* alpha: Remove s_ceil{f} and s_floor{f} implementation (BZ#22665)Adhemerval Zanella2018-01-041-51/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in libc-alpha [1], alpha ceil{f} and floor{f} implementation uses cvttq/svm and although the Alpha Architecture Handbook version 3 states that that CVTfi OUTPUT Exceptions (B.3 Mapping to IEEE Standard) should not generate Inexact if INE bit is set on fpcr, the Alpha 21264 [1] chip manual (A.8 IEEE Floating-Point Conformance) states that CVTfi and CVTif OUTPUT does generate inexact exception for inexact result regardless. As Joseph noted [2] to correctly fix it on alpha we need to either avoid the instruction or avoid any inexact bit from it being set on return from the function (while preserving the inexact bit that might be set on the entry to the function). The later will result mf_fpcr followed by a mt_fpcr to get and set the fpcr which will defeat the optimization itself. So the patch just remove the alpha optimized and rely on generic implementation. It fixes the math/test-*-{ceil,floor} on alpha.

* Use libm_alias_double for alpha.Joseph Myers2017-11-281-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes alpha libm function implementations use libm_alias_double to define function aliases. This also simplifies the code because the compatibility for long double = double is handled by libm_alias_double instead of locally in each source file. Tested with build-many-glibcs.py for alpha-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/alpha/fpu/s_ceil.c: Include <libm-alias-double.h>.

* alpha: fix floor on sNaN inputAurelien Jarno2016-08-021-4/+3
| | | | | | | | | | | | | | | The alpha version of floor wrongly return sNaN for sNaN input. Fix that by checking for NaN and by returning the input value added with itself in that case. Finally remove the code to handle inexact exception, floor should never generate such an exception. Changelog: * sysdeps/alpha/fpu/s_floor.c (__floor): Add argument with itself when it is a NaN. [_IEEE_FP_INEXACT] Remove. * sysdeps/alpha/fpu/s_floorf.c (__floorf): Likewise.
