[Bug tree-optimization/31847] [4.3 Regression] Printing to dump file broken

[simartin at gcc dot gnu dot org]

Hello.

I've had a look at the code, and the PRE dump apparently directly calls
print_generic_expr (not via default_tree_printer) with TDF_DIAGNOSTIC in the
dump flags. I'm not sure how those flags are setup...

I think there is a problem in tree-dump.c (TDF_DIAGNOSTIC will be erroneously
passed in some dump flags), fixed by this patch:

Index: tree-dump.c
===================================================================
--- tree-dump.c (revision 124477)
+++ tree-dump.c (working copy)
@@ -803,7 +803,7 @@
   {"stmtaddr", TDF_STMTADDR},
   {"memsyms", TDF_MEMSYMS},
   {"all", ~(TDF_RAW | TDF_SLIM | TDF_LINENO | TDF_TREE | TDF_RTL | TDF_IPA 
-           | TDF_STMTADDR | TDF_GRAPH)},
+           | TDF_STMTADDR | TDF_GRAPH | TDF_DIAGNOSTIC)},
   {NULL, 0}
 };


However, I'm not sure this will fix this issue, and I have not been able to
test it. Would you mind trying it? Thanks.

I'll look more closely on this issue this evening when I'm back from work.

Sorry for this breakage.
Simon
