/* 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 is available via NOTICE_UPDATE_CC for cc0 targets. This should help
|
||
encourage cc0 targets to convert to an explicit post-reload representation
|
||
of the flags.
|
||
|
||
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) (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) (operation)
|
||
(set (reg:CCM) (compare:CCM (operation) (immediate)))]
|
||
|
||
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.
