------- Additional Comments From steven at gcc dot gnu dot org 2004-11-28 00:34 ------- Here's the difference between what gcc 3.3.3 produces and what gcc 4.0.0 manages to make of it (first 3.3.3, second 4.0.0): 16,18c16,20 < movl -8(%rbp), %esi < movl -4(%rbp), %edi < call __subvsi3 --- > movl -4(%rbp), %eax > movslq %eax,%rdi > movl -8(%rbp), %eax > movslq %eax,%rsi > call __subvdi3
