This enum describes the different ways to relocate the segments table.

Members:

AUTO

Defer the choice of the layout to LIEF.

PIE_SHIFT

The content of the binary right after the segments table is shifted and the relocations are updated accordingly. This kind of shift only works with PIE binaries.

BSS_END

The new segments table is relocated right after the first bss-like segments.

FILE_END

The new segments table is relocated at the end of the binary.

SEGMENT_GAP

The new segments table is relocated between two LOAD segments. This kind of relocation is only doable when there is an alignment enforcement.
