prologues correctly. First, prologue end is now defined by
presence of a branch, jump or call insn. Second, can no longer
fix frame offsets because we may not know the offset until after a
register has been saved.
* (v850_init_extra_frame_info): Fixup frame offsets here because
we have all the info at this time.
* (v850_frame_chain): Use new calling convention for scan_prologue.
errors unique.
* testsuite/gdb.base/nodebug.exp: Whack out all -g options
explicitly.
* v850-tdep.c (v850_init_extra_frame_info v850_frame_chain): Fix
sign bugs with scanning prologues. Get a little smarter about
calculating the length of uninteresting instructions.
LOC_LOCAL_ARG as arguments so that GDB will know about function
args declared this way. Mostly affects dwarf.
* dwarfread.c (decode_die_type): Change default type from int to
void. This allows GDB to recognize void functions.
* (new_symbol): If AT_PROTOTYPED is present, set a flag in the
type structure.
* findvar.c (extract_floating store_floating): Clean up comments
to reflect reality.
* gdbtypes.h: Add TYPE_FLAG_PROTOTYPED so that we can tell if a
function has a prototype. Currently, only dwarf supports this.
* utils.c (floatformat_from_doublest): Fix logic error with
converting from double to float. (It wasn't shifting mant_long if
it had a hidden bit.)
* v850-tdep.c: Add support for function calling. Fix some
problems with debugging code w/o debug symbols.
* config/v850/tm-v850.h: Ditto.
struct frame to make it possible to use frame_saved_args in
EXTRA_FRAME_INFO macro.
* v850-tdep.c config/v850/tm-v850.h: Lotsa new functions and
macros to make frame operations (such as backtrace) work.
