* Fix foreign frame problem in C++ exception unwinding. PR 20939. [2/10]
Being discussed. We agreed on the approach fixing the bug. Need a
patch.
Find other issues during the investigation, and fixed them. PR 20953,
PR 20954, and PR 20955 are fixed.
* GDB exception handling is broken on i686-w64-mingw32. PR 20977. [3/10]
In short, we can't use longjmp in SJLJ exception handling. Need post
an RFC.
* Upstream patches review. [5/10]
** SVE GDB patches review.
Carefully read the patches line by line for the first time. Find some
issues on target descriptions, and post my comments upstreams. Hack
GDBserver to get SVE on normal juno board. Need more time to think
about how to move on.
** Review sparc target descriptions.
** 7.12.1 release discussion.
