- Is one of the logical values "true" or "false".
- Is an optional list of one or more math library functions to which the attribute should be applied. If you specify more than one function, they must be separated with commas.Precision-specific variants like sin and sinf are considered different functions, so you would need to use-fimf-arch-consistency=true:sin,sinf(or/Qimf-arch-consistency:true:sin,sinf) to specify consistent results for both the single-precision and double-precision sine functions.You also can specify the symbol /f to denote single-precision divides, symbol / to denote double-precision divides, symbol /l to denote extended-precision divides, and symbol /q to denote quad-precision divides. For example you can specify-fimf-arch-consistency=true:/or/Qimf-arch-consistency:true:/.
- Implementations of some math library functions may produce slightly different results on implementations of the same architecture.
