Code Generation Options

The code generation options let you specify how code should be generated.

Descriptions of Code Generation Options

-[no]recursive

Default: -norecursive

Compiles all procedures (functions and subroutines) for possible recursive execution. When -recursive is specified, the -auto option is also set.

-[no]reentrancy [keyword]

Default: -noreentrancy

Generates reentrant code that supports a multithreaded application. The keyword can be:

• none  Same as -noreentrancy. Tells the Intel Fortran run-time library (RTL) that the program will not be relying on threaded or asynchronous reentrancy. Therefore, the RTL will not guard against such interrupts inside its own critical regions.

• async
  Tells the RTL that the program may contain asynchronous handlers that could call the RTL. This causes the RTL to guard against asynchronous interrupts inside its own critical regions.

• threaded
  Tells the RTL that the program is multithreaded. This causes the RTL to use thread locking to guard its own critical regions.
  Specifying -threads sets -reentrancy threaded, since multithreaded code must be reentrant.
  Specifying -reentrancy is equivalent to specifying -reentrancy threaded.

-sox[-] (IA-32 systems only)

Default: -sox-

Enables saving of the compiler options and version in the executable.

This option has no effect in Itanium®-based systems.
