"GCC supports built-in functions for math.h and complex.h functions in
the C99/C11 standards (both folding calls for constant arguments, and
expanding inline when the processor supports appropriate
functionality). More such functions have been added in ISO/IEC TS
18661, supporting features of IEEE 754-2008. It would be useful to
have built-in functions for those, both folding for constant
arguments, and expanding inline where appropriate (e.g. for roundeven
and the functions rounding result to narrower type, on some
processors; roundeven can be inlined on x86 for SSE4.1 and later, and
the narrowing functions on IA64 and POWER8, for example)".

The above Project Idea is made available on 'Summer of Code' wiki of
GNU GCC Website. I wanted to have some more details about above idea
regarding to what is expected for implementation and expected output
for the same.
