gcc-4.3.0 revision 129794

Builds fine with gcc 4.1.2 as boostrap compiler:
Target: hppa2.0w-hp-hpux11.00
Configured with:
/raid/tecosim/it/devel/projects/develtools/src/gcc-4.3.0/configure

What I mean is that 4.2's rtl has the same issue. What happens if you try to
bootstrap 4.2 with 4.3?

I can't produce the bug on x86_64-linux-gnu, but could you give the
attached patch a go?  Thanks.

------- Comment #12 from rsandifo at gcc dot gnu dot org  2007-11-08 16:10 -------
Interesting.  Something platform-specific must be going wrong here.
The original build failure shouldn't have happened even without
the attached patch because ggc-none.o should provide a definition
of ggc_free.  The cc1 link shouldn't fail because $(GGC).o should
be linked into libbackend.a.

It's probably easier to track down why the original failure happened,
rather than why the cc1 one happened, so could you try again without
the patch I attached and see why ggc-none.o isn't providing a
definition of ggc_free?

As things stand, I don't think this was caused by my 2006 patch
after all, so I'll unassign myself to avoid confusion.  (I'll keep
myself on cc: because I'm curious what's wrong.)

But according to PR32636, gcc can bootstrap on hppa2.0w-hp-hpux11.11.
Perhaps you have a buggy linker?  nm dump you posted shows definition of those
symbols...

I'm completly lost. On the same machine:
Actual 4.2 branch works fine. Bootstrapping without java and using the
resulting gcc as bootstrap compiler for both configurations
hppa2.0w-hp-hpux11.00 and hppa64-hp-hpux11.00 is working.
The same is true for trunk and hppa64-hp-hpux11.00.
Bootstrapping trunk for hppa2.0w-hp-hpux11.00 is fine too.
The problem only arises if I use trunk for bootstrapping trunk.

Here the complete linker step. I added the -v -t +vallcompatwarnings command
line switches.

Ok, got it, minimal testcase is:
extern void foo (void);
int bar (void) { foo (); return 1; }
extern void foo (void);
with -fno-unit-at-a-time there is no .IMPORT directive for foo (removing the
prototype after use fixes this).

Lack of a .IMPORT for ggc_free will cause link errors.  The linker
default is "DATA".

------- Comment #27 from jakub at gcc dot gnu dot org  2007-12-13 17:34 -------
First of all I wonder what's the point of the PA ASM_OUTPUT_EXTERNAL_REAL vs.
ASM_OUTPUT_EXTERNAL hacks.  The middle-end already does the deferring itself,
see
assemble_external/process_pending_assemble_externals/assemble_external_real.
The only place where ASM_OUTPUT_EXTERNAL is invoked is during
process_pending_assemble_externals, i.e. right before targetm.asm_out.file_end
(well, there is also output of IDENT_ASM_OP, but that isn't relevant).
So, PA buffers the externals once again, from the
process_pending_assemble_externals call to the immediately following
file_end.

Indeed, removing that second deferral cures this.

I think I deferred the PA output before the middle-end deferral was
implemented.

------- Comment #30 from jakub at gcc dot gnu dot org  2007-12-13 18:58 -------
If PA wants to keep the guards (!TREE_ASM_WRITTEN && SYMBOL_REF_REFERENCED_P
()),
it can, but that surely can be done in ASM_OUTPUT_EXTERNAL too, doesn't need
any deferral.  In that case this will be broken again.  From what I see this is
caused by 
http://gcc.gnu.org/ml/gcc-patches/2005-06/msg02029.html
which removed copying of DECL_RTL from olddecl to newdecl (but kept the
DECL_RTL_SET_P hunk at the end, which now never triggers).  Because of that
change DECL_RTL after duplicate_decls is now created from scratch and so the
PA specific bit whether it was referenced or not is not set.
I guess we should fix merge_decls no matter what PA chooses.

At this point in time, I can't remember whether this is essential or
not.  I believe this was done to avoid duplicated and unnecessary directives.
I'm fairly sure a .IMPORT directive for a symbol that isn't referenced doesn't
cause problems.

I'll try your change tonight.

I have a patch to fix c-decl.c and pa_encode_section_info which together fixes
this bug.  I'll prepare a testcase and submit.  The removal of the unnecessary
deferral can be postponed for later.
