Bug 1765543 added a task that uses --disable-new-pass-manager, but that option is not supported anymore with clang trunk.

New pass manager is not supported by AFL or AFL++ from what we know. I assume that they will work on porting their instrumentation pass over to the new system now that the old one will be removed. Truber, can you check with the AFL++ authors?

It looks like this is already done as of the past couple months (AFLplusplus#1100). I'm trying now.

This builds and instruments the code for AFL. With -flegacy-pass-manager the build was successful but the code wasn't actually being instrumented.
The instrumentation breaks xpcshell startup which is used during packaging for normandy, so I've disabled that step for now and logged 1770223.

AFL++ compiler wrapper depends on the compiler version used to build it. Is there a way to invalidate the toolchain when linux64-clang version changes?

That happens automatically.
