H A Dfpu_explode.cdiff 35f612b88a981f2ff8d1935e484587d448a62cb1 Sun Feb 22 22:40:27 CET 2015 Nathan Whitehorn <nwhitehorn@FreeBSD.org> Kernel support for the Vector-Scalar eXtension (VSX) found on the POWER7
and POWER8. This instruction set unifies the 32 64-bit scalar floating
point registers with the 32 128-bit vector registers into a single bank
of 64 128-bit registers. Kernel support mostly amounts to saving and
restoring the wider version of the floating point registers and making
sure that both scalar FP and vector registers are enabled once a VSX
instruction is executed. get_mcontext() and friends currently cannot
see the high bits, which will require a little more work.

As the system compiler (GCC 4.2) does not support VSX, making use of this
from userland requires either newer GCC or clang.
