JIT crashing when compiling source code with Clang and -mretpoline flag
...that file in an old MCJIT implementation I had - there the application crashed when calling the function (but it does find the address for the function first).
If I recompile my code without the "-mretpoline" flag, everything works fine again.
I compiled Clang and the LLVM files from the LLVM8 source files, I run them under Windows7 64bit. Any ideas what might went wrong?
Kind greetings

ORC error: No callback manager available
Hi LLVM Developers,
I have a query about an LLVM error message that I'm encountering and I
hope it's appropriate to post to this mailing list about it.
Postgres can be built with LLVM-based JIT support.
I find that when running on Linux (RHEL8) on IBM Z hardware, using
LLVM8+, I'm seeing many instances of the following LLVM error message
appearing in the Postgres server log:
ORC error: No callback manager available for s390x-ibm-linux
(strangely, it otherwise doesn't seem to be causing any problems)
Looking through the LLVM source code, it appears that f...

AARCH64 Code Size regression between 6/7
I did a bit more poking, using llvm/clang versions 6-8. The IR in all
cases appears fundamentally identical. I ran the IR generated by version 6
through llc on all three versions. llc-7/8 produced the extra ADRPs, llc-6
did not. So (to my untrained eyes), the IR is generated the same, it is in
the IR->AARCH64 asm pass that the extra instructions are being generated.
