aarch64-none : TR1 Math floating point functions

[Mahesh Bodapati <maheshbodapati90 at gmail dot com>]

Hi,



I got errors when I tried to use std::remainder and std::round for
aarch64-none target and the the same test case is working for arm-none..



*#include <iostream>*

*#include <cmath>*

*#include <cfenv>*

*int main()*

*{*

*                float x=10,y=20,z;*

*                int a=10,b=15,c;*

*  z= std::remainder(x, y);   // Error : error: ‘remainder’ is not a member
of 'std'*

*    c= std::round(b); // error: 'round' is not a member of 'std'*

*    z= std::fmod(x, y);*

*  return (int)z;*

*}*



When I went through the newlib sources, these FP functions are defined only
if LDBL_EQ_DBL is set but for aarch64 this macro will not be set because of
different sizes of long double and double.

So these functions are not supported in aarch-none tool chain?



Thanking you in advance…



Thanks,
