From de800d83059dbedb7d151580f0a3bdc9eaf37340 Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Tue, 30 Jan 2018 14:48:22 +0000 Subject: Remove slow paths from exp Remove the __slowexp code, so exp is no longer correctly rounded. The result is computed to about 70 bits precision so the worst case ulp error is about 0.500007 in nearest rounding mode. * manual/probes.texi: Remove slowexp probes. * math/Makefile: Remove slowexp. * sysdeps/generic/math_private.h (__slowexp): Remove. * sysdeps/ieee754/dbl-64/e_exp.c (__ieee754_exp): Remove __slowexp and document error bounds. * sysdeps/i386/fpu/slowexp.c: Remove. * sysdeps/ia64/fpu/slowexp.c: Remove. * sysdeps/ieee754/dbl-64/slowexp.c: Remove. * sysdeps/ieee754/dbl-64/uexp.h (err_0): Remove. * sysdeps/m68k/m680x0/fpu/slowexp.c: Remove. * sysdeps/powerpc/power4/fpu/Makefile (CPPFLAGS-slowexp.c): Remove. * sysdeps/x86_64/fpu/multiarch/Makefile: Remove slowexp-fma. * sysdeps/x86_64/fpu/multiarch/e_exp-avx.c (__slowexp): Remove. * sysdeps/x86_64/fpu/multiarch/e_exp-fma.c (__slowexp): Remove. * sysdeps/x86_64/fpu/multiarch/e_exp-fma4.c (__slowexp): Remove. * sysdeps/x86_64/fpu/multiarch/slowexp-avx.c: Remove. * sysdeps/x86_64/fpu/multiarch/slowexp-fma.c: Remove. * sysdeps/x86_64/fpu/multiarch/slowexp-fma4.c: Remove. --- sysdeps/ia64/fpu/slowexp.c | 1 - 1 file changed, 1 deletion(-) delete mode 100644 sysdeps/ia64/fpu/slowexp.c (limited to 'sysdeps/ia64/fpu/slowexp.c') diff --git a/sysdeps/ia64/fpu/slowexp.c b/sysdeps/ia64/fpu/slowexp.c deleted file mode 100644 index 1cc8931700..0000000000 --- a/sysdeps/ia64/fpu/slowexp.c +++ /dev/null @@ -1 +0,0 @@ -/* Not needed. */ -- cgit 1.4.1
