--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, the problem seems to be aggressive scheduling of the
(insn/f 72 71 73 7 (set (reg:SI 0 0)
(reg:SI 65 lr)) "pr83986.c":5 483 {*movsi_internal1}
(expr_list:REG_DEAD (reg:SI 65 lr)
(nil)))
frame related instruction across a branch, from the basic block containing the
shrink-wrapped prologue to the predecessor, which only conditionally branches
to the prologue.
Shall we disallow moving of frame related instructions across branches in the
scheduler?
