List of Compiler Options and Their Defaults
| Option Type | Default Value | #pragma options | C | C++ |
| -qoption | nohsflt | HSFLT | x | x |
Syntax:
-qhsflt | -qnohsflt
HSFLT | NOHSFLT
Purpose
Speeds up calculations by removing range checking on
single-precision float results, and on
conversions from floating point to integer. -qnohsflt
specifies that single-precision expressions are rounded after
expression evaluation, and that floating-point-to-integer
conversions are to be checked for out of range values.
Notes
This option is obsolete. Use -qfloat=hsflt
in your new applications.
The hsflt option overrides the rndsngl and spnans options.
The -qhsflt option is intended for specific applications in which floating-point computations have known characteristics. Using this option when compiling other application programs can produce incorrect results without warning. See RISC System/6000 Floating Point Hardware before you use the -qhslft option.
