hotpatch
Tells the compiler to prepare a routine for hotpatching. This feature is only available for ifort.
Syntax
Linux: |
-hotpatch[=n] |
macOS: |
None |
Windows: |
/hotpatch[:n] |
Arguments
n |
An integer specifying the number of bytes the compiler should add before the function entry point. |
Default
OFF |
The compiler does not prepare routines for hotpatching. |
Description
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.
If n is specified, it overrides the default number of bytes that the compiler adds before the function entry point.
