[Bug tree-optimization/23647] [4.0 Regression] Bug w\ while (1) loop and counter variable w\ optimization
When a while loop with the true condition (while (1)) contains
an if statement with a modulus evaluated on a counter variable, it
appears that gcc incorrectly optimizes out the modulus check as a
constant (even though the counter variable is updated after the if
statement). If the counter variable is updated _before_ the if
statement, it works properly. Example code is in the how-to-repeat section.

[Bug c++/45510] New: Bug with anonymous unions and bit-fields
I have isolated the problem to a very small test program.
There are 2 tests in main, testa builds an anonymous union with
bit-fields in it. testb builds a similar anonymous union but this time with a
named structure in it but otherwise identical members.
testa gives incorrect results (seems to ignore bit-fields). testb
gives correct results.
This is the output of the program.

[Bug bootstrap/45053] New: libgcc_s link command misses crtsavgpr_s and crtresgpr_s for powerpc
[I know this is a duplicate of 43810, but the information there is partly misleading, so I decided to file a new report.] If GCC is configured for powerpc with --enable-target-optspace, libgcc_s objects get compiled with -Os, and this causes libgcc_s to contain undefined symbols _savegpr_* and _restgpr_*. This is probably due to this commit: http://gcc.gnu.org/viewcvs?root=gccview=revrev=151729 (The use of those symbols might also depend on --with-float=soft, I didn't test with a different float option.) Those symbols _savegpr_* and _restgpr_* are defined in crtsavgpr_s.o and crtresgpr_s.o, respectively. But those objects are not linked into libgcc_s. The problem also occurs with gcc-4.5.1-RC-20100722 and with gcc-4.4.4, if the patch for pr41175 is applied.

[Bug c++/44301] New: g++ ICE on complicated template code
g++ 4.5.0 produces an ICE (segmentation fault) on the code in the
How-To-Repeat section. The error is (the first non-blank line of the
example is line 1):
test.ii: In instantiation of âeintâ:
test.ii:19:8: instantiated from here
test.ii:16:32: internal compiler error: Segmentation fault
The errors are very fragile, however. Any of the following changes make
the code compile:
- Remove struct d, or the definition of x inside it.
- Remove the U template parameter to struct d.
- Replace the use of f in d with cT::type.
- Remove either of the uses of a (e.g., changing the second line of
struct d to typename f::type x;
- Remove either of the indirections through b or c (e.g., change the
body of c to typedef int type; and then replace the uses of
cT::type with cT).
- Remove the declaration of x in struct e.
- Remove the instantiation of struct e at the end of the file.
Changing struct e to a function or wrapping the declaration of x in
struct d in a member function does not work around this problem. The
code that this was trimmed down from works on earlier versions of g++
(the actual code is from
libs/graph_parallel/test/distributed_connected_components_test.cpp in
Boost trunk r62270), and this exact code compiles on 4.1.2.

How-To-Repeat:
Noticed that gcc 4.3.4 doesn't optimize add with carry properly:
static u32
add32carry(u32 sum, u32 x)
{
u32 z = sum + x;
if (sum + x x)
z++;
return z;
}
Becomes:
add32carry:
add 3,3,4
subfc 0,4,3
subfe 0,0,0
subfc 0,0,3
mr 3,0
Instead of:
addc 3,3,4
addze 3,3
This slows down the the Internet checksum sigificantly
Also, doing this in a loop can be further optimized:
for(;len; --len)
sum = add32carry(sum, *++buf);
addic 3, 3, 0 /* clear carry */
.L31:
lwzu 0,4(9)
adde 3, 3, 0 /* add with carry */
bdnz .L31
addze 3, 3 /* add in final carry */

Suddenly GCC inserts useless moves and because of these moves has also
to generate explicit tst instructions. Older GCC versions generated better
code by using tst.b incrementing an address register without extra move
instructions, i.e. 4.4.0:

[Bug target/41021] New: [ARM] Suboptimal code generated to store a struct
A simple function to store a small struct ends up writing the struct to
memory twice unnecessarily (plus writing it for real the third time).
The function's args are passed in r0-r3 (with r1-r3 being the struct).
It compiles to a sequence containing the following loads and stores,
among others:
[1] stmfd sp!, {r0, r1, r2, r4, r5}
[2] stmia r0, {r1, r2, r3}
[3] ldmia r0, {r0, r1, r2}
[4] stmia r3, {r0, r1, r2}
[5] ldmfd sp!, {r1, r2, r3, r4, r5}
[2] and [3] seem the most egregious. (r0 points to stack space.)
However, [1] and [5] are odd too; I don't know why it's taking the time
to preserve r1-r3. Line [4] is the line that's actually necessary.
Adjusting the optimization level can eliminate the extra saves in [1],[5],
but all optimization levels seem to perform the extra save in [2],[3].

[Bug c/36951] New: uninitialized-variable warning misnames program objects after inlining
Compiling the attached piece of code produces this:
foo.c: In function 'bar':
foo.c:8: warning: 'bar_thing.member' is used uninitialized in this function
but line 8 is in foo(), not bar, and bar_thing isn't in scope.
It has inlined foo (confirmed in the assembler output) and it's
reporting about the inlined assignment, but it's doing so in a... less
than desirable way.
When I hit this on real source, the inlined function and the call site
were 1000 lines apart, and the reported name of the variable at the
call site (equivalent to bar_thing) was not illuminating, so I had
to get most of the way through preparing the minimal bug report before
I realized what was going on.
I've seen this on several configurations of gcc 4.1.2 (and also the
pre-4.1.3 snap NetBSD is currently using) but I don't have any newer
gccs than that on hand.
If you don't care because nobody cares about 4.1 any more and it
doesn't repeat on newer gccs, oh well.

At the same time, there is nothing wrong with the local symbols of

Experimenting with sources co'd from SVN (trunk), I found out that
the last revision that behaves correctly is -r96653. There was
one change in -r96654:
2005-03-18 Jan Hubicka [EMAIL PROTECTED]
* cgraph.c (cgraph_remove_node): Avoid loop in code deciding whether
function body should be released; do not proactively release function
bodies in non-unit-at-a-time mode.
Here I turned out to have arrived at the seat of the end of my
wits.
Output of `objdump -lSd' was exactly the same in both cases, but
there were many differences in the `.debug_info' section.
This seems not to be a hardware- or distribution-specific issue,
because I have the same situation on two Debian systems and on a
hand-crafted system, with both AMD64 and Pentium 4 hardware. (All
of them GNU/Linux.)
Thanks in advance,
Toomas.

[Bug c++/33468] New: C++: Invalid interpretation of friendness with nested classes
Gcc's friend-mechanism seems to expand to nested classes as well, although
the C++ standard explicitly tells differently.
The following example is almost straight from the C++ standard (11.4/2). The
only change is that inheritance is commented out for class X (in order to
remove the first error in the example). Gcc compiles this with no error
messages, even with -Wall -pedantic
// test.cc
class A {
class B { };
friend class X;
};
// INHERITANCE BELOW COMMENTED OUT BY ME
class X /* : A::B */ { // ill-formed: A::B cannot be accessed
// in the base-clause for X
A::B mx; // OK: A::B used to declare member of X
class Y : A::B { // OK: A::B used to declare member of X
// !!! The illegal line below compiles fine !!
A::B my; // ill-formed: A::B cannot be accessed
// to declare members of nested class of X
};

[Bug c/33024] New: gcc allows negatively-sized arrays
By using an integer variable as the size of an array to be
initialized on the stack, you can trick gcc into accepting
and trying to create a negatively-sized array. The assembly
it generates in such a case seems to indicate it really thinks
it has a negatively-sized array.

[Bug c/32536] New: wrong generated code on complex statement;
sample code:
#include stdio.h
int main()
{
char cp[2];
cp[0] = 'A';
cp[1] = 'B';
printf(%x %x\n,cp[0],cp[1]);
cp[0] ^= (cp[1]^=(cp[0]^=cp[1]));
printf(%x %x\n,cp[0],cp[1]);

}
The complex byte swapping instruction is far fetched but seems legal.
It actually swaps bytes if compiled with gcc -O3. Without optimization,
one of the bytes receives a '\0'.
This instruction seemed to work properly with versions 3.

[Bug c++/31816] New: If a function foo is defined before declaring a template class AT, overloaded version of foo defined after the class declaration will not be available within class AT.
Let us consider the following code:
-
void qHash(double) {}
template class T
struct QSet
{
void foo()
{
qHash(T());
}
};
// void qHash(double) {} // ok if placed here
void qHash(int*) {}
int main()
{
QSetdouble s;
s.foo(); // ok
QSetint* sp;
sp.foo(); // do not compile, qHash(int*) is not considered.
}
-
It does not compile, because the overloaded version of qHash() for
int* is not available in QSet, even if QSet is instantiated after the
declaration of qHash(int*). If no qHash function is defined before the
declaration of QSet, it works fine. Although I'm not absolutely
certain that this code is valid, my intuition tells me this behavior
is strongly suspect ..
It works fine with g++ 4.0.4, 3.3 and 2.95.

[Bug c++/31652] New: postfix increment semantics implemented incorrectly
g++ parses the code correctly and calls the correct overloaded
increment operators, but in the wrong postfix order. The semantics of
postfix are to take the rvalue before invoking the method. Note this
is not related to multiple reference ordering between sequence points
as the object is only referenced once. Although I have not checked
postfix decrement, it may have the same semantic problem and it is
trivial to adapt the supplied code.

[Bug c++/31289] New: gcc412 elides code in operator delete() override method
// BUG DEMO for gcc 4.1.2 (and 4.1.1) for 32-bit x86
//
// If operator delete() is over-ridden in a base class, then
// if the implementation of delete() stores into the storage used
// by the object, the store seems to be removed by the compiler
// (maybe because the compiler thinks stores to a deleted object
// are dead code? Or may be the casts of void * cause trouble
// with the C99 aliasing rules??)
//
// Only occurs with g++ -O3
// Occurs using native gcc on 32-bit x86.
// Does NOT occur with 64-bit x86.
// Does NOT occur with gcc 3.2.3
//
// The following program is a skeletal memory manager which maintains
// a separate free-list for each size object. Deleted objects are
// kept in a singly-linked list. operator delete() casts the void *
// pointer to be a pointer to an internal struct in order to store
// a next pointer in the first word of the storage block. The
// store through this cast pointer seems to be lost.
//
// TO DEMO THE PROBLEM:
//g++ -O3 thisfile.cpp ./a.out
//(prints ERROR and then segfaults if the bug is there)

It does not attempt to create a sub directory for nor configure libltdl at all. 2. libjava/libltdl/config.sub assumes that ../../config.sub can be found. The intention is to use srcdir/config.sub, but it cannot be refered to this way when objdir != srcdir.

[Bug target/29560] New: Poor optimization for character shifts on Atmel AVR
For setting individual bits of a register, the construct
unsigned char BitLocation = Whatever;
REG |= (1BitLocation);
is commonly used. avr-gcc fails to realize that the target register
is only 8 bits wide and performs an unnecessary 16-Bit shift of 1.
Even if this code snippet is replaced by the following:
unsigned char BitLocation = Whatever;
const unsigned char one = 1;
REG |= (one BitLocation);
The inefficient code will be generated, even with the -Os flag.
I suppose this is because the operator is not defined for 8-bit
wide data types.

}
--- Comment #1 from r dot leitgeb at x-pin dot com 2006-10-23 11:39 ---
Fix:
Define shift operators for 8 bit wide data types, use if possible.
I'm not a compiler expert but I know that the multiply operator
detects the data types involved, so it should be doable with the
shift operators as well.

I'm trying to compile svgalib (http://www.svgalib.org/) on my
FreeBSD/amd64 system.
Although the package uses assembler in a few places, this can be
disabled with the -DNO_ASSEMBLY flag. After the pre-processor
there is no assembler code in the trouble-some C-file, except
for the (unused) definitions of bswap*, which come from system
headers (sys/endian.h).
Both, the system compiler (gcc-3.4.6) and the optional gcc41
give the same error:
{standard input}:30: Error: Incorrect register `%rax' used with `l' suffix
The line number differs depending on the compiler and the
optimization options, but the error is the same, and talks about
the same piece of the gcc-generated assembly:

[Bug c/28814] New: ICE when compiling Stalin under 4.1 but not 4.0
Stalin is a Scheme compiler that generates C code. Stalin is itself written in C and can compile itself. I am preparing a new release of Stalin for Debian Etch. This release compiles with earlier versions of gcc, such as gcc-4.0, but not with gcc-4.1. It gives an ICE. The preprocessed source is huge. I submitted an earlier bug report that included the preprocessed source but apparently the email bounced. I am resubmitting making the preprocessed source available on the web instead. I would appreciate if someone from GCC/GNU can let me know when you have downloaded the preprocessed source so that I can remove it from my web site.

[Bug other/28700] New: does not fix broken linux/compiler-gcc+.h
System include file is broken as described in Fix section. fixincludes does not create any modification of it, let alone fixed as described. Newly built gcc includes broken file when run.

[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.

Some targets in `gcc/Makefile.in' built while `make bootstrap' specify `-B$(build_tooldir)/bin/'. All of this is done when nothing from gcc being built is installed in that directory yet. What is installed there, if any, generally has nothing to do with gcc at all. It may easily be files from older compiler version. Using them may do only harm.

[Bug target/28307] New: [4.1/4.2 Regression] pthread functions in libgcc not weak any more on Tru64 UNIX
While investigating the root cause of PR libgcj/28189, I noticed that both on the 4.1 branch and on mainline (where the libjava testsuite timeouts occur) the boehm-gc test had started failing as well (which easily goes unnoticed due to PR boehm-gc/11412): gctest fails like this: Key creation failed 18446744073709551615 Test failed FAIL: gctest It turns out that this happens when pthread_key_create returns -1. Printing errno at this point reveals that errno is 0, which is unexpected and shouldn't happen with the function from libpthread. Upon further investigation, it turned out that the pthread function definitions from gthr-posix.c aren't marked weak any more, so the dummy function definitions make it into libgcc.a and libgcc_s.so.1, which of course every usage of the real pthread functions. This was introduce by this patch and it's successors: 2005-11-09 Alexandre Oliva [EMAIL PROTECTED] PR other/4372 * gthr-dce.h, gthr-posix.h, gthr-posix95.h, gthr-solaris.h, gthr-tpf.h: Define __gthrw. For all identifiers that might be weak, introduce weakrefs or non-weak aliases with __gthrw, and prefix all uses with __ghtrw. Before that change, there were #pragma weak declarations for all functions defined in gthr-posix.c, so those definitions became weak. Afterwards, those declarations were lost and the definitions became strong.

[Bug boehm-gc/27963] New: [4.2 Regression] libjava fails to build if it isn't built by default
Trying to bootstrap mainline on IRIX 6.5 with java included failed since
boehm-gc (which is required for libjava) isn't built:

This happens due to this change:
2006-06-06 David Ayers [EMAIL PROTECTED]
PR libobjc/13946
* Makefile.def: Add dependencies for libobjc which boehm-gc.
* Makefile.in: Regenerate.
* configure.in: Add --enable-objc-gc at toplevel and have it
enable boehm-gc for Objective-C.
Remove target-boehm-gc from libgcj.
Add target-boehm-gc to target_libraries.
Add target-boehm-gc to noconfigdirs where ${libgcj}
is specified.
On platforms (like IRIX 6), where libjava just isn't built *by default*,
unconditionally adding boehm-gc to noconfigdirs inhibits building boehm-gc
completely, though it could build and is required for libjava.
This is a regression from the 4.1 branch.

[Bug other/27348] New: memcmp reads past end of strings
If you use memcmp to compare strings, it does not stop reading when it
finds the terminating null byte of the shortest string, which can
trigger an attempt to read unallocated memory. I'd recommend
replacing instances of memcmp on strings with strncmp, which won't
attempt to read past the end of the shortest string.

Fix:
work around, the following code will not generate warning with
'-Wall', but it looks strange.
// begin
#include tr1/array
int main() {
std::tr1::arrayint, 2 foo = {{0, 1}};
return foo[1];
}

[Bug c++/26337] New: aliasing causes stale data to be used
We are targetting the compilers for a system-on-chip solution we are
developing based on an ARM 926 which is without an FPU so we have
defaulted on SOFTWARE FLOATING POINT.
#define TARGET_DEFAULT (ARM_FLAG_SOFT_FLOAT | ARM_FLAG_APCS_32 | \
ARM_FLAG_APCS_FRAME | ARM_FLAG_MMU_TRAPS)
We run the executables either on a third party (ARM 926) development
boa
rd or
an our chip simulator. However the bug can be shown in the assembler
output.
We have come across a problem which is present in 3.4.1 compiler and
when we investigated (by quickly building) a 3.4.5 compiler we came
across the same bug. The samllest program which illustrates the bug is
brokenPointer.cxx;
/* - START */
#ifdef DEBUG
#include stdio.h
#endif
typedef unsigned intuint32_t;
typedef uint32_tData[2];
void dump( Data *data, uint32_t count )
{
uint32_ti;
for( i = 0; i count; i++ )
#ifdef DEBUG
printf( 0x%08X - 0x%08X\n, data[i][0], data[i][1] );
#else
data[i][0] += data[i][1] ;
#endif
}
float sx, sy;
void moo( float fx[2], float fy[2], uint32_t size[2], uint32_t params[2] )
{
sx = (fx[1] - fx[0]) / size[0];
sy = (fy[1] - fy[0]) / size[1];
Datadata[] = {
{ 0, 0xAA55AA55 },
{ 1, 0 },
{ 2, 1 },
{ 3, 2 },
{ 6, 16 },
{ 7, params[0] },
{ 8, params[1] },
{ 9, *((uint32_t *) sx) },
{ 10, *((uint32_t *) sy) },
};
dump( data, sizeof(data) / sizeof(*data) );
}
int main( int argc, char *argv[] )
{
float fx[2] = { -2, 2 };
float fy[2] = { -2, 2 };
uint32_tsize[2] = {64, 64};
uint32_tparams[2] = {16, 4};
moo( fx, fy, size, params );
}
/* - END */
The program we compile, brokenPointer.cxx, produces the output:
# arm-3d-linux-g++ -Os -DDEBUG brokenPointer.cxx
0x - 0xAA55AA55
0x0001 - 0x
0x0002 - 0x0001
0x0003 - 0x0002
0x0006 - 0x0010
0x0007 - 0x0010
0x0008 - 0x0004
0x0009 - 0x3D80
0x000A - 0x
When compiled and run on an (x86,say) host the final line is
correctly output as:
:: ::
0x000A - 0x3D80
We can illustrate the bug in the assembler code
arm-3d-linux-g++ -S -Os brokenPointer.cxx
illustrates the bug in brokenPointer.s
The source code section going wrong is:
-- extract start --
sy = (fy[1] - fy[0]) / size[1]; /* true value computed */
Datadata[] = {
::
{ 10, *((uint32_t *) sy) }, /* wrong value saved
he
re */
-- extract finish --
::

What happens is that the compiler has not stored the reult of the __divsf
3
which is in r0 until very late in the day. In the meantime it loads r8
from where it thinks the result is but at the time r8 is loaded it has not
yet stored r0 !

[Bug target/26051] New: libgcc_s.so.1 causes SEGV on Solaris 10/x86
Since at least 20060126, make check on Solaris 10/x86 fails with a SEGV if expect is invoked. I could trace this down to libgcc_s.so.1: If I point LD_LIBRARY_PATH at the newly built libgcc_s.so.1, expect crashes immediately, if I use one from e.g. GCC 3.1, it works as expected. Other programs (e.g. gctest in boehm-gc) are equally affected. This doesn't happen e.g. in gcc 4.1.0 as of 20060117, so this is a mainline regression. I have not been able to really debug this since I don't get any symbols when running under gdb. It seems that a deep recursion (inside libgcc_s?) is the problem: % LD_LIBRARY_PATH=. gdb /vol/tcl-8.4/bin/expect GNU gdb 6.3.50_2004-11-10-cvs Copyright 2004 Free Software Foundation, Inc.

[Bug bootstrap/26053] New: Misdetection of COMDAT group support with GNU as and non-GNU ld
When configuring the 4.1 branch (I haven't tried this on mainline yet since I only recently found a workaround for PR target/24334) on IRIX 6.5 with GNU as 2.16.1 and the SGI MIPSpro ld, libstdc++.so fails to link: ld32: FATAL 2 : Internal: at ../../ld/section_type.c In load_info() unknown section type collect2: ld returned 1 exit status make[5]: *** [libstdc++.la] Error 1 While the error message could be clearer ;-), this is obviously due to e.g. allocator-inst.o: SECTION HEADER TABLE [No] Type Addr Offset SizeName Link Info AdralgnEntsizeFlags [1]0x11 0 0x34 0x8 .group 43 0x25 0x40x40x (excerpt of elfdump -h output): Section Type 0x11 (obviously unknown to elfdump) is SHT_GROUP. While the version of GNU as used obviously supports COMDAT group, the native ld does not. It turns out that the test in gcc/configure.ac for COMDAT group support is wrong if using GNU as with a non-GNU ld: if test $in_tree_ld != yes test x$ld_vers != x; then comdat_group=yes if test 0$ld_date -lt 20050308; then if test -n $ld_date; then # If there was date string, but was earlier than 2005-03-08, fail comdat_group=no elif test $ld_vers_major -lt 2; then comdat_group=no elif test $ld_vers_major -eq 2 -a $ld_vers_minor -lt 16; then comdat_group=no fi fi if test $comdat_group = no; then gcc_cv_as_comdat_group=no gcc_cv_as_comdat_group_percent=no fi fi For non-in_tree_ld and non-GNU ld (i.e. $ld_vers empty), only gcc_cv_as_comdat_group* results from above this section are used, but instead for non-GNU ld, no COMDAT group support should be assumed. It may be that e.g. the Solaris 10+ ld does support this, but we either need a configure check for this or statically define this in configure.ac if it is hard/impossible to check at configure time. This triggers only with GNU as 2.16.1, since 2.15 on IRIX 6 SEGVs with gas COMDAT group tests, thus GNU as isn't known to support COMDAT group in 2.15.
