C++ (Cpp) vc_bvLeftShiftExpr Examples

Example #1

File: c_interface.cpp Project: columbia/woodpecker

Expr vc_bvVar32LeftShiftExpr(VC vc, Expr sh_amt, Expr child) {
  Expr ifpart;
  Expr thenpart;
  Expr elsepart = vc_trueExpr(vc);
  Expr ite = vc_trueExpr(vc);

  for(int count=32; count >= 0; count--){
    if(count != 32) {
      ifpart = vc_eqExpr(vc, sh_amt, 
			 vc_bvConstExprFromInt(vc, 32, count));
      thenpart = vc_bvExtract(vc,
			      vc_bvLeftShiftExpr(vc, count, child),
			      31, 0);

      ite = vc_iteExpr(vc,ifpart,thenpart,elsepart);
      elsepart = ite;
    } 
    else
      elsepart = vc_bvConstExprFromInt(vc,32, 0);    
  }  
  return ite;  
}

Example #2

File: c_interface.cpp Project: columbia/woodpecker

/* Same as vc_bvLeftShift only that the answer in 32 bits long */
Expr vc_bv32LeftShiftExpr(VC vc, int sh_amt, Expr child) {
  return vc_bvExtract(vc, vc_bvLeftShiftExpr(vc, sh_amt, child), 31, 0);
}

Example #3

{
  CAMLparam3(vc,amt,e);
  CAMLreturn(alloc_Expr(vc_bvLeftShiftExpr(VC_val(vc),Int_val(amt),
					   Expr_val(e))));
