I can confirm that, with these patches applied, the .sched log file looks 
better. The structure has now the correct size:

(insn 79 105 41 (parallel[ 
            (set (mem/s/j:BLK (reg/f:SI 130) [0 pty_driver.init_termios+0 S36 
A32])
                (mem/s:BLK (reg/f:SI 131) [0 tty_std_termios+0 S36 A32]))
            (clobber (reg/f:SI 130))
            (clobber (reg/f:SI 131))
            (clobber (reg:SI 132))
            (clobber (reg:SI 133))
            (clobber (reg:SI 134))
            (use (const_int 36 [0x24]))
            (use (const_int 4 [0x4]))
        ] ) 108 {movstrsi_internal} (insn_list 78 (insn_list 76 
(insn_list:REG_DEP_ANTI 20 (nil))))

and the assignment to c_lflag has now the correct output dependency:

(insn 100 89 29 (set (mem/s/j:SI (plus:SI (reg/f:SI 95)
                (const_int 40 [0x28])) [0 pty_driver.init_termios.c_lflag+0 
S4 A32])
        (const_int 0 [0x0])) 68 {*pa.md:2088} (insn_list 9 
(insn_list:REG_DEP_ANTI 20 (insn_list:REG_DEP_OUTPUT 79 (nil))))
    (nil))

but I can't formally assert that the bug is fixed because I don't speak 
PA-RISC (which appears to be a bit abstruse :-)


Could you post the ChangeLog entries corresponding to the patches?
