== GDB ==
* Committed fix for the GDB part of #620611 (Unable to
backtrace out of vector page 0xffff0000) to mainline and
Linaro GDB 7.2.
* Ran into GDB crashes due to memory corruption in tests
involving multiple inferiors. Tracked down root cause
(using valgrind) to long-standing double free bug in GDB
terminal state handling code. Committed fix to mainline
and Linaro GDB 7.2.
* While using valgrind (see above), ran into problems:
* ptrace system call is unsupported on ARM
* certain variants of the "SUB from SP" Thumb-2 instruction
are not handled by the VEX compiler
Fixed both problems locally, and was then able to successfully
valgrind GDB on ARM.
* Created Linaro GDB 7.2-2011.03-0 release.
* Worked on glibc patch to add ARM unwind tables to system
call stubs; this will help unwinding in the absence of
debug info for libc, and in particular fix #684218 (Failures
in gdb.base/call-signal-resume.exp)
