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.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file COPYING
for copying permission.  The manuals, and some of the runtime
libraries, are under different terms; see the individual source files
for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.
