            Bug ID: 57503
           Summary: [4.7/4.8 Regression] Expand uses wrong multiply
                    routine
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED

         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org

cecky.c

== Test case ==

#include <stdlib.h>

long __attribute__((__noinline__))
rot (unsigned char v)
{
    unsigned vs = v * 255;
    return (long) vs * 254;
}

int main (void)
{
    long r = rot (129);

    if (r != 8355330)
        abort();
    exit (0);
}

This program hits abort if compiled with 4.7.2 or 4.8.0.

.expand dump

Notice that in rot(), long D.1484_5 is unused and instead the 32-bit value
D.1482_3 is used.

BTW, what does "w*" mean?



;; Function rot (rot, funcdef_no=4, decl_uid=1471, cgraph_uid=4)

rot (unsigned char v)
{
  long int D.1484;
  long int D.1483;
  int D.1482;
  int D.1481;

  # BLOCK 2 freq:10000
  # PRED: ENTRY [100.0%]  (fallthru,exec)
  D.1481_2 = (int) v_1(D);
  D.1482_3 = v_1(D) w* 255;
  D.1484_5 = (long int) D.1482_3;
  D.1483_6 = D.1482_3 w* 254;
  return D.1483_6;
  # SUCC: EXIT [100.0%] 
}

16-bit, of course.  In the s-file you can see that __usmulhisi3 is used.  This
is a widening 16-bit unsigned * 16-bit signed multiplication and not correct
here.

I thought this was fixed for 4.8 by bug 54295.

branch?

Using the code from comment #7 the problem persists

$ avr-gcc -S -Os pr57503.c -mmcu=atmega8 -dP


long
func1 (unsigned char a, unsigned char b, int c)
{
    unsigned ab = a * b;
    return (long) ab * c;
}


The code is a bit different but still wrong:


func1:
 ; (insn 10 5 25 (set (reg:HI 18 r18 [orig:44 D.1450 ] [44])
 ;         (mult:HI (zero_extend:HI (reg:QI 24 r24 [ a ]))
 ;             (zero_extend:HI (reg/v:QI 22 r22 [orig:50 b ] [50]))))
pr57503.c:4 168 {umulqihi3}
 ;      (expr_list:REG_DEAD (reg:QI 24 r24 [ a ])
 ;         (expr_list:REG_DEAD (reg/v:QI 22 r22 [orig:50 b ] [50])
 ;             (nil))))
    mul r24,r22     ;  10    umulqihi3    [length = 3]
    movw r18,r0
    clr __zero_reg__
 ; (insn 25 10 26 (set (reg:HI 26 r26)
 ;         (reg/v:HI 20 r20 [orig:51 c ] [51])) pr57503.c:5 82 {*movhi}
 ;      (expr_list:REG_DEAD (reg/v:HI 20 r20 [orig:51 c ] [51])
 ;         (nil)))
    movw r26,r20     ;  25    *movhi/1    [length = 1]
 ; (insn 26 25 21 (set (reg:SI 22 r22)
 ;         (mult:SI (sign_extend:SI (reg:HI 18 r18))
 ;             (sign_extend:SI (reg:HI 26 r26)))) pr57503.c:5 231
{*mulhisi3_call}
 ;      (expr_list:REG_DEAD (reg:HI 26 r26)
 ;         (expr_list:REG_DEAD (reg:HI 18 r18)
 ;             (nil))))
    rcall __mulhisi3     ;  26    *mulhisi3_call    [length = 1]
 ; (jump_insn 31 21 30 (return) pr57503.c:6 451 {return}
 ;      (nil)
 ;  -> return)
    ret     ;  31    return    [length = 1]


Insn 26 sign-extends both inputs but R18 (unsigned ab) should be zero-extended.

Tested with SVN 203240

gcc version 4.9.0 20131007 (experimental) (GCC)

Same applies to the 4.8 branch, again it is insn 26 that is wrong:

func1:
 ; (insn 10 5 25 (set (reg:HI 18 r18 [orig:44 D.1447 ] [44])

 ;      (expr_list:REG_DEAD (reg:QI 24 r24 [ a ])
 ;         (expr_list:REG_DEAD (reg/v:QI 22 r22 [orig:50 b ] [50])
 ;             (nil))))
    mul r24,r22     ;  10    umulqihi3    [length = 3]
    movw r18,r0
    clr __zero_reg__
 ; (insn 25 10 26 (set (reg:HI 26 r26)

 ;         (nil)))
    movw r26,r20     ;  25    *movhi/1    [length = 1]
 ; (insn 26 25 21 (set (reg:SI 22 r22)
 ;         (mult:SI (sign_extend:SI (reg:HI 18 r18))
 ;             (sign_extend:SI (reg:HI 26 r26)))) pr57503.c:5 231
{*mulhisi3_call}
 ;      (expr_list:REG_DEAD (reg:HI 26 r26)
 ;         (expr_list:REG_DEAD (reg:HI 18 r18)
 ;             (nil))))
    rcall __mulhisi3     ;  26    *mulhisi3_call    [length = 1]
