From 024bcc5106a48307e2efc42ab85b3bbec6958163 Mon Sep 17 00:00:00 2001 From: Joseph Myers <joseph@codesourcery.com> Date: Wed, 8 Apr 2015 21:00:03 +0000 Subject: Add more tests of atan. This patch adds some randomly-generated tests of atan that are observed to increase ulps on x86_64. Tested for x86_64 and x86 and ulps updated accordingly. * math/auto-libm-test-in: Add more tests of atan. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise. --- math/auto-libm-test-in | 3 ++ math/auto-libm-test-out | 75 +++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 78 insertions(+) (limited
