It would be nice if we could get 4.1.x numbers.

------- Comment #3 from gcc at pdoerfler dot com 2006-06-06 11:22 -------
I get the following with -O3 -march=pentium4 -fomit-frame-pointer on a pentium4
gentoo machine:
gcc-3.4.6 gcc-4.0.2 gcc-4.1.1
2.69s 4.14s 3.26s
These are all with gentoo's patches.
Also, current mainline is the same as gcc-4.1.1
I can confirm that the difference without -fomit-frame-pointer is much smaller.
In fact, 3.4.6 and 4.1.1 are almost the same without it.

------- Comment #6 from uros at kss-loka dot si 2006-08-16 12:15 -------
IMO the problem here is in IVopts. Using gcc-3.x, the innermost loop compiles
to:
.L15:
movl (%edi,%edx,4), %eax
fldl (%ebp,%edx,8)
addl $1, %edx
fmull (%esi,%eax,8)
cmpl %ecx, %edx
faddp %st, %st(1)
jl .L15
and with current SVN gcc-4.2 into:
.L12:
movl (%ecx), %eax
fldl (%ebp,%eax,8)
fmull (%edx)
faddp %st, %st(1)
addl $1, %ebx
addl $4, %ecx
addl $8, %edx
cmpl %esi, %ebx
jne .L12
Adding -fno-ivopts, this loop gets compiled into:
.L12:
movl (%edi,%edx,4), %eax
fldl (%esi,%eax,8)
fmull (%ebp,%edx,8)
faddp %st, %st(1)
addl $1, %edx
cmpl %edx, %ecx
jg .L12
Timings (-O3 -march=pentium4 -fomit-frame-pointer):
gcc-3.2: 0m2.301s
gcc-4.2: 0m2.713s
gcc-4.2 + -fno-ivopts: 0m2.473s
with:
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
gcc version 4.2.0 20060816 (experimental)
I think that remaining time difference is due to strange loop above innermost:
gcc-3.2:
fld %st(0)
.L16:
movl 36(%esp), %eax
fld %st(0)
movl 4(%eax,%ebx,4), %ecx

... due to strange _header_ above innermost loop ...
The problem is that we load zero in both arms of "if".
This is what I get in .099t.optimized (using gcc-4.2 -O2 -fno-ivopts):
<L1>:;
r.0 = (unsigned int) r;
D.1556 = r.0 * 4;
rowR = *((int *) D.1556 + row);
rowRp1 = *((int *) D.1556 + row + 4B);
if (rowR < rowRp1) goto <L41>; else goto <L42>;
<L42>:;
sum = 0.0;
goto <bb 5> (<L4>);
<L41>:;
i = rowR;
sum = 0.0;
Assignment to sum should be moved before if...
SSE is able to somehow CSE zero load during RTL:
.L8:
movl 20(%ebp), %edx
movapd %xmm2, %xmm1
movl (%edx,%ebx,4), %eax
movl 4(%edx,%ebx,4), %ecx
cmpl %ecx, %eax
jge .L11
movl %eax, %edx
.p2align 4,,7
.L12:

------- Comment #8 from uros at kss-loka dot si 2006-08-17 07:45 -------
Also interesting is, that -march=pentium4 produces following "de-optimized"
code, adding a couple more instructions and wasting %eax register:
.L8:
leal (%ebx,%ebx), %eax
movl 40(%esp), %edx
movl (%edx,%eax,2), %edx
movl %edx, (%esp)
movl 40(%esp), %edx
movl 4(%edx,%eax,2), %ecx
movapd %xmm2, %xmm1
cmpl %ecx, (%esp)
jge .L11
movl (%esp), %edx
.L12:
Some additiona timing can be shown (gcc-4.2 -O2 -fomit-frame-pointer):
-march=pentium4: 0m2.756s
-march=pentium4 -fno-ivopts: 0m2.500s
-march=pentium4 -fno-ivopts -mfpmath=sse: 0m2.461s
-msse2 -fno-ivopts -mfmpath=sse: 0m2.311s
In the last case, the generated code is equal to gcc-3.2 generated one:
.L8:
movl 36(%esp), %edx
movapd %xmm2, %xmm1
movl (%edx,%ebx,4), %eax
movl 4(%edx,%ebx,4), %ecx
cmpl %ecx, %eax
jge .L11
movl %eax, %edx
.p2align 4,,7
.L12:
movl (%edi,%edx,4), %eax
movsd (%esi,%eax,8), %xmm0
mulsd (%ebp,%edx,8), %xmm0
addl $1, %edx
cmpl %edx, %ecx
addsd %xmm0, %xmm1
jg .L12

Not really, the above patch fixed only one of three problems. The other two
remains, that is:
- ivopts problem (see comment #6)
- -march=pentium4 (see comment #8)
I'll try to see which option causes problems, described in #8.

Current 4.3 SVN produces (-O3 -march=pentium4):
.L8:
movl (%ebx), %eax #* ivtmp.33, tmp84
fldl (%edi,%eax,8) #
fmull (%ecx) #* ivtmp.35
faddp %st, %st(1) #,
addl $1, %edx #, i
addl $4, %ebx #, ivtmp.33
addl $8, %ecx #, ivtmp.35
cmpl %edx, %esi # i, rowRp1
jg .L8 #,
(+ -fno-ivopts):
.L8:
movl (%esi,%edx,4), %eax #, tmp76
fldl (%edi,%eax,8) #* x
movl 16(%ebp), %eax # val, <-----here
fmull (%eax,%edx,8) #
faddp %st, %st(1) #,
addl $1, %edx #, i
cmpl %edx, %ecx # i, rowRp1
jg .L8 #,
We regressed vs. 4.2 in this case; "val" is loaded inside the loop.

Re. comment #7, "Assignment to sum should be moved before if..."
This is called code hoisting, and it is not performed in GCC except with -Os.
See bug 24001, bug 33315, and other reports about the same issue in Bugzilla.

------- Comment #14 from ubizjak at gmail dot com 2008-02-06 11:05 -------
We still generate:
.L8:
movl (%ebx), %eax
addl $1, %edx
addl $4, %ebx
fldl (%edi,%eax,8)
fmull (%ecx)
addl $8, %ecx
cmpl %edx, %esi
faddp %st, %st(1)
jg .L8
This could IMO be optimized on RTL level, to use %edx as a count variable:
.L8:
movl (%ebx,%edx,4), %eax
fldl (%edi,%eax,8)
fmull (%ecx,%edx,8)
addl $1, %edx
cmpl %edx, %esi
faddp %st, %st(1)
jg .L8
This would be optimal code for this loop.

------- Comment #18 from bonzini at gnu dot org 2009-02-16 09:04 -------
For whatever reason, we're now faster than GCC 3.3.
-O2 -fno-ivopts is still faster than -O2, will open an enhancement request for
that.
