tree-optimization/107107 - tail-merging VN wrong-code
The following fixes an unintended(?) side-effect of the special
MODIFY_EXPR expression entries we add for tail-merging during VN.
We shouldn't value-number the virtual operand differently here.
PR tree-optimization/107107
* tree-ssa-sccvn.cc (visit_reference_op_store): Do not
affect value-numbering when doing the tail merging
MODIFY_EXPR lookup.
* gcc.dg/pr107107.c: New testcase.
