[Bug web/25198] New: svn.html
Hi, currently the gcc.gnu.org/svn.html could be made clearer on how to check out a release. It mentions: SVN tags, branches and checkouts You can check out the latest version of the GCC x.y release branch with the following command: svn co svn://gcc.gnu.org/svn/gcc/branches/gcc-x_y-branch gcc By changing the gcc-x_y-branch part of the URL, you can check out particular releases or branches. this leads to people using svn co svn://gcc.gnu.org/svn/gcc/branches/gcc_X_Y_Z_release gcc instead of the correct svn co svn://gcc.gnu.org/svn/gcc/tags/gcc_X_Y_Z_release gcc I would write something like: You can check out the latest version of a GCC x.y branch with the following command: svn co svn://gcc.gnu.org/svn/gcc/branches/gcc-x_y-branch gcc while a particular release can be obtained using svn co svn://gcc.gnu.org/svn/gcc/tags/gcc_x_y_z_release gcc By changing the gcc-x_y-branch or gcc_x_y_z_release part of the URL, you can check out particular releases or branches. -- Summary: svn.html Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: web AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jv244 at cam dot ac dot uk http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25198

[Bug middle-end/25186] (short)(((int)short_var) 1) should be folded so that the shift is done in the short type
--- Comment #2 from rguenth at gcc dot gnu dot org 2005-12-01 10:53 ---
Confirmed. The first testcase is really just
short *a;
void f(void)
{
*a = *a 1;
}
interestingly, the C frontend does not do integer promotion of
unsigned short *a;
void f(voif)
{
*a = *a 1;
}
where *a should be promoted to int as of 6.3.1.8 and 6.5.7/3, which
says Integer promotions are performed on each of the operands. Now
the question is how to read this, but either the C frontend does
unnecessary promution for the signed case or it misses it for the unsigned
case.

--- Comment #7 from michael dot haubenwallner at salomon dot at 2005-12-01 11:22 --- Just for completion: The problem is not GNU ar, but GNU nm. libstdc++ does not work when built with GNU nm, but works when built with AIX nm (always without GNU as/ld, but with GNU ar/objdump/ranlib/strip). I've compared build-outputs of gcc-3.4.4 with and without GNU nm, and found this: when generating symbol list for `libstdc++.la', GNU nm says: BFD: .libs/allocator-inst.o: warning: illegal symbol index 0 in line numbers BFD: .libs/allocator-inst.o: warning: illegal symbol index 0 in line numbers This happens for powerpc-ibm-aix5.2.0.0/libstdc++-v3 powerpc-ibm-aix5.2.0.0/pthread/libstdc++-v3 but not for powerpc-ibm-aix5.2.0.0/ppc64/libstdc++-v3 powerpc-ibm-aix5.2.0.0/pthread/ppc64/libstdc++-v3 It's the same for both binutils-2.16 and 2.16.1.

convert_to_integer contains
case LSHIFT_EXPR:
/* We can pass truncation down through left shifting
when the shift count is a nonnegative constant and
the target type is unsigned. */
if (TREE_CODE (TREE_OPERAND (expr, 1)) == INTEGER_CST
tree_int_cst_sgn (TREE_OPERAND (expr, 1)) = 0
TYPE_UNSIGNED (type)
TREE_CODE (TYPE_SIZE (type)) == INTEGER_CST)
which for our case then (should) falls through to
...
/* Don't do unsigned arithmetic where signed was wanted,
or vice versa.
Exception: if both of the original operands were
unsigned then we can safely do the work as unsigned.
Exception: shift operations take their type solely
from the first argument.
Exception: the LSHIFT_EXPR case above requires that
we perform this operation unsigned lest we produce
signed-overflow undefinedness.
And we may need to do it as unsigned
if we truncate to the original size. */
if (TYPE_UNSIGNED (TREE_TYPE (expr))
|| (TYPE_UNSIGNED (TREE_TYPE (arg0))
(TYPE_UNSIGNED (TREE_TYPE (arg1))
|| ex_form == LSHIFT_EXPR
|| ex_form == RSHIFT_EXPR

|| ex_form == RROTATE_EXPR))
|| ex_form == LSHIFT_EXPR)
typex = lang_hooks.types.unsigned_type (typex);
else
typex = lang_hooks.types.signed_type (typex);
now, this path seems to handle LSHIFT_EXPR of signed types, so the exeption
above does not need to apply. Further, I don't understand the reasoning
why we need to do the shift unsigned - we invoke undefined behavior for
signed overflow, but the original code, (short) int n invoked undefined
behavior in truncating the int to short in case the value doesn't fit. Which
of course still happens for the unsigned case.
So, what would break with

[Bug c++/25199] crashing code output from -mtune=pentium4 but not -mtune=pentiumpro
--- Comment #5 from jakub at gcc dot gnu dot org 2005-12-01 14:38 --- Finding a bug in 1M of assembly is really hard without knowing where exactly to look at. Nevertheless, I suspect: movl237(%edi), %esi in _ZN14X11SalGraphics10SetXORModeEh (whereas -mpentiumpro .s has movb237(%esi), %al ). I haven't verified in detail, but it looks possible the 32bit bitfield (out of which only 14 bits are occupied) might be the last thing in the class, so if the bitfield happened to end up at END_OF_PAGE-240 bytes and nothing was mapped in the next page, a crash could happen. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25199

[Bug bootstrap/25207] New: bootstrap fails on libjava if alsa headers present but no -lasound.
This is on FC4 with alsa-lib{.i386,x86-64} installed but only
alsa-lib-devel.x86_64 (no alsa-lib-devel.i386). Hence the header
files are there, but not the libraries when building the -m32 multilib.
It looks as if configury looks for and finds header files but it's overlooked
to also look for asound libraries:
...
checking for unistd.h... (cached) yes
checking alsa/asoundlib.h usability... yes
checking alsa/asoundlib.h presence... yes

HUH? Can you give the full source/ reduced source and give a little more
detailed explication on what is going wrong.
in the file you can see a snapshort with two arrows to read and store
addresses.
It is very simple source.

static BYTE * CommTxBufHead = CommTxBuf;
static BYTE * CommTxBufTail = CommTxBuf;
static WORD CommTxNum = 0;
static void comm_txisr (void) __attribute__ ((interrupt (IRQ)));
static void comm_txisr(void)
{
DWORD tmp;
BYTE n;
if(CommTxNum)
{
tmp = 0;
for (n = 0; n 3 CommTxNum; n++, CommTxNum--)
{
tmp |= (DWORD)(*CommTxBufTail) ((n + 1) * 8);
if (++CommTxBufTail = CommTxBuf[COMM_BUF_SIZE])
CommTxBufTail = CommTxBuf;
}

[Bug target/25199] crashing code output from -mtune=pentium4 but not -mtune=pentiumpro
--- Comment #10 from jakub at gcc dot gnu dot org 2005-12-01 16:39 ---
Well, clearly it is not fixed, as proven on stock gcc-4_0-branch with:
/* { dg-do compile } */
/* { dg-options -m32 -Os -fpic -mtune=pentium4 } */
struct S
{
void *p[30];
unsigned char a0 : 1;
unsigned char a1 : 1;
unsigned char a2 : 1;
unsigned char a3 : 1;
unsigned char a4 : 1;
unsigned char a5 : 1;
unsigned char a6 : 1;
unsigned char a7 : 1;
unsigned char a8 : 1;
unsigned char a9 : 1;
unsigned char a10 : 1;
unsigned char a11 : 1;
unsigned char a12 : 1;
unsigned char a13 : 1;
};
void foo (struct S *x, unsigned char y)
{
if (! x-a12 == y)
{
x-a12 = y;
x-a3 = 0;
x-a5 = 0;
x-a6 = 0;
x-a7 = 0;
x-a8 = 0;
x-a9 = 0;
x-a10 = 0;
x-a11 = 0;
}
}
and eventhough it works on 4.1 branch, there are no signs of it actually being
fixed in any way.
IMHO, if movqi_1 wants to use movl instead of movb or movzbl, it needs to
satisfy
some predicate (whether it is aligned_operand or something else doesn't matter
much) that tells it that the optimization is safe (i.e. won't fall off the
cliff). Another thing is that aligned_operand certainly should use
MEM_ALIGN (), otherwise it will succeed only in far fewer cases than it
really could. What the predicate does ATM can be used as fallback if MEM_ALIGN
(op) 32. Now, we could perhaps safely use movl even if not aligned,
because i?86 is not a strict alignment target, if we were guaranteed we aren't
at the end of the cliff, but the question is if it is worthwhile in that case.
E.g. we could look at compute_builtin_object_size (MEM_EXPR (op), 2) and if
op is say a pointer to a middle of some structure, then we could safely use
movl.
Is movl a win when the address isn't 32-bits aligned?

Hmm, the preprocessed source file looks not all the way here:
it sends like
char *
__argp_short_program_name (void)
{
I don't know if this is becuase the preprocessor is seg faulting or it just did
not get uploaded fully?
Could you invoke the gcc comment which fails with -save-temps and -v and give
the output?

I have tracked this down to xterm not displaying utf8 even though my LANG environment variable was saying it was. A resolution to the immediate problem -- symbol names in warnings are replaced by odd characters -- is to export LANG=C before running make, then gcc uses plain old apostrophes instead of fancy matched ones around the symbol names and legacy terminals have no problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24703

}
return dist;
}
