- Subject: [tree-ssa]: Overlap of variable with same variable?
When I hit the abort, it says there is an overlap between t and var
Except that:
(gdb) p debug_generic_expr (t)
pretmp.389_37
$1 = void
(gdb) p debug_generic_expr (var)
pretmp.389
This is not a possible overlap, they are the same variable.
If it helps, it could be we aren't updating the end of the bb tree
properly either , since in this case, pretmp.389_37 is saved only to a
statement at the end of a bb, and thus, if end_bb wasn't updated
properly, the out-of-ssa dropper would miss it.
Any ideas?
