[Bug target/52338] New: shorter abs thumb2 code sequences
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52338
Bug #: 52338
Summary: shorter abs thumb2 code sequences
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: car...@google.com
Target: arm-linux-androideabi
Compile the following code with options -march=armv7-a -mthumb -Os
char placex[] = {1, 2, 3, 4};
char placey[] = {5, 6, 7, 8};
int t0k(int b, int w)
{
int h1 = placex[b] - placex[w];
int h2 = placey[b] - placey[w];
if (h1 0) h1 = -h1;
if (h2 0) h2 = -h2;
return h1 + h2;
}
GCC 4.7 generates:
t0k:
ldrr3, .L2
push{r4, lr}
ldrbr4, [r3, r0]@ zero_extendqisi2
addsr0, r3, r0
ldrbr2, [r3, r1]@ zero_extendqisi2
addsr3, r3, r1
ldrbr0, [r0, #4]@ zero_extendqisi2
ldrbr3, [r3, #4]@ zero_extendqisi2
subsr2, r4, r2
subsr3, r0, r3
eorr0, r2, r2, asr #31// abs(h1)
subr0, r0, r2, asr #31// abs(h1)
cmpr3, #0 // abs(h2)
itlt // abs(h2)
rsbltr3, r3, #0 // abs(h2)
addsr0, r0, r3
pop{r4, pc}
It's interesting that gcc generats two different code sequence for abs(h1) and
abs(h2).
After carefully studying the insn pattern *thumb2_abssi2, I got the
impression that the selection of code sequence is depends on if the result
register is same as source register. If they are same, the cmp code sequence is
used, otherwise the pure arithmetic code sequence is used.
But the cmp code sequence can also be used when the source is not the same as
target register, and may result in smaller code size, like in this case.
Another question is there any performance differences between these two
different code sequences?

You surely win the obfuscated C++ contest with this testcase as well as with
your description of your issue.
Please re-format to something readable and let someone with better english
language skills double-check your bug description.
If your issue is that class a{int i;virtual void t()=0;}; is not of sizeof
(int)
then this is because it still has a virtual table.

(do you have something against whitespace?!)
could you explain exactly what you think GCC does wrong, and what you expect to
happen?
I'm afraid I don't understand your report.
Here's the same code, once more with formatting:
typedef char**(*(*v[4])(int*p[],float (*f)(int a[])))[][6];
class e{ v i,a,b;
public:
int get();
friend int g();
} ai;
int e::get() {
long h1,h2,h3;
h1=(long)i;
h2=(long)a;
h3=(long)b;
__builtin_printf(%p\n%p %lx\n%p %lx\noriginal pointer is:
%p\n,i,a,h2-h1,b,h3-h2, i);
return 0;
}
int g(){ return ai.get(); }
class pgabstract{
v i,a,b;
public:
int get() {return vget();}
int(*p)();
virtual void t()=0;
int vget();
} *m[4];
int pgabstract::vget()
{
long h1,h2,h3;
h1=(long)i;
h2=(long)a;
h3=(long)b;
__builtin_printf(%p\n%p %lx\n%p %lx\noriginal pointer is:
%p\n,i,a,h2-h1,b,h3-h2, i);
return 0;
}
int main(){
m[3]=(pgabstract*)ai;
m[3]-get();
}
When I run this I get:
0x600b48
0x600b68 20
0x600b88 20
original pointer is: 0x600b48

What is not ok is that the first operand of the MEM_REF is not is_gimple_mem_ref_addr (). Valid would be (MEM_REF (s + 0).D.2422) for example, which fold would canonicalize the MEM_REF sub-tree to. Unfortunately we do not verify anything in gimple_debug stmts :( [sorry for the un-obfuscation during pretty-printing ;)] It seems that this is introduced by propagating into debug stmts as we go from t.ii.058t.copyrename2: # DEBUG D#4 = D.2734_8-D.2422 t.ii.058t.copyrename2: # DEBUG this = D#4 to t.ii.060t.ccp2: # DEBUG D#4 = s.c.D.2422 t.ii.060t.ccp2: # DEBUG this = D#4 and the issue there seems to be that GIMPLE_DEBUG handling in fold_stmt does not look at ADDR_EXPRs but only REFERENCE_CLASS_P stuff. See the ADDR_EXPR handling in fold_gimple_assign.

I'm not sure we care about preserving pointer types in debug stmts, nor if
the mem-ref stripping is needed (well, build_fold_addr_expr does that, too).

[Bug c++/52339] New: using delete ptr1-ptr2 where ptr2 destructor deletes a const ptr1 fails
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52339
Bug #: 52339
Summary: using delete ptr1-ptr2 where ptr2 destructor deletes
a const ptr1 fails
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: romb...@hotmail.co.uk
The following code crashes and triggers the valgrind error with gcc 4.4 and
4.6. With clang it works just fine. And it also works fine if you remove
const on line 15
***
struct B;
struct A {
B* b;
};
struct B {
A* a;
B() : a(new A{this}) {}
~B() { delete a; }
};
int main() {
B* b = new B;
// A* a = b-a;
const A* a = b-a;
delete a-b;
}
**
I have no idea if is it undefined behaviour to delete a-b if b deletes a.
Expressions should be evaluated only once, but for some reason this line:
delete a-b;
is basically acting as if was written like:
a-b-~B();
operator delete(a-b); // a is already deleted

[Bug target/52338] shorter abs thumb2 code sequences
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52338 Richard Earnshaw rearnsha at gcc dot gnu.org changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2012-02-22 Ever Confirmed|0 |1 --- Comment #1 from Richard Earnshaw rearnsha at gcc dot gnu.org 2012-02-22 11:52:48 UTC --- The sequence that doesn't need conditional execution will generally execute in just two cycles, the version using the conditional execution will take 3 (perhaps more) as on some cores conditional instructions can be quite slow (though still faster than branching if there is no pattern to that the branch predictor can lock onto). The patterns to deal with these sequences were originally written for ARM state and have been subsequently converted to also handle Thumb2. In ARM state both sequences need 8 bytes and the non-compare version is clearly preferable.

The code that is reason-aware saves the enum and builds a good message; the legacy code that is not reason-aware treats the enum as a bool and works as before except for the inverted sense of the test. Maybe half an hour of work. Plausible? Plausible in theory, sadly unrealistic in practice. But I would like to be proven wrong, so give it a try.

The note the assert fails on is NOTE_INSN_DELETED, so one has to wonder why we don't throw such notes away during the scheduling, or at least don't fail the assertion on those.

[Bug go/52341] New: crypto/rand FAILs before Solaris 11
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52341
Bug #: 52341
Summary: crypto/rand FAILs before Solaris 11
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
AssignedTo: i...@airs.com
ReportedBy: r...@gcc.gnu.org
Host: *-*-solaris2.{8,9,10}
Target: *-*-solaris2.{8,9,10}
Build: *-*-solaris2.{8,9,10}
Before Solaris 11, the libgo crypto/rand test FAILs like this:
--- FAIL: rand.TestRead (0.00 seconds)
???:1: Read(buf) = 1040, %!s(nil)
FAIL
FAIL: crypto/rand
There's a limit on /dev/urandom here, while not properly documented in
random(7D), it can be found in the OpenSolaris sources and is alluded to in
Solaris 11 random(7D):
The limitation per read for /dev/random is 1040 bytes. The
limit for /dev/urandom is (128 * 1040).
The 1040 byte limit also applies to /dev/urandom before Solaris 11.

[Bug web/52239] Upgrade GCC Bugzilla to 4.2
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52239 --- Comment #2 from Frédéric Buclin LpSolit at netscape dot net 2012-02-22 19:25:45 UTC --- Bugzilla 4.2 has been released today. But overseers told me that bzr (Bazaar) cannot be installed on the server because it has a too old version of Python. As Bugzilla 4.0.x is the last branch to have a CVS mirror of the upstream bzr repository, I will have to wait for the upgrade of the server before I can install Bugzilla 4.2 using bzr. Meanwhile, I will keep doing minor upgrades on the 4.0.x branch.
