[Bug c/27479] New: TLS accesses use one more instruction than necessary
To access a TLS variable in the local-exec model, gcc will emit three
instructions, for instance (for a 64-bit compile):
addis 9,13,[EMAIL PROTECTED]@ha
addi 9,9,[EMAIL PROTECTED]@l
lwz 3,0(9)
when two instructions would suffice:
addis 9,13,[EMAIL PROTECTED]@ha
lwz 3,[EMAIL PROTECTED]@l(9)
This can be seen with a simple little program like this:
__thread int x;
int foo(void)
{
return x;
}

[Bug tree-optimization/3511] Inlined strlen() could be smarter
--- Comment #5 from rguenth at gcc dot gnu dot org 2006-05-08 09:42 ---
This is really a PRE problem, much like the simplified testcase
char firstchar (const char *s)
{
if (!s)
s = ;
return s[0];
}
where it could record the fact that the load from s[0] is available as
is strlen(s). Now, if it is worth it is another question.
Danny, will the new VN do anything about this, or make it easier to tackle
this problem? Now, ccp has moved the assignment into a PHI node, which may
make this more complicated (this is after PRE):
mystrlen (s)
{
size_t D.1648;
bb 2:
if (s_2 == 0B) goto L4; else goto L3;
L4:;
goto bb 4 (L1);
L3:;
# s_1 = PHI s_2(3), [0](5);
L1:;
# VUSE SMT.4_6;
D.1648_3 = strlen (s_1);
return D.1648_3;
}

[Bug c++/27483] New: Pointer to protected member
Dear all,
I would like to post a bug report for the GNU C/C++ compiler 3.3-e500.
We use the compiler to generate code for a PowerPC processor.
Used invokation line for the GNU C++ compiler:
ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
-fmerge-templates -mmultiple -mno-string -mstrict-align -O3
-fno-exceptions -fno-rtti -fno-builtin-printf
-Isome include paths
-Dsome #define's
X.CPP -oX.O
// file X.CPP
struct B
{
protected:
void f (int);
};
void g (void (B::*)(int));
struct D : B
{
void h1 () const { g (B::f); }// --- line 11 (illegal)
void h2 () const { g (D::f); }// --- line 12 (legal)
};
The compiler ignores that line 11 is illegal with respect to 11.5/1: If the
access is to form a pointer to member, the nested-name-specifier shall name
the derived class (or any class derived from that class).
Kind regards
W. Roehrl

[Bug tree-optimization/27497] New: store ccp does not handle constant aggregate refs of STRING_CSTs
Testcase:
/* { dg-do compile } */
/* { dg-options -O2 -fdump-tree-optimized } */
static const char f[3] = ?;
int foo()
{
int i = 0;
return f[i] != '?';
}
/* { dg-final { scan-tree-dump return 0; optimized } } */
/* { dg-final { cleanup-tree-dump optimized } } */
Problem is two-fold, for once, fold_const_aggregate_ref does not handle
STRING_CST, second, evaluate_stmt triggers the likelyvalue == CONSTANT
path only, and ccp_fold does not call fold_const_aggregate_ref.
RTL handles this. I have a patch.
