ldbl-128ibm-compat: Provide nexttoward functions The functions in the nexttoward family are special, in the sense that they always have a long double argument, regardless of their suffix (i.e.: nexttowardf and nexttoward have a long double argument, besides the float and double arguments). On top of that, they are also special because nexttoward functions are not part of the _FloatN API, hence __nexttowardf128 do not exist. This patch adds 4 new function implementations for the new long double format: __nexttoward_to_ieee128 __nexttowardf_to_ieee128 __nexttowardieee128 (as an alias to __nextafterieee128) Likewise, rename "long double" "_Float128" in shared ldbl-128 files to ensure correct type is used irrespective of ABI switches. Thank you to those who helped out with this patch: Co-Authored-By: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>

/* Provide nexttowardl and nextafterl implementations for IEEE long double.
Update copyright dates with scripts/update-copyrights I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
