(ix86_expand_builtin): Treat OPTION_MASK_ISA_MMX similarly to OPTION_MASK_ISA_AVX512VL - builtins that have both OPTION_MASK_ISA_MMX and some other bit set require both mmx and the ISAs without the mmx bit. * config/i386/i386-builtin.def (__builtin_ia32_cvtps2pi, __builtin_ia32_cvttps2pi, __builtin_ia32_cvtpi2ps, __builtin_ia32_pavgb, __builtin_ia32_pavgw, __builtin_ia32_pmulhuw, __builtin_ia32_pmaxub, __builtin_ia32_pmaxsw, __builtin_ia32_pminub, __builtin_ia32_pminsw, __builtin_ia32_psadbw, __builtin_ia32_pmovmskb, __builtin_ia32_pshufw, __builtin_ia32_cvtpd2pi, __builtin_ia32_cvttpd2pi, __builtin_ia32_cvtpi2pd, __builtin_ia32_pmuludq, __builtin_ia32_pabsb, __builtin_ia32_pabsw, __builtin_ia32_pabsd, __builtin_ia32_phaddw, __builtin_ia32_phaddd, __builtin_ia32_phaddsw, __builtin_ia32_phsubw, __builtin_ia32_phsubd, __builtin_ia32_phsubsw, __builtin_ia32_pmaddubsw, __builtin_ia32_pmulhrsw, __builtin_ia32_pshufb, __builtin_ia32_psignb, __builtin_ia32_psignw, __builtin_ia32_psignd, __builtin_ia32_movntq, __builtin_ia32_paddq, __builtin_ia32_psubq, __builtin_ia32_palignr): Add OPTION_MASK_ISA_MMX. * gcc.target/i386/pr82483-1.c: New test. * gcc.target/i386/pr82483-2.c: New test.
