rrm

Syntax

    -qrrm | -qnorrm 
    RRM | NORRM 

Purpose
Prevents floating-point optimizations that are incompatible with run-time rounding to plus and minus infinity modes.

Notes
This option informs the compiler that, at run time, the floating-point rounding mode may change or that the mode is not set to -yn (rounding to the nearest representable number.)

-qrrm must also be specified if the Floating Point Status and Control register is changed at run time.

The default, -qnorrm, generates code that is compatible with run-time rounding modes nearest and zero. For a list of rounding mode options, see the y compiler option.

This option is obsolete. Use -qfloat=rrm in your new applications.
