[Bug target/14563] new/delete much slower than malloc/free because of sjlj exceptions
--- Additional Comments From paulthomas2 at wanadoo dot fr 2004-11-13 11:02 --- Subject: Re: new/delete much slower than malloc/free because of sjlj exceptions Here's a test case for you... -Ken That's interesting Using your test case: (i) gcc 3.2 20020927 ( prerelease) both versions take 0.62micro-sec/new (ii) gcc 3.1.1 (cygming special) I get 2.1 and 0.66micro-sec/new (iii) gcc 4.0.0 20041010 (experimental) I get 0.62 and 0.59micro-sec/new This latter was a tad unexpected - I built in from a snapshot on one of the German mirror sites. Does this imply that I have picked up Dwarf2 as a default? Going back to the beginning of this rather long thread, you will note that it was building octave that first exposed this problem. I think that octave is calling new too many times anyway, for certain types of code, and had started hanging counters on an overloaded new operator. It would not be a big deal to substitute your version and to compare the performance with THROW defined or not. Give me a few days, the build takes a few hours under Cygwin and I have some concreting to do this weekend *sigh* Regards Paul Thomas -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14563

[Bug middle-end/18463] New: [4.0 Regression] Moving floating point through an integer register
The item Moving floating point through integer registers
on http://gcc.gnu.org/projects/optimize.html shows how GCC
can move a float array element via an integer register.
Consider the following test case:
void
fcpy(float *restrict a, float *restrict b,
float *restrict aa, float *restrict bb, int n)
{
int i;
for(i = 0; i n; i++) {
aa[i]=a[i];
bb[i]=b[i];
}
}
GCC 3.3 produces the following code for the inner loop for
-O2 -fomit-frame-pointer -fschedule-insns --std=c99:
.L6:
movl(%ebp,%ecx,4), %eax
movl(%edi,%ecx,4), %edx
movl%eax, (%esi,%ecx,4)
movl%edx, (%ebx,%ecx,4)
incl%ecx
cmpl36(%esp), %ecx
jl .L6
GCC 4.0 (4.0.0 20041112) produces this piece of junk:
.L4:
movl20(%esp), %eax
leal0(,%ebx,4), %edx
cmpl%ebx, %ebp
movl-4(%eax,%edx), %ecx
leal1(%ebx), %eax
movl%eax, %ebx
movl%ecx, -4(%edi,%edx)
movl24(%esp), %ecx
movl-4(%edx,%ecx), %eax
movl%eax, -4(%edx,%esi)
jg .L4
This is a bad regression from at least gcc 2.95 and gcc 3.1,
as demonstraded on the projects/optimize.html page.

--- Additional Comments From lpadovan at cs dot unibo dot it 2004-11-13
17:52 ---
I'm experiencing a problem with
g++-3.4 (GCC) 3.4.2 (Debian 3.4.2-3)
which seems related to this bug, at least because the error message is similar
and the operator ?: is involved. Here is the program that shows the problem:
class V;
template class P
struct S
{
S(P* p) : ptr(p) { }
operator P*() const { return ptr; }
P* ptr;
};
template class P
struct A
{
SV f(const SV x) { return (x ? x : (x ? x : 0)); }
};
and the error is:
a.cc: In member function `SV AP::f(const SV)':
a.cc:14: error: non-lvalue in unary `'
a.cc:14: error: could not convert `x' to `bool'
In
g++ (GCC) 3.3.5 (Debian 1:3.3.5-2)
the same program is compiled correctly.
Unfortunately I'm unable to test the program with the latest version of the g++
compiler, so please accept my apologies if this has been solved already.

--- Additional Comments From steven at gcc dot gnu dot org 2004-11-13

At least x86 and ARM have {reg + reg OP const} addressing
modes. Unfortunately we rip such expressions apart already
in the gimplifier. This is something we canot fix properly
on trees. TER could perhaps do it, but that pass should
really go away itself, and we don't know anything about
addressing modes on trees anyway. Looks like we need to
teach an RTL loop optimizer about this...

--- Additional Comments From pinskia at gcc dot gnu dot org 2004-11-13

For PPC at least IV-OPTS should note that we have post increment and decrement
the pointers before
the loop and then increment all of them inside the loop, aka:
void
fcpy(float *restrict a, float *restrict b,
float *restrict aa, float *restrict bb, unsigned n)
{
unsigned i;
aa-=1; a-=1; bb-=1; b-=1;
for(i = 0; i n; i++) {
aa+=1; a+=1; bb+=1; b+=1;
*bb=*b;
*aa=*a;
}
}
So we get:
L4:
lfsu f0,4(r4)
lfsu f13,4(r3)
stfsu f0,4(r6)
stfsu f13,4(r5)
bdnz L4
which is the most optimal for PPC

Here is the reduced testcase for the problem, it has nothing to do with loops
at all:
void
fcpy(float *restrict a, float *restrict b,
float *restrict aa, float *restrict bb, unsigned n)
{
aa[n]=a[n];
bb[n]=b[n];
}
DOM is doing CSE of n*4 which is the right thing to do.

The code compiles, if I make foo an ordinary (non-template) function.
The problem is similar to PR 9440. (This is in fact a reduced version
of comment #12, but I moved it here, because the original bug in PR9440
has been fixed already.)

This excerpt from java/class.c appears relavant:
void
emit_register_classes (tree *list_p)
{
if (registered_class == NULL)
return;
/* ??? This isn't quite the correct test. We also have to know
that the target is using gcc's crtbegin/crtend objects rather
than the ones that come with the operating system. */
if (SUPPORTS_WEAK targetm.have_named_sections)
{
#ifdef JCR_SECTION_NAME
tree t;
named_section_flags (JCR_SECTION_NAME, SECTION_WRITE);
assemble_align (POINTER_SIZE);
for (t = registered_class; t; t = TREE_CHAIN (t))
assemble_integer (XEXP (DECL_RTL (t), 0),
POINTER_SIZE / BITS_PER_UNIT, POINTER_SIZE, 1);
#else
abort ();
#endif
mingw doesn't currently use crtbegin.o/crtend.o -- nor any other mechanism to
init __JCR_LIST__.
I am currently testing a patch (in conjunction with DW2 EH frame support) for
this but will need about 2-3 days to go through a full bootstrap/reg-test cycle.
A safer option at this stage may be add another condition to disable for
cygwin/mingw

[Bug c++/18468] New: bad code in template function called from template class method
A template function (which swaps two values) is called in a loop in an inlined method of a template class. The number of loop iterations is a constant, so the compiler might be trying to unroll the loop. The final assignment of the swap function is not executed after the first iteration, causing incorrect results. The problem occurs with -O2 or -O3, but not with -O. I will attach a self-contained demo program. -- Summary: bad code in template function called from template class method Product: gcc Version: 3.3.3 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: james_avera at yahoo dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: i586-suse-linux-gnu GCC host triplet: i586-suse-linux-gnu GCC target triplet: i586-suse-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18468

You are violating the C++ aliasing rules:

--- Additional Comments From hp at gcc dot gnu dot org 2004-11-13 20:53 --- The part of this bug that was execution failure was another incarnation of the TImode-non-support bug mentioned in PR target/18347. There, it caused a SEGV, while here, it picked up the inner QImode in the TImode union open-coded from the vector modes, and produced wrong code.

[Bug c++/18470] New: [4.0 regression] array bound rejected as non-constant in template
The following valid code snippet is rejected by mainline:
templatetypename struct A
{
static const int i=1;
};
templatetypename T struct B : AT
{
using AT::i;
char s[i]; // fails
char t[AT::i]; // compiles
};

Mark, I suspect your patch for PR 18429 is responsible for the regression.
Could you please have a look?
