+       PR rtl-optimization/15521:
+       * sched-int.h (in_post_call_group_p): Change type to enum.
+       * sched-deps.c (sched_analyze_insn):
+       (sched_analyze): When in_post_call_group_p is post_call_initial,
+       don't add a dependency, but still set SCHED_GROUP_P and CANT_MOVE,
+       and also reset in_post_call_group_p to post_call.
+       (sched_analyze): When the previous basic block ended in a CALL_INSN,
+       initialize in_post_call_group_p as post_call_initial.
+       (init_deps): initialize in_post_call_group_p to not_post_call.
