RE: cross targeted gdb and corefiles

["Kevin \"Squail\" Endres" <kevine@wildseed.com>]

after looking at this a bit deeper i am still confused.

i added the below .o's to TDEPFILES in the Makefile.

i moved the supply_* functions from i386-nat (only ones i could find in the
gdb source)to arm-linux-tdep.c.
(given that there is no fp on arm - is the supply_fpregset really
necessary???)

in the function supply_gregset i have an extern 'regmap[]' - I see in the
source where this is defined for i386 - but where is it defined for the arm
target???

:]k

getting todays source and configuring... keep on timing out- will this
change work with the released 5.2?

as to the change I am not that familure with gdb source and structures. 

I am assuming that by "link in corelow/core-regset as target instead of nat
objects" you are directing me to alter the NATDEPLIST list in gdb's Makefile
- removing all *nat*.o references and add reference to corelow.o and
core-regset.o. I am puzzled why post config the first line of NATDEPLIST is
commented out...

as for "move supply_gregset and supply_fpregset to the tdep file" - move
from where(assumed a nat file) to which tdep file(arm-linux-tdep.c or
arm-tdep.c??)

I appreciate your help and apologize for the "newbie" questions....

:]k

He's on GNU/Linux, IIRC...

Doing cross coredumps is trivial; I put all the BFD machinery in place
for a number of GNU/Linux targets, and others did it for the various
BSDs.  I'd post my ARM patches for this but I doubt even a line of them
applies any more after your extensive ARM cleanups.

The only thing you have to do is move supply_gregset and
supply_fpregset to the tdep file, and then link in corelow/core-regset
as target instead of nat objects.  This means a little bit of grubbing
about in target header files to copy out definitions for regsets, but
only a little.
