65 translating between VMA and LMA address ranges, determining if an
66 overlay section is mapped, etc. Add several user commands for
67 overlay debugging. Add support for a "generic" form of automatically
68 reading overlay mapping info from the inferior (based on the default
69 (simple) overlay manager which Cygnus provides as an example).
70 * symtab.[ch]: add functions find_pc_sect_symtab(),
71 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
72 for lookup; modify lookup_symbol and decode_line_1() to use them;
73 modify find_function_start_sal() to account for overlay sections;
