Macroize function declarations in math_private.h This patch moves the declaration of many floating-point functions from math_private.h to math_private_calls.h and macroize the declaration to be dependent on floating-point type. For each of float, double, and long double, the new header file is included once. This reduces the amount of repetitive boilerplate that will be required when adding float128 versions of these functions. Tested for powerpc64le and s390x. * sysdeps/generic/math_private.h: Move the declaration of many functions to sysdeps/generic/math_private_calls.h. * sysdeps/generic/math_private_calls.h: New file with the declarations of the functions removed from math_private.h macroized by floating-point type.

/* Private function declarations for libm.
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
