Tells the compiler to prepare a routine for hotpatching.
- An integer specifying the number of bytes the compiler should add before the function entry point.
- The compiler does not prepare routines for hotpatching.
This option tells the compiler to prepare a routine for hotpatching. The compiler inserts nop padding around function entry points so that the resulting image is hot patchable.
Specifically, the compiler adds nop bytes after each function entry point and enough nop bytes before the function entry point to fit a direct jump instruction on the target architecture.
nis specified, it overrides the default number of bytes that the compiler adds before the function entry point.
