    powerpc64: add single-instruction math functions · 94f74419
    Rich Felker 提交于
    while the official elfv2 abi for "powerpc64le" sets power8 as the
    baseline isa, we use it for both little and big endian powerpc64
    targets and need to maintain compatibility with pre-power8 models. the
    instructions for sqrt, fabs, and fma are in the baseline isa; support
    for the rest is conditional via predefined isa-level macros.
