- Subject: [PATCH 4/4] Activate JIT code unwinder for i386.
- References: <1309847489-13760-1-git-send-email-sanjoy@playingwithpointers.com>
Registers the (pseudo) unwinder for JIT code for i386. This can probably be expanded to other architectures after some testing and review.
gdb/ChangeLog:
* i386-tdep.c: Activate JIT unwinder for i386.
