This representation is called an Abstract Syntax Tree (AST). Up to this point ifort and ifx are identical. Now, the AST has to be translated or "lowered" to an intermediate representation (IR) to continue with the process of going from your source to machine code. For ifor...

In C, array syntax asserts to the compiler that there is no backward dependence between data elements on the right hand side and data elements on the left hand side that would make vectorization unsafe. In the example above, no backward dependence would imply that m³0 and no overlap betwe...
This reference section describes the syntax and operation of each compiler option. For easy reference, the options are arranged in alphabetical order. For an overview and tips on options usage and which options are best for which tasks, refer to the 'Using Command-line Options' section of the...
