Libiberty: POSIXify psignal definition

Libiberty: POSIXify psignal definition

[Corinna Vinschen]

[Please keep me CCed, I'm not subscribed to gcc-patches.  Thank you]

Hi,

the definition of psignal in libiberty is

   void psignal (int, char *);

The correct definition per POSIX is

   void psignal (int, const char *);

The below patch fixes that.


Thanks,
Corinna

I don't think this is needed.  What goes wrong without it?

It's not about need, it's about correctness.  It collides with the new,
POSIXly correct declaration of psignal in newlib/libc/include/signal.h.

But this could should not show up if psignal is declared.  So it
should not matter if it collides with that declaration.

I had argued against this patch:

http://gcc.gnu.org/ml/gcc-patches/2011-05/msg00439.html

The newlib change broke ALL released versions of gcc, and the above
patch does NOT fix the problem, but merely hides it until the next
time we trip over it.

So regardless of whether the changes to newlib are a good idea or not, I
think the fix to libiberty is still right. Posix says that psignal takes
a const char *, and libiberty's implementation doesn't.  That's just
silly.

I do agree that the newlib code should be tightened up, particularly in
order to support older compilers; but that doesn't mean we shouldn't fix
libiberty as well.

Thanks.  I just have no check in rights to the gcc repository.  I applied
the change to the sourceware CVS repository but for gcc I need a proxy.

What I don't understand is why the newlib change broke older compilers.
The function has been added to newlib and the definitions in newlib are
correct.

If this is refering to the fact that libiberty doesn't grok
automatically if a symbol has been added to newlib, then that's a
problem in libiberty, not in newlib.

Otherwise, if you're building an older compiler, just use an older
newlib as well.

Irrelevent.  I said I'd accept that change *after* the real problem is
fixed.  The real problem hasn't been fixed.

The real problem is that libibery should NOT INCLUDE PSIGNAL AT ALL if
newlib has it.

What *should* have happened, is libiberty should have been fixed
*first*, and newlib waited until a gcc/binutils release cycle
happened, so that at least ONE version of those could build with
newlib.

Please, never apply libiberty patches only to src.  They're likely to
get deleted by the robomerge.  The rule is: gcc only, or both at the
same time.

Re: Libiberty: POSIXify psignal definition

[DJ Delorie]

> What I don't understand is why the newlib change broke older compilers.

Older compilers have the older libiberty.  At the moment, libiberty
cannot be built by *any* released gcc, because you cannot *build* any
released gcc, because it cannot build its target libiberty.

> The function has been added to newlib and the definitions in newlib are

"Correct" is irrelevent.  They don't match libiberty, so the build
breaks.

It's a problem in every released gcc at the moment, so no released gcc
can be built for a newlib target, without hacking the sources.

The only option here is to not release a newlib at all until a fixed
gcc release happens, then, and require that fixed gcc for that version
of newlib forward.

And the problem is that libiberty is assuming that it *knows* what
functions newlib provides, so that it doesn't need to check directly.
This is just broken...

  # newlib provide and which ones we will be expected to provide.

Historically, cygwin was built using libiberty and newlib, so you did
not have a runtime at the time you were building libiberty, because
you hadn't built newlib yet.

In a combined tree, target-libiberty is still built before
target-newlib, so the problem exists there too.

At this point, though, I'm tempted to say "there's no such thing as a
target libiberty" and rip all the target-libiberty rules out, and let
newlib-hosted targets autodetect the host-libiberty.  That is, if
Cygwin doesn't need a target-libiberty any more?

Cygwin doesn't need libiberty anymore since 2007.

What about these?

dependencies = { module=all-target-libobjc; on=all-target-libiberty; };
dependencies = { module=all-target-libstdc++-v3; on=all-target-libiberty; };

Bogus.  fastjar is not a target module, not should it be one; all 
references to target fastjar should be removed.

> dependencies = { module=all-target-libobjc; on=all-target-libiberty; };

Bogus.  libobjc makes no use of libiberty.

> dependencies = { module=all-target-libstdc++-v3; on=all-target-libiberty; };

Bogus.  libstdc++ uses cp-demangle.c from the libiberty source directory 
via special makefile rules; it makes no other use of libiberty and does 
not use a target libiberty.a, only that source file.

I thought you had the ball on this, but I don't see anything
happened since the above was written.  I could just add clauses
for my own targets, but I want this to happen, so I'll pick it
up if it's on the floor.

It seems none in approval capacity have any objection to
(figuratively) s/target-libiberty//g in toplevel/configure.ac on
all branches.  Is an --enable-target-libiberty or
--with-target-libiberty needed?  (I'd just rather not.)

What would be an approvable test procedure?
Is it enough to test it on native x86_64-linux and cris-axis-elf
(a newlib target) with old and new/breaking newlib?

At a glance this would partially fix PR47836, and completely fix
PR23656, PR47733, PR49247.

There should be no such option.  It should just be a matter of removing 
"target_modules = { module= libiberty; };" and everything that references 
target-libiberty.

Here we go, pretty straightforward.  For lack of other
suggestions, tested as I suggested: native
x86_64-unknown-linux-gnu, cross to cris-axis-elf, both with old
and new ("breaking") newlib.  Note that I didn't (have to)
change libiberty; after this patch there'll be dead code for
target-libiberty ripe for cleanup.  There's a rationale in
<http://gcc.gnu.org/ml/gcc-patches/2011-05/msg01311.html> for
where Joseph mentions some of the bogus dependencies; Looking at
winsup ISTM it's the same (not a *target* dependency, but a
*host* dependency; like a cross-compiler it's built using host
tools and libraries, not using the newly built target tools and
libraries).

Ok for trunk?  Patch for branches will look slightly different;
the code in configure.ac was a single chunk thanks to Joseph
breaking it out earlier.  (Pre-approvals welcome. :)

> Ok for trunk?

Ok with me.  I'll let the branch maintainers decide if they want it
for their branches.

JFTR, that's not proper PR annotation.  I changed it as obvious
to the following, which ends up as intended in bugzilla.

	PR regression/47836
	PR bootstrap/23656
	PR other/47733
	PR bootstrap/49247
	* configure.ac (target_libraries): Remove target-libiberty.
