--- Comment #1 from christophe at saout dot de 2006-11-07 11:23 ---
The function test (even compiled with -O0, on i386 BTW) assumes that the
condition can never occur, as the complete if condition is completely optimized
away and the function always returns 1.
#include stdlib.h
int test(int x)
{
if (((unsigned int)x 3) 0x0800)
return 0;
return 1;
}
int main(void)
{

'make check' for gcc-3.4.6 fails
Hello,
I am building gcc-3.4.6 in the framework of my tool (see signature).
It's a native build on Mandriva 2006 IA32 Linux.
The essence of my tool is that it builds and installs every target in a separate
directory, other than that it uses
./configure
make
make check
make install
sequence.
If the failures are known and do not reperesent real problems, how can I skip
the failing tests, i.e. what files to edit or to remove, etc. ?
Please find scree output of 'make check' below.
Please let me know what additional info you need to debug the problem.
Thanks,
Sergei.

Note for completeness: With PR 29601 the TYPE_QUAL_VOLATILE is used for for
VOLATILE variables (see -fdump-tree-original; however, the word volatile does
not show up in the dump for pointers and arrays, even though they are treated
as volatile correctly; cf. gfortran.dg/volatile{6,7}.f90.)

[Bug fortran/29752] New: [4.2/4.3 Regression] write(*,*,advance='NO'), READ(): Data not flushed
If one uses advance = NO, after the write a FLUSH should be called. - program test implicit none character(20) :: fname WRITE(*,ADVANCE='NO',FMT='(A)') Input name of file? READ(*,'(a)') fname print *, 'Read: ',trim(fname) end program test - If you run this program with gfortran (trunk) or with gfortran-4.2 the result is: x Input name of file? Read: x However, using gfortran-4.1 (20061024), NAG f95, ifort, g95 sunf95 the result is: Input name of file?x Read: x Expected: For advance='NO' the output should probably flushed. Or alternatively, for read(*) the output to that unit should be flushed first. I don't know what is the best way, to work (a) reliably and (b) does not have a too big performance penalty. A test using call sleep(3) instead of read() shows that ifort, NAG f95 and sunf95 flush on the read, g95 and gfortran-4.1 on the write. I think the ifort/NAGf95/sunf95 is better since one only needs to have everything flushed if one wants to read. In addition, the same problem could happen if one does a buffered write() with advance=YES. (I don't know what gfortran currently does. ifort supports, e.g., -assume nobuffered_io (default) and -assume buffered_io. It it seems to buffer for advance='yes' using no options.) -- Summary: [4.2/4.3 Regression] write(*,*,advance='NO'), READ(): Data not flushed Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29752

[Bug target/29746] gcc fails to bootstrap on sh4-*-linux-gnu
--- Comment #7 from amylaar at gcc dot gnu dot org 2006-11-07 17:05 --- Created an attachment (id=12564) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12564action=view) I have a new patch for sched-deps.c now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29746
[Bug c/29753] New: Volatile semantics ignored in some cases
The following function:
static struct { int w; } s;
void wait (void) {
int t;
loop:
t = *((volatile int *) s.w);
if (t 0) goto loop;
}
is compiled incorrectly with gcc -v -O3 v.c -o v.s -Wall -S. The generated
assembly does not respetc the semantics of volatile:
wait:
movls, %eax
pushl %ebp
movl%esp, %ebp
testl %eax, %eax
jg .L6
popl%ebp
ret
.L3:
.L6:
jmp .L6
The attached testscase shows the problem. It also includes a similar function
which does get compiled correctly, the only difference is that it introduces a
temporary variable.

The variables aren't being collapsed, but i can't figure out why (IE it can't prove they are the same). This causes it to give them separate solution bitmaps, and the solutions are very large,and involve thousands of variables, so thousands * thousands = a lot of memory. It appears that every one of them has its address taken. The code skips such variables: /* We can't eliminate things whose address is taken, or which is the target of a dereference. */ if (vi-address_taken || vi-indirect_target) continue; However, all of these variables should collapse, as they do in the earlier functions. For the record, I believe we die processing this constructor function: ;; Function _GLOBAL__I_0__ZN3gnu3xml8aelfred215XmlParser$InputC1Ev() (_GLOBAL__I _0__ZN3gnu3xml8aelfred215XmlParser$InputC1Ev) The alias1 files has the following: ...

PaulT Yes, I was just racing for the standard. apinski ok apinski I guess I have to change my patch then apinski to include a size comparision apinski The physical representation of the result is the same as SOURCE, truncated if the result is smaller or with an undefined trailing portion if the result is larger. apinski that is from IBM's docs about transfer PaulT apinski: Gee, yes.

PaulT apinski: I keep telling people that that is what it is for! PaulT apinski: Sure thing - I suppose that you can safely do a kind conversion? apinski I know how to fix this correctly now apinski use __builtin_memcpy and hope that gets optimized correctly in the future :) PaulT apinski: make type of the same length as source, so that the assignment does the rest? apinski no apinski PaulT: do memcpy (dst, src, min(size1, size0)) PaulT apinski: No... you're right that won't present a bit-wise transfer. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29410

Clearly I'm doing something different than you are. I can speculate that one of a few things might be happening. 1. We might have some kind of memory corruption or similar bug causing us to zero the SSA_NAME_DEF_STMT/TREE_CHAIN field of the affected SSA_NAME. Possible, but unlikely. 2. We have an SSA_NAME in the IL which was deleted. 3. Something else totally unexpected. #2 has happened in the past and I'd consider it the most likely culprit. What is interesting is that a checking failure was not triggered -- our SSA verifiers should be checking for case #2 and issuing an error. So let's start with checking a couple things. 1. Put a breakpoint in tree_ssa_cd_dce when compiling the offending function from recog.c.When that breakpoint triggers issue: verify_ssa (true) I can't see any way for that to fail, but better safe than sorry. 2. When the gcc_assert triggers, issue: debug_tree (op) debug_generic_stmt (op) 3. Send me the phi-only copyprop dumps. If #1 passes and #2 indicates the name in question is on the free list, then either DCE is mucking things up or we have out-of-date operands in the operand cache relative to the IL (which I can detect with the dumps).

[Bug inline-asm/29756] New: SSE intrinsics hard to use without redundant temporaries appearing
I've been adapting some old codes' simple 4-float vector class to use SSE by use of the intrinsic functions. It seems to be quite hard to avoid the generated assembly code being rather diluted by apparently redundant spills of intermediate results to the stack. On inspecting the assembly produced from the file to be attached, compare the code generated for matrix44f::transform_good and matrix44f::transform_bad. The former is 20 instructions and apparently optimal. However, it was only arrived at by prodding the latter version of the function (which does exactly the same thing but expressed more naturally, but results in 32 instructions) until the stack temporaries went away. It would be nice if both versions of the function generated optimal code and there doesn't seem to be any particular reason they shouldn't. Both versions' assembly contain the same expected numbers of shuffle, multiply and add instructions, the excess seems to all involve extra stack temporaries. [I'm not sure what the triplet codes on this form are. I'm using a gcc in Debian Etch gcc --version shows gcc (GCC) 4.1.2 20060901 (prerelease) (Debian 4.1.1-13); platform is a Pentium3. Sorry if the inline-asm component is a completely inappropriate thing to assign to.] -- Summary: SSE intrinsics hard to use without redundant temporaries appearing Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: minor Priority: P3 Component: inline-asm AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: timday at bottlenose dot demon dot co dot uk http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29756

Looks like this is mostly caused by:
union
{
__v4sf vecf;
__m128 rawf;
float val[4];
} _rep;
I will have a look more at this issue later tonight when I get home from work.

[Bug middle-end/28690] [4.2/4.3 Regression] Performace problem with indexed load/stores on powerpc
--- Comment #24 from bergner at vnet dot ibm dot com 2006-11-08 03:30
---
Ok, Anton hit another test case the last patch doesn't transform. It's
actually the same test case as in comment #13, except, int *base is now a
global variable rather than a function parameter.
int *base;
int indexedload(int len)
{
int i, sum = 0;
for (i=0; i len; i++)
sum += base[i];
return sum;
}
With this case, we get the following RTL generated for the load of *base into a
register:
;; base.1 = base
(insn 24 22 25 (set (reg:SI 129)
(high:SI (symbol_ref:SI (base) [flags 0x84] var_decl 0x400a6930
base))) -1 (nil)
(nil))
(insn 25 24 26 (set (reg/f:SI 128)
(lo_sum:SI (reg:SI 129)
(symbol_ref:SI (base) [flags 0x84] var_decl 0x400a6930 base)))
-1 (nil)
(expr_list:REG_EQUAL (symbol_ref:SI (base) [flags 0x84] var_decl
0x400a6930 base)
(nil)))
(insn 26 25 0 (set (reg:SI 124 [ base.1 ])
(mem/c/i:SI (reg/f:SI 128) [3 base+0 S4 A32])) -1 (nil)
(nil))
There seem to be two problems here. First, the mem/c/i:SI (reg/f:SI 128) seems
to be missing a MEM_POINTER attribute. I tracked that down to
rtl.h:MEM_COPY_ATTRIBUTES(LHS,RHS) not copying the MEM_POINTER attribute from
RHS to LHS. I added the code to do that, so the mem above does get the
MEM_POINTER flag set. However, the reg:SI 124 [base.1] is still missing the
REG_POINTER flag.
This second problem seems to be a problem in expand_one_register_var(tree var).
In this specific case, var seems to be a pointer type, but looks to be
artifical, so we skip the code that would have marked the reg rtx with the
REG_POINTER:
Breakpoint 4, expand_one_register_var (var=0x400a6d90) at

(gdb) p var-decl_common.artificial_flag
$8 = 1
If I clear var-decl_common.artificial_flag with the debugger and continue,
then we get the REG_POINTER flag set and the indexed load is generated with the
base pointer first like we want. Does anyone know why var above was marked as
artifical?

--- Comment #25 from pinskia at gcc dot gnu dot org 2006-11-08 03:35 --- (In reply to comment #24) Does anyone know why var above was marked as artifical? Yes because it is an compiler generated decl for the load of the global. The main reason why we don't mark the RTL for artifical decls is because we get still like: (int*)int_var Which causes problem. This is what PTR_PLUS_EXPR which I am creating helps solves. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28690
[Bug c++/29757] New: Non-ISO template qualifiers
Don't suppose you can deprecate this non-ISO C++ standard usage of the following proprietary G++ extensions: extern template int max (int, int); inline template class Fooint; static template class Fooint; ... as summarised at http://www.dis.com/gnu/gcc/Template-Instantiation.html. The problem with these is that they tempt some programmers to use them (a) without really understanding what they are doing as documentation is somewhat light on these extensions (b) in the mistaken belief it is standard C++, not a proprietary G++ extension (c) that non-G++ compilers ignore it, which they may or may not do in a predictable fashion. As an example, various versions of MSVC as well as other compilers can throw some odd errors. I have no problem with these being replaced with something like say: __attribute__((template_extern)) template int max (int, int); __attribute__((template_inline)) template class Fooint; __attribute__((template_static)) template class Fooint; This then does not give the illusion that these misuses of extern, inline and static with template declarations is proper C++.
