symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)

resources.
(add_psymbol_to_list, add_psymbol_addr_to_list): Initialize new
psymbol using the psymbol bcache.
(init_psymbol_list): Psymbol lists now contain pointers rather than
the actual psymbols.
* symfile.h (psymbol_allocation_list): Psymbol lists now dynamically
grown arrays of pointers.
(ADD_PSYMBOL_VT_TO_LIST): Initialize new symbol using the psymbol
bcache.
* symmisc.c (print_partial_symbols): Now takes pointer to pointer
to partial symbol.
(print_symbol_bcache_statistics): New function to print per objfile
bcache statistics.
(print_partial_symbol, print_partial_symbols,
maintenance_check_symtabs, extend_psymbol_list):
Account for change to pointer to pointer to partial symbol.
* symtab.c (find_pc_psymbol, lookup_partial_symbol, decode_line_2,
make_symbol_completion_list):
Account for change to pointer to pointer to partial symbol.
* symtab.h (bcache.h): Include.
* xcoffread.c (xcoff_start_psymtab): Make global_syms & static_syms
type "partial_symbol **".

stabsread.c (define_symbol, read_member_functions, read_struct_fields),
symtab.h (OPNAME_PREFIX_P, VTBL_PREFIX_P, DESTRUCTOR_PREFIX_P),
values.c (vb_match): Use is_cplus_marker instead of comparison

collision in C++.
* infcmd.c (path_command): Use empty string if PATH name not set.
* i386-tdep.c (skip_trampoline_code): New function.
* srec.c: Renamed dsrec.c to avoid filename collision.
* Makefile.in: Cope with renaming.
Update copyrights to 1996.
the step range test. Replace call detection test with much
simpler (and more efficient) test that doesn't require prologue
examination (as often).
* symtab.c symtab.h (in_prologue): New function that indicates
whether or not we are in a function prologue. This uses the
symbol table, and then falls back to prologue examination if that
fails. It's much more efficient for remote debugging because it
avoids examining memory, which is very slow. This is used in
wait_for_inferior to determine if we've made a function call that
needs to be skipped over (for next/nexti).
* mips-tdep.c (after_prologue): New function, returns the PC
after the prologue. Uses PDRs and the symbol table.
(mips_find_saved_regs): Use in_prologue() to avoid costly
prologue examination if possible.
(mips_skip_prologue): Use after_prologue() if possible to avoid
costly prologue examination.

* minsyms.c (lookup_solib_trampoline_symbol_by_pc,
find_solib_trampoline_target): New functions for handling
stepping into -g compiled shared libraries.
* symtab.h (lookup_solib_trampoline_symbol_by_pc,
find_solib_trampoline_target): Add prototypes.
* config/tm-sunos.h (IN_SOLIB_TRAMPOLINE, SKIP_TRAMPOLINE_CODE):
Define to handle stepping into -g compiled shared libraries.
* config/tm-sysv4.h (SKIP_TRAMPOLINE_CODE): Define to handle
stepping into -g compiled shared libraries.
* configure.in: Add mips-*-sysv4* support.
* config/mips/mipsv4.mh, config/mips/mipsv4.mt,
config/mips/tm-mipsv4.h, config/mips/xm-mipsv4.h, mipsv4-nat.c:
New files for MIPS SVR4 support.
* Makefile.in: Update for new mipsv4 files.
* alpha-tdep.c (heuristic_proc_desc, find_proc_desc): Use
read_next_frame_reg to obtain the frame relative stack pointer.
* mips-tdep.c (heuristic_proc_desc): Use read_next_frame_reg to
obtain the frame relative stack pointer.
* mdebugread.c (parse_partial_symbols, psymtab_to_symtab1):
Handle stStatic and stStaticProc symbols in stabs-in-ecoff output
by entering them into the minimal symbol table.
* printcmd.c (print_scalar_formatted): Do not try to unpack to
a long for float formats.
* solib.c: Include "elf/mips.h" only if DT_MIPS_RLD_MAP does not
get defined in <link.h>.
* solib.c (solib_add): Add shared library sections to the section
table of the target before adding the symbols.
* partial-stab.h: Relocate static and global functions.
* dbxread.c (read_dbx_symtab): Remove unused variable
end_of_text_address. Relocate text_addr when passing it
to end_psymtab.
For Alpha OSF/1 targets, enable gdb to set breakpoints in shared
library functions before the executable is run. Retrieve dynamic
symbols from stripped executables.
* mipsread.c (read_alphacoff_dynamic_symtab): New function.
* mipsread.c (mipscoff_symfile_read): Use it. Issue warning message
if no debugging symbols were found.
* alpha-tdep.c (alpha_skip_prologue): Silently return the unaltered
pc if memory at the pc is not accessible and GDB_TARGET_HAS_SHARED_LIBS
is defined.
* config/alpha/nm-alpha.h (GDB_TARGET_HAS_SHARED_LIBS): Define,
OSF/1 has shared libraries.
