[Barrelfish-users] newlib and accelerated math on Intel64?

[Simon Peter]

Hi,

Do we know whether newlib supports hardware accelerated math on the 
Intel64 platform? When Barrelfish is compiled for x86_64, I can see that 
math-using applications link software math routines.

In the newlib source directory (and also in the upstream distribution), 
I can spot only an i387 directory for accelerated math. I assume this 
only works on IA-32, but not on Intel64?

I recall that Sun's math library---which we used prior to newlib---had 
Intel64 math acceleration, but we had to remove it due to licensing 
constraints.
