Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '

s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

Many libm functions define the function as __<func> and then define
<func> as a weak alias. This is not at all limited to cases where
there is an internal call that has namespace reasons to need to call
__<func> instead of <func>.
The common macros for creating libm function aliases work on the basis
of public function names all being aliases; that is, they define
aliases for functions using the above pattern. Thus, where a function
just defines the public name <func> directly, changing that to be a
weak alias enables a subsequent conversion to the common macros to
retain the exact existing symbols (and so be testable by comparison of
stripped binaries).
This patch converts many existing functions to use the weak alias
pattern, as preparation for subsequent conversions to common macros.
I do expect that _FloatN/_FloatNx function aliases will end up needing
new variants of the common macros that do *not* create the original
float / double / long double name of a function - for cases where that
name is created specially to give it a particular symbol version, for
example - but for functions that can use the most common macros to
create all the public names as aliases, it makes sense for them to do
so.
Regarding the Bessel function wrappers in this patch: only float and
double wrappers are changed because the long double wrappers already
used the weak alias pattern.
Tested for x86_64, and with build-many-glibcs.py.

TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the getpayload functions for glibc; these
extract the NaN payload (from an argument passed as a pointer, for
which corresponding libm-test support is added) and return it in the
same floating-point type. The return value of these functions is
unspecified for non-NaN arguments; the patch does the simplest thing
to implement, which is that the functions do not check whether the
argument is a NaN and just treat the relevant bits of the
representation as a payload regardless. A conversion from integer to
floating-point is used to produce the required return value, except in
the ldbl-128 case; as 128-bit integers are not supported for all
configurations using ldbl-128, the code constructs the required
floating-point representation of the return value directly instead.
