IN_GROUP is non-zero if this is part of a group of changes that must be

function `apply_change_group' will validate and apply the changes.

This is either a register reference, a memory reference,

Register and memory references must have mode MODE in order to be valid,

The information about the insn's operands, constraints, operand modes
etc. is obtained from the global variables set up by extract_insn.
Initial revision From-SVN: r76
1991-11-27 15:45:36 +01:00
WHICH_ALTERNATIVE is set to a number which indicates which
alternative of constraints was matched: 0 for the first alternative,
1 for the next, etc.
In addition, when two operands are match
and it happens that the output operand is (reg) while the
input operand is --(reg) or ++(reg) (a pre-inc or pre-dec),
make the output operand look like the input.
This is because the output operand is the one the template will print.
This is used in final, just before printing the assembler code and by
the routines that determine an insn's attribute.
If STRICT is a positive non-zero value, it means that we have been
called after reload has been completed. In that case, we must
do all checks strictly. If it is zero, it means that we have been called
before reload has completed. In that case, we first try to see if we can
find an alternative that matches strictly. If not, we try again, this
time assuming that reload will fix up the insn. This provides a "best
guess" for the alternative and is used to compute attributes of insns prior
to reload. A negative value of STRICT is used for this internal call. */
