Hi,
the second patch to prepare the calling convention stuff. It just adds
the parse_dwarf2_calling_convention functionality to gdbarch. The
below patch contains only the patch to gdbarch.sh (not the auto-generated
gdbarch.[ch]) and the new default_parse_dwarf2_calling_convention function
in arch-utils.
Ok to apply?
Corinna
* gdbarch.sh (parse_dwarf2_calling_convention): New method.
* gdbarch.h, gdbarch.c: Re-generate.
* arch-utils.c (default_parse_dwarf2_calling_convention): New function.
* arch-utils.h (default_parse_dwarf2_calling_convention): New extern
declaration.
