* simplify-rtx.c (simplify_subreg): Reduce problem of finding vector mode subregs of constants to finding integer mode subregs of constants. * cse.c (cse_insn): Use simplify_gen_subreg. * convert.c (convert_to_integer): Don't strip a NOP_EXPR From a vector mode expression of different size than the target mode. gcc/testsuite: * gcc.c-torture/compile/simd-3.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@55234 138bc75d-0d04-0410-961f-82ee72b054a4
