As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include and #include_next . The x86_64 case has the further peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next . The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of , as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch.
