Hi Linaro Toochain Group, I have few questions on glibc+libm w.r.t aarch64. If possible, please provide some insight, otherwise kindly redirect me to the concerned person/forum.
1.It seems from the community patches that ARM/Linaro is optimizing glibc functions such as memcpy/memmove, string for aarch64. However, looks like some of these (e.g. memcpy/memmov) patches are still not merged in glibc. Any comment on their availability in glibc? e.g. https://www.sourceware.org/ml/libc-alpha/2015-12/msg00341.html 2. On the same note, is there any plan for optimizing/tuning libm functions (e.g. trigonometric) for aarch64? I could find any matching patches on review board. Please correct me if I am wrong. 3. Looks like ARM have released an independent version of libm for certain trigonometric functions. https://github.com/ARM-software/optimized-routines. Any plan of these optimization going in glibc's libm? Any comment on its performance improvement over GNU libm ? Thanks in advance for your time. -- with regards, Virendra Kumar Pathak
