Re: [rfa/doco] PROBLEMS: add regressions since gdb 6.0

While we're updating PROBLEMS, is the list of targets that don't use
the new frame code accurate?  (Sparc, mips, ppc, arm.)


Do users care?  What user-level effect will one see on those targets
that don't use the new frame code?

IMHO, if there are no user-level issues, we shouldn't mention this in
PROBLEMS.

- arches using the old frame stuff are typically in worse shape
- arches using the old frame stuff can't use CFI (i.e., can't use exploit GCC's frame debug info)


the second one in particular is of issue to users - it affects GDB's ability to do decent backtraces (especially through glibc).

Yes, the list needs updating, SPARC and ARM are done. MIPS and PA are "done" (it lost the signal stuff). For PPC, that will be 6.2, which leaves a few strays.
