You can still reproduce the issue on the trunk with "-O1 -fdisable-tree-cselim
-fno-tree-sink" .
RTL ifcvt does:
starting the processing of deferred insns
ending the processing of deferred insns
df_analyze called
df_worklist_dataflow_doublequeue: n_basic_blocks 6 n_edges 6 count 6 ( 1)
IF-THEN-ELSE-JOIN block found, pass 1, test 2, then 3, else 4, join 5
changing bb of uid 15
from 4 to 2
deleting insn with uid = 16.
deleting block 4
Removing jump 6.
deleting insn with uid = 6.
deleting insn with uid = 9.
deleting insn with uid = 8.
deleting block 3
Merging block 5 into block 2...
changing bb of uid 22
Merged blocks 2 and 5.
Conversion succeeded on pass 1.
