Hi,

Thomas has pointed out that WinUAE[1] has an updated softfloat library
implementing missing operations for 680x0.

Do you think these changes can be merged in QEMU?

Thanks,
Laurent

From the licensing point of view, they seems to use the SoftFloat-2a
license, so that should be fine.

Personally I am fine adding general trigonometric functions to
softfloat, that might help other targets like x86 which uses  the math
functions from libm and thus have different behaviour/precision
depending on the host.

The question is more how m68k specific are those trigonometric
functions. If we can have a way to implement them as generic
trigonometric functions reusable by other targets, I am all for it. If
not that code would probably be better in target/m68k.
