All "unhandled instruction" shown in the first report should now be supported by GetInstructionSize in
main and release/20.x branches. Chances should be better now to run instrumented binaries in Wine.

[trcrsired]

what about windows on arm support for asan ubsan and fuzzer?

This issue seemed to be about x86_64 and "unhandled instruction", so I guess arm support may deserve its own issue?
