the another_trap field to stepping_over_breakpoint.

field to stepping_over_breakpoint.

(restore_inferior_status, prepare_to_proceed): Adjust.
* gdbthread.h (struct thread_info): Rename the
trap_expected field to stepping_over_breakpoint.

Adjust.

* block.h (struct addrmap): New forward declaration.
(struct blockvector): New member, 'map'.
(BLOCKVECTOR_MAP): New accessor macro.
* block.c: #include "addrmap.h"
(blockvector_for_pc_sect): If the blockvector we've found has
an address map, use it instead of searching the blocks.

(pending_addrmap_obstack, pending_addrmap_interesting): New static
variables.
(really_free_pendings): If we have a pending addrmap, free it too.
(record_block_range): New function.
(make_blockvector): If we have an interesting pending addrmap,
record it in the new blockvector.
(start_symtab, buildsym_init): Assert that there is no pending
addrmap now; we should have cleaned up any addrmaps we'd built
previously.
(end_symtab): If there is a pending addrmap left over that didn't
get included in the blockvector, free it.
* buildsym.h (struct addrmap): New forward declaration.
(record_block_range): New prototype.
* objfiles.c: #include "addrmap.h".
(objfile_relocate): Relocate the blockvector's address map, if
present.
