re PR target/70296 (Incorrect handling of vector X; if X is function-like macro)
PR target/70296 * include/cpplib.h (cpp_fun_like_macro_p): New prototype. * macro.c (cpp_fun_like_macro_p): New function. * config/rs6000/rs6000-c.c (rs6000_macro_to_expand): If IDENT is function-like macro, peek following token(s) if it is followed by CPP_OPEN_PAREN token with optional padding in between, and if not, don't treat it like a macro. * gcc.target/powerpc/altivec-36.c: New test.
