We are looking forward to accepting and releasing this change. -- Liubov Dmitrieva ---------- Forwarded message ---------- From: Dmitrieva Liubov <liubov.dmitrieva@gmail.com> Date: 2012/4/5 Subject: Re: PATCH: optimized expf for x86_32 To: Ulrich Drepper <drepper@gmail.com> Копия: "H.J. Lu" <hjl.tools@gmail.com>, libc-alpha@sourceware.org Hello, Code was replaced to sysdeps/i386/i686/multiarch. New patch is attached. My performance data was about { expf (which uses __ieee754_expf), __ieee754_expf } not about { __expf_finite, __ieee754_expf }. Sorry for misprint in names at my previous letter. We didn't check __expf_finite but believe it becomes faster as well. Change Log: 2012-04-05 Liubov Dmitrieva <liubov.dmitrieva@gmail.com> * sysdeps/i386/i686/multiarch/Makefile: Add (libm-sysdep_routines): e_expf-sse2 e_expf_finite.sse2 init-arch * sysdeps/i386/i686/multiarch/e_expf.S: New file. * sysdeps/i386/i686/multiarch/e_expf-sse2.S: New file. * sysdeps/i386/i686/multiarch/e_expf_finite-sse2.S: New file. -- Liubov Dmitrieva Intel Corporation 2012/4/3 Ulrich Drepper <drepper@gmail.com>: > On Mon, Apr 2, 2012 at 10:43, H.J.
