[Bug rtl-optimization/37512] Useless instructions in member call by pointer

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-09-14 02:01 -------
Fixed on the trunk by the new register allocator (IRA):
__Z6callfnP1AMS_FvvE:
LFB0:
        pushq   %rbp
LCFI0:
        testb   $1, %sil
        movq    %rsi, %r11
        movq    %rsp, %rbp
LCFI1:
        movq    %rsi, -16(%rbp)
        movq    %rdx, -8(%rbp)
        je      L3
        movq    (%rdi,%rdx), %rax
        movq    -1(%rsi,%rax), %r11
L3:
        addq    %rdx, %rdi
        leave
        jmp     *%r11
