This macro is not used on machines that do not use `cc0'. */
/* #define CC_STATUS_MDEP_INIT */
/* A C compound statement to set the components of `cc_status' appropriately
for an insn INSN whose body is EXP. It is this macro's responsibility to
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'. */
