Subject: Question on power-core.xml, register: r1.
Date: Fri, 09 May 2008 23:41:00 -0000	[thread overview]
Message-ID: <Pine.LNX.4.64.0805091823590.22847@ld0159-tx32> (raw)

Hello,

  Per Appendix F, Sec. F.3 Predefined Target Types, of the GDB User Manual:

  code_ptr
  data_ptr
     Pointers to unspecified code and data. The program counter and any
  dedicated return address register may be marked as code pointers; printing
  a code pointer converts it into a symbolic address. The stack pointer and
  any dedicated address registers may be marked as data pointers.

  I note the use of the term: "may"; while power-core.xml marks 'pc' and 'lr'
  as type="code_ptr", it does not mark 'r1', the stack-pointer as
  type="data_ptr". Is there a specific reason why this is so? It's type="uint32";
  marking 'pc' & 'lr' as type="code_ptr" has the advantage of converting their
  values into symbollic address, what would happen (and is not) were 'r1' to be
  marked type="data_ptr"?

Thanks,
Anmol.
