1 1.1 mrg This directory contains code for AMD bulldozer including its piledriver update. 2 1.1 mrg 3 1.1 mrg We currently make limited use of SIMD instructions, both via the MPN_PATH and 4 1.1 mrg via inclusion of x86_64/fastsse files. 5 1.1 mrg 6 1.1 mrg The bd1 cores share one SIMD/FPU pipeline for two integer units. This probably 7 1.1 mrg means that an all-core GMP load (such as a HPC load) might run slower if there 8 1.1 mrg is significant SIMD dependency. 9 1.1 mrg 10 1.1 mrg We should perhaps allow a special 'bd1nosimd' pseudo cpu-name excluding any 11 1.1 mrg SIMD code. 12
