Except for the two m32r modules, this checkin is for overlay support. * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), find_pc_sect_function(), find_pc_sect_partial_function(): new functions for debugging overlays; pc without section is ambiguous. * breakpoint.[ch]: add section pointer to breakpoint struct; add section argument to check_duplicates(); check section as well as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(), breakpoint_thread_match(), bpstat_stop_status()]; add section argument to describe_other_breakpoints(); use INIT_SAL() macro to zero-out new sal structures; make resolve_sal_pc() fix up the sal's section as well as its pc; match on section + pc in clear_command() and delete_breakpoint(); account for overlay sections in insert_breakpoints(), remove_breakpoint() and breakpoint_re_set_one(); all this to support overlays where a PC is not unique. * exec.c: change xfer_memory() to handle overlay sections. * findvar.c: change read_var_value() to handle overlay sections. * frame.h: declaration for block_for_pc_sect() [blockframe.c]. * infcmd.c: jump_command() warns against jumping into an overlay that's not in memory. Also use INIT_SAL() to initialize sals. * infrun.c: wait_for_inferior() sets a flag to invalidate cached overlay state information; Also use INIT_SAL() to init sals. * m32r-rom.c: modify load routines to use LMA instead of VMA. * m32r-stub.c: mask exit value down to 8 bits; screen out any memory read/writes in the range 600000 to a00000, and ff680000 to ff800000 (hangs because nothing is mapped there); fix strcpy(). * maint.c: maintenance command "translate-address" supports overlays. * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays. * objfiles.[ch]: add ovly_mapped field to the obj_section struct; this constitutes gdb's internal overlay mapping table. Add macro ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays. Add function find_pc_sect_section(). * printcmd.c: modify print_address_symbolic() with overlay smarts; modify address_info() with overlay smarts; add function sym_info() to support the INFO SYMBOL command (translate address to symbol(s)); modify disassemble_command() to work on unmapped overlays. * source.c: use INIT_SAL() to initialize sals. * symfile.[ch]: change generic_load() to use section's LMA address instead of VMA address, for overlay sections. Add numerous functions for finding a PC's section / overlay, translating between VMA and LMA address ranges, determining if an overlay section is mapped, etc. Add several user commands for overlay debugging. Add support for a "generic" form of automatically reading overlay mapping info from the inferior (based on the default (simple) overlay manager which Cygnus provides as an example). * symtab.[ch]: add functions find_pc_sect_symtab(), find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line() for lookup; modify lookup_symbol and decode_line_1() to use them; modify find_function_start_sal() to account for overlay sections; add macro INIT_SAL() for initializing struct symtab_and_line. * target.c: fix a comment in the declaration of target_ops.
