--- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> ---
I am assuming the PR is about this difference:

$ grep frczss doc/extend.texi config/i386/i386.c
doc/extend.texi:v4sf __builtin_ia32_vfrczss (v4sf, v4sf)
config/i386/i386.c:  { OPTION_MASK_ISA_XOP, CODE_FOR_xop_vmfrczv4sf2,      
"__builtin_ia32_vfrczss",     IX86_BUILTIN_VFRCZSS,     UNKNOWN,     
(int)MULTI_ARG_1_SF },

where extend.texi should say;
v4sf __builtin_ia32_vfrczss (v4sf)

(or we could just not document those since users shouldn't use them)
