Need advice on building GDB for a large number of PowerPC variants.

Need advice on building GDB for a large number of PowerPC variants.

[Anmol P. Paralkar]

Hello,

  I need to build GDB for a debugging a variety of PowerPC families.
  The host environment is x86 plus a small subset of the PowerPC
  variants. GDB will be used native as well as cross (remote) from
  each host (x86 (cross-only) as well as PowerPC). A substantial
  number of PowerPC flavours is desired to be targetted - the number
  of families and the instances within each family all result in a
  fairly large number of individual targets. Both the variations in
  configurations: powerpc-linux-gnu as well as powerpc-eabi are needed
  for almost each individual target.

  I reckon that I only need build:

  * GDB in both eabi and linux configurations per host; any desired
    target can be debugged by doing a 'set architecture' for it.

    That way the number of GDB's built is two per host.

  as against:

  * A GDB per (host, target) combination of interest.

    Which will needless to say, will result in a large number of
    GDB executables needed to be built.

  Please could you tell me if my reasoning is correct or am I missing
  something essential?

  Thank you very much for your help.

Best Regards,
Anmol P. Paralkar

Hello,

  Forwarding Michael Snyder's affirmation below. (For some reason, his
  response bounced off the mailing list server). Someone else might
  need to benefit from this, hence the forward.

Best Regards,
Anmol.
