-/* There is a set of targets whose general-purpose move or addition
- instructions clobber the flags. These targets cannot split their
- CBRANCH/CSTORE etc patterns before reload is complete, lest reload
- itself insert these instructions in between the flags setter and user.
- Because these targets cannot split the compare from the use, they
- cannot make use of the comparison elimination offered by the combine pass.
-
- This is a small pass intended to provide comparison elimination similar to
- what was available via NOTICE_UPDATE_CC for cc0 targets.
-
- This pass assumes:
-
- (0) CBRANCH/CSTORE etc have been split in pass_split_after_reload.
-
- (1) All comparison patterns are represented as
-
- [(set (reg:CC) (compare:CC (reg) (reg_or_immediate)))]
-
- (2) All insn patterns that modify the flags are represented as
-
- [(set (reg) (operation)
- (clobber (reg:CC))]
-
- (3) If an insn of form (2) can usefully set the flags, there is
- another pattern of the form
-
- [(set (reg:CCM) (compare:CCM (operation) (immediate)))
- (set (reg) (operation)]
-
- The mode CCM will be chosen as if by SELECT_CC_MODE.
-
- Note that unlike NOTICE_UPDATE_CC, we do not handle memory operands.
- This could be handled as a future enhancement.
