Comments
Looks like there is problem with register description sinceVFP instruction accepts only 5 bit numbers while dflt_reg defines 64 registers. However D64 registers are accessible by pairs only (see Advanced SIMD and Floating-point register mapping) with numbers 0-31. Probably this function need to be fixed instruct vmul2F_reg_vfp(vecD dst, vecD src1, vecD src2) %{ predicate(n->as_Vector()->length() == 2 && !VM_Version::simd_math_is_compliant()); match(Set dst (MulVF src1 src2)); size(4*2); ins_cost(DEFAULT_COST*2); // FIXME format %{ "FMULS $dst.a,$src1.a,$src2.a\n\t" "FMULS $dst.b,$src1.b,$src2.b" %} ins_encode %{ __ mul_float($dst$$FloatRegister, $src1$$FloatRegister, $src2$$FloatRegister); __ mul_float($dst$$FloatRegister->successor(), $src1$$FloatRegister->successor(), $src2$$FloatRegister->successor()); %} ins_pipe(fmulF_reg_reg); // FIXME %}
