*	Add libm_alias_finite for _finite symbols	Wilco Dijkstra	2020-01-03	1	-2/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	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.)

*	Fix y0 and y1 exception handling for zero input [BZ #21134]	Gabriel F. T. Gomes	2017-02-15	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The Bessel functions of the second type (Yn) should raise the "divide by zero" exception when input is zero (both positive and negative). Current code gives the right output, but fails to set the exception. This error is exposed for float, double, and long double when linking with -lieee. Without this flag, the error is not exposed, because the wrappers for these functions, which use __kernel_standard functionality, set the exception as expected. Tested for powerpc64le.

*	Avoid uninitialized warnings in Bessel functions.	Joseph Myers	2015-02-26	1	-2/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	math/Makefile currently has: # The fdlibm code generates a lot of these warnings but is otherwise clean. override CFLAGS += -Wno-uninitialized This is of course undesirable; warnings should be disabled as narrowly as possible. To remove this override, we need to fix files that generate such warnings, or put warning-disabling pragmas in them. This patch does so for Bessel function implementations, one of the cases that have the warnings if the override is removed. The warnings arise because functions set pointer variables p and q only for certain values of the function argument, then use them unconditionally. As the static functions in question only get called for arguments that satisfy the last condition in the if/else chain, the natural fix is to change the last "else if" to just "else", which this patch does. (The ldbl-128 / ldbl-128ibm implementation of these functions is substantially different and looks like it already does use "else" in the last case in the nearest corresponding code.)
