The variable can not actually be used uninitalized, since min_cost is
initalized to INT_MAX, and the return type of rtx_cost is int.
So it is enough to shut up the compiler warning, no need to add an
extra test there. I.e. the first hunk should be sufficient.

--- Comment #36 from amylaar at gcc dot gnu dot org 2010-07-08 11:04 --- (In reply to comment #35) The ordering issue in VRP needs to be fixed. The sorting can use LABEL_DECL_UID which is dense in a given function. (but watch out for a -1 value where no UID has been assigned) I think that is too late; it would solve this particular failure, but AAUI, once we allow the relative order of decl_uids to become random, we've lost. There is also the wider issue that this entire business of allowing decl_uids to drift as long as ordering is preserved makes impossible to use dump comparisons as an effective means to determine in what pass things go wrong. It appears that in general, we use negative decl_uids for debug symbols, yet we may retain / copy non-debug symbols for reasons of debugging and let them have positive numbers. I wonder if it would be feasible to allocate new negative the uids for such symbols when they only remain for purposes of debugging, and when we somehow end up merging a debug and non-debug copy, the non-debug with its positive decl_uid should prevail. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44832

That would be a bug as well. Indeed we do; once that is fixed, the vrp ordering should be fixed as well. (In reply to comment #37) This is what we have the -nouid modifier for. But this doesn't allow us to use diff to tell if the relative order is OK in one dump while messed up in the other. It hides all the ordering problems, so this option is no good at all to track down the pass where things go wrong.

You have lost me here again. That's a tentative idea how not only the ordering problem could be solved, but also the debug/no-debug variance of decl_uids on declarations / labels that are present in the no-debug output, to allow for meaningful diffs.

When comparing dumps from compilations with debugging information generation enabled and disabled, like for -fcompare-debug, commonly dump files generated with TDF_NOUID are used. However, as has become painfully clear while debugging PR44832, such dumps do not help to spot the point where the DECL_UID ordering of declarations / labels varies. There should be a flag to request an enumeration of all declarations / labels of each function to be dumped in the order of their DECL_UID as part of the debugging dump for the function. Also, a dump of FREE_SSANAMES can be useful at times. -- Summary: TDF_NOUID dumps miss information about DECL_UID ordering Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: other AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amylaar at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44874

We have to preserve used labels in the block tree it's just not trivial to do unless we resort to setting TREE_USED. Which would be the following, which also fixes the failure. I have done a --enable-build-with-cxx bootstrap of trunk trevision 161952 with this patch applied (with tabs for leading whitespace in the comment).

So an option would be to unconditionally preserve all !DECL_INGNORED_P labels in BLOCKs. Which is what my provisional patch was doing, although it'd need better commenting and deletion of dead tests / code. Or play fancy with a bitmap or a pointer-map. Could we use a different bit that is currently unused for LABEL_DECLs? (With a suitable accessor macro, of course.) The name of base.public_flag sounds about right, but might be a bit dangerous considering the unguarded TREE_PUBLIC accessor and possible mix-ups when code is meant to test TREE_PUBLIC of declarations.

(With a suitable accessor macro, of course.) Hmm, actually, there should be no problem with changing TREE_USED of a LABEL_DECL once lang_hooks.parse_file is done with emitting warnings about undefined-but-used / used-but-not-defined labels. The problem is clearing them all at or before the start of remove_unused_locals. It's be easy to do in one frontend, when we do the warnings, but requiring all the frontends to do it is messy, and it when remove_unused_locals is called multiple times that'd not reset the used flag for labels the used of which have been optimized away in the meantime. I think the TREE_USED as given from the frontends is probably a good enough approximation if we also take DECL_IGNORED_P into account. As it happens, TREE_USED is actually cleared by init_vars_expansion, although, as stated before, it should be good enough without that. I'm currently testing the attached patch. Regarding a testcase for our testsuite, I think that would best be done in the context of PR other/44874. Although we should be able to reproducibly get scrabled DECL_UIDs with the old compiler logic, having this translate into different ssa name versioning or even generated code is less reliable when you change bits of the compiler or the compiler host / target. With a dump option to enumerate declarations / labels in DECL_UID order, the regression test can verify that order matches. I think this dump option should be default for -fcompare-debug; in that case, the testcase should be relatively simple. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44832

Successfully bootstrapped ergtested in trunk revision 161952, both with without --enable-build-with-cxx. The only difference in the test results to the baseline was that a timeout for libmudflap.cth/pass40-frag.c went away to change a pair of FAILs to a pair of PASSes; this is one of the test that now and then times out on my machine, depending on load. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44832

[Bug debug/44832] [4.6 Regression] -fcompare-debug failure for C++ i386.c
--- Comment #34 from amylaar at gcc dot gnu dot org 2010-07-08 01:10
---
FWIW, this simple patch stops the comparison failures both for my reduced
testcase as for the original testcase. I'm not sure if we want to
pay the price of carryinig more labels around for -g0, or if we'd rather
fix the ordering issues somehow.

directory with:
../g++ -B.. -da -march=pentiumpro -mtune=generic -m32 t.c --dump-tree-all -g
-S -fdump-unnumbered

Hmm, that's actually the same as for r160828; but still, r160828 passes the
-fcompare-debug debug test with the reduced test case, while r160832 fails it.
Running this test with --save-temps and diffing the output shows that somehow
we end up with different tmp_var_id_num values for variables created by

preprocessed source
Preprocessed source of ia64.i for your convenience.
Thanks, in the meantime, I found out that all these errors are genuine - sort
of. The real smoking gun are 'nested function' warnings. By searching for
the first one, I found a stray '{'. I've committed the fix as obvious.

As I used cut paste for a few repeated stanzas, I just checked if
there was any more of the same.
Once you know what it is, it's easy to find in the patch:
[amyl...@laria ~]$ grep -A 5 -B 5 '^+[ ]*{' 44566-regclass-diff-3
static int
-ia64_register_move_cost (enum machine_mode mode, enum reg_class from,
-enum reg_class to)
+ia64_register_move_cost (enum machine_mode mode, enum reg_class from_i,
+enum reg_class to_i)
+{
+ enum reg_class from = (enum reg_class) from_i;
+ enum reg_class to = (enum reg_class) to_i;
{
/* ADDL_REGS is the same as GR_REGS for movement purposes. */
if (to == ADDL_REGS)
so this typo was specific to ia64.c

--- Comment #4 from amylaar at gcc dot gnu dot org 2010-07-01 19:14 --- Alternatively, we could hookize FLOAT_WORDS_BIG_ENDIAN, and make jcf-parse.c include target.h so it gets access to the target vector. This would also be better since then the code in jfc-parse.c no longer depends on the target. If there are concerns about the performance impact an real.c, we could leave the interface for the targets to define FLOAT_WORDS_BIG_ENDIAN, and let real.c use the macro directly, while requiring that front ends use the target hook defined in targhooks.c . -- amylaar at gcc dot gnu dot org changed: What|Removed |Added CC||amylaar at gcc dot gnu dot ||org OtherBugsDependingO||44566, 44756 nThis|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44335

--- Comment #1 from amylaar at gcc dot gnu dot org 2010-06-29 19:13 --- Sorry, I certainly didn't mean to put a rule there; not sure if it was a typo or some smartass-autoindent running wild.
