create_dyld_chained_fixup_cmd

LIEF::result<bool> LIEF::dsc::Dylib::extract_opt_t::create_dyld_chained_fixup_cmd

Whether the LC_DYLD_CHAINED_FIXUPS command should be (re)created.

If this value is not set, LIEF will add the command only if it's meaningful regarding the other options

fix_branches

bool LIEF::dsc::Dylib::extract_opt_t::fix_branches = false

Fix call instructions that target addresses outside the current dylib virtual space.

Warning

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism: LIEF::dsc::enable_cache or LIEF::dsc::DyldSharedCache::enable_caching

fix_memory

bool LIEF::dsc::Dylib::extract_opt_t::fix_memory = false

Fix memory accesses performed outside the dylib's virtual space.

Warning

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism: LIEF::dsc::enable_cache or LIEF::dsc::DyldSharedCache::enable_caching

fix_objc

bool LIEF::dsc::Dylib::extract_opt_t::fix_objc = false

Fix Objective-C information.

fix_relocations

bool LIEF::dsc::Dylib::extract_opt_t::fix_relocations = false

Recover and fix relocations.

Warning

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism: LIEF::dsc::enable_cache or LIEF::dsc::DyldSharedCache::enable_caching

pack

bool LIEF::dsc::Dylib::extract_opt_t::pack = true

Whether the segment's offsets should be packed to avoid an in-memory size while writing back the binary.

Note

This option does not have an impact on the performances
