re PR target/18230 (SPARC VIS instructions are not generated by GCC)
PR target/18230
* doc/md.texi (SPARC constraints): Document 'Y' constraint.
* config/sparc/sparc-modes.def: Add vector modes of 4 and 8 bytes.
* config/sparc/sparc.c (sparc_vector_mode_supported_p): New function.
(TARGET_VECTOR_MODE_SUPPORTED_P): Set to sparc_vector_mode_supported_p.
(fp_zero_operand): Accept MODE_VECTOR_INT modes.
(input_operand): Accept CONST_VECTOR with MODE_VECTOR_INT modes.
(sparc_cannot_force_const_mem): Return false for CONST_VECTOR.
(sparc_init_modes): Set sparc_mode_class to SF_MODE or DF_MODE for
MODE_VECTOR_INT modes.
(sparc_extra_constraint_check): Add new constraint 'Y'.
* config/sparc/sparc.h: Define UNITS_PER_SIMD_WORD to 8 for TARGET_VIS.
* config/sparc/sparc.md (V32): New mode macro for 32-bit modes.
(V64): New mode macro for 64-bit modes.
(movsf): Use V32 for mode instead of SF.
(movsf_insn_vis): Use V32 for mode instead of SF. Add 'Y' constraint
alongside 'G' constraint.
(movdf): Use V64 for mode instead of DF.
(movdf_insn_v9only_vis, modf_insn_sp64_vis): Use V64 for mode instead
of DF. Add 'Y' constraint alongside 'G' constraint.
(multi-isn and misaligned mems DFmode splitters): Use V64 for mode
instead of DF.
