You (AMD) manufacture a FP unit with 128 bit precision, but offer NO IEEE 754 basic math library routines for that precision, e.g. "amd_cosl".
Also, there is NO Win x32 library. Huh? 128 bit FP precision works just as well on x32 as x64.
I believe that you must mean 80-bit long double support, as I am not aware of any x86 hardware that does true 128-bit floating point operations. For example, SSE registers are 128-bits wide, but they are packed either with 4 32-bit single precision numbers or 2 64-bit double precision numbers. AVX makes this even wider.
I assume that you have already looked at the AMD LibM library available for download here:
The functions contained therein are what we have implemented and support.
Sorry, yes, 80. Why not provide an implementation of that (long double)?
This simple test:
I don't have an answer for you; I am sure its a combination of available resources and perceived demand. If our library does not meet your needs, maybe you could evaluate other libraries such as those that ship with the native compilers, or use available packages such as the GSL or the GMP.
