Still not quite icc's 12 seconds/200MB, but we are out of regression land for -O relative to 4.0.I tested 3.0 and it bombs on the testcase, 2.95 however compile it quite fluently on 200MB peak, it needs 6 minutes however. life analysis : 25.92 (16%) usr 0.01 ( 0%) sys 26.18 (15%) wall 2565 kB ( 1%) ggc inline heuristics : 15.15 ( 9%) usr 0.01 ( 0%) sys 15.27 ( 9%) wall 1486 kB ( 1%) ggc integration : 21.37 (13%) usr 0.12 ( 5%) sys 21.66 (13%) wall 33445 kB (19%) ggc tree SSA to normal: 27.73 (17%) usr 0.03 ( 1%) sys 27.93 (16%) wall 17 kB ( 0%) ggc local alloc : 7.33 ( 4%) usr 0.03 ( 1%) sys 7.41 ( 4%) wall 1855 kB ( 1%) ggc global alloc : 13.67 ( 8%) usr 0.73 (32%) sys 15.85 ( 9%) wall 14178 kB ( 8%) ggc reload CSE regs : 30.88 (19%) usr 0.04 ( 2%) sys 31.09 (18%) wall 2393 kB ( 1%) ggc TOTAL : 164.46 2.27 169.53 173593 kB It would be interesting to see how dataflow branch score here after re-merging from mainline. Hopefully integration and register allocation issues should be tracked there. The inliner is still quadratic in time because of quadratic split_block and cgraph_node. Both can be made linear quite easilly (split_block by always renumbering the smaller area of block and cgraph_node by producing hashtables for nodes with many edges), but I am not sure I want to do that for 4.2. Inline heuristics might be trickier to get in speed. I duno about reload. Oprofile might be handy ;) -O2 expose problem in PRE DannyB has fix for. Regmove and into-SSA can also be significantly sped up by patches I attached and will commit them once testing converge. -O3 turns the testcase into quite different one (gigantic basic block is turned into many basic blocks by inlining min/max functions). There few problems are still visible - FRE consume unbounded amount of memory and we fail to synthetize fmin/fmax operators where we ought to. If the FRE problem is fixed, I would say it should no longer be considered as 4.2 blocker. Honza -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28071
[Bug c++/28467] New: Internal compiler error (ICE) with segmentation fault for valid C++ test case
Hi,
I am working on a SH port with Gcc-3.4.5, and I am getting Internal Compiler
Error( Segmentation Fault).
I have inlcuded a CPP test case that helps to reproduce this bug on
Fedora Core 2 when compiled with optimization option "-O2".
I have debugged the Gcc code for this particular test case and found that
in function 'fixup_match_2()' from file 'regmove.c', Gcc is trying to access
'call_used_regs' with in-valid index (i.e. pseudo register).
Please refer to following code from 'regmove.c'.
/
if (call_used_regs[REGNO(dst)])
|| find_reg_fusage (p, CLOBBER, dst))

Here, I have noticed that, when the attached CPP test case is compiled with
optimization option "-O2", the "REGNO(dst)" returns pseudo register value
(i.e. 24647).
Therefore, on some OS platform like "Fedora Core 2", the above check results
into segmentation fault.
Please note that, 'segmentation fault' may not occur on some other OS as the
memory read requested by above check may fall within the allocated memory
space for executable 'cc1plus'.
Please refer to following links, where similar behavior was reported
for Gcc-4.0.2 also.
http://gcc.gnu.org/ml/gcc/2006-03/msg00318.html
The 'call_used_regs' is character array (for hard registers) with maximum size
of
'FIRST_PSEUDO_REGISTER' (i.e. 153 for SH target). Refer to file 'regclass.c'.
I have found a patch which adds a check for array index less than
'FIRST_PSEUDO_REGISTER',
http://gcc.gnu.org/ml/gcc/2005-09/msg00368.html
However, I found that this patch is not accepted.
Kindly let me know whether this patch is right fix for this bug.

--- Comment #3 from hbgku6602 at sneakemail dot com 2006-07-24 15:30 --- (In reply to comment #1) > All gcc versions I have take the template in namespace odd, and so does > icc in strict mode. I see nothing in 3.4.2 that should prevent this > from happening. What is relevant here is that the using declaration inside > the function introduces a name into the innermost namespace, thus preventing > name lookup from even looking outside the function. It would have been so say in case of int. But since A is a class-type, it has associated namespace odd, and according to 3.4.2/2a odd::f will be included in the set of declarations regardless of visibility of odd::f by ordinary rules. 3.4.2/1 "When an unqualified name is used as the postfix-expression in a function call (5.2.2), other namespaces not considered during the usual unqualified lookup (3.4.1) may be searched, and namespace-scope friend function declarations (11.4) not otherwise visible may be found." 3.4.2/2a "If the ordinary unqualified lookup of the name finds the declaration of a class member function, the associated namespaces and classes are not considered. Otherwise the set of declarations found by the lookup of the function name is the union of the set of declarations found using ordinary unqualified lookup and the set of declarations found in the namespaces and classes associated with the argument types." -- hbgku6602 at sneakemail dot com changed: What|Removed |Added CC||hbgku6602 at sneakemail dot ||com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21615

[Bug c/26542] bogus diagnostic with -pedantic?: format '%p'; expects type 'void*', but argument 2 has type 'A*'
--- Comment #4 from vz-gcc at zeitlins dot org 2006-07-24 17:02 --- I'd like to (probably uselessly but still) argue for reopening this bug and removing this warning. The interpretation of the standard text is open to questions: IMHO an "A *" pointer is a pointer to void, too, as any pointer in C is, implicitely, pointer to void. But most importantly I think this warning is absolutely useless and the only way to get rid of it is ugly (you need an explicit cast to "void *"). But, again, the most important argument against this warning is that it's 100% useless. Conversion of any pointer to "void *" is well defined and unambiguous (even in presence of multiple inheritance) and there is just no situation whatsoever in which this warning can indicate a real problem. Please consider suppressing it, thanks in advance! -- vz-gcc at zeitlins dot org changed: What|Removed |Added CC||vz-gcc at zeitlins dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26542

[Bug c/28470] New: does not inline constant funargs
Observing it at least on stage 1 compiler, and exactly the same way as
in 3.3.2.
If inline function, later called a functional, is passed a function
argument that is constant and inline, and said argument is called in
the functional body, and when inline expansions are on, compiler
expand inline only said functional, but not function argument calls in
said expansion. Instead, it handles these calls just like those of
non- inline function, that is, outputs uninlined function body and
call instruction of that body, with all call overhead.
If argument is a nested function, 4.0.3 behaves a bit better than
3.3.2. It does not output full trampoline code unnecessarily.
Priority? How should I know? Depends on projects using the compiler.

[Bug c/28473] New: with -O, casting result of round(x) to uint64_t produces wrong values for x > INT_MAX
When compiling with -O or greater optimization, and if x > INT_MAX, then code
like this:
uint64_t y = (uint64_t)round(x);
assigns the wrong value to y (the top 32 bits are all 1s). But this code
assigns the right value to z:
double dz = round(x);
uint64_t z = dz;
It almost seems as if gcc -O in some cases compiles using a built-in
declaration of round() that returns a 32-bit int.

[Bug java/28474] New: mangle_name.c mangles names unecessarily
There is a bug in mangle_name.c which leads to mangling any name containing two
underscores followed by a capital "U", even if those three characters are not
consecutive. For example, the following program will not link:
[begin Test.java]
public class Test {
public static final native void x_y_NewUser();
public static final native void xy__User();
public static void main(String[] args) {
x_y_NewUser();
xy__User();
}
}
[end Test.java]
[begin natTest.cpp]
#include "Test.h"
void Test::x_y_NewUser() {
return;
}
void Test::xy__User() {
return;
}
[end natTest.cpp]
I will attach a patch which fixes the first case but not the second (since I'm
not sure how the second case was intended to be handled).

--- Comment #5 from fxcoudert at gcc dot gnu dot org 2006-07-24 21:30 --- This one is still here, segfaulting or giving incorrect error message depending on the optimization level used for building the front-end. We enter write_symbol1 with p->u.rsym->sym.name = "sub_module", we go to p->right->u.rsym->sym.name which is "str" and then p->right->left->u.rsym->sym.name is "UCS-2BE//", which suddenly doesn't make sense :) I know you're on vacation, Paul, but I think what looks troubling to us would look trivial to you, friendly as you are with the module code in gfortran! -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||paulthomas2 at wanadoo dot ||fr Last reconfirmed|2006-05-21 20:37:51 |2006-07-24 21:30:23 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24866

[Bug c/28418] [4.0/4.1/4.2 regression] ICE incrementing compound literal expression
--- Comment #3 from fjahanian at apple dot com 2006-07-24 23:16 ---
gcc generates two separate trees for compound literals in c and c++. As in this
test case:
struct S {
int i,j;
};
void foo (struct S);
int main ()
{
foo((struct S){1,1});
}
In c it generates compound_literal_expr and in c++ it generates target_expr.
But gimplifier treats them differently in the following areas:
1) in routine mostly_copy_tree_v we don;t copy target_expr but we do copy
compound_literal_expr. I see the following comment there:
/ * Similar to copy_tree_r() but do not copy SAVE_EXPR or TARGET_EXPR
nodes.
These nodes model computations that should only be done once. If we
were to unshare something like SAVE_EXPR(i++), the gimplification
process would create wrong code. */
Shouldn't compound_literal_expr be treated same as target_expr here?
2) gimplify_target_expr can be called more than once on the same target_expr
node because first time around its TARGET_EXPR_INITIAL is set to NULL.
This works as a guard and prevents its temporary to be added to the
temporary list more than once (when call is made to gimple_add_tmp_var).
On the other hand, such a guard does not exist for a compound_literal_expr
and when gimple_add_tmp_var is called, it asserts. So, I added check for
!DECL_SEEN_IN_BIND_EXPR_P (decl) in gimplify_compound_literal_expr before
call to gimple_add_tmp_var is made. As in the following diff:
% svn diff c-gimplify.c
Index: c-gimplify.c
===
--- c-gimplify.c(revision 116462)
+++ c-gimplify.c(working copy)
@@ -538,7 +538,7 @@
/* This decl isn't mentioned in the enclosing block, so add it to the
list of temps. FIXME it seems a bit of a kludge to say that
anonymous artificial vars aren't pushed, but everything else is. */
- if (DECL_NAME (decl) == NULL_TREE)
+ if (DECL_NAME (decl) == NULL_TREE && !DECL_SEEN_IN_BIND_EXPR_P (decl))
gimple_add_tmp_var (decl);
This fixes the problem I am encouterring as well as the test case in this PR.
