-Subject: [PATCH] PTA: Fix wrong optimization of conditional dynamic allocation
-
-This is a regression present on mainline, 16, 15 and 14 branches introduced
-by the fix for PR tree-optimization/112653 (PTA and return).  What happens
-is that DSE incorrectly eliminates a call to memcpy, whose destination is
-obtained from (an equivalent of) malloc and is ultimately returned from the
-function.  But this happens only when the dynamic allocation is conditional.
-
-The difference between the unconditional and conditional cases is:
-
-ESCAPED_RETURN = { ESCAPED NONLOCAL HEAP(30) }
-
-vs
-
-ESCAPED_RETURN = { ANYTHING }
-
-The fix is to apply in set_uids_in_ptset the same treatment to ANYTHING in
-the escaped return case as in the escaped case.
-
-gcc/
-	* tree-ssa-structalias.cc (set_uids_in_ptset): If ANYTHING is
-	present in the ESCAPED_RETURN solution, record that the global
-	solution has an escaped heap if FROM contains a heap variable.
-
-gcc/testsuite/
-	* gnat.dg/opt109.adb: New test.
-	* gnat.dg/opt109_pkg.ads, gnat.dg/opt109_pkg.adb: New helper.
