*	Do not include math-barriers.h in math_private.h.	Joseph Myers	2018-05-11	1	-0/+1

No attempt is made to remove any math_private.h includes that are now unused, except in strtod_l.c where that is done to avoid line number changes in assertions, so that installed stripped shared libraries can be compared before and after the patch. (I think the floating-point environment support in math_private.h should also move out - some architectures already have fenv_private.h as an architecture-internal header included from their math_private.h - and after moving that out might be a better time to identify unused math_private.h includes.) Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/math_private.h: Do not include <math-barriers.h>. * stdlib/strtod_l.c: Include <math-barriers.h> instead of <math_private.h>. * math/fromfp.h: Include <math-barriers.h>. * math/math-narrow.h: Likewise. * math/s_nextafter.c: Likewise. * math/s_nexttowardf.c: Likewise. * sysdeps/aarch64/fpu/s_llrint.c: Likewise. * sysdeps/aarch64/fpu/s_llrintf.c: Likewise. * sysdeps/aarch64/fpu/s_lrint.c: Likewise. * sysdeps/aarch64/fpu/s_lrintf.c: Likewise. * sysdeps/i386/fpu/s_nextafterl.c: Likewise. * sysdeps/i386/fpu/s_nexttoward.c: Likewise. * sysdeps/i386/fpu/s_nexttowardf.c: Likewise. * sysdeps/ieee754/dbl-64/e_atan2.c: Likewise. * sysdeps/ieee754/dbl-64/e_atanh.c: Likewise. * sysdeps/ieee754/dbl-64/e_exp.c: Likewise. * sysdeps/ieee754/dbl-64/e_exp2.c: Likewise. * sysdeps/ieee754/dbl-64/e_j0.c: Likewise. * sysdeps/ieee754/dbl-64/e_sqrt.c: Likewise. * sysdeps/ieee754/dbl-64/s_expm1.c: Likewise. * sysdeps/ieee754/dbl-64/s_fma.c: Likewise. * sysdeps/ieee754/dbl-64/s_fmaf.c: Likewise. * sysdeps/ieee754/dbl-64/s_log1p.c: Likewise. * sysdeps/ieee754/dbl-64/s_nearbyint.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_nearbyint.c: Likewise. * sysdeps/ieee754/flt-32/e_atanhf.c: Likewise. * sysdeps/ieee754/flt-32/e_j0f.c: Likewise. * sysdeps/ieee754/flt-32/s_expm1f.c: Likewise. * sysdeps/ieee754/flt-32/s_log1pf.c: Likewise. * sysdeps/ieee754/flt-32/s_nearbyintf.c: Likewise. * sysdeps/ieee754/flt-32/s_nextafterf.c: Likewise. * sysdeps/ieee754/k_standardl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_asinl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_expl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_powl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nearbyintl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nextafterl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/e_asinl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_rintl.c: Likewise. * sysdeps/ieee754/ldbl-96/e_atanhl.c: Likewise. * sysdeps/ieee754/ldbl-96/e_j0l.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-96/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-96/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-opt/s_nexttowardfd.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nextafterl.c: Likewise.
*	Move math_check_force_underflow macros to separate math-underflow.h.	Joseph Myers	2018-05-10	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch continues cleaning up math_private.h by moving the math_check_force_underflow set of macros to a separate header math-underflow.h. This header is included by the files that need it rather than from math_private.h. Moving these macros to a separate file removes the math_private.h uses of macros from float.h, so the inclusion of float.h in math_private.h is also removed; files that were depending on that inclusion are fixed to include float.h directly. The inclusion of math-barriers.h from math_private.h will be removed in a separate patch. Tested for x86_64 and x86. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * math/math-underflow.h: New file. * sysdeps/generic/math_private.h: Do not include <float.h>.

*	ldbl-128: Use L(x) macro for long double constants	Paul E. Murphy	2016-09-13	1	-19/+19
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This runs the attached sed script against these files using a regex which aggressively matches long double literals when not obviously part of a comment. Likewise, 5 digit or less integral constants are replaced with integer constants, excepting the two cases of 0 used in large tables, which are also the only integral values of the form x.0*E0L encountered within these converted files. Likewise, -L(x) is transformed into L(-x). Naturally, the script has a few minor hiccups which are more clearly remedied via the attached fixup patch. Such hiccups include, context-sensitive promotion to a real type, and munging constants inside harder to detect comment blocks.
*	ldbl-128: Rename 'long double' to '_Float128'	Paul E. Murphy	2016-08-31	1	-4/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add a layer of macro indirection for long double files which need to be built using another typename. Likewise, add the L(num) macro used in a later patch to override real constants. These macros are only defined through the ldbl-128 math_ldbl.h header, thereby implicitly restricting these macros to machines which back long double with an IEEE binary128 format. Likewise, appropriate changes are made for the few files which indirectly include such ldbl-128 files. These changes produce identical binaries for s390x, aarch64, and ppc64.

*	Refactor code forcing underflow exceptions.	Joseph Myers	2015-09-23	1	-5/+1

This typically uses math_force_eval to ensure that the underflowing expression is evaluated, but sometimes uses volatile. This patch refactors such code to use three new macros math_check_force_underflow, math_check_force_underflow_nonneg and math_check_force_underflow_complex (which in turn use math_force_eval). In the limited number of cases not suited to a simple conversion to these macros, existing uses of volatile are changed to use math_force_eval instead. The converted code does not always execute exactly the same sequence of operations as the original code, but the overall effects should be the same.

*	Fix ldbl-128 expl missing underflows (bug 18586).	Joseph Myers	2015-06-24	1	-1/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Similar to various other bugs in this area, the ldbl-128 expl implementation does not raise the underflow exception for all subnormal results, if the scaling down is exact although the actual result is inexact. This patch fixes this by forcing the exception in this case (the tests that failed before and pass after the test are already in the testsuite). Tested for mips64. [BZ #18586] * sysdeps/ieee754/ldbl-128/e_expl.c (__ieee754_expl): Force underflow exception for small results.
