Debugging data on Alpha

[Mark Kettenis]

   Unfortunately, it's hard to construct small test cases, but when
   I'm trying to debug things inside of GCC, a fairly large precentage
   of local variables either can't be found or display as junk.

   I have no idea if this is just Alpha or not, but I think it needs
   to be fixed before 3.0: it's a very serious problem.

   Does anybody know what's going on?

When I was hacking on FreeBSD/Alpha support for GDB, I observed
similar problems.  In that case the problem was that the FreeBSD/Alpha
config files defined DBX_FUNCTION_FIRST, which caused the stabs for
local variables to be emitted before alpha_auto_offset was properly
initialized.  Now AFAICT the OSF config files do not define
DBX_FUNCTION_FIRST, but perhaps there is another reason why
alpha_auto_offset isn't properly initialized.
