Description

Option() allows the programmer to specify additional attributes or characteristics. Enclosing the string into quotes and parentheses is required in the syntax. Unrecognized options are ignored.

Option can also be used as a statement to specify other compile time options. See Compiler Switches.

Individual options are explained below.

SSE

Option("SSE") indicates that a floating point value (Single or Double) returned from a function is stored in the xmm0 register. Option("SSE") is ignored unless the source is compiled with the -fpu SSE command line option. This option may be used immediately after the return type in a function declaration or function definition. This option is an optimization only and not required to compile programs using the -fpu SSE command line option.

start GeSHi

Declare Function ValueInXmm0 () As Double Option("sse")

end GeSHi

FPU

Option("FPU") indicates that a floating point value (Single or Double) returned from a function is stored in the st(0) register. This option may be used immediately after the return type in a function declaration or function definition.

start GeSHi

Declare Function ValueInStZero () As Double Option("fpu")

end GeSHi
