--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For comment #1 in GCC 8+, the problem shows up in thread1:
;; Invalid sum of incoming counts 332256647 (estimated locally), should be
365072220 (estimated locally)
On the trunk in thread1:
;; basic block 6, loop depth 0, count 0 (precise), probably never executed
;; Invalid sum of incoming counts 20359759 (estimated locally), should be 0
(precise)
;; prev block 5, next block 7, flags: (NEW, VISITED)
;; pred: 4 [never] count:0 (precise) (TRUE_VALUE,EXECUTABLE)
;; 5 [11.4% (guessed)] count:20359759 (estimated locally)
(TRUE_VALUE,EXECUTABLE)
# .MEM_16 = PHI <.MEM_11(4), .MEM_12(5)>
# .MEM_8 = VDEF <.MEM_16>
# USE = nonlocal

abortD.1081 ();
;; succ:

hot
