--- Comment #3 from ian at airs dot com 2007-04-27 04:52 --- Created an attachment (id=13453) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13453&action=view) Proposed patch This is an interesting test case. It turns out that VRP has always consistently assumed that TREE_TYPE (TYPE_MIN_VALUE (t)) == t. The assumption turns up in == comparisons against TYPE_MIN_VALUE (and TYPE_MAX_VALUE). Those == comparisons are normally valid because we hash integer constants so that they are all the same. The hash includes the type. So when TREE_TYPE (TYPE_MIN_VALUE (t)) != t, the equality will actually never hold, and VRP will do the wrong thing. This patch simply ensures that the equality holds. I'm testing it now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31710

--- Comment #3 from rguenth at gcc dot gnu dot org 2007-04-26 23:22 ---
That's probably exposed by Honzas struct/array_ref folding changes.
we have after inlining
p_4(D) = &arr;
D.1631_5 = p_4(D) + -4B;
n.0_6 = 4;
D.1633_7 = n.0_6 * 4;
D.1634_8 = (DWORD *) D.1633_7;
D.1635_9 = D.1631_5 + D.1634_8;
D.1636_10 = *D.1635_9;
and fold the reference to arr[1073741823] from within
maybe_fold_offset_to_array_ref. In the index calculation
if (TREE_CODE (elt_size) != INTEGER_CST
|| div_and_round_double (TRUNC_DIV_EXPR, 1,
TREE_INT_CST_LOW (offset),
TREE_INT_CST_HIGH (offset),
TREE_INT_CST_LOW (elt_size),
TREE_INT_CST_HIGH (elt_size),
&lquo, &hquo, &lrem, &hrem)
|| lrem || hrem)
return NULL_TREE;
idx = build_int_cst_wide (TREE_TYPE (offset), lquo, hquo);

[Bug libstdc++/31717] libstdc++-v3 - Make fails with: ./c++locale.h:69: error: '__locale_t' does not name a type
--- Comment #2 from rob1weld at aol dot com 2007-04-26 21:33 ---
Thank you Paolo Carlini.
Previously I _did_ let ./configure guess (on successful builds) but _this_
_time_ I used _exactly_ the same ./configure parameters as I did for Linux (to
duplicate the GCC compiler for both systems [and the success]).
I was just checking my stdc++.ii file (for a problem with line # _69_ and this
is what it looks like:
# 67
"/cygdrive/c/gcc-4_2-branch-build/i686-pc-cygwin/libstdc++-v3/include/bits/c++locale.h"
3
namespace std {
typedef __locale_t __c_locale;
Previous to that part (in the .ii file) there is nothing to say what __locale_t
is so it is as though it were blank (IE: the line would read: "typedef
__c_locale;" and thus fail).
I guess this bug would be fixed if the 'root' ./configure script did not allow
one to use "--enable-clocale=gnu" on this platform (and kindly suggested to
ONLY use --enable-clocale=generic).
If that is the correct solution then I would consider this resolved _after_ the
./configure script is changed.
Thanks for the quick response - I might have had a lot of trouble tracking that
down. Now to re-make the compiler (and just [OF COURSE] when the build was
nearly finished (crying)). :)(Used to it.)

When compiling code that contains UTF-8 identifiers using the -gnatW8 and -gnatiw switches, the compiler gives the following error: "a-numeri.ads:25:04: illegal wide character" This line contains the bracket notation version of the "pi" symbol in the Ada.Numerics library. The -gnatWx switch is supposed to add additional recognized character encodings to the default bracket notation encoding. The bug is that the -gnatWx switch (together with -gnatiw) seems to disable the bracket notation, causing a compile error on a file in the standard library that uses that encoding method. -- Summary: Incorrect handling of -gnatW8 and -gnatiw switches Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: david dot smith at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31718
[Bug fortran/31711] rhs array is changed while assiging to same lhs array
--- Comment #5 from burnus at gcc dot gnu dot org 2007-04-26 20:50 ---
> This can be seen in the file (result.dat) generated by the program.
I missed that part. Reduced test:
program laplsolv
IMPLICIT NONE
integer, parameter :: n=10
double precision,dimension(0:n+1,0:n+1) :: T
double precision,dimension(n) :: tmp1,tmp2
integer :: i
T=0.0
T(0:n+1 , 0) = 1.0
T(0:n+1 , n+1) = 1.0
T(n+1 , 0:n+1) = 2.0
tmp1=T(1:n,0)
T(1:n,1)=(T(0:n-1,1)+T(1:n,1+1)+tmp1)
do i = 1, n
print '(20f4.1)', T(i,1)
end do
end program laplsolv
The "T(1:n,1)=(T(0:n-1,1)+T(1:n,1+1)+tmp1)" get wrongly translated as:
{
int8 S.4;
S.4 = 1;
while (1)
{
if (S.4 > 10) goto L.5;
t[S.4 + 12] = (t[S.4 + 11] + t[S.4 + 24]) + tmp1[S.4 + -1];
S.4 = S.4 + 1;
}
L.5:;
}
It should be something like:
for(int i = 1; i < 10; i++) {
t.1[i + 12 ] = (t[S.4 + 11] + t[S.4 + 24]) + tmp1[S.4 + -1];
for(int i = 1; i < 10; i++) {
t[i + 12] = t.1[i + 12]
That is: First the right-hand side needs to be evaluated before the lhs is
written.

I'm really interested why this happens only here and not Janne's or SUSE's system. Anyway, I reduced the test case to: 37 aermod2_RESINI.f90 - reduced RESINI subroutine 14 aermod2_prog.f90 - reduced PROGRAM aermod 720 aermod2_main.f90 - the full MAIN module 15410 aermod2.f90 - the remaining part of aermod Compared with initially 26993 lines that's not too bad, but still way too big :-( If I compile everything with the previous options except of aermod2_RESINI.f90 it does not crash. Removing the SAVE in RESINI also gets rid of the crash. Any idea how to proceed except of trying to reduce the 15410 lines? Can anyone else reproduce this (maybe it is only visible using valgrind on other systems)?

[Bug c/31712] New: no warning on implicit cast from int to pointer
Mixing up variables when working with strings does not trigger a warning.
Example:
int main(void)
{
int plen;
char *ptr;
plen[ptr]='\0'; /* (char*)'th element of an int */
return 0;
}
in line 6, plen[ptr]='\0';, plen is implicitly casted to a pointer and ptr is
implicitly casted to an unsigned. At least when casting the int to a pointer,
there should be a warning.
This behavior can be reproduced in, at least, versions 2.95, 3.2.3 and 4.1.2 of
gcc. Adding -Wall -g -ansi -pedantic -std=c99 does not help.

--- Comment #2 from ubizjak at gmail dot com 2007-04-26 11:20 ---
This bug is due to my commit:
http://gcc.gnu.org/ml/gcc-cvs/2007-04/msg00657.html
This patch introduces "vec_unpacks_hi_v4sf" and "vec_unpacks_lo_v4sf" to sse.md
an these patterns trigger generic vectorizer problem (related to multiple data
types in the loop having VEC_UNPAC_HI/LO and not related to convesions at all)
in alignment handling.
Polyhedron crashes in:
Dump of assembler code from 0x804def2 to 0x804dff2:
>> 0x0804def2 :movapd %xmm1,(%eax)
0x0804def6 :cvtps2pd 0xff48(%ebp),%xmm0
0x0804defd :movapd %xmm0,0x10(%eax)
0x0804df02 :add$0x20,%eax
0x0804df05 :cmp%edi,%ebx
Dorit has confirmed the problem and she is already testing a fix.
The C testcase that crashes (you need -O2 -msse2 -ftree-vectorize [-m32]) to
trigger the problem, as "z" needs to be aligned to 8 bytes:
--cut here--
float x[256];
void foo(void)
{
double *z = malloc (sizeof(double) * 256);
int i;
for (i=0; i<256; ++i)
z[i] = x[i] + 1.0f;
}
int main()
{
int i;
for (i = 0; i < 256; i++)
x[i] = (float) i;
foo();
return 0;
}
--cut here--
If an urgent fix is needed, then simply rename "vec_unpacks_hi_v4sf" to
"*vec_unpacks_hi_v4sf".

[Bug fortran/31711] Data parallel code gets transformed to serial
--- Comment #2 from thobes at gmail dot com 2007-04-26 10:58 ---
Data parallel vector operations doesn't seem to get computed correctly in all
cases. Simple cases such as:
program test
integer,dimension(0:9) :: T
integer:: i
T(0:9) = 0
T(0) = 1
T(1:9) = T(1:9) + T(0:8)
do i=0,9
write(unit=*,fmt=*) 'T(',i,') = ', T(i)
end do
end program test
seem to work, but more complex ones does not (see attached file).
This has been tested on a x86 MacBook.

So the range in an semi-old (3 days) compiler, we get is:
D.1602_2: VARYING
D.1602_3: [-32768, -32768] EQUIVALENCES: { D.1602_2 D.1602_8 } (2 elements)
D.1603_4: [-INF(OVF), -32768] EQUIVALENCES: { } (0 elements)
D.1602_8: [-32768, -32768] EQUIVALENCES: { D.1602_2 } (1 elements)
Well obviously the recent patch to tree-vrp.c (which was also applied to the
4.2 branch) caused this failure as we are checking for overflow in some cases.
I always said the patch should never have been applied to the 4.2 branch
without a lot more testing.

These constraints are wrong. You need:
__asm__ __volatile__ ("fptan; fdivp;fchs;" : "=t" (tmpB) : "0"(r) : "st(1)");
Also note that tmpB is unused, as you rewrite it in next statement.

I've confirmed that the test case fails also on trunk.
sh.c:output_stack_adjust tries to find a register for a constant
to unwind the frame and wrongly finds a frame register itself
in the problematic case. I'm testing the attached patch.
