--- Comment #7 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
The test case (g++.dg/tree-ssa/pr107876.C) fails on aarch64-darwin.
FAIL: g++.dg/tree-ssa/pr107876.C -std=gnu++14 scan-tree-dump unswitch
"unswitching loop 1 on .switch. with condition: i_[0-9]+\\(D\\) == 2"
FAIL: g++.dg/tree-ssa/pr107876.C -std=gnu++17 scan-tree-dump unswitch
"unswitching loop 1 on .switch. with condition: i_[0-9]+\\(D\\) == 2"
FAIL: g++.dg/tree-ssa/pr107876.C -std=gnu++20 scan-tree-dump unswitch
"unswitching loop 1 on .switch. with condition: i_[0-9]+\\(D\\) == 2"
The output says:
;; Function test17 (_Z6test17i, funcdef_no=0, decl_uid=4194, cgraph_uid=1,
symbol_order=0)
Estimating # of iterations of loop 1
g++.dg/tree-ssa/pr107876.C:21:7: optimized: unswitching loop 1 on 'if' with
condition: i_7(D) == 0
g++.dg/tree-ssa/pr107876.C:21:7: note: optimized sizes estimated to 0 (true)
and 0 (false) from original size 16
