This directory contains code for AMD bulldozer including its piledriver update.
We currently make limited use of SIMD instructions, both via the MPN_PATH and
via inclusion of x86_64/fastsse files.
The bd1 cores share one SIMD/FPU pipeline for two integer units. This probably
means that an all-core GMP load (such as a HPC load) might run slower if there
is significant SIMD dependency.
We should perhaps allow a special 'bd1nosimd' pseudo cpu-name excluding any
SIMD code.
