 This is really strange case. The patch should at most introduce extra inlining
 that naturally should not introduce undefined symbols.
 It is used as:
 sethi   %hi(_GLOBAL_OFFSET_TABLE_-(.LL363-.)), %o3
 or  %o3, %lo(_GLOBAL_OFFSET_TABLE_-(.LL363-.)), %o3
 callgnat__debug_pools__put_line, 0

 so it is passed to gnat__debug_pools__put_line.  Any idea what should be 
 there?
 It does not seem like variable, rather like code label. Can I have

Unfortunately not; you'd have to ask one of the Ada maintainers.  Eric
is on the Cc:, he might know.

 -fdump-tree-optimized (or perhaps better -fdump-tree-all) dumps?

Sure.  I couldn't attach it to the PR (1.8 MB even compressed with
bzip2), so I've put it at

A reghunt identified the responsible patch:

* tree-ssa-ccp.c (fold_const_aggregate_ref): Do not check STATIC flag.

Reghunting was a nightmare in this case since there was lots of
intermediate breakage which left the tree unbuildable for unrelated
reasons.

 yes, I'm testing a patch that checks the glibc version number -- I'm 
 reluctant 
 to try a more dynamic test as the whole point of these tests is to make sure 
 it 
 actually works, and disabling them in the face of failure seems unwise :)

If it requires support from GNU ld and/or the glibc ld.so, check for
that and disable the support on other platforms.

 I don't have access to sparc-sun-solaris2*, so I can't bootstrap it (but
 at most build a cross cc1).

Not even sparc-linux?  I very much doubt the bug is Solaris-specific.

 So please attach a testcase (easiest is probably in a non-bootstrapped
 tree run make check and pick a simple one that fails from the C testsuite).

Ok, I'll try to find one.

 Is sparc-sun-solaris2* a STRICT_ALIGNMENT target?  What's the clr instruction?
 Is it a store or a load?

Yes, cf. sparc.h.

clr and clrx store 0 (4 or 8 bytes) at the target address, requiring
natural alignment (which fails with your patch for the clrx case).

I've found one (in fact, it seems to be the only C one):

Without and with your patch, it shows the following difference, just
like the change that causes xgcc to get a SIGBUS:

clr and clrx are just synthetic instructions, the real thing can be
seen above: st resp. stx are stores of 4 resp. 8 bytes, and the %g0

%o0 isn't 8-byte aligned in this case, so the testcase dies with SIGBUS.

Compile with

 Presumably 163997 then.

Indeed: a C-only bootstrap on sparc-sun-solaris2.10 works as of rev
163996 and fails with 163997.

 This one actually shouldn't be IMHO delegimized, the setm44 value is just a
 temporary and thus it shouldn't hold any value interesting for debug info.
 Can you please attach -fdump-rtl-vartrack dump?

Done.  It took me some time because the files isn't created in the
working directory, but in the depths of gnu/javax/print/ipp/attribute ;-(  
I had to run jc1 under truss to find it.

 in *.expand looks correct, that var_location is %o0 instead of %g1 though.  So
 the bug is somewhere in between.  Would it be too large if you tarred up all
 dumps in between expand and split4?

Even compressed with bzip2, the file is 2.8 MB, way too big for
Bugzilla.  I've placed it at

 Rainer, do you think you could run make check in gcc/ subdir (assuming libjava
 was the last unbuilt library and say libstdc++/libgfortran/libgomp are already
 built) to see if this can be reproduced even on some C or C++ testcase? 

Sure, otherwise I'll start a fresh bootstrap with java excluded, which I
know finishes since I tried it with unrelated changes.

 (In reply to comment #15)
 (In reply to comment #13)

 OpenSolaris recently added support for the ARM Processor, so that adds a few
 more 'multi-lib modes' that need to be supported, along with the expanded 
 line

True, but irrelevant: each port only supports the multilibs it needs,
and not several different configurations with each from the set of
multilibs becoming the default.

 of SPARC Processors now being supported. The OpenSolaris Group also has a 
 'call
 for Ports', so in theory our mechanism _must_ be general enough to support 
 any
 possible Processor ...

The mechanism is, of course.

 Additional note for this RFE (which _might_ get re-opened, someday):

 OpenSolaris now runs on mips-sun-solaris2.11
 http://hub.opensolaris.org/bin/view/Project+mips/Tools

Far from it: there are minimal binutils and gcc patches yet, nothing
more.

 On Solaris 9:

 # of expected failures  7
 # of unsupported tests  28

 I wonder if there isn't a miscompilation somewhere though.

Seems so, yes.  A tree one rev. before Nathan's patch fails the same
way, so this isn't the culprit.  Reghunt in progress, though I'm not

Subject: Re:  [4.4/4.5/4.6 regression] Preprocessor ICE with -m64 and
--traditional-cpp

It occured to me that this is only failing for me with 32-bit cc1,
i.e. i386-pc-solaris2.11, sparc-sun-solaris2.11, mips-sgi-irix6.5, but
not alpha-dec-osf5.1 (which is 64-bit).

 atan2_1.f90 has failed on other platforms before too.  I think we just need:

  ! { dg-options -ffloat-store }

 or maybe this

  ! { dg-options -O0 -ffloat-store }

 in the test file.  Can you try that and see if it clears your problem. Add it
 right after the line that says ! { dg-do run }

 The first variant works like a charm: this way, we still iterate over
 several optimization levels, which would be defeated by the second one.

How should we proceed from here?  Should I formally propose the patch
above?

Jerry,

 Try this version of the test case and see what it does.  If this fails, I will
 send one instrumented a bit more.

this one works without problems, both 32 and 64-bit, at all optimization
levels (tested with

DEJAGNU=site.exp runtest --tool gfortran --srcdir $srcdir

 created.  But, as this PR lacks a testcase (well, the testcase depends on a
 proprietary header file not included here), it is hard to guess what's going
 on.

I could include the OpenSolaris header, which is licensed under CDDL,
but I've just been able to construct a minimal testcase:

$ cat include.c
#include stdlib.h
$ cat stdlib.h
#pragma redefine_extnamemkstemp64   mkstemp
$ ./cc1 -E -traditional-cpp ./include.c -o include.i -I . -m64
In file included from ./include.c:2:0:
./stdlib.h:1:0: internal compiler error: Abort

This should make it easier to find what's going on.  Unlike the original
test case from the GCC testsuite, this one fails even without -m64.

 Can't reproduce on x86_64-linux (and, #pragma redefine_extname seems to be
 handled on all targets, not just Solaris).

This seems to be extremely sensitive to command line parameters.  E.g. on
mips-sgi-irix6.5 it works (no ICE) with

$ cc1 -E -tditional-cpp include.c -o include.i -I .

When I add either -mabi=n32 or -mabi=64, cc1 aborts.

Similarly, on sparc-sun-solaris2.11:

$ cc1 -E -traditional-cpp include.c -o include.i -I .

ICEs

$ cc1 -E -traditional-cpp `pwd`/include.c -o include.i -I .

works.

Subject: Re:  -pthreads option with -shared does not cause libpthread.so to

I've found that the Sun Studio compiler behaves the same with its -mt
option and asked the maintainers about it:

http://mail.opensolaris.org/pipermail/tools-compilers/2010-June/001156.html

The relevance of that behavior has gone with the unified process model
in Solaris 10, and it's causing me trouble when implementing TLS support
for Solaris 8 and 9, so I'm going to fix this for 4.6.0, together with
that TLS patch.

 Right now, the only thing I can see make sense is numerically instability in
 the libm. Also, how are atan2f and atan2 defined in the system's math.h 
 header?
 Do they have simple prototypes? Are they actually macros?

The declarations are in iso/math_c99.h:

iso/math_c99.h:

extern float atanf __P((float));
extern float atan2f __P((float, float));

#if !defined(__cplusplus)
#pragma does_not_read_global_data(acosf, asinf, atanf, atan2f)
#pragma does_not_write_global_data(acosf, asinf, atanf, atan2f)

#if defined(__MATHERR_ERRNO_DONTCARE)
#pragma no_side_effect(acosf, asinf, atanf, atan2f)

 Does -ffloat-store change the outcome?  This looks to possibly
 be an excess precision problem and the difference between something
 in a register and main memory.

Indeed: with -ffloat-store, the test program only prints 0s.

[Bug libstdc++/44475] bunch of warnings of second definition on osf

19:19 ---
Subject: Re:  bunch of warnings of second definition on osf

I've regularly seen those warnings, but ignored them since I've found no
ill effect and the testsuite largely passes (which doesn't use the
static libstdc++.a anyway).

While I do have Tru64 UNIX sources, the compilation tools (including nm,
ar, and ld) are missing, so I cannot use that source to shed some light
on the warning, and binutils aren't an option yet since they don't
allow a bootstrap to finish.

Unless the reporter can provide evidence that this warning causes actual
problems, I'd suggest to close this as INVALID.

 First off this is not a regression; I ran into this issue back a couple of
 years ago with libjava requiring libgmp.

It sure is: you used to be able to bootstrap with a static, non-PIC
libgmp until this change went in, and now bootstrap fails.  If this is
not a regression, what is?

Subject: Re:  [4.4/4.5/4.6 Regression] gcc trunk 143562 - Testsuite - gfortran
failing tests that worked previously

I've now analysed this further: the test only fails at -O3.  The failure
is an abort in l.23:

  DDA1 = ATAN2 ((/(REAL(J1,KV),J1=1,10)/),
 $ REAL((/(J1,J1=nf10,nf1,mf1)/), KV))   !fails
  DDA2 = ATAN2 (DDA, DDA(10:1:-1))
  if (any (DDA1 .ne. DDA2)) call abort ()

Investigating with gdb, I find that only the 10th array element differs:

(gdb ) p dda1
$1 = (0.0996686518, 0.218668953, 0.358770669, 0.519146085, 0.694738269,
0.876058042, 1.05165017, 1.21202564, 1.35212743, 1.47112763)
(gdb) p dda2
$2 = (0.0996686518, 0.218668953, 0.358770669, 0.519146085, 0.694738269,
0.876058042, 1.05165017, 1.21202564, 1.35212743, 8.40779079e-45)

I've verified that atan2f is called with exactly the same input sequence
in both cases.  The problem is that at -O0 (and probably up to -O2),
atan2f is called 2 x 10 times as expected, and atan2f only appears twice
in the assembler output.

On the other hand, at -O3 the second time through, atan2f(1.0) isn't
called.  Instead, the loop is unrolled, but incorrectly, it seems: there
are now only19 calls to atan2f in the assembler output.

 The problem seems to have vanished, so eventually the fix can be backported
 (together with the typo fix in the configure script obviously).

Done: I've run toplevel configure and make configure-gcc on both
i386-pc-solaris2.11 (which has the new elf_getshdrstrndx) and
i386-pc-solaris2.10 (which only has the non-conformant version of
elf_getshstrndx) and got the expected results (and no error in
gcc/config.log), so I've check this in.

Should we ever receive more information for bootstrap/44079, we can
either fix the configure tests or document the required version of
elfutils libelf.

At least not in Autoconf 2.64.  I've found a single instance in the

 I have a deadline and do not have time to play with this.  The comparison
 function in df-scan.c, df_ref_compare, is not stable according to what has 
 been
 discussed in pr42157.   however, it does satisfy the definition of qsort in 
 the
 linux manuals.

I've no idea if the Solaris 8 (and IRIX 5) qsort violates ISO C90 here.

 if you need it to be that stable for those platforms, then change the last 
 line
 of df_ref_compare from return 0; to be 

 return (int)DF_REF_ORDER (ref1) - (int)DF_REF_ORDER (ref2);

Thanks, that's all I needed: bootstrap is past the ICE in the stage1
libgcc now, I'll let if finish and submit the patch, attributed to you,
once testing is complete.

   Using something like TARGET_SOLARIS is wrong: this is just a bug in older
 Sun

 I don't completely agree.
  - I regularly do cross builds.
What will you do for that? Assume the old version? I think so. Since the
 result works the same on all versions. So you might as well just do that for
 cross and native imho.

No, I just test if rep insn works or if rep; insn is required
instead and use the result of that test.  It works in both native and
cross environments.

  - I want to build a gcc on 2.10 that works on 2.9..er..well, that's not quite
 right. For that I'll build it on 2.9. But the cross build scenario is 
 relevant.

That's not going to work in the general case: the Solaris 10 gcc may
well use features that just don't exist in the Solaris 9 assembler
and/or linker, so you're out of luck.

  - Look at what Darwin/Macho does -- that is also only for older versions, but
 they just do it unconditionally. (Might be good to check for TARGET_64BIT
 though, since that probably implies a new enough assembler?)

This hardcoding is wrong in the general case, even if the Mach-O guys
did otherwise.  Why follow a bad example?  And why use implicit tests if
you can explicitly test for the feature (or bug) you're looking for?

 This is now documented in install.texi to deter people who think they 
 should  use solaris on Solaris 2.
 Thanks for fixing the DOCs, can we pull the code too (or ifdef it out for
 OpenSolaris) to avoid having code in gcc that is no longer supported.

This has nothing to do with OpenSolaris, just the fact that some target
libraries don't work with --enable-threads=solaris, while others work
just fine.  No real reason to pull it out, though I could be persaded to
do so given that there's no benefit in keeping it.

 This is an Enhancement (EG: I wish (someday in the future) that we had this

 feature exceeded the lack of available time to implement it (as Eric pointed
 out we may cross that line shortly).

But what's the *point* of having such a configuration, except as a prove

 As I've said before: please file *clear individual bug reports* for each 
 single
 issue you find.  Dealing with reports like this, with dozens of issues and 
 non-
 issues mixed, is close to impossible.

 I'll stick with comment #1 describes the Bug.

The beef of your report seems to be: I get errors from Sun ld linking
libgnat-4.4.so.  In my experience, this only happens when you re-run
make bootstrap in a completed build or re-start it after the build
failed at some point.  For some reason, the libgnat objects seem to be
rebuild without -fPIC, leading to the observed error.  Seems like a bug
in the Ada build system to me.

 Further comments were workarounds and to report a Flag Day on the Sun 
 Linker.

I don't think there is any flag day involved, this error just depends
very much on the circumstances of the build.

I simply used to remove the gcc/ada/rts{, rts_amd64} directories and a
couple of stamp files when I encountered this, though I haven't in a
long time.  Perhaps the build system error is gone now.

 What's the status of this bug?

I haven't checked anything before Solaris 10 yet (still have to set up
my test sustems), but mainline is fine since the native libelf can be
used.  I haven't pushed the libelf 0.8.12 patch upstream yet, but there
isn't much use if the native library can be used.

The 4.5 branch is still affected until the elf_getshdrstrndx has been
backported.  Btw., what's the status with Honza's problem with that?  I
haven't heard anything yet, but would like to have this sorted out
before backporting.

 This one appears to have fallen through the cracks. Reported exactly one year
 ago, and now accidentally shows up in my search because my brain believed we
 still live in 2009... Oh well.

I'll try to go through the Solaris bugs in the near future, but have
concentrated on getting the 4.5 release in shape until now.

 Rainer, could you see if you can confirm this one (with 4.4/4.5/trunk)?

I don't have a 4.4 tree around at the moment, but the testcase works
fine on both 4.5 and mainline *with a sparc-sun-solaris2.10* compiler.
The problem might be related to the sparc64-sun-solaris2.8
configuration, but I refuse to test that because I simply don't have the
manpower to double testing effort when a 32-bit default bi-arch compiler
handles this just fine.  I'd rather remove the sparcv9-sun-solaris2.*
configuration than deal with this.

 Could the warning: GMP header version 4.3 differs from library version 
 4.3.0.
 have something to do with the segfault?

I doubt that, actually, though I haven't checked GMP versioning in
detail.

Maybe Eric has a sparcv9 compiler around and can easily check this?

 --- Comment #10 from ebotcazou at gcc dot gnu dot org  2010-04-28 22:09 
 ---

 While the advantages of sparc64-sun-solaris2.* are limited, I don't think we
 should remove it now since it can handle more memory and 64-bit computing is
 becoming the norm.

I have no actual intention of doing so, although it increases the
complexity of the target headers.

 Similarly, I think adding a 64-bit compiler on x86 would be desirable.  And it
 would be faster than the 32-bit one because of the 64-bit ABI.  As a matter of
 fact, we already have the few required patches at AdaCore.

Patches have been floating around, and I'm sure I could get them into
shape.  My problem (apart from the same complexity problem as on SPARC)
isn't primarily cpu power of my testfarm, but rather the time it takes
to analyze and fix problems.  This is practically doubled if you have
two different configurations to test, and I simply cannot afford that,
given that this is a spare-time activity.  That's why I'm even opposed
to take patches, since than I'm forced to deal with issues as well.

Since the Sun Studio compilers are still exclusively 32-bit as wall, I
see no strong reason for GCC to be different.

14:24 ---
Subject: Re:  stabs debug info fails onIRIX 5.3

I don't think this is a gcc bug.  While the native IRIX 5 tools use
ECOFF debugging info embedded in ELF (mdebug), they don't know about
Stabs-in-ECOFF/mdebug which is a GCC extension which IRIX 5 gdb cannot
handle.  Therefore it seems to be more useful to use Stabs-in-ELF
instead of Stabs-in-ECOFF/mdebug instead, like gas on IRIX 6 does.

In fact, I've got a patch to gas to do so.  It seems like gas cannot
properly handle the case where ECOFF_DEBUGGING_INFO isn't a compile time
constant, but can change at runtime based on the -mdebug/-no-mdebug
switch.  Once this is properly tested, I'll submit it to the gas
maintainers and update this PR accordingly.

This should be

 mov%fs:0x0,%rax

instead.  As I said, garbage in, garbage out.  If you disagree, point me
at where the spec allows this.  Even if so, we should either fix (if
allowing other registers is a GNU extension to the base spec) or work
around (if it is a misunderstanding on Sun's part) the problem if
targetting Solaris: there are linkers in the field that behave as
observed, and generating code that causes binaries to crash isn't a good
option.

I don't think this is a good idea: this part of the testcase tests a

 Indeed it does: with that chance, a full bootstrap on alpha-dec-osf4.0f
 and alpha-dec-osf5.1b succeeded.

 Thanks for confirmation!  I would however like to proceed with rest of
 patch in order to fix the C testcase.  Unfortunately I was not able to
 reproduce the ICE on my machine neither at cross or by bootstrapping at
 random architectures available to me.
 Do you think you can gather at least some data about the ICE? (i.e.
 function name or so).  Looking through the patch I don't see any obvious
 mistakes.  It might be side effect of moving RTL generation of
 assembling alias, but that is needed to avoid RTL from being produced
 too early before visibilities are set.

Unfortunately, I've so far been unsuccessful in getting any debugger to
work properly on the gnat1 binary.  I've tried gdb mainline, but there's
the same error, and indeed gnat1 cannot properly be processed by either
objdump or stdump (a native Tru64 UNIX tool to dump symbolic debug
information).  This seems to partially be a problem with the bootstrap
compiler (gcc 4.4.2 in my case), though: the gnat1 from my last
successful bootstap can at least be processed by stdump, though gdb 7.0
still SEGVs on it ;-(

I could try another mainline bootstrap, though: maybe I'll be more lucky
this time or be able what causes gdb to crash.

Which patch exactly would you like me to test?  Are the ipa.c and
varasm.c changes here

 I have (locally!) rolled back the change to ipa.c in r154121 as suggested and
 successfully built a compiler which successfully compiles the test case in
 p.txt. Will that be an adequate basis for a patch to resolve this PR for 
 4.5.0?

I think so: I've just rolled back the broken checkins, which allowed a
all,ada bootstrap to succeed on alpha-dec-osf{4.0f, 5.1b}.  I've
submitted the patch at

Subject: Re:  64-bit null_pointer_deref1 gnat.dg test consumes all available

 Somewhat expected, see the comment in the test.  A patch to disable it on this
 platform (sparc*-*-solaris2.11) is pre-approved.

I've just installed that since the bug hit me again and I've not yet
succeeded in the investigation.

 The failure very likely means that the 64-bit pattern matching code of the
 fallback routine in config/sparc/sol2-unwind.h misbehaves for Solaris 11. 
 Unfortunately, I don't have access to any Solaris 11 machine so I cannot fix.

I've checked __sighndlr in the Solaris 11 64-bit libc.so.1 against
sol2-unwind.h (sighndlr_pattern), and they are identical.

 To debug this, you need to recompile libgcc at -O0 -g and put a breakpoint on
 sparc64_fallback_frame_state from within the debugger; it will be hit once you
 resume execution after the SIGSEGV.  What happens from that on?

Unfortunately, it doesn't hit:

(gdb) b sparc64_fallback_frame_state

So I'm sort of stuck.  dbx doesn't allow me to set a breakpoint in

 I'm now running a C-only bootstrap with that patch on mips-sgi-irix5.3.
 Your previous patch allowed a full bootstrap to finish without a

That bootstrap finally completed, so the bug is definitely gone on IRIX

 I cannot see any point in retaining this PR against the gfortran target.

 I am marking it, especially in light of Rainer's remarks, as WONTFIX.

Ok with me.  I had meant for a long time to identify which changeset
broke linking the O32 libgfortran.so.  In the meantime, I've been
testing IRIX 6.5 with the O32 multilibs disabled globally.  But when I
recently retried bootstrap with all three multilibs and gas 2.20,
everything worked without problems.

So obviously this is all very fragile, and I may decide to deprecate the
IRIX 5 and O32 IRIX 6 ports in the future, should this problem come up
again.

 The testcase works on i?86.

Same for a i386-pc-solaris2.10 - alpha-dec-osf4.0f cross compiler.
This will make reghunting much slower.  I've last successfully

 Can you please add a check before the qsort call (tree-sra.c, line
 1407) whether all pointers in the access_vec seem OK or whether it is
 SRA that passes the invalid pointer to qsort?  Nothing fancy,
 something as stupid as the loop below should do:

 for (i =0; i  access_count; i++)
   gcc_assert (((unsigned) VEC_index (access_p, access_vec, i))  0x1000);

 If it passes I can't see any other explanation but a bad qsort.  If it
 doesn't we'll need to figure out how the bad pointers get there.

It seems that the qsort is broken (although I haven't found any report
about qsort on IRIX 5.3 yet).  Anyway, I've added a slightly modified
qsort from glibc to libiberty (which won't work due to license
differences, I suppose, but maybe newlib is an option), which allowed
the bootstrap to continue.

I'll later check (either with the code above or with gdb watchpoints)
what is causing the corruption.

Subject: Re:  Cannot build gcc: gthr-default.h:466: error: '__mutex' was not

 The #c4 patch looks wrong, instead of that you should IMHO just not use UNUSED
 macro on __gthread_mutex_destroy argument.  It is perfectly fine on
 __gthread_key_delete.

You're right, of course.  I should have looked closer.  Testing and
comparison with pthread results found two other bugs, one of which I
could already fix in gthr-solaris.h.  I've tried to debug the other
(objc) testcase, but gdb 6.6 cannot fully handle it, and I couldn't yet
get a gdb 7.0 to debug a 64-bit binary.

Given that this is a bootstrap failure, I'll submit and install the fix
now and check the remainder later.

 Is it better to let configure guess about thread model on OpenSolaris x86 
 32bit
 build = snv_126?

Sure: the default should be fine unless you have specific reasons to
prefer UI threads instead.  This has nothing to do with OpenSolaris in
any way, but is true for any recent Solaris 2 release.

Unfortunately, the problem does not reproduce in such a cross compiler,
so I'll have to either start a native reghunt or find a way to debug the
