Custom ld64 wrapper for macOS
|
||||
|
||||
This script wraps the standard macOS linker (/usr/bin/ld) to modify executable memory
|
||||
protection flags in the resulting Mach-O binary. It works in three stages:
|
||||
|
||||
1. First, it passes through all arguments to the regular macOS linker to create the binary
|
||||
2. Then, it parses command line arguments to identify output file and segment protection flags
|
||||
3. Finally, it modifies the output binary's Mach-O headers to ensure segments (particularly __TEXT)
|
||||
have the maximum protection flags (rwx) we specify, even if the default macOS linker would restrict them
|
||||
|
||||
This is necessary because macOS restricts writable+executable memory by default,
|
||||
but certain applications need this capability for dynamic code generation or JIT compilation.
|
||||
|
||||
Usage: Same as the standard ld64 linker, with the added benefit that -segprot options
|
||||
will have their max_prot values properly preserved in the output binary.
