2
3         PR target/83488
4         * config/i386/i386.opt (-mavx512vpopcntdq, -mmavx512bitalg): Move from
5         ix86_isa_flags2 to ix86_isa_flags.
6         * config/i386/i386-c.c (ix86_target_macros_internal): Test
7         OPTION_MASK_ISA_AVX512BITALG and OPTION_MASK_ISA_AVX512VPOPCNTDQ in
8         isa_flags rather than isa_flags2.
9         * config/i386/i386.c (ix86_target_string): Move -mavx512vpopcntdq
10         and -mavx512bitalg from isa2_opts to isa_opts.
11         (ix86_option_override_internal): Test OPTION_MASK_ISA_AVX512VPOPCNTDQ
12         in x_ix86_isa_flags_explicit rather than x_ix86_isa_flags2_explicit
13         and set it in x_ix86_isa_flags rather than x_ix86_isa_flags2.
14         Formatting fixes.
15         (def_builtin): Treat OPTION_MASK_ISA_AVX512BW or
16         OPTION_MASK_ISA_AVX512F ored with another option similarly to
17         OPTION_MASK_ISA_AVX512VL.  Even for OPTION_MASK_ISA_AVX512VL don't
18         clear it if mask is just OPTION_MASK_ISA_AVX512VL itself.
19         (ix86_expand_builtin): Don't handle OPTION_MASK_ISA_GFNI and
20         OPTION_MASK_ISA_VPCLMULQDQ specially, instead handle
21         OPTION_MASK_ISA_AVX512BW and OPTION_MASK_ISA_AVX512F that way.
22         * config/i386/i386-builtin.def: Move AVX512VPOPCNTDQ and AVX512BITALG
23         builtins from bdesc_args2 to bdesc_args section.
