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

      ! '(' -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 \

d2f0ed09f8 ldbl-128ibm: Automatic replacing of _Float128 and L()
The ldbl-128ibm implementation of j0l, j1l, lgammal_r, and cbrtl, as
well as the tables used by expl were copied from ldbl-128.  However, the
original files used _Float128 for the type and L() for the literal
suffix.  This patch uses the following sed command to rewrite _Float128
as long double and L(x) as xL (for e_expl.c, e_j0l.c, e_j1l.c,
e_lgammal_r.c, and t_expl.h):

  sed -i <filename> \
    -e "/^#define _Float128 long double/d" \
    -e "/^#define L(x) x ## L/d" \
    -e "/L(/s/)/L/" \
    -e "/L(/s/L(//" \
    -e "s/_Float128/long double/g"

For sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c, this sed command incorrectly
replaces a few occurrences of L(), so the following command is used
instead:

  sed -i sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c \
    -e "/^#define _Float128 long double/d" \
    -e "/^#define L(x) x ## L/d" \
    -e "s/L(0\.3\{40\})/0.3333333333333333333333333333333333333333L/" \
    -e "s/L(3\.7568280825958912391243e-1)/3.7568280825958912391243e-1L/" \
    -e "/L(/s/)/L/" \
    -e "/L(/s/L(//" \
    -e "s/_Float128/long double/g"

Tested for powerpc64le with patched [1] and unpatched gcc.

c5c2e667bf ldbl-128ibm: Copy implementations from ldbl-128 instead of including them
Some files under sysdeps/ieee754/ldbl-128ibm/ are able to reuse the
implementation in sysdeps/ieee754/ldbl-128/ by defining _Float128 to
long double.  This relied on compiler support for _Float128 being
disabled.  On powerpc, such support was disabled by default, however, it
got enabled by default [1] in GCC 8.

This patch copies the implementations from ldbl-128 to ldbl-128ibm.  The
uses of _Float128 and L() are kept intact in this patch and are replaced
with a script in a subsequent patch.

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.
