* Add libm_alias_finite for _finite symbolsWilco Dijkstra2020-01-032-19/+17
| | | | | | | | | | | | | | | | | | | This patch adds a new macro, libm_alias_finite, to define all _finite symbol. It sets all _finite symbol as compat symbol based on its first version (obtained from the definition at built generated first-versions.h). The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need special treatment in code that is shared between long double and float128. It is done by adding a list, similar to internal symbol redifinition, on sysdeps/ieee754/float128/float128_private.h. Alpha also needs some tricky changes to ensure we still emit 2 compat symbols for sqrt(f). Passes buildmanyglibc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined.

* Remove alpha math_private.h.Joseph Myers2018-09-051-18/+0
| | | | | | | | | | | | | | | After some math_private.h cleanups (in particulat math-barriers.h being split out), the only thing left in the alpha math_private.h was macro definitions of __isnan and __isnanf, apparently (based on the comments) intended to avoid problems with inline definitions in other math_private.h files. Those inline definitions were removed in commit fe8c2b33aed067282ecac0cc3fdff1feef88548b, and the alpha math_private.h is no longer needed; this patch removes it. Tested with build-many-glibcs.py that installed stripped shared libraries for alpha are unchanged by the patch. * sysdeps/alpha/fpu/math_private.h: Remove.
* Move math_opt_barrier, math_force_eval to separate math-barriers.h.Joseph Myers2018-05-092-6/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues cleaning up math_private.h by moving the math_opt_barrier and math_force_eval macros to a separate header math-barriers.h. At present, those macros are inside a "#ifndef math_opt_barrier" in math_private.h to allow architectures to override them and then use a separate math-barriers.h header, no such #ifndef or #include_next is needed; architectures just have their own alternative version of math-barriers.h when providing their own optimized versions that avoid going through memory unnecessarily. The generic math-barriers.h has a comment added to document these two macros. In this patch, math_private.h is made to #include <math-barriers.h>, so files using these macros do not need updating yet. That is because of uses of math_force_eval in math_check_force_underflow and math_check_force_underflow_nonneg, which are still defined in math_private.h. Once those are moved out to a separate header, that separate header can be made to include <math-barriers.h>, as can the other files directly using these barrier macros, and then the include of <math-barriers.h> from math_private.h can be removed. Tested for x86_64 and x86. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/math-barriers.h: New file. * sysdeps/generic/math_private.h [!math_opt_barrier] (math_opt_barrier): Move to math-barriers.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in libc-alpha [1], alpha trunc{f} implementation uses addt/suc and subt/suc and although the Alpha Architecture Handbook version 3 states that that ADDx SUBx OUTPUT Exceptions (B.3 Mapping to IEEE Standard) should not generate Inexact if INE bit is set, the Alpha 21264 [2] chip manual (A.8 IEEE Floating-Point Conformance) states that ADDx SUBx OUTPUT does generate inexact exception for inexact result regardless. As Joseph noted [3] 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.

* Remove alpha specific fmax, fmin to fix sNaN handling [BZ #22660]Aurelien Jarno2018-01-024-106/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Various fmax and fmin function implementations mishandle sNaN arguments: (a) When both arguments are NaNs, the return value should be a qNaN, but sometimes it is an sNaN if at least one argument is an sNaN. (b) Under TS 18661-1 semantics, if either argument is an sNaN then the result should be a qNaN (whereas if one argument is a qNaN and the other is not a NaN, the result should be the non-NaN argument). Various implementations treat sNaNs like qNaNs here. One way to fix that is to detect the sNaN and add a special case. That said there is no FPU instruction to do that, so it requires transfering the FP value to an integer register and testing bits. This becomes quite complicated so it's probably better to just use the generic versions of these functions which just do that through issignaling.

Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

This patch series implements those interfaces for glibc. This first patch adds the architecture-independent pieces, the x86 and x86_64 implementations, and the <bits/fenv.h> and ABI baseline updates for all architectures so glibc keeps building and passing the ABI tests on all architectures. Subsequent patches add the fegetmode and fesetmode implementations for other architectures. femode_t is generally an integer type - the same type as fenv_t, or as the single element of fenv_t where fenv_t is a structure containing a single integer (or the single relevant element, where it has elements for both status and control registers) - except where architecture properties or consistency with the fenv_t implementation indicate otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic pointer value (-1 cast to const femode_t *), a value that can be distinguished from valid pointers by its high bits but otherwise contains a representation of the desired register contents, or a pointer to a constant variable (the powerpc case; __fe_dfl_mode is added as an exported constant object, an alias to __fe_dfl_env). Note that where architectures (that share a register between control and status bits) gain definitions of new floating-point control or status bits in future, the implementations of fesetmode for those architectures may need updating (depending on whether the new bits are control or status bits and what the implementation does with previously unknown bits), just like existing implementations of <fenv.h> functions that take care not to touch reserved bits may need updating when the set of reserved bits changes. (As any new bits are outside the scope of ISO C, that's just a quality-of-implementation issue for supporting them, not a conformance issue.) As with fenv_t, femode_t should properly include any software DFP rounding mode (and for both fenv_t and femode_t I'd consider that fragment of DFP support appropriate for inclusion in glibc even in the absence of the rest of libdfp; hardware DFP rounding modes should already be included if the definitions of which bits are status / control bits are correct). Tested for x86_64, x86, mips64 (hard float, and soft float to test the fallback version), arm (hard float) and powerpc (hard float, soft float and e500).
