got to here on learncpp.com
