u64 map__objdump_2mem	(	struct map *	map,

map__objdump_2mem - convert objdump address to a memory address. : memory map : objdump address

Closely related to map__rip_2objdump(), this function takes an address from objdump and converts it to a memory address. Note this assumes that contains the address. To be sure the result is valid, check it forwards e.g. map__rip_2objdump(map->map_ip(map, map__objdump_2mem(map, ip))) == ip

Return: Memory address.

map__rip_2objdump - convert symbol start address to objdump address. : memory map : symbol start address

objdump wants/reports absolute IPs for ET_EXEC, and RIPs for ET_DYN. map->dso->adjust_symbols==1 for ET_EXEC-like cases except ET_REL which is relative to section start.

Return: Address suitable for passing to "objdump --start-address="
