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. Co-Authored-By: Eric Botcazou <ebotcazou@libertysurf.fr> From-SVN: r90348
