In general, that's obviously a good idea. Having said that,
carlton_dictionary-branch is attempting a delicate enough task that I
suspect that, in some circumstances, we'll have to accept regressions.
It's trying to convert GDB from using the wrong names for things to
using the right names for things, and to do this whenever possible in
the presence of inadequate debug information; doing this while
simultaneously supporting the bugs and foibles of multiple versions of
GCC is a very hard task, and one which can adversely affect GDB's
maintainability.

But, at the very least, all regressions should be analyzed, so we can
figure out what's causing them, in what circumstances they will crop
up, and how easy they would be to fix.
