For example, in the pattern thumb_subdi3 +;; below, the output SUB implicitly sets the flags (assembled to SUBS) +;; and then the Carry flag is used by SBC to compute the correct +;; result. If we split thumb_subdi3 pattern into two separate RTL +;; insns (using define_insn_and_split), the scheduler might place +;; other RTL insns between SUB and SBC, possibly modifying the Carry +;; flag used by SBC. This might happen because most Thumb1 patterns +;; for flag-setting instructions do not have explicit RTL for setting +;; or clobbering the flags. Instead, they have the attribute "conds" +;; with value "set" or "clob". However, this attribute is not used to +;; identify dependencies and therefore the scheduler might reorder +;; these instruction. Currenly, this problem cannot happen because +;; there are no separate Thumb1 patterns for individual instruction +;; that consume flags (except conditional execution, which is treated +;; differently).
