gcc Function Attributes

This version of the Intel® C++ Compiler supports the following gcc function attributes:

• noinline - prevents a function from being inlined
• always_inline - inlines the function even if no optimization is specified
• used - code must be emitted for the function even if the function is not referenced

Example

int round_sqrt(int) __attribute__ ((always_inline));

In this example, the function round_sqrt() is inlined even if no optimization is specified.
