This patch fixes bug 16386, ldbl-128ibm logl inaccuracy (with consequent inaccuracy for lgammal) for arguments where the high double is subnormal, which showed up while attempting to regenerate ulps for powerpc-nofpu for 2.19. The problem here is logic failing to allow for subnormals when calculating the exponent of the argument. Tested for powerpc-nofpu. * sysdeps/ieee754/ldbl-128ibm/e_logl.c (__ieee754_logl): Adjust numbers with subnormal high part when calculating exponent. ----------------------------------------------------------------------- Summary of changes: ChangeLog | 4 ++++ NEWS | 3 ++- sysdeps/ieee754/ldbl-128ibm/e_logl.c | 8 ++++++++ 3 files changed, 14 insertions(+), 1 deletions(-) -- You are receiving this mail because: You are on the CC list for the bug.
