https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218300 Bug ID: 218300 Summary: [LIBM] implementations of sincos, sincosf, and sincosl Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: standards Assignee: freebsd-standards@FreeBSD.org Reporter: sgk@troutmask.apl.washington.edu Created attachment 181395 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=181395&action=edit patch The attached patch implements sincos, sincosf, and sincosl. The primary benefit of these functions is that argument reduction is done once instead of twice in independent calls to sin() and cos(). * lib/msun/Makefile: . Add s_sincos[fl].c to the build. . Add sincos.3 documentation. . Add appropriate MLINKS. * lib/msun/Symbol.map: . Expose sincos[fl] symbols in dynamic libm.so. * lib/msun/man/sincos.3: . Documentation for sincos[fl]. * lib/msun/src/k_sincos.h: . Kernel for sincos() function. This merges the individual kernels for sin() and cos(). The merger offered an opportunity to re-arrange the individual kernels for better performance. * lib/msun/src/k_sincosf.h: . Kernel for sincosf() function. This merges the individual kernels for sinf() and cosf(). The merger offered an opportunity to re-arrange the individual kernels for better performance. * lib/msun/src/k_sincosl.h: . Kernel for sincosl() function. This merges the individual kernels for sinl() and cosl(). The merger offered an opportunity to re-arrange the individual kernels for better performance. * lib/msun/src/math.h: . Add prototytpes for sincos[fl](). * lib/msun/src/math_private.h: . Add RETURNV macros. This is needed to reset fpsetprec on I386 hardware for a function with type void. * lib/msun/src/s_sincos.c: . Implementation of sincos() where sin() and cos() were merged into one routine and possibly re-arranged for better performance. * lib/msun/src/s_sincosf.c: . Implementation of sincosf() where sinf() and cosf() were merged into one routine and possibly re-arranged for better performance. * lib/msun/src/s_sincosl.c: . Implementation of sincosl() where sinl() and cosl() were merged into one routine and possibly re-arranged for better performance. -- You are receiving this mail because: You are the assignee for the bug.home | help
