This structure is used to tweak the extraction process while calling Dylib::get_with_opt. These options allow to deoptimize the dylib and get an accurate representation of the origin Mach-O binary.

Fields

pack: bool

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

This option does not have an impact on the performances

fix_branches: bool

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

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism.

crate::dsc::enable_cache or crate::dsc::DyldSharedCache::enable_caching

fix_memory: bool

Fix memory accesses performed outside the dylib’s virtual space

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism.

crate::dsc::enable_cache or crate::dsc::DyldSharedCache::enable_caching

fix_relocations: bool

Recover and fix relocations

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism.

crate::dsc::enable_cache or crate::dsc::DyldSharedCache::enable_caching

fix_objc: bool

Fix Objective-C information

Enabling this option can have a significant impact on the performances. Make sure to enable the internal cache mechanism.

crate::dsc::enable_cache or crate::dsc::DyldSharedCache::enable_caching

create_dyld_chained_fixup_cmd: Option<bool>

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
