Re: PATCH: use frame_unwind_register instead of frame_register
I've committed the below, which 1) uses frame_register_read instead of
frame_unwind_register, thereby obtaining the registers from the right
frame, and 2) removes the now-unused variables.
2006-11-06 Jim Blandy <jimb@codesourcery.com>
* (dwarf_expr_read_reg): Use frame_register_read, not frame_register.
* dwarf2loc.c (dwarf_expr_read_reg): Use frame_register_read
instead of frame_register. Doc fix.
