[Bug c/37079] New: cannot find -lgcc_s

[jayk123 at hotmail dot com]

gcc 4.3.1, slightly patched to fix problems, binutils 2.18, gmp, mpfr


build=i686-pc-cygwin
host=target=sparc64-sun-solaris2.10


after first building/installing
  build=host=i686-pc-cygwin, target=sparc64-sun-solaris2.10


I thought -disable-multilib would simplify things and therefore fix them.
I don't believe this occurs with sparc-sun-solaris.
The file does exist, it just isn't found.


The cross tools installed:


$ ls /usr/local/lib/gcc/sparc64-sun-solaris2.10/4.3.1/

$ ls /usr/local/lib/gcc/sparc64-sun-solaris2.10/4.3.1/sparcv9/

libgcc_s.so  libgcc_s.so.1


well, since I use -disable-multilib, keeping "pure separate"
sparc-sun-solaris2.10
and sparc64-sun-solaris2.10, I can workaround just by copying/linking/moving
libgcc.so*.

[Bug debug/37022] [4.4 regression] internal compiler error: in compute_barrier_args_size

[jakub at gcc dot gnu dot org]

--- Comment #7 from jakub at gcc dot gnu dot org  2008-08-11 12:09 ---
Sorry, I can't reproduce the first issue with a x86_64-linux -> i?86-darwin
cross on the provided preprocessed testcase, tried many different
-march=/-mtune=
options as well as -f{,no-}asynchronous-unwind-tables.  What tuning do you use?
 What preferred stack size?

The later C testcase I can reproduce, but here the testcase has a frame pointer
(insn/f 38 37 39 pr37022.c:4 (set (reg/f:SI 6 bp)
(reg/f:SI 7 sp)) 47 {*movsi_1} (nil))
so I must say I don't understand at all why we generate any
DW_CFA_GNU_args_size
directives.  I believe the unwinder won't use them anyway, as in
uw_install_context_1
if (!_Unwind_GetGRPtr (current, __builtin_dwarf_sp_column ()))
the condition is false (sp is saved in bp).  For the -fno-a-u-t we check
cfa.reg:
if (!flag_asynchronous_unwind_tables && cfa.reg != STACK_POINTER_REGNUM)
but not so for the -fa-u-t case.

[Bug c++/36478] [4.3/4.4 regression] warning not emitted when code expanded from macro

[manu at gcc dot gnu dot org]

--- Comment #3 from manu at gcc dot gnu dot org  2008-08-11 12:32 ---
(In reply to comment #2)
> void  
> foo ()
> {
> #define WARNS while(0)
> #define DOES_NOT_WARN while(0); 
> WARNS; // { dg-warning }
> DOES_NOT_WARN;

I don't think we want to warn here. Even if we have the right location of ')',
this would be hard to warn. How do you distinguish?

DOES_NOT_WARN;
DOES_NOT_WARN/**/;

That said, I don't think tracking the end of the macro is a good idea either.
It just moves the problem around. Another workaround would be to not check
close_paren.column + 1 == semicolon.column since it is the next token and
before the semicolon there is no whitespace. The only problem is if there is a
comment, such as while(0)/**/; and we have no way to track that, have we?.

For a proper fix, we need at least 2 locations for each token that comes from
an expansion. The place where the token really appeared and the place where it
ended up. However, this is not trivial. We need either to encode such
information in 1 location_t number somehow or to encode it in the token.

The updated patch is attached (with instrumentation code present but

[Bug c/36556] OpenMP: incorrect 'not specified in enclosing parallel'

[jakub at gcc dot gnu dot org]

--- Comment #3 from jakub at gcc dot gnu dot org  2008-08-11 13:09 ---
If you mean the default(none) examples (in OpenMP 3.0 that's A.28), then no,
those testcases don't explicitly say it is ok to have the firstprivate clause
with a var not explicitly mentioned in the parallel's clause, it has neither OK
nor Error there, but as it already said an Error for using y I guess it doesn't
add an comment for it.

s is referenced in the parallel construct, see 2.9.1.1:
"Specifying a variable on a firstprivate, lastprivate, or reduction clause of
an enclosed construct causes an implicit reference to the variable in the
enclosing construct. Such implicit references are also subject to the following
rules."
and 2.9.3.1:
"The default(none) clause requires that each variable that is referenced in the
construct, and that does not have a predetermined data-sharing attribute, must
have its data-sharing attribute explicitly determined by being listed in a
data-sharing attribute clause."
Whether the reference is explicit or implicit is irrelevant for 2.9.3.1.

[Bug c++/35158] g++ does not compile valid C++ for loops with -fopenmp

[jakub at gcc dot gnu dot org]

--- Comment #9 from jakub at gcc dot gnu dot org  2008-08-11 13:14 ---
To answer c#7, that's what would (and does) happen for autoparallelization.
But OpenMP is explicit parallelization, if you don't preceede for (...; ...;
...) ... construct with #pragma omp {,parallel } for, nothing will warn nor
error on it.  But if you have the pragma there and request OpenMP pragmas to be
recognized, then the program must not only be valid C++ (or C or Fortran), but
also valid OpenMP code, so just warnings aren't appropriate.

The fact that the function returns the vector is not an essential part of the
test; the return value of the load function just needs not to be optimized out
as unused.  So changing the test for broader compatibility is fine as far as
I'm concerned.

[Bug other/37080] New: vasprintf in libiberty fails for %llu on solaris

[mark at easterbrook dot org dot uk]

vasprintf(buffer, "%llu %s", ...)

The code is:
  while (strchr ("hlL", *p))
++p;
  /* Should be big enough for any format specifier except %s and
floats.  */
  total_width += 30;
  switch (*p)
{
case 'd':
case 'i':
case 'o':
case 'u':
case 'x':
case 'X':
case 'c':
  (void) va_arg (ap, int);
  break;


It is ignoring the ll and processing the long long argument as an int.
Unfortunately this leaves the va-list pointer in the wrong place (4 bytes out I
think). The next argument is %s, so it takes the next thing, treats it as a
pointer, and strlen() it, but this is an invalid pointer (it is really the
second part of the long long) so it seg faults.

The above code needs to count l prefixes and use va_arg(ap, long) or va_arg(ap,
long long) as appropriate.

(The h is safe as a short will be promoted to int in the variable arg list,
just the l prefix needs fixing).

Additional patch on top of sp=reg.patch patch, which should fix the SH4 case -
the simplistic stack_adjust_offset wouldn't see the adjustments in pop
instructions, only push instructions.  I'm not sure if it is enough to do it
this way, or whether for_each_rtx shouldn't be called instead to find all
embedded MEMs with {PRE,POST}_{INC,DEC,MODIFY} operands on sp register.

[Bug middle-end/37014] [4.2/4.3/4.4 Regression] internal compiler error: in expand_expr_real_1, at expr.c:8760

[jakub at gcc dot gnu dot org]

--- Comment #7 from jakub at gcc dot gnu dot org  2008-08-11 18:38 ---
I think the options are:
1) handle TRUTH_{AND,OR}IF_EXPR in expand_expr again (revert part of Paolo's
   2004-08-09 expr.c "dead" code removals) - while these aren't present
   in GIMPLE nor can be created by TER, they can be created by folding during
   expansion.  Maybe even COMPOUND_EXPR could be handled there and all the
   ugly hacks builtins.c does to work around this could be removed.
2) have a special flag for fold-const.c, set during expansion, that would
   preclude certain kinds of folding (e.g. creation of the trees that aren't
   handled by the expander)
3) have expand's special versions of the various fold* routines, look for the
   unhandled trees in what it creates and either fail to fold them, or
transform
   to something else.

IMHO 1) would be probably easiest to implement, 3) too ugly to live, 2)
possible.

The darwin -m64 failures are then the same problem, cross-jumping of noreturn
calls between different level of stack depths.
I've been wrong about DW_CFA_GNU_args_size being useless for cfa.reg !=
STACK_POINTER_REGNUM, while such directives won't ever be used by the libgcc
unwinder, they might be used by debuggers to set correct value of stack
pointer,
and therefore such directives aren't useless and so we should avoid
crossjumping
in that case.  Not sure how to detect that in crossjumping code though.

I think in gimplify_modify_expr_rhs
  case VAR_DECL:
/* If we're assigning from a constant constructor, move the
   constructor expression to the RHS of the MODIFY_EXPR.  */
if (DECL_INITIAL (*from_p)

&& !TREE_THIS_VOLATILE (*from_p)
&& TREE_CODE (DECL_INITIAL (*from_p)) == CONSTRUCTOR)
we should be checking TREE_READONLY (*from_p) rather than TYPE_READONLY
(TREE_TYPE (*from_p)), as when the type is read-only, but the VAR_DECL is not,
the initializer in DECL_INITIAL might be still incomplete and needing runtime
initialization.

[Bug bootstrap/37086] New: Cross-compilers built with GCC 3.4 do not work

[drow at gcc dot gnu dot org]

Building libgcc, I get:

/scratch/dan/mips-nonpic-upstream/src/gcc-mainline/libgcc/../gcc/unwind-pe.h:
In function 'size_of_encoded_value':
/scratch/dan/mips-nonpic-upstream/src/gcc-mainline/libgcc/../gcc/unwind-pe.h:78:
internal compiler error: tree check: accessed elt 7 of tree_vec with 5 elts in
find_switch_asserts, at tree-vrp.c:4346

/scratch/dan/mips-nonpic-upstream/src/gcc-mainline/libgcc/../gcc/unwind-dw2.c:1257:
internal compiler error: tree check: accessed elt 9 of tree_vec with 7 elts in
find_switch_asserts, at tree-vrp.c:4346

If I recompile tree-vrp.o with -O0, then libgcc compiles OK.

Joseph suggests this came in at the time of the tuples merge.  If possible, it
would be nice if we could avoid the problematic construct...

The code in question is:

  /* If there are multiple case labels with the same destination
 we need to combine them to a single value range for the edge.  */
  if (idx + 1 < n
  && CASE_LABEL (cl) == CASE_LABEL (TREE_VEC_ELT (vec2, idx + 1)))
{
  /* Skip labels until the last of the group.  */
  do {
++idx;
  } while (idx < n
   && CASE_LABEL (cl) == CASE_LABEL (TREE_VEC_ELT (vec2,
idx)));
  --idx;

When we reach the outer if, idx == 3 and n == 5.  We go around twice, but idx
goes up to 7.

It looks like a loop optimization issue:

0x84fa0fd :   lea0x2(%edi),%esi
0x84fa100 :   mov-0x40(%ebp),%edi
0x84fa103 :   cmp-0x3c(%ebp),%edi
0x84fa106 :   mov%esi,-0x40(%ebp)
0x84fa109 :   jb 0x84fa080

0x84fa10f :   mov-0x38(%ebp),%ecx
0x84fa112 :   dec%esi
0x84fa113 :   mov%esi,-0x40(%ebp)

-0x40(%ebp) is idx, and idx+1 is in %edi before the above code.

Specifically, I did a binary search that determined the tuples merge as

[Bug c++/37087] New: Segfault on compiling template defined in wrong namespace.

G++ reports a segmentation fault when compiling the code below.

Hmm, I don't think default parameters are taken into account with function
pointers.   I think this was a GCC "undocumented extension" (aka bug) that was
fixed in 4.3.

I've confirmed that this patch gets rid of the ICEs for the test
case in #7 and the original libjava build failure on SH4, though
libjava fails to build at the another place on SH4.
Here is a reduced test case:

typedef union {
  double value;
  struct { unsigned int lsw, msw; } parts;
} ieee_double_shape_type;

double
foo (double x)
{
  unsigned int hx, lx;
  ieee_double_shape_type u;

  u.value = x;
  hx = u.parts.msw;

  if (hx >= 0x40862E42)
{
  if (hx >= 0x7ff0)
{
  u.value = x;
  lx = u.parts.lsw;

  if (((hx & 0xf) | lx) != 0)
return x+x;
}
}

  return x;
}

I'd like to attach .206.shorten dump for this.

[Bug c/37090] New: optimization breaks code in manually unrolled loop

[michael+gcc at stapelberg dot de]

Except for -O0, all levels of optimization make the same mistake on the
attached files.

Compile them (for example) with:
gcc -O2 sp.c mybyte.c -o sp

On gcc 4.3.1 (vanilla, self-compiled, also applies to the gentoo standard one),
this outputs "123456789abcd" instead of "123456789abcdef" (gcc 4.1.2 for
example).

When removing the fourth line of the loop, it works.

I could reproduce this also on debian.

Just in case you care, the code is ripped out of fefe's libowfat.

I am not clear of you but this rtl is necessary for our stack realign proposal.
During we designed and implemented the stack realign proposal we didn't intend
to affect the existing way that DW_CFA_GNU_args_szie works.

Here's the file:

At this stage, the newly built gcc is used to build the crt, so it's the stage

Preprocessed source added as attachment.  Also note that the bootstrap gcc was
built with cygwin's gcc, which is a modified 3.4.4.

This failure comes up whenever GCC 3.4.x is used to build GCC 4.4 on Windows. 
I'm not sure if it affects any non-Windows targets.

To clarify, GCC 3.4.x miscompiles GCC 4.4 when not being bootstrapped.  A
normal bootstrap won't show this failure, but a cross build or
--disable-bootstrap will.

The bug is still present on the 4.3 branch as of 2008-08-11 (with both the C
and C++ frontend).

As Andrew Pinski pointed out, we suppress ICEs after regular errors.
You have to configure the compiler with --enable-checking to see the real ICE.
