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 -----Original Message----- From: Kevin "Squail" Endres [mailto:kevine@wildseed.com] Sent: Thursday, May 16, 2002 11:35 AM To: 'Daniel Jacobowitz'; Richard.Earnshaw@arm.com Cc: gdb@sources.redhat.com Subject: RE: cross targeted gdb and corefiles 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 -----Original Message----- From: Daniel Jacobowitz [mailto:drow@mvista.com] Sent: Thursday, May 16, 2002 10:42 AM To: Richard.Earnshaw@arm.com Cc: Kevin Squail Endres; gdb@sources.redhat.com Subject: Re: cross targeted gdb and corefiles On Thu, May 16, 2002 at 06:24:53PM +0100, Richard Earnshaw wrote: > > I am using a gdb built from a cvs snapshot from 4-29 that is i386 hosted and > > ARM targeted. > > > > this gdb does not support reading arm cores.

Some targets can now do this. Precisely which target OS are you > using? 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. -- Daniel Jacobowitz Carnegie Mellon University MontaVista Software Debian GNU/Linux Developer
