Re: [DynInst_API:] dyninst 10 on ppcle and aarch

[Stan Cox <scox@xxxxxxxxxx>]

I poked at this a bit more and it is looping in 
int_process::waitAndHandleEvents(bool block)
I ran the previously posted test on ppcle XX

./mutatee.10 100 & DYNINST_DEBUG_STACKWALK=1 DYNINST_DEBUG_THREAD=1 
LD_LIBRARY_PATH=/root/dyninst-10.0.0/install/lib 
DYNINSTAPI_RT_LIB=/root/dyninst-10.0.0/install/lib/libdyninstAPI_RT.so 
./mutator.10  $!
captured the output of that, then to trim it down a bit ran it through:
 awk '/mailbox size/ {print "##### " $0} /Event.*added/ {print $0} 
/Handling event/ {print $0}'
which results in (repetition at #####)

REPEAT REPEAT REPEAT...

Doing the same on x8664 yields no Signal event (and no looping)
