/* For SVR4 shared libraries, each call to a library routine goes through
a small piece of trampoline code in the ".plt" section.
The horribly ugly wait_for_inferior() routine uses this macro to detect
when we have stepped into one of these fragments.
We do not use lookup_solib_trampoline_symbol_by_pc, because
we cannot always find the shared library trampoline symbols
(e.g. on Irix5). */

* config/i386/nm-linux.h: Enable prototypes that were #ifdef out. * config/tm-sysv4.h (in_plt_section): Add prototype. * maint.c (maintenance_translate_address): Avoid assignment inside if, per GNU coding standards. * symfile.c (simple_read_overlay_table): Avoid assignments inside if, per GNU coding standards. * monitor.c (parse_register_dump): Is really a void function. Add prototype. (monitor_read_memory): Remove unused variable "name". (monitor_read_memory): Remove unused variable "regbuf". (monitor_open): Remove unused variable "i". (get_hex_word): Apparently unused, #if away for now. (from_hex): Ditto. * i386v4-nat.c (supply_fpregset): Remove unused variable "regi". (fill_fpregset): Remove unused variables "regi", "to", "from" and "registers". * remote-e7000.c (ctype.h): Include. (e7000_insert_breakpoint): #if away unused arg used by unused expr. * frame.h (generic_get_saved_register): Add prototype. (enum lval_type): Add partial forward decl. * dsrec.c (make_srec): Remove unused variable "type_code". * remote-sim.c (gdbsim_wait): Handle sim_running and sim_polling cases by just ignoring them. (command.h): Include. * java-exp.y (parse_number): Remove unused variable "unsigned_p". * java-lang.c (gdbcore.h): Include for prototypes. (type_from_class): Remove unused variable "ftype". (type_from_class): Remove unused variable "name_length".

(simple_free_overlay_region_table): Ditto. (overlay_is_mapped): Add default case to switch. (simple_read_overlay_region_table): Ditto. (simple_read_overlay_region_table): Add prototype. * symtab.c (fixup_symbol_section): Remove unused msym variable. (fixup_psymbol_section): Ditto. (find_pc_sect_symtab): Make distance a CORE_ADDR. * utils.c: Add comment about t_addr being either unsigned long or unsigned long long. (paddr): Change formats to match actual types args are cast to. (preg): Ditto. (paddr_nz): Ditto. (preg_nz): Ditto.

stashing it in the debugging information as part of the name of an
invented symbol ("gcc_cplus_marker$" for example). */
