This file comes from 'gcc -E isam/_packrec.c', from the MySQL 4.1.1
distribution.  This is a client's machine, so unfortunately I can't offer you a
login.  There's an easy work-around (use -O2 or -O3 instead of -O), so this
isn't critical for me.

Thanks!

[Bug target/14484] [3.3 regression] -mabi=64 and -O -> as error

Confirmed.

Here's a short testcase that causes assembler errors also for -O2 and -O3.
The 3.3 branch is affected, but not the 3.4 branch. I can't test mainline
right now.

===================================================================
int x[]= { 0 };

void foo(short **p, int *a, int *b, int i, unsigned u)
{
    while (i+1)
        if (i)
            **p= x[0];
        else
            **p= (u ? ((*a >> *b-i) & x[u]) : bar()) + 32768 + i;
}
===================================================================

I am going to assume you did not mean to close this bug, only to move the target milestone.

I don't think this bug will be fixed for 3.3.x.
The testcas is known to work 3.4.x (higher I suppose).
So closing as won't fix.
