1This directory contains code for AMD bulldozer including its piledriver update. 2 3We currently make limited use of SIMD instructions, both via the MPN_PATH and 4via inclusion of x86_64/fastsse files. 5 6The bd1 cores share one SIMD/FPU pipeline for two integer units. This probably 7means that an all-core GMP load (such as a HPC load) might run slower if there 8is significant SIMD dependency. 9 10We should perhaps allow a special 'bd1nosimd' pseudo cpu-name excluding any 11SIMD code. 12
