Floating-point and integer control
| Option name | Equivalent pragma name | Description |
|---|---|---|
| -qbitfields | None. | Specifies whether bit fields are signed or unsigned. |
| -qchars | #pragma options chars, #pragma chars | Determines whether all variables of type char is treated as signed or unsigned. |
| -qenum | #pragma options enum, #pragma enum | Specifies the amount of storage occupied by enumerations. |
| -qfloat | #pragma options float | Selects different strategies for speeding up or improving the accuracy of floating-point calculations. |
| -qldbl128, -qlongdouble | #pragma options ldbl128 | Increases the size of long double types from 64 bits to 128 bits. |
| -qlonglit | None. | In 64-bit mode, when determining the implicit types for integer literals, the compiler behaves as if an l or L suffix were added to integral literals with no suffix or with a suffix consisting only of u or U. |
| -qstrict | #pragma options [no]strict #pragma option_override (function_name, "opt (suboption_list)") |
Ensures that optimizations that are done by default at the -O3 and higher optimization levels, and, optionally at -O2, do not alter the semantics of a program. |
| -y | None. | Specifies the rounding mode for the compiler to use when evaluating constant floating-point expressions at compile time. |
