* | powerpc: Fix logbl on power7 [BZ# 21280] | Tulio Magno Quites Machado Filho | 2017-04-28 | 1 | -6/+18 |
| | | | | | | | | | | | | | | | | | 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 380bd0fd2418f8988217de950f8b8ff18af0cb2b. 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. | ||||

* | Fix POWER7 logb results for negative subnormals (bug 19375) | Adhemerval Zanella | 2015-12-17 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | The optimized POWER7 logb implementation does not use the absolute value of the word extracted from the input to apply the leading 0-bits builtin (to ignore the float sign). This patch fixes it by clearing the signal bit in the resulting word. It fixes the subnormal tests failures when running on POWER7 ou newer chip. Tested on powerpc64le (POWER8).
