Support lexical blocks and function bodies that occupy
non-contiguous address ranges. * addrmap.c, addrmap.h: New files. * 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. * buildsym.c: #include "addrmap.h" (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. * dwarf2read.c (dwarf2_record_block_ranges): New function. (read_func_scope, read_lexical_block_scope): Call it. * Makefile.in (SFILES): Add addrmap.c. (addrmap_h): New header dependency variable. (COMMON_OBS): Add addrmap.o. (addrmap.o): New rule.l (block.o, objfiles.o, buildsym.o): Depend on $(addrmap_h). * block.c (blockvector_for_pc, blockvector_for_pc_sect): Return a pointer to the block, not its index in the blockvector. (block_for_pc_sect): Use the returned block, instead of looking it up ourselves. * block.h (blockvector_for_pc, blockvector_for_pc_sect): Update declarations. * breakpoint.c (resolve_sal_pc): Use returned block, instead of looking it up ourselves. * stack.c (print_frame_label_vars): Disable function, which depends on the block's index. * buildsym.c (finish_block): Return the block we've built. * buildsym.h (finish_block): Update prototype. * defs.h (CORE_ADDR_MAX): New constant.
