GCC aligns global data to 16 bytes if their size is >= 16 bytes. This patch changes the exp_data struct slightly so that the fields are better aligned and without gaps. As a result on targets that support them, more load-pair instructions are used in exp. Exp10 is improved by moving invlog10_2N later so that neglog10_2hiN and neglog10_2loN can be loaded using load-pair. The exp benchmark improves 2.5%, "144bits" by 7.2%, "768bits" by 12.7% on Neoverse V2. Exp10 improves by 1.5%. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> |
