[llvm-dev] ORC JIT Weekly #8: Basic OrcV2 C Bindings, MachO and COFF improvements.

[Lang Hames via llvm-dev]

Hi All,

The JITEventListener support (https://reviews.llvm.org/D75838) has been
re-enabled with fixes in 39253a50f0f.

Andres -- Let me know if/when you want to test this out and add C API for
it.

Regards,
Lang.
