Perhaps MEM_SIZE in second insn (originally first) being only 32-bit and not
64-bit is the bug.

--- Comment #4 from burnus at gcc dot gnu dot org 2008-09-09 12:15 ---
That algorithm looks bogus:
generate_local_decl (gfc_symbol * sym)
{
if (sym->attr.flavor == FL_VARIABLE)
{
/* Check for dependencies in the array specification and string
length, adding the necessary declarations to the function. We
mark the symbol now, as well as in traverse_ns, to prevent
getting stuck in a circular dependency. */
sym->mark = 1;
[...]
else if (warn_unused_variable
&& !(sym->attr.in_common || sym->attr.use_assoc || sym->mark))
It might be that sym->mark is somewhere reset, but I don't see where; if it is
not reset then it is clear that the message is not printed.
I think it got broken by Rev. 132756:
else if (warn_unused_variable
- && !(sym->attr.in_common || sym->attr.use_assoc))
+ && !(sym->attr.in_common || sym->attr.use_assoc || sym->mark))

[Bug middle-end/37356] [4.4 Regression] ICE in gsi_insert_seq_nodes_after, at gimple-iterator.c:222
--- Comment #9 from jakub at gcc dot gnu dot org 2008-09-09 13:03 --- Yes, it does (after all, it sometimes needs to insert statements even after stmt). Your patch is IMHO correct, but incomplete. There are 2 things that also need doing: 1) I think in while (!gsi_end_p (copy_gsi)) loop we want to iterate from the first stmt inserted from remaping orig_stmt, whether it is created by force_gimple_operand_gsi or gimple_regimplify_operands. ATM we just handle the last one. I guess we want 2 gimple_stmt_iterator's, one will keep advancing to the last stmt and one will be copy_gsi value when gimple_duplicate_stmt_histograms was called. 2) insert_init_stmt also calls gimple_regimplify_operands. It shouldn't create new gimplify_context, as gimple_regimplify_operands does that, and I'm not sure it needs to call find_new_referenced_vars (gimple_regimplify_operands calls mark_symbols_for_renaming and add_referenced_var on the temps). Certainly init_stmt needs to be inserted into the sequence before calling gimple_regimplify_operands though. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37356

[Bug c/37443] New: fast 64-bit divide by constant 32-bit
consider the code fragment:
uint64_t slow(uint64_t x) {
return x / 1220703125u;
}
This can be replaced by:
uint64_t fast(uint64_t x) {
uint32_t a = ((x >> 32) * 1270091284u) >> 32;
uint32_t b = ((x & 0xu) * 3777893186u) >> 32;
return ((x >> 32) * 3777893186ull + a + b) >> 30;
}
The 'fast' code runs 50% faster than 'slow'. However, removing the redundant
multiplies (see my earlier bug - fixed in 4.4 trunk) and tidying up storage, I
can use the following assembler to run nearly 100% faster than 'slow':
.p2align 4,,15
.globl _fast
.def_fast; .scl2; .type 32; .endef
_fast:
pushl %ebx
movl$1270091284, %eax
mull12(%esp)
movl$-517074110, %eax
movl%edx, %ebx
mull8(%esp)
movl$-517074110, %eax
movl%edx, %ecx
mull12(%esp)
addl%ebx, %ecx
popl%ebx
adcl$0, %edx
addl%ecx, %eax
adcl$0, %edx
shrdl $30, %edx, %eax
shrl$30, %edx
ret
NOTE: the 2 multipliers are derived using 96-bit arithmetic:
d = 1220703125u
-517074110 = 0xffe12e1342u = (((1u << 94) + d - 1) / d) >> 32
1270091284 = (((1u << 94) + d - 1) / d) & 0xu

[Bug middle-end/37380] [4.4 Regression] ../../gcc/libcpp/charset.c:1103: error: 'cvt.77.width' is used uninitialized in this function
--- Comment #9 from rguenth at gcc dot gnu dot org 2008-09-09 16:56 ---
The key to the problem seems to be a structure passed by value where the
target passes it as pointer and the struct is callee-copied. This gimplifies
to the correct
cvt.64 ={v} cvt;
D.6054_4 = cvt.64.width;
width_5 = (size_t) D.6054_4;
but somehow SRA completely messes up scalarizing the struct copy from the
parameter:
cvt$width_59 = cvt.64.width;
cvt$cd_60 = cvt.64.cd;
cvt$func_61 = cvt.64.func;
cvt.64$cd_62 = cvt$cd_60;
cvt.64$func_63 = cvt$func_61;
cvt.64$width_64 = cvt$width_59;
D.6054_4 = cvt.64$width_64;
width_5 = (size_t) D.6054_4;
where it removed the initialization of cvt.64. Which seems because of
2311 src = force_gimple_operand (src, &seq2, false, NULL_TREE);
cvt$width
cvt.width
(gdb) n
2312 gimple_seq_add_seq (&seq, seq2);
(gdb) call debug_generic_expr (src)
cvt.64.width
so we force-gimple-operanded cvt.width to cvt.64.width (but seq2 is empty).

At some point between 4.3 and 4.4 the error printed for "(EN)" has changed.

Except for the "w.d" it looks OK. Or is this simply a side effect of (a)? Reason for (b): As the "1" is not under the edit descriptor (but under the object belonging to the edit descriptor) it is nontrivial to see which edit descriptor is wrong. -- Summary: Diagnostic of edit descriptors, esp.

This is - unfortunate, because we cannot easily fix that. Looks like we have to add a new flag to gimplify_ctxp to avoid this replacement for later gimplification of operands. We can of course also disable scalarizing of variables with DECL_VALUE_EXPR, but that doesn't look right.

[Bug c/37448] New: gcc 4.3.1 cannot compile big function
After upgrading to gcc 4.3.1, I can no longer compile a function whose
source code is 0.7 Megabyte before preprocessing and 3.5 Megabyte after
preprocessing.
The function (named "testsuite") is just a long list of statements
essentially of form if(!condition){complain();exit();}
The behaviour is: CPU time goes to 100%, then RAM size grows to
1 Gigabyte, then swap space starts growing and CPU time goes to 10%.
On my previous gcc (4.2.something, I think), compilation went fine.
The problematic source can be found at http://logiweb.eu/grue/lgwam.c
The source only #includes standard headers.
The source is compiled thus:
gcc -ldl -o lgwam lgwam.c
To double check that optimization is off, I tried with -O0
which gave the same result as not using -O0.
I failed to find out how to fill in Host, Target, and Build
triplet. Sorry. Here comes the output from gcc -v:

[Bug fortran/37445] Host-associated proc not found if same-name generic is use-associated
--- Comment #4 from burnus at gcc dot gnu dot org 2008-09-09 18:44 --- Paul, sounds like a bug for you. * * * The problem is that gfortran calls the use-associated (generic or specific) procedure instead of the host-associated procedure. (The procedure is use-associated in the specification part of a module). If the procedure is USEd in the subroutine or in a PROGRAM, all compilers print an error. * * * I wonder whether the following is valid: module m2 use, only: s1 All compilers accept this. However, how to read then the following, assuming that s1 is also a host-associated procedure: MODULE M2 USE M1, only: s1 procedure(),pointer :: procptr => s1 (Note: "procptr => s1" is Fortran 2008 syntax; F2003 only allows "=> null()".) Actually, I would reject a program if "only:" is specified [or for "use m2, s1=>s2"], but I have not checked the standard, yet. -- burnus at gcc dot gnu dot org changed: What|Removed |Added CC||burnus at gcc dot gnu dot ||org Summary|incorrect error reported|Host-associated proc not ||found if same-name generic ||is use-associated http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37445

[Bug bootstrap/37424] [4.4 regression] IRA merge breaks Solaris/SPARC bootstrap
--- Comment #2 from ebotcazou at gcc dot gnu dot org 2008-09-09 19:17

Several files are miscompiled by the stage1 compiler, starting with c-decl.c.
Now if you take the preprocessed file c-decl.i and compile it with a cross on
Linux, the resulting code is OK (the differences are in offsets against FP).
The discrepancy comes from the second qsort in ira_sort_regnos_for_alter_reg:
/* Sort regnos according the slot numbers. */
regno_max_ref_width = reg_max_ref_width;
qsort (pseudo_regnos, n, sizeof (int), coalesced_pseudo_reg_slot_compare);
It is not stable and this is quite obvious by looking at the compare function:
/* Sort pseudos according their slot numbers (putting ones with
smaller numbers first, or last when the frame pointer is not
needed). */
static int
coalesced_pseudo_reg_slot_compare (const void *v1p, const void *v2p)
{
const int regno1 = *(const int *) v1p;
const int regno2 = *(const int *) v2p;
ira_allocno_t a1 = ira_regno_allocno_map[regno1];
ira_allocno_t a2 = ira_regno_allocno_map[regno2];
int diff, slot_num1, slot_num2;
int total_size1, total_size2;
if (a1 == NULL || ALLOCNO_HARD_REGNO (a1) >= 0)
{
if (a2 == NULL || ALLOCNO_HARD_REGNO (a2) >= 0)
return (const int *) v1p - (const int *) v2p; /* Save the order. */
return 1;
}
else if (a2 == NULL || ALLOCNO_HARD_REGNO (a2) >= 0)
return -1;
slot_num1 = -ALLOCNO_HARD_REGNO (a1);
slot_num2 = -ALLOCNO_HARD_REGNO (a2);
if ((diff = slot_num1 - slot_num2) != 0)
return (frame_pointer_needed
|| !FRAME_GROWS_DOWNWARD == STACK_GROWS_DOWNWARD ? diff : -diff);
total_size1 = MAX (PSEUDO_REGNO_BYTES (regno1), regno_max_ref_width[regno1]);

if ((diff = total_size2 - total_size1) != 0)

[Bug fortran/37445] Host-associated proc not found if same-name generic is use-associated
--- Comment #5 from burnus at gcc dot gnu dot org 2008-09-09 19:18 --- Thinking it over, I think the program is INVALID per "Two or more accessible entities, other than generic interfaces or defined operators, may have the same identifier only if the identifier is not used to refer to an entity in the scoping unit. Generic interfaces and defined operators are handled as described in section 16.2.3. Except for these cases, the local identifier of any entity given accessibility by a USE statement shall differ from the local identifiers of all other entities accessible to the scoping unit through USE statements and otherwise." (I couldn't find anything special about specification parts in modules - not that I expected to find something. The quote above is for Fortran 2003, but the same is true for Fortran 2008; I have not checked Fortran 90/95 but I do not expect a different result.) That the program is invalid solves a huge number of potential problems, some of which I eluded some in comment 4. I was about to ask at comp.lang.fortran, but decided that it is obvious enough that there is no need to do so. Note: I believe that already "subroutine putaline(...)" is invalid. -- Even though g95, NAG f95, ifort, Lahey, and openf95 accept it, but it is not the first time that a lot of compilers have the same bug. If you don't agree, please find the relevant section in the standard or ask someone to do so at comp.lang.fortran. gfortran is still buggy as it accepts the program (if one comments out "s3"). -- burnus at gcc dot gnu dot org changed: What|Removed |Added OtherBugsDependingO|32834 | nThis|| Keywords||accepts-invalid http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37445

[Bug tree-optimization/37449] New: calculix gets wrong answer for -O1 -ftree-pre -ffast-math
This probably won't be enough information to reproduce the bug, but I'm recording it now in case someone else runs into the same problem. Benchmark calculix from SPEC CPU2006 started failing with wrong results on powerpc64-linux with either -m32 or -m64 and "-O2 -ffast-math" with this patch: http://gcc.gnu.org/viewcvs?view=rev&rev=137631 r137631 | dberlin | 2008-07-08 16:11:06 + (Tue, 08 Jul 2008) It doesn't fail for i686-linux or x86_64-linux. With recent mainline and as of r140162 (although not at r137631) it also fails with "-O1 -ftree-pre -funsafe-math-optimizations". The only file affected by the problem is rubber.f, which is generating wrong results somewhere in lines 298-319. Moving that code to another function makes it work fine, of course, as does adding print statements in that code for al(1). This isn't a case of some values being a little off, they're massively different, based on adding print statements later in the code. I'll keep trying reproduce the problem with a smaller testcase. -- Summary: calculix gets wrong answer for -O1 -ftree-pre -ffast- math Product: gcc Version: 4.4.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org GCC target triplet: powerpc-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37449
