1681209 - Create fuzzing builds for use with Pernosco

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, task)

Description

[Tyson Smith [:tsmith]]

The existing fuzzing builds are built with optimization levels >0 and this results in Pernosco sessions that can be difficult to use.

In order to automate collecting rr traces to submit to Pernosco we require two additional builds that mostly match the existing fuzzing ASan and debug builds.

-ac_add_options --enable-optimize="-O2 -gline-tables-only"
+ac_add_options --enable-optimize="-O0 -g"

These builds do not need to be tested and they do not need to be stored for longer than a week.

As for naming fuzzing-asan-noopt and fuzzing-debug-noopt work for me unless there is a naming convention I'm missing.

Try -Og?

Yes, I believe it maps to "-O1" (clang).
