--- Comment #4 from pinskia at gcc dot gnu dot org 2006-11-12 08:35 ---
The only thing left from __task_rq_lock is a label.
If we look at that inlined function, we see:
static inline __attribute__((always_inline)) struct rq *__task_rq_lock(struct
task_struct *p)
{
struct rq *rq;
repeat_lock_task:
rq = (&(*((void)((task_cpu(p))), &per_cpu__runqueues)));
do { do { } while (0); (void)0; (void)(&rq->lock); } while (0);
if (__builtin_expect(!!(rq != (&(*((void)((task_cpu(p))),
&per_cpu__runqueues, 0)) {
do { do { } while (0); (void)0; (void)(&rq->lock); } while (0);
goto repeat_lock_task;
}
return rq;
}
the if is never true as rq is always equal to &per_cpu__runqueues. The calls to
task_cpu were inlined and we constant proped the value of rq the first of the
way through the function which we inlined this to.

[Bug c++/29518] [4.0/4.1/4.2/4.3 Regression] rejects valid template argument, enums vs templates
--- Comment #12 from news at derived-software dot ltd dot uk 2006-11-12
11:04 ---
>From Aleksey Gurtovoy (co-author Boost.MPL):
[wrt to this bug]
Actually, no, enums in the bug's subject and reduced test case are a
red herring. For example, this still fails for me on 4.1.1:
template< int C > int assertion_failed(int);
template< class > struct N
{
static int const value = 1;
static int const t = sizeof( assertion_failed(0) );
};
int main()
{
N n;
return n.t;
}
As a matter of fact, my current workaround for this issue involves
_introducing_ an auxiliary enum for the values that are used in
function templates' non-type arguments, e.g.:
template< int C > int assertion_failed(int);
template< class > struct N
{
static int const value = 1;
enum { gcc_workaround = value };
static int const t = sizeof( assertion_failed(0) ); // it
compiles, yay!
};

No, GCC cannot in general detect whether your asm code is buggy. The assembler however can detect many asm bugs, as it did in this case. The reason it worked with -O0 is that with -O0 you get different generated code (namely, very inefficient code). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29808

# SFT.56D.1998_59 = V_MAY_DEF ;
__comp_ctor (&D.1854, &start_dateD.1966, &stop_timeD.1963)
right after running the first alias pass. This is from the inliner
replacing
__comp_ctor (&, &start_date, &stop_time);
with D.1854 here.
It looks we simply forget to mark the decl addressable during inline
substitution here:
/* Variable substitution need not be simple. In particular, the
INDIRECT_REF substitution above. Make sure that TREE_CONSTANT
and friends are up-to-date. */
else if (TREE_CODE (*tp) == ADDR_EXPR)
{
walk_tree (&TREE_OPERAND (*tp, 0), copy_body_r, id, NULL);
/* Handle the case where we substituted an INDIRECT_REF
into the operand of the ADDR_EXPR. */
if (TREE_CODE (TREE_OPERAND (*tp, 0)) == INDIRECT_REF)
*tp = TREE_OPERAND (TREE_OPERAND (*tp, 0), 0);
else
recompute_tree_invarant_for_addr_expr (*tp);
*walk_subtrees = 0;
}
or it should have been marked addressable earlier. That we don't hit
this more often and that trunk doesn't have the problem hints at that
the following is not the right fix?

--- Comment #3 from mmitchel at gcc dot gnu dot org 2006-11-12 21:33 --- This is a tricky case, since the underlying memory pointed to by the pointer is non-volatile. In other words, the compiler knows that "s" is non volatile, even though the pointer type is "volatile int *". The C99 standard (5.1.2.3) says that "accessing a volatile object" is a side-effect. The C++ standard ([basic.intro]), however, says that "accessing an object designated by a volatile lvalue" is a side-effect. In this case, I would think the object to be non-volatile, but the lvalue to be volatile.

There's nothing non standard about the names. However, there are some special issues. I don't believe that it's possible to switch out of the text for any given function and back in. This is definitely not possible under hpux. For this reason, we don't support hot and cold text. Switching out of the text section would affect the calculation of branch distances and possibly affect the placement of the stub tables used to convert short pc-relative branches to long branches. The EH tables use an indirect pc-relative encoding for global and function pointers. This avoids having any dynamic relocations in the EH data, but there has to be a fixed relationship between text and data in dynamic objects for this to work. The PA handling of function pointers is also somewhat unique and based on the original hpux implementation. Thanks for the patch update. I'll give it a try. Unfortunately, I didn't have time this weekend to work on this. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29639

[Bug c++/29607] [DR 224] [4.1/4.2/4.3 Regression] dependent name with base classes
--- Comment #11 from mmitchel at gcc dot gnu dot org 2006-11-13 03:38
---
I am going to put these DR 224 issues into WAITING. I don't think we really
know what the committee is going to do yet.
(Prior to that DR being put into the WP, I had a long discussion with John
Spicer. My feeling is that in:
template
struct S {
...S...
}
S should be dependent. DR 224 says that it should not dependent.
My feeling is that dependence should be an intrinsic property of a type,
independent of context. John's feeling is that making its dependence
conditional makes things easier for programmers (although clearly harder for
compilers).
For example, in the test case in Comment #5, one can in fact prove that
WxVector::IterBase is the global class, independent of any specializations.
That is the argument it should not be dependent. However, in:
template
struct S {
... sizeof(S) ...
}
the sizeof expression must be value-dependent, even though S is not
type-dependent, which is odd. (This case doesn't seem to be addressed by DR
224; AFAICT, DR 224 as written would make sizeof(S) non-dependent. Clearly,
that could be fixed by explicitly noting this case.) I find the fact that a
non-dependent type can have a dependent size to be weird.)

[Bug java/29812] New: env->klass value is not updated during the native calls
Hello, While debugging the issue with the Subclipse not working under the GCJ (look at the message http://svn.haxx.se/subusers/archive-2006-07/0210.shtml for example) I found the following problem. When native method is called, the env->klass value is always NULL. It looks like that JNIEnv is reused in the "_Jv_GetJNIEnvNewFrame" function and the env->klass value is not updated during the call. For more details look at the message here: http://gcc.gnu.org/ml/java-patches/2006-q3/msg00231.html P.S. Steps to reproduce behavior: 1. Install gcj-4.1.1. 2. Run Eclipse with -vm /path/to/gij 3. Install Subclipse extension (http://subclipse.tigris.org). 4. Open Windows->Preferences dialog, then open Team->SVN tab. The Eclipse shows error message. -- Summary: env->klass value is not updated during the native calls Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: java AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: wfragg at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29812

--- Comment #1 from erik dot edelmann at iki dot fi 2006-11-13 07:42 --- Isn't this going to be allowed in F2008? (Perhaps it already is in F2003 -- I'm too lazy to check.) We should print an error message if strict standard conformance is requested, but since it is going to be valid code in the future, I think we can continue to support it. -- erik dot edelmann at iki dot fi changed: What|Removed |Added CC||erik dot edelmann at iki dot ||fi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29806
