This means libgcc's emultls.o is not being linked in for some reason.

Let's avoid bad, it's ambiguous, and use incorrect/wrong or inefficient/poor.

As a suggestion, the test case added in commit
http://gcc.gnu.org/viewcvs?view=revision&revision=182768 should have the
additional two lines:

constexpr B b1 = A<10, 20, 30>::a;
constexpr B b2 = A<10, 20, 30>();

since these actually *cause* the ICE in the initial post.  (These two lines
were part of the initial post.)

Created attachment 26214

remember linkage of a function type (4)

I updated the patch to work with alias templates. I also hacked the library
enough to complete a --disable-bootstrap --enable-languages=c,c++ build. It
works well enough to play with it and see how buggy every code out there is...
I didn't implement conversions, -fpermissive or C casts are good enough as long
as this is just a toy.

[Bug fortran/51727] New: Changing module files

[mikael at gcc dot gnu.org]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51727

 Bug #: 51727
   Summary: Changing module files
Classification: Unclassified
   Product: gcc
   Version: 4.7.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mik...@gcc.gnu.org


Reported at http://gcc.gnu.org/ml/fortran/2011-12/msg00148.html

For a given fortran source file with module(s), repeated compilations may not
create always the same module file.  The URL above provides an example.

It seems that the symbols are not output in the same order.  In the example
provided, there are two module variants, the difference between them being that
one single symbol is at a different place in the file ( as reported at
http://gcc.gnu.org/ml/fortran/2011-12/msg00163.html ).

Possible causes:
 - unitialized memory, though valgrind reported nothing for me.
 - tree rebalancing.  Module I/O manages structures to be serialized using a
global tree ordered (when writing) by structures' addresses.  Could an
unrepeatable order just mean an unrepeatable address?.

The library should overload qsort, then the libitm/clone.cc change wouldn't be
needed

I think the change to tree.c should not be done as it is middle-end code.  That
should be in the C++ front-end specific code instead.  That is the middle-end
should not care about the difference between extern "C" function types and
extern "C++" ones.

[Bug c/39375] asm with a "=X" output overwrites the output

[pinskia at gcc dot gnu.org]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39375

--- Comment #6 from Andrew Pinski  2012-01-02

__asm__ ("xxx" : "+X" (sum));

Is most likely what you want to use.  This says the sum might be clobbered but
it might not be as the same value is used if it was not.

[Bug middle-end/39456] Functions/variables of a file in different named sections

[pinskia at gcc dot gnu.org]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39456

--- Comment #3 from Andrew Pinski  2012-01-02 
04:25:03 UTC ---
What about doing something like:
#define function_def(base_section, funname, RET, ARGS)
__attribute__((__section__(base_section ##funname))) RET funname ARGS

#define basesect "sect1_"

function_def(basesect, fct1, void, (void));

So you won't have a copy and paste error at all and it works without any real
changes to the compiler.
