(In reply to comment #2)
This is an ARM (both arm32 and arm64) specific issue due to the shifts being
free. If you look at the mips assembly, it looks good for a dual issue
processor as it is scheduled as an add followed by a shift.
I think the issue is reassocdoes not know that shifts are free on arm.
This does not look like only an ARM issue. To properly demonstrate it on MIPS
and even without dual-issue, all the additions can be just changed with
multiplications (because it is a long latency instruction). In this case we
get:
unsigned int f1(unsigned int x)
{
unsigned int a, b;
a = x 1;
b = x 2;
a *= x 3;
b *= x 4;
a *= x 5;
b *= x 6;
a *= x 7;
b *= x 8;
a *= x 9;
b *= x 10;
a *= x 11;
b *= x 12;
a *= x 13;
b *= x 14;
a *= x 15;
b *= x 16;
a *= x 17;
b *= x 18;
a *= x 19;
b *= x 20;
a *= x 21;
b *= x 22;
a *= x 23;
b *= x 24;
return a * b;
}
unsigned int f2(unsigned int x)
{
unsigned int a, b;
a = x 1;
b = x 2;
a *= x 3;
b *= x 4;
a *= x 5;
b *= x 6;
a *= x 7;
b *= x 8;
a *= x 9;
b *= x 10;
a *= x 11;
b *= x 12;
a *= x 13;
b *= x 14;
a *= x 15;
b *= x 16;
a *= x 17;
b *= x 18;
a *= x 19;
b *= x 20;
a *= x 21;
b *= x 22;
a *= x 23;
b *= x 24;
asm ( : +r (a));
return a * b;
}
And the benchmark run on MIPS 74K:
$ gcc -O2 -march=mips32r2 -mtune=74kc -o badschedmul badschedmul.c
$ time ./badchedmul 1
real0m34.934s
user0m34.689s
sys0m0.073s
$ time ./badchedmul 2
real0m19.261s
user0m19.122s
sys0m0.050s
The symptoms are still the same. GCC just merges two independent calculations
into a single dependency chain. While I would have expected it to be the other
way around (breaking dependency chains to run faster on the target CPU).

[Bug tree-optimization/55629] New: Missed value numbering to a constant
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55629
Bug #: 55629
Summary: Missed value numbering to a constant
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ste...@gcc.gnu.org
Consider a classic example of non-distributivity of constant propagation:
int foo (int);
int foo (int c) {
int a, b;
if (c) { a = 3; b = 2; }
else { a = 2; b = 3; }
return a + b;
}
Value numbering should be able to determine that a+b=5. GCC successfully
optimizes the test case to just return 5 with -ftree-pre, but with only
-ftree-fre (-O1) the equivalence is not noticed.

[Bug target/55634] New: ARM: gcc vector extensions: storing vector to unaligned memory location does not use VST1.8 NEON instruction
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55634
Bug #: 55634
Summary: ARM: gcc vector extensions: storing vector to
unaligned memory location does not use VST1.8 NEON
instruction
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: siarhei.siamas...@gmail.com
The following test program tries to use GCC vector extensions to add two
vectors together and store the result to unaligned memory location in a
portable way with memcpy:
/***/
#include string.h
typedef unsigned int T __attribute__ ((vector_size (16)));
void foo (void *result, T *a, T *b)
{
T tmp = *a + *b;
memcpy (result, tmp, sizeof(tmp));
}
/***/
Compiling with gcc 4.7.2:
$ arm-none-linux-gnueabi-gcc -O2 -mcpu=cortex-a8 -mfpu=neon -c test.c
$ objdump -d test.o
foo:
0:e52d4004 push{r4}; (str r4, [sp, #-4]!)
4:ecd12b04 vldmiar1, {d18-d19}
8:e24dd014 subsp, sp, #20
c:ecd20b04 vldmiar2, {d16-d17}
10:e28dc010 addip, sp, #16
14:f26208e0 vadd.i32q8, q9, q8
18:ed6c0b04 vstmdbip!, {d16-d17}
1c:e1a0c00d movip, sp
20:e1a04000 movr4, r0
24:e8bc000f ldmip!, {r0, r1, r2, r3}
28:e584 strr0, [r4]
2c:e5841004 strr1, [r4, #4]
30:e5842008 strr2, [r4, #8]
34:e584300c strr3, [r4, #12]
38:e28dd014 addsp, sp, #20
3c:e8bd0010 pop{r4}
40:e12fff1e bxlr
The same test program results in the following code if compiled for x86-64:
foo:
0:66 0f 6f 06 movdqa (%rsi),%xmm0
4:66 0f fe 02 paddd (%rdx),%xmm0
8:f3 0f 7f 07 movdqu %xmm0,(%rdi)
c:c3 retq
So x86-64 target is able to use MOVDQU instruction. Hence ARM target should be
able to use VST1.8 as well.

[Bug c++/55635] New: Deallocation function (operator delete) not called when destructor throws exception
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55635
Bug #: 55635
Summary: Deallocation function (operator delete) not called
when destructor throws exception
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: joedoefawnb...@googlemail.com
According to C++11, 5.3.5/7, the deallocation function of a dynamically
allocated object must be called upon a `delete` expression regardless of
whether the destructor exits with an exception or not.
However, when I run the following code through valgrind, it says that I have
one still-reachable block:
struct Foo { ~Foo() { throw 0; } };
int main()
{
auto p = new Foo;
try { delete p; }
catch (...) { }
}
Am I reading the standard right that the memory should be deallocated
regardless?

For MIPS the difference is 16 instructions vs. 11 (I'm not posting the code because it is rather similar). Is this really an ARM target bug?
[Bug fortran/55636] New: [4.8 Regression] Fortran name mangling collides with user namespace

The mangling is wrong for a number of reasons: 1) It conflicts with naming used in some systems (AIX) 2) It does not obey NO_DOT_IN_LABEL 3) It does not use identifiers reserved to the system A proposal to use _F prefix instead of . was proposed and discussed, but there has been no progress.

Why can't cse_reg_info_table() be modified to intercept this?
Correction: get_cse_reg_info()
Like so, quick-and-dirty hack. HJ, can you try and see if this
keeps valgrind happy?
