Bug ID: 57534
Summary: Performance regression versus 4.7.3, 4.8.1 is ~15%
slower
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: rtl-optimization

Reduced source code - timing functions
With x86 GCC 4.8.1, slower code is produced (than with 4.7.3) for a particular
benchmark I ran, about 15% slower.
Whatever is wrong must be happening here:
80486e5: d9 ee fldz
80486e7: d9 c0 fld %st(0)
80486e9: 8d b4 26 00 00 00 00 lea 0x0(%esi,%eiz,1),%esi

80486f7: dd 04 f3 fldl (%ebx,%esi,8)
80486fa: dc 44 03 08 faddl 0x8(%ebx,%eax,1)
80486fe: dc 44 03 10 faddl 0x10(%ebx,%eax,1)

8048710: dc 44 03 30 faddl 0x30(%ebx,%eax,1)
8048714: dc 44 03 38 faddl 0x38(%ebx,%eax,1)
8048718: 8d 46 08 lea 0x8(%esi),%eax
804871b: 39 c7 cmp %eax,%edi
804871d: de c1 faddp %st,%st(1)
804871f: 7f 0e jg 804872f
8048721: a1 34 91 04 08 mov 0x8049134,%eax
8048726: 85 c0 test %eax,%eax
8048728: 74 0e je 8048738
804872a: 83 c5 01 add $0x1,%ebp
804872d: 31 c0 xor %eax,%eax
804872f: 89 c6 mov %eax,%esi
8048731: eb bd jmp 80486f0
8048733: 90 nop
8048734: 8d 74 26 00 lea 0x0(%esi,%eiz,1),%esi
8048738: dd 5c 24 10 fstpl 0x10(%esp)
804873c: 83 c6 10 add $0x10,%esi
804873f: dd 5c 24 08 fstpl 0x8(%esp)
This is the commandline: gcc -O2 reduceme.c timer.o -o cachebench
This is from a benchmark (llcbench, GPL software) and uses timers which may be
a problem, if I preprocess them, they may not work. I'll attach the main code
(reduced) for now, and I'll work on getting the timing code included very soon.
I'll also test with 4.8.0 to see whether that version is also affected.
Attached is the reduced code minus the timing functions. Uncommenting the
commented line in the source code removes the bug.
Thanks.
Neil.

Confirmed, for some reason tree optimizers CSE part of the address, resulting
in the _.optimized dump that shows:
index.6_13 = (unsigned int) index_1;
_14 = index.6_13 * 8; <- here
_16 = x_15(D) + _14;
_17 = *_16;
_20 = _14 + 8;
_21 = x_15(D) + _20;
_22 = *_21;
_23 = _17 + _22;
_26 = _14 + 16;
_27 = x_15(D) + _26;
_28 = *_27;
_29 = _23 + _28;
_32 = _14 + 24;
_33 = x_15(D) + _32;
_34 = *_33;
_35 = _29 + _34;
sum_36 = _35 + sum_3;
_38 = _14 + 32;
_39 = x_15(D) + _38;
_40 = *_39;
_42 = _14 + 40;
_43 = x_15(D) + _42;
_44 = *_43;
_45 = _40 + _44;
_47 = _14 + 48;
_48 = x_15(D) + _47;
_49 = *_48;
_50 = _45 + _49;
_52 = _14 + 56;
_53 = x_15(D) + _52;
_54 = *_53;
_55 = _50 + _54;
sum2_56 = _55 + sum2_4;
index_57 = index_1 + 8;
Starting from there, the final assembly results in:
.L16:
leal 0(,%esi,8), %eax <- this is CSEd part: %eax = %esi * 8
fldl (%ebx,%esi,8)
faddl 8(%ebx,%eax)
faddl 16(%ebx,%eax)
faddl 24(%ebx,%eax)
faddp %st, %st(2)
fldl 32(%ebx,%eax)
faddl 40(%ebx,%eax)
faddl 48(%ebx,%eax)
faddl 56(%ebx,%eax)
leal 8(%esi), %eax
cmpl %eax, %edi
faddp %st, %st(1)
jg .L17
movl keepgoing, %eax
testl %eax, %eax
je .L18
addl $1, %ebp
xorl %eax, %eax
.L17:
movl %eax, %esi
jmp .L16
Confirmed as tree optimizers problem.

Started with SLSR addition, guess you can get the performance back with
-fno-tree-slsr. Anyway, I wonder why ivopts hasn't created TARGET_MEM_REFs for
these, I bet then SLSR wouldn't change those.

Created attachment 30263

Contained source file demonstrating bug
I have tested GCC 4.8.0 (32 bit of course) and the same slowdown is present.
The slowdown is greater with -mtune=pentium2 for some reason, but the slowdown
with no -mtune specified.
I have attached a single file with all the preprocessed source, including the
timing functions. Reducing it is difficult because it keeps hitting infinite
loops.
The command: gcc -O2 wholesource.c -o cachebench
With -O1, the bug is not present. Uncommenting the commented line so as to try
to remove the timing dependency stops the bug from occurring.
The numbers output by the executable are performance numbers, what used to be
MB/sec of read performance.
Thank you very much.
Neil Cahill.
