llvm dev - Apr 2020 - ORC JIT Weekly #7 -- JITEventListener support and Swift Immediate Mode Migration

Finally, I found the time to try it out again. And it works fine in LLVM
master. I haven't tried any other LLVM version.

Profiling with perf on assembly level works fine. And so does gdb. One
can set pending breakpoints on the to be generated function and
execution stops when calling the function which shows that the jit
integration in gdb works. I have not played around with debug
information.

For the perf support, it's a bit of a pain to remember to enable
LLVM_USE_PERF when building LLVM. Why not enable it by default?

Best regards,
Frank

Have you had any success in identifying the root cause of this problem?  I'm
being bitten by it to, and moving to LLVM master is not currently an option for
my project.

No, I have not investigated the issue anymore.
