[Bug tree-optimization/19637] Missed constant propagation with placement new
--- Comment #7 from rguenth at gcc dot gnu dot org 2005-10-09 09:47 ---
The non-null check is now removed for the foo_char() case by VRP (note that
the non-null check for the two viod-cases are _not_ removed by VRP but by DOM1.
The propagation of the initialization in foo_void_offset is layed ground
for by FRE, which changes
iftmp.3_6 = (struct Foo *) __p_5;
if (iftmp.3_6 != 0B) goto L0; else goto L1;
L0:;
this_11 = (struct Foo * const) iftmp.3_6;
this_11-i[0] = 1;
iftmp.3_12 = iftmp.3_6;
goto bb 3 (L2);
L1:;
iftmp.3_10 = iftmp.3_6;
L2:;
D.2114_7 = (struct Foo *) i[0];
D.2113_8 = D.2114_7-i[0];
return D.2113_8;
to
iftmp.3_6 = (struct Foo *) __p_5;
if (iftmp.3_6 != 0B) goto L0; else goto L1;
L0:;
this_11 = iftmp.3_6;
this_11-i[0] = 1;
iftmp.3_12 = iftmp.3_6;
goto bb 3 (L2);
L1:;
iftmp.3_10 = iftmp.3_6;
L2:;
D.2114_7 = iftmp.3_6;
D.2113_8 = D.2114_7-i[0];
which can then be optimized further. This doesn't happen for the exact
same example with void * exchanged with char * -- is FRE paying attention
to some strict-aliasing rules here? Note there is no difference in alias
information after CCP1.
For the record, the char* example mentioned would look like
int foo_char(void)
{
int i[2];
new (reinterpret_castchar *(i[0])) Foo();
return reinterpret_castFoo *(i[0])-i[0];
}

[Bug tree-optimization/19637] Missed VRP and FRE opportunities in the presence of casts
--- Comment #8 from rguenth at gcc dot gnu dot org 2005-10-09 09:56 ---
Another one is the following (without any possible aliasing problems):
int foo_charchar(void)
{
char i[2*sizeof(int)];
new (i) Foo();
return reinterpret_castFoo*(i[0])-i[0];
}
where we miss the FRE opportunity for the cast:
bb 0:
iftmp.0 = (struct Foo *) i[0];
iftmp.0-i[0] = 1;
D.2097 = (struct Foo *) i[0];
return D.2097-i[0];

[Bug target/24284] New: [4.0 4.1 regression] ICE (Segmentation fault)
[forwarded from http://bugs.debian.org/329840]
works with 3.3.6, 3.4 CVS, fails with 4.0.2, CVS HEAD 20050904
When building zinc-compiler on sparc, I'm get:
run.nw: In function 'do_run':
run.nw:212: internal compiler error: Segmentation fault
It seems the following code is what is causing it:
void do_run(void *ip)
{
char dummy[8192];
__asm__( : : g(dummy));
goto *ip;
}
A file with only that in will generate the ICE too.
It happens when using -O* and -g. -O0 or no -g makes it build.
Also, making the dummy buffer smaller than 8089 fixes it. 8089
still crashes, 8088 works without problems.
Compiling the same with gcc-3.3 or 3.4 works without problems.

Oh, the reason why smaller stacks fail is because the regnote is only created
for stack size greater than 8192.

Take the following source:
int g1(int);
int h(int *a, int *b)__attribute__((pure));
void link_error();
int g(void)
{
int t = 0, t1 = 2;
int t2 = h(t, t1);
if (t != 0)
link_error ();
if (t1 != 2)
link_error ();
g1(t2);
if (t != 0)
link_error ();
if (t1 != 2)
link_error ();
return t2 == 2;
}
We should not have link_error referenced at all.
Even on the improved aliasing branch we get:
Variable: t, UID 1278, int, is addressable, call clobbered, default def: t_1
Variable: t1, UID 1279, int, is addressable, call clobbered, default def: t1_3
That is incorrect, as t and t1 are not call clobbered as pure functions cannot
cause something to escape.

When an exception is thrown the program terminates instead of catching the exception. This only happens with -O1 or higher and -fomit-frame-pointer.

[Bug libgcj/24289] New: libjava fails to build if GNU make 3.81 betas are used (caused by feature addition, not bug, in 3.81beta -- will still happen with 3.81 final)
The problem is this new feature in make: * WARNING: Backward-incompatibility! GNU make now implements a generic second expansion feature on the prerequisites of both explicit and implicit (pattern) rules. After all rules have been parsed the prerequisites are expanded again, this time with all the automatic variables in scope. This means that in addition to using standard SysV $$@ in prerequisites lists, you can also use complex functions such as $$(notdir $$@) etc. This behavior applies to implicit rules, as well, where the second expansion occurs after the rule is matched. However, this means that you need to double-quote any $ in your filenames; instead of foo: boo$$bar you now must write foo: foobar. The presence of this feature can be detected using ifneq (,$(filter second-expansion,$(.FEATURES))) (not sure how compatible that is with non-GNU makes though) -- Summary: libjava fails to build if GNU make 3.81 betas are used (caused by feature addition, not bug, in 3.81beta -- will still happen with 3.81 final) Product: gcc Version: 4.0.2 Status: UNCONFIRMED Severity: normal Priority: P2 Component: libgcj AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bero at arklinux dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24289

This does not directly help doloop opts that work on rtl, though. There are two possible solutions: 1) Rewrite the loop on tree level to a form that is easier to analyse, e.g., for (i = 0; i != n + 1; i++) 2) Somehow pass the information that the loop is not infinite (or even that its control iv does not wrap) to rtl. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18527

prints:

The foo operand is being formatted as a pointer rather than a C string.
Strangely, the second bar operand is formatted correctly.

qemu can be found at qemu.org; I had unpacked qemu, cd'd into the directory,
and unpacked kqemu into it, then ran ./configure and make, each with no
options, as the kqemu documentation says.

Reduced testcase:

register unsigned long T0 asm(ebx);
register unsigned long T1 asm(esi);
register unsigned long T2 asm(edi);
extern int __op_param1, __op_param2, __op_param3;

d = (unsigned long long *)((char *)env + ((long)(__op_param1)));
s = (unsigned long long *)((char *)env + ((long)(__op_param2)));
*d = *s;
}

Hmm, you are starving the RA, so in a way this is not a bug. There is a dup of
this bug too.
