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.

* sysdeps/ieee754/ldbl-128ibm/e_expl.c: Remove definitions of
_Float128 and L().
* sysdeps/ieee754/ldbl-128ibm/e_j0l.c: Remove definitions of
_Float128 and L(). Replace _Float128 with long double and L(x)
with xL, throughout the file.
* sysdeps/ieee754/ldbl-128ibm/e_j1l.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm/e_lgammal_r.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm/t_expl.h: Likewise.
