[Bug c/15062] New: Invalid operand to binary operator

[aj at gcc dot gnu dot org]

Building glibc with current GCC tree-ssa, I get an ICE:

I can confirm this on alphaev68-linux with tree-ssa 20040416. Test case:

void next (double x) {
    x = x + x;
    asm("" : : "m"(x));
}

Here is the reduced sources I came up with on i686:
double a(double x)
{
   x = x+x;
   asm ("" : "=m"(x) );
   return x;
}

>From what I can tell, it looks like 'x' is being marked as addressable when the
asm expression is gimplified and after the x=x+x expression is gimplified,
making 'x' an invalid operand in the x=x+x expression.

My knowledge of the gimplifier is limited, so I don't know exactly how to fix this.

Hmmm...  With:
GNU C version 3.5-tree-ssa 20040504 (merged 20040428) (x86_64-unknown-linux-gnu)
        compiled by GNU C version 3.5-tree-ssa 20040504 (merged 20040428)

I can't reproduce this.  Not with the small test case and also not with Andreas'
test case.

Andreas, do you still see this problem?

Is this fixed?

I can reproduce this with the following at -O3:

double __nextafter(double x, double y)
{
 int ix;
 unsigned int lx;

 if((ix-0x7ff00000)!=0)
    return x+y;

 asm ("" : "=m"(x) : "m"(x));

}

I forgot that I compiled my compiler with checking disabled, so this might still happen.

I think I have a patch which fixes the problem, it marks the operand while converting to 
generic to be makred as addressable which I am testing right now.

Actually the easy fix is to copy what the C++ front-end does and that fixes the problem.  I 
will submit a patch for that.
