Subject: Thu Apr 22 14:50:05 1993 Jim Kingdon (kingdon@cygnus.com)
* symtab.h: Fix LOC_REF_ARG comment.
Wed Apr 22 20:21:30 1993 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
and Jim Kingdon (kingdon@cygnus.com)
* stabsread.c (define_symbol): Combine a 'p', 'r' arg pair to a
LOC_REGPARM symbol.
* config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Revise comments.
symfile.c (compare_symbols): Don't check first character; STRCMP
does that.
* stabsread.c (define_symbol): Generate a LOC_REGPARM_ADDR for
structures that are passed by address in a register.
* symtab.h (enum address_class): Add LOC_REGPARM_ADDR.
* findvar.c (read_var_value),
printcmd.c (address_info, print_frame_args),
stack.c (print_frame_arg_vars), symmisc.c (print_{,partial_}symbol),
* symtab.c (lookup_block_symbol): Deal with it.

/* When passing a structure to a function, Sun cc passes the address

- two symbols, so we get a LOC_ARG saying the address is on the stack
- (a lie, and a serious one since we don't know which register to
- use), and a LOC_REGISTER saying that the struct is in a register
- (sort of a lie, but fixable with REG_STRUCT_HAS_ADDR). Gcc version
- two (as of 1.92) behaves like sun cc. REG_STRUCT_HAS_ADDR is smart
- enough to distinguish between Sun cc, gcc version 1 and gcc version 2.

This still doesn't work if the argument is not one passed in a
register (i.e. it's the 7th or later argument). */
