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

GDB one of these days. :-)

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).

after the prologue. Uses PDRs and the symbol table.

costly prologue examination.

is defined.
* config/alpha/nm-alpha.h (GDB_TARGET_HAS_SHARED_LIBS): Define,
OSF/1 has shared libraries.
partial_symbol): Shrink the storage sizes of symbols, by making
enums into 1-byte bitfields when compiled __GNUC__, moving all the
enums and small ints to the end of each struct to improve
alignment, and switching the section number from int to unsigned short.

* coffread.c: Tell end_symtab to sort the line table.

coff_end_symtab and coff_add_symbol_to_list.

not a "struct coff_pending".
