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:
  # remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline
  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

8700a7851b x86-64: Vectorize sincosf_poly and update s_sincosf-fma.c 
Add <sincosf_poly.h> and include it in s_sincosf.h to allow vectorized
sincosf_poly.  Add x86 sincosf_poly.h to vectorize sincosf_poly.  On
Broadwell, bench-sincosf shows:

       Before         After      Improvement
max    160.273        114.198        40%
min    6.25           5.625          11%
mean   13.0325        10.6462        22%

Vectorized sincosf_poly shows

       Before         After      Improvement
max    138.653        114.198        21%
min    5.004          5.625          -11%
mean   11.5934        10.6462        9%

Tested on x86-64 and i686 as well as with build-many-glibcs.py.

	* sysdeps/ieee754/flt-32/s_sincosf.h: Include <sincosf_poly.h>.
	(sincos_t, sincosf_poly, sinf_poly): Moved to ...
	* sysdeps/ieee754/flt-32/sincosf_poly.h: Here.  New file.
	* sysdeps/x86/fpu/s_sincosf_data.c: New file.
	* sysdeps/x86/fpu/sincosf_poly.h: Likewise.
	* sysdeps/x86_64/fpu/multiarch/s_sincosf-fma.c: Just include
	<sysdeps/ieee754/flt-32/s_sincosf.c>.
