MOVE
Mnemonic:
mov
movl
movt
movq
Format:
mov*
Copies the contents of one or more source registers (specified with src) to one
Description:
or more destination registers (specified with dst).
For
movl
register of several successive registers. src1 and dst registers must be even
numbered (e.g., g0, g2, ... or r4, r6, ...) for
four (e.g., g0, g4, ... or r4, r8, ...) for
The moved register values are unpredictable when: 1) the src and dst
operands overlap; 2) registers are not properly aligned.
Action:
mov:
if(is_reg(src1))
dst = src1;
else
{
dst[4:0] = src1;
dst[31:5] = 0;
}
movl:
if((reg_num(src1)%2 != 0) || (reg_num(dst)%2 != 0))
{
dst = undefined_value;
dst_+_1 = undefined_value;
generate_fault(OPERATION.INVALID_OPERAND);
}
else if(is_reg(src1))
{
dst = src1;
dst_+_1 = src1_+_1;
}
else
{
dst[4:0] = src1;
dst[31:5] = 0;
dst_+_1[31:0] = 0;
}
