Ryan Houdek	0fbb6aa02f	cephes: Rewrite to use softfloat-3e 128-bit And also use it at the same time, since the function signatures changed. Instead of relying on the host libc math libraries for `long double` ALU operations, rewrite the entire thing to use softfloat-3e fixed width float128_t types. This is a very invasive change in cephes but is a necessary requirement for getting the precision we require in environments that map `long double` to be the same as `double`, like Win32 and MacOS. This fixes the precision issue in transcendental operations when running under WINE.	2025-04-07 15:13:04 -07:00

cephes: Rewrite to use softfloat-3e 128-bit

And also use it at the same time, since the function signatures changed.

Instead of relying on the host libc math libraries for `long double` ALU
operations, rewrite the entire thing to use softfloat-3e fixed width
float128_t types.

This is a very invasive change in cephes but is a necessary requirement
for getting the precision we require in environments that map `long
  double` to be the same as `double`, like Win32 and MacOS.

This fixes the precision issue in transcendental operations when running
under WINE.

FEXCore/Common: Adds cephes math library

Only the few transcendental functions that FEX needs.
Disabled when building on x86-64.
