Move math_check_force_underflow macros to separate math-underflow.h.
This patch continues cleaning up math_private.h by moving the math_check_force_underflow set of macros to a separate header math-underflow.h. This header is included by the files that need it rather than from math_private.h. Moving these macros to a separate file removes the math_private.h uses of macros from float.h, so the inclusion of float.h in math_private.h is also removed; files that were depending on that inclusion are fixed to include float.h directly. The inclusion of math-barriers.h from math_private.h will be removed in a separate patch. Tested for x86_64 and x86. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * math/math-underflow.h: New file. * sysdeps/generic/math_private.h: Do not include <float.h>.

Define and use libm_alias_double.
Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_double macro and uses it in the type-generic templates. This macro handles defining aliases for double, and for long double in the NO_LONG_DOUBLE case. It also handles defining compat symbols for long double = double for architectures that changed their long double format. By so doing, it eliminates the need for the M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single declare_mgen_alias call in each template now suffices to define all required compat symbols. When used for more double functions (not based on type-generic templates), I expect it will eliminate the need for most ldbl-opt wrappers for such functions. A few special cases are needed. __clog10l is a public symbol (for historical reasons) so needs to be given appropriate compat versions for architectures that changed their long double format, but is not defined as an alias using the normal macros since __clog10* are *not* public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and log1p, the changes adding errno setting support for those functions left compat symbols pointing directly to the non-errno-setting implementations. There is no requirement for the compat symbols not to set errno; that just made for the simplest patches at that time. Now, with these common macros, it's natural to redirect the compat symbols to the errno-setting wrappers, which I intend to do in a separate patch. Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt platforms the stripped libm.so binaries are changed (disassembly unchanged) because the details of how the clog10l compat symbol is created mean it ceases to be weak as it was before; for other platforms, stripped libm.so binaries are unchanged. 2017-09-13 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/libm-alias-double.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Likewise. * sysdeps/generic/math-type-macros-double.h: Include <libm-alias-double.h>.

Convert remaining complex function to generated files
Convert cpow, clog, clog10, cexp, csqrt, and cproj functions into generated templates. Note, ldbl-opt still retains s_clog10l.c as the aliasing rules are non-trivial. |

Prepare to convert remaining _Complex functions
This patch has no function changes, except to ensure the git history correctly tracks the changes to convert the double version of these functions into a templated version. |
