gcc.dg/pr50132.c is caused by shrink wrap:

--- Comment #2 from Richard Henderson <rth at gcc dot gnu.org> 2011-10-06 19:04:34 UTC ---
The problem is that the CSA pass is dropping a note when combining
(insn 13 12 16 3 (parallel [
(set (reg/f:DI 7 sp)
(plus:DI (reg/f:DI 7 sp)
(const_int 16 [0x10])))
(clobber (reg:CC 17 flags))
]) z.c:9 254 {*adddi_1}
(expr_list:REG_ARGS_SIZE (const_int 0 [0])
(nil)))
(insn/f 31 30 35 4 (parallel [
(set (reg/f:DI 7 sp)
(plus:DI (reg/f:DI 7 sp)
(const_int 8 [0x8])))
(clobber (reg:CC 17 flags))
(clobber (mem:BLK (scratch) [0 A8]))
]) z.c:10 -1
(expr_list:REG_CFA_ADJUST_CFA (set (reg/f:DI 7 sp)
(plus:DI (reg/f:DI 7 sp)
(const_int 8 [0x8])))
(nil)))
to
(insn/f 31 30 35 3 (parallel [
(set (reg/f:DI 7 sp)
(plus:DI (reg/f:DI 7 sp)
(const_int 24 [0x18])))
(clobber (reg:CC 17 flags))
(clobber (mem:BLK (scratch) [0 A8]))
]) z.c:10 921 {pro_epilogue_adjust_stack_di_add}
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_CFA_ADJUST_CFA (set (reg/f:DI 7 sp)
(plus:DI (reg/f:DI 7 sp)
(const_int 8 [0x8])))
(nil))))
We've lost the REG_ARGS_SIZE note, which also affects the CFA
given that we're not using a frame pointer.
