- recognize insns that set the condition code as a byproduct of other activity
- as well as those that explicitly set `(cc0)'.
-
- This macro is not used on machines that do not use `cc0'.
-
- If there are insns that do not set the condition code but do alter other
- machine registers, this macro must check to see whether they invalidate the
- expressions that the condition code is recorded as reflecting. For example,
- on the 68000, insns that store in address registers do not set the condition
- code, which means that usually `NOTICE_UPDATE_CC' can leave `cc_status'
- unaltered for such insns. But suppose that the previous insn set the
- condition code based on location `a4@(102)' and the current insn stores a
- new value in `a4'. Although the condition code is not changed by this, it
- will no longer be true that it reflects the contents of `a4@(102)'.
- Therefore, `NOTICE_UPDATE_CC' must alter `cc_status' in this case to say
- that nothing is known about the condition code value.
-
- The definition of `NOTICE_UPDATE_CC' must be prepared to deal with the
- results of peephole optimization: insns whose patterns are `parallel' RTXs
- containing various `reg', `mem' or constants which are just the operands.
- The RTL structure of these insns is not sufficient to indicate what the
- insns actually do. What `NOTICE_UPDATE_CC' should do when it sees one is
- just to run `CC_STATUS_INIT'.
-
- A possible definition of `NOTICE_UPDATE_CC' is to call a function that looks
- at an attribute named, for example, `cc'. This
- avoids having detailed information about patterns in two places, the `md'
- file and in `NOTICE_UPDATE_CC'. */
