[Bug c++/39566] New: Optimization fails on templated iteration function
I tried to reduce the code to a minimum, so the example does no longer make
sense at all.
However, the point is, that the code is supposed to return half the count of
elements in a container (e.g. if the container holds 16 elements, the function
would return 16, if it holds 33 elements, the function would still return 16).
Compiled with -O0, things are alright. Using -O1 or -O2 breaks it and the
function returns 15 for a container with 32 elements.
Compiling with -DWORKS_OK, omitting the template, everything is fine.

--- Comment #5 from jakub at gcc dot gnu dot org 2009-03-27 11:09 --- Ah, I see. The problem is that rs6000_macro_to_expand sometimes calls cpp_get_token (when seeing a macro after vector token), and removes optionally some CPP_PADDING tokens and a NT_MACRO token (with PREV_WHITE set on it). This only affects vector, not pixel nor bool. Unfortunately, we can't expand vector to a macro defined as 'vector ' (without quotes), because that would mean infinite recursion. We could perhaps if macro_to_expand hook returns NULL set PREV_WHITE on the next token (on the libcpp side, as rs6000_macro_to_expand sees tokens as const cpp_token), or insert a CPP_PADDING token. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39558

--- Comment #2 from jakub at gcc dot gnu dot org 2009-03-27 12:38 --- This seems to be just a C FE problem, C++ FE compiling the exact same testcase gives the expected output (DW_TAG_lexical_block with DW_TAG_variable with DW_AT_external). So IMHO just the C FE should be fixed to handle it like the C++ FE and if there are gdb bugs, they should be fixed in gdb. -- jakub at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2009-03-27 12:38:16 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39563

I have to admit I didn't see it with an x86-64 compiler; perhaps the ppc64 port
is more complicated and requires more bitmaps.
I suspect, given the error message, that you built a 32-bit compiler and ran
out of memory space before you hit this problem.

Note, there is problem with infinite recursion, since a macro is temporarily
undefined when it is being expanded, as per the ISO C rules. I tried the
following patch:
2009-03-26 Michael Meissner
PR target/39558
* rs6000-c.c (rs6000_macro_to_expand): If the conditional macro is
not to be expanded, return the default definition which is the
macro defined as itself. This insures that the proper spacing is
put out if -save-temps or -E is used and the next token is an
identifier or macro.

And it works for the compiler, but then gcc.target/powerpc/altivec-27.c fails,
which is crafted to test various cpp pasting, etc. I like your idea about
inserting a CPP_PADDING token.
The other way to do it is to add support for conditional keywords, like I did
for the named address space stuff for the cell, and not abuse the preprocessor.

[Bug c++/39567] New: class member template function won't compile
% g++ -v
Using built-in specs.
Target: i386-pc-solaris2.10
Configured with: ../gcc-4.3.3/configure --prefix=/home/robind/local
--with-gnu-as --with-as=/usr/sfw/bin/gas --without-gnu-ld
--with-ld=/usr/ccs/bin/ld
Thread model: posix
gcc version 4.3.3 (GCC)
With this source file:
template
struct wom
{
T afunc();
};
struct foo
{
template
T bfunc(wom w)
{
return w.afunc();
}
};
I get this compilation error:
bug.cc: In member function 'T foo::bfunc(wom)':
bug.cc:12: error: expected primary-expression before '>' token
bug.cc:12: error: expected primary-expression before ')' token
Renaming the function at line 10 from bfunc to afunc makes the code compile.
Thanks,

--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17544&action=view)
gcc44-pr39563.patch
Untested fix.
The problem with this patch is that DW_AT_decl_file and DW_AT_decl_line of the
DW_AT_external DW_TAG_variable and DW_TAG_subprogram DIEs is wrong. Say for:
extern void abort (void);
int var = 1;
int
main (void)
{
int var = 2;
if (var != 2)
abort ();
{
extern int var;
extern void abort (void);
if (var != 1)
abort ();
{
int var = 3;
if (var != 3)
abort ();
{
extern int var;
extern void abort (void);
if (var != 1)
abort ();
}
}
}
return 0;
}
for all DW_AT_external DW_TAG_variable DIEs DW_AT_decl_line is 3 and for abort
DW_AT_decl_line is the last extern void abort (void) line.

[Bug rtl-optimization/34999] Fallthru crossing edges in partition_hot_cold_basic_blocks are not been fixed when the section ends with call insn
--- Comment #22 from ghazi at gcc dot gnu dot org 2009-03-27 16:37 ---
I still see failures in bb-reorg.c and pr34999.c on x86_64-unknown-linux-gnu:
http://gcc.gnu.org/ml/gcc-testresults/2009-03/msg02744.html
The error message is slightly different than what others have posted here. I'm
using "GNU assembler 2.17 Debian GNU/Linux" on the GCC compile farm:

These are the last C testsuite failures I get on this box. Perhaps we can
xfail them when we branch if it won't be fixed in time for 4.4?

--- Comment #4 from rguenth at gcc dot gnu dot org 2009-03-27 17:26 ---
The issue is that TER does not build large trees for the multiplications as
the factors are used multiple times (and come from memory). Thus the expander
does not see the widened multiplication and appearantly combine / lower-subreg
is not able to optimize this.
I think with expand-from-SSA we could enable this optimization during expand.
Simplified testcase:
long long foo (int i, int j)
{
return (long long)i * (long long)j * (long long)i;
}
because we CSE (long long)i we don't optimize this case. Disabling tree-level
CSE re-enables the optimizations: -fno-tree-fre -fno-tree-pre
-fno-tree-dominator-opts

I can't see how register usage and calling convention affect this.
As I said before, this behaviour bit me in a naked interrupt handler, with no
arguments and no return value.
I'm attaching a fixed test case where functions have no arguments and void
return type.

[Bug libstdc++/39569] New: Apparent memory corruption in std::stringstream after calling syslog()
Good afternoon, I've encountered a memory corruption problem writing to a stringstream after I've called syslog(), and I've been unable to find resolution. The short summary is that if my program makes a call to syslog(), then later during execution when I write >136 bytes of data into an std::stringstream object, the first 4 bytes in the stream get written as (or reset to) 0's. (If I write only 132 bytes into the object, the stream doesn't get corrupt. If I don't make the call to syslog(), the stream doesn't get corrupted.) I've created a small, self-contained test app that seems to reliably recreate the bug. I have tested (and recreated) it under Fedora 8 (x86_64), Fedora 8 (ppc), and Fedora 10 (i386). (I tried different compilers & platforms to try and rule out problems with a particular installation/configuration.) I can make available a .tgz file containing this test app upon request. My apologies in advance for any mistakes I make in submitting the bug... this is my first gcc bug, so I'm unfamiliar with the process.

Once you have the test_main executable, you can enter:
./test_main
to run the executable and 'log' to std out, which will work correctly... or
./test_main 1
to run the executable and log to syslog(), which will demonstrate the apparent
memory corruption.
I've tried to make the example as concise and helpful as possible... but if
I've missed anything, please don't hesitate to contact me.
I thank you very much for any help you can provide...

--- Comment #3 from steven at gcc dot gnu dot org 2009-03-28 01:02 --- Completely beyond you, how? What gcc does for darwin (and this is a hack, mind you), is basically replace the standard C99 builtins with darwin-specific ones. You have to do the same for NetBSD. See the following files in gcc/config/: * darwin.c * darwin-ppc-ldouble-patch.def The code in darwin_patch_builtin() changes the assembler name of the builtin function to a custom, darwin-specific version. E.g. cabsl has a PATCH_BUILTIN defines, so its DECL_NAME is the normal cabls name but its assembler name becomes _cabsl_$LDBL128. You need to do something similar (but probably less ugly) for NetBSD to make this work. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39570

[Bug fortran/39570] cabs and cabsf are named differently on NetBSD 5
--- Comment #4 from aran at 100acres dot us 2009-03-28 01:34 --- Subject: Re: cabs and cabsf are named differently on NetBSD 5 What is beyond me is how darwin_patch_builtings gets called. It looks like it is called from rs6000.c in rs6000_init_builtins via the macro SUBTARGET_INIT_BUILTINS. i386.c doesn't appear to have this infrastructure. I am not familiar enough with gcc internals to know what the impacts might be on other platforms if I start making changes here. Also, these renames are only for NetBSD 5. How do I detect the os version. The darwin example uses darwin_macosx_version_min. Is there a NetBSD analog?

--- Comment #5 from aran at 100acres dot us 2009-03-28 04:46 --- gmp-4.2.4 passes all test. mpfr-2.4.0 pass all except the tsprintf tests where my version returns 1.899347461279296875e+07 and the test expects 1,899347461279296875e+07 (notice the decimal point is a period instead of a comma). Considering that gmp is being told to raise 2 to the 268435472nd power, I don't think any system's allocator would work. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39571

FreeBSD seems to handle it. But, there is something wrong on your OS becuase huge(0) isn't 268435472.
