/* The following is the intended naming schema for frame functions.
It isn't 100% consistent, but it is aproaching that. Frame naming
schema:
Prefixes:
get_frame_WHAT...(): Get WHAT from the THIS frame (functionaly
equivalent to THIS->next->unwind->what)
frame_unwind_WHAT...(): Unwind THIS frame's WHAT from the NEXT
frame.
put_frame_WHAT...(): Put a value into this frame (unsafe, need to
invalidate the frame / regcache afterwards) (better name more
strongly hinting at its unsafeness)
safe_....(): Safer version of various functions, doesn't throw an
error (leave this for later?). Returns non-zero if the fetch
succeeds. Return a freshly allocated error message?
Suffixes:
void /frame/_WHAT(): Read WHAT's value into the buffer parameter.
ULONGEST /frame/_WHAT_unsigned(): Return an unsigned value (the
alternative is *frame_unsigned_WHAT).
LONGEST /frame/_WHAT_signed(): Return WHAT signed value.
What:
/frame/_memory* (frame, coreaddr, len [, buf]): Extract/return
*memory.
/frame/_register* (frame, regnum [, buf]): extract/return register.
CORE_ADDR /frame/_{pc,sp,...} (frame): Resume address, innner most
stack *address, ...
