Move SNAN_TESTS_TYPE_CAST out of math-tests.h.
The math-tests.h header has many different macros and groups of macros, defined using #ifndef in the generic version which is included by architecture versions with #include_next after possibly defining non-default versions of some of those macros. This use of #ifndef is contrary to our normal typo-proof conventions for macro definitions. This patch moves one of the macros, SNAN_TESTS_TYPE_CAST, out to its own sysdeps header, to follow those typo-proof conventions more closely. Tested with build-many-glibcs.py. 2018-08-01 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/math-tests-snan-cast.h: New file. * sysdeps/powerpc/math-tests-snan-cast.h: Likewise. * sysdeps/generic/math-tests.h: Include <math-tests-snan-cast.h>. (SNAN_TESTS_TYPE_CAST): Do not define macro here. * sysdeps/powerpc/math-tests.h (SNAN_TESTS_TYPE_CAST): Likewise.
