Description: Incorrect code generation for | and nested fn calls
Component: icc

icc generates incorrect code for the following
 
int g(int a, int b, int c, int d, int e)
{
  return 1;
}
 
void f(int p1, int a, int b)
{
  printf("b = %d, should be 20\n", b);
}
 
int main(void)
{
  f(g(0, 1, 2, 3, 4) | 6, 10, 20);
}
 
The problem is caused because the parameters for f which are passed in
workspace (the constant 20 in this case), are written into workspace
BEFORE the parameters for g are written into workspace (2, 3, and 4 in
this example).  So the parameter 2 for g is written over the constant
20.
 
This only occurs when calling a function with
 
  parameters passed in workspace 
 
when
  one of the parameters contains the bitwise or operator
 
and
   one of the operands of the bitwise or contains a call to a function with
   parameters passed in workspace.
 
There is no known workaround.
