5a82c74822 Prefer https to http for gnu.org and fsf.org URLs 
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)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
  s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
  $(find $(git ls-files) -prune -type f \
      ! -name '*.po' \
      ! -name 'ChangeLog*' \
      ! -path COPYING ! -path COPYING.LIB \
      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
      ! -path manual/texinfo.tex ! -path scripts/config.guess \
      ! -path scripts/config.sub ! -path scripts/install-sh \
      ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \
      ! -path INSTALL ! -path  locale/programs/charmap-kw.h \
      ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \
      ! '(' -name configure \
            -execdir test -f configure.ac -o -f configure.in ';' ')' \
      ! '(' -name preconfigure \
            -execdir test -f preconfigure.ac ';' ')' \
      -print)

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

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \
    sysdeps/csky/configure \
    sysdeps/hppa/configure \
    sysdeps/riscv/configure \
    sysdeps/unix/sysv/linux/csky/configure
  # Omit changes that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
  git checkout -f \
    sysdeps/powerpc/powerpc64/ppc-mcount.S \
    sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
  # Omit change that caused a pre-commit check to fail like this:

8f5b00d375 Move math_check_force_underflow macros to separate math-underflow.h. 
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.

24ab7723b8 Consistently use uintN_t not u_intN_t in libm. 
This patch changes libm code to make consistent use of C99 uintN_t
types instead of sometimes using those and sometimes using the older
nonstandard u_intN_t names.  This makes sense as a cleanup in its own
right, and also facilitates merges to GCC's libquadmath (which gets
the types from stdint.h and so may not have u_intN_t available at
all).

Tested for x86_64, and with build-many-glibcs.py.

02bbfb414f ldbl-128: Use L(x) macro for long double constants 
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.

15089e046b ldbl-128: Rename 'long double' to '_Float128' 
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.

d96164c330 Refactor code forcing underflow exceptions. 
Various floating-point functions have code to force underflow
exceptions if a tiny result was computed in a way that might not have
resulted in such exceptions even though the result is inexact.  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.

Tested for x86_64, x86, mips64 and powerpc.

ad39cce0da Fix sin, sincos missing underflows (bug 16526, bug 16538). 
Similar to various other bugs in this area, some sin and sincos
implementations do not raise the underflow exception for subnormal

exception in a similar way to previous fixes.
