There is an internal LLVM support for unwinding backtrace with an
attempt to print a meaningful information on a crash signal.

I assume that there is a crash in the unwinder code causing recursive
execution of a signal handler.

There was also a post-6.0 patch:

Fix llvm-config --system-libs output on FreeBSD and NetBSD

https://github.com/llvm-mirror/llvm/commit/daf294622383687adc281dd695acf4533caf0357

Not sure if it is of any help, but it's worth to backport it to 6.0.

llvm self-tests looping(?)

2018-04-01 Thread Havard Eidnes 
Hi,

I decided it might be a good idea to run the self-tests in llvm
5.0.1 on powerpc.  However, after the test and utilities are
built, it appears to spin while doing the first test.  The run
log shows:

[100%] Built target LLVMHello_exports
[100%] Built target LLVMHello
Scanning dependencies of target check-llvm
[100%] Running the LLVM regression tests
-- Testing: 21465 tests, 1 threads --
Testing: 0 ..

and the process is spinning consuming CPU (well, it's stopped in
the debugger here):

  PID USERNAME PRI NICE   SIZE   RES STATE  TIME   WCPUCPU COMMAND
0 root 1260 0K   22M pgdaemon 600:47  0.00%  0.00% [system]
19597 root  28443M   15M STOP 306:27  0.00%  0.00% SupportTests

and the debugger points towards libexecinfo:
