示例1: region_statistics
Partitioner::RegionStats *
Partitioner::region_statistics()
{
MemoryMap mymap = *map;
mymap.prune(MemoryMap::MM_PROT_EXEC);
return region_statistics(mymap.va_extents());
}示例2: operator
// Obtain a memory map for disassembly
MemoryMap *disassembly_map(RSIM_Process *proc) {
MemoryMap *map = new MemoryMap(proc->get_memory(), MemoryMap::COPY_SHALLOW);
map->prune(MemoryMap::MM_PROT_READ); // don't let the disassembler read unreadable memory, else it will segfault
// Removes execute permission for any segment whose debug name does not contain the name of the executable. When
// comparing two different executables for clones, we probably don't need to compare code that came from dynamically
// linked libraries since they will be identical in both executables.
