Re: [patch/rfc] FRAME_FP() -> get_frame_base()


On Nov 19,  2:55pm, Andrew Cagney wrote:


The mechanics of the change are obvious. The new function's name, though, is not. The following names come to mind:

get_frame_base()
Hints that the address is some how associated with the frame's base. Hopefully this conveys the notion that the address shouldn't change throughout the lifetime of the frame.

get_frame_address()
Like get_frame_base() but without that strong association with the frame's base. It does fit in well with the gdbarch methods frame_locals_address() and frame_args_address() though.

get_frame_fp()
Would associate the address with the `frame-pointer'. I don't like this one since, in the past, FP has been too closely associated to a real register, and the register definitly changes across the lifetime of the frame.

Preferences?

I think get_frame_base() is a good choice.  I like get_frame_address()
too, but if using "base" somehow helps us to remember that this
address remains constant, then that's a good thing.

[...]

- (I guess) re-vamp the PPC so that get_frame_base() is constant through out the lifetime of a frame.

Yes, I guess so.  I had to think about this a while though -- the current
placement of ->frame makes a lot of sense.

Any other votes?
