Are you sure this is a regression?  I agree there is a problem here, but I see
the same results with 3.3 branch, 3.4 branch, tree-ssa and mainline when
compiling with -O2:

        .file   "pr14440.c"
        .text
        .p2align 2,,3
.globl f
        .type   f, @function
f:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        call    t
        movzbl  %al, %eax
        leave
        ret
        .size   f, .-f
        .section        .note.GNU-stack,"",@progbits
        .ident  "GCC: (GNU) 3.4.1 20040422 (prerelease)"
