Tulio Magno Quites Machado Filho c064f6a613 powerpc: Fix logbl on power7 [BZ# 21280] ... 1. Fix the results for negative subnormals by ignoring the signal when normalizing the value. 2. Fix the output when the high part is a power of 2 and the low part is a nonzero number with opposite sign. This fix is based on commit 380bd0fd24. After applying this patch, logbl() tests pass cleanly on POWER >= 7. Tested on powerpc, powerpc64 and powerpc64le [BZ #21280] * sysdeps/powerpc/power7/fpu/s_logbl.c (__logbl): Ignore the signal of subnormals and adjust the exponent of power of 2 down when low part has opposite sign.		2017-04-28 19:45:52 -03:00
