------- Comment #19 from ubizjak at gmail dot com 2008-09-06 16:18 -------
Exact duplicate of PR 17236. Mainline gcc (4.4.0 20080906, IRA) generates:
pushl %ebx
movl 8(%esp), %eax
movl 16(%esp), %edx
movl 20(%esp), %ecx
movl 12(%esp), %ebx
imull %eax, %ecx
imull %edx, %ebx
mull %edx
addl %ebx, %ecx
popl %ebx
leal (%ecx,%edx), %edx
