Andrew,
Here is the patch to stub libunwind for ppc64, as we had discussed a
few days.
It has three parts, all of which are attached below.
1. patch to enable use_libunwind on ppc64 (in common/m4/frysk-
use-libunwind.m4)
2. patch to bootstrap libunwind auto make and lib/unwind makefile.gen
(in frysk-imports/bootstrap.sh)
3. the actual libunwind stubs for ppc64. (in frysk-imports/libunwind)
I had tested it on ppc64, it can build ok without any extra patch.
I also tested the patch on x86, no regression found.
Any comments?
