public static interface JitPassage.Branch

A branch in the p-code

Method Summary

Modifier and Type	Method	Description
default String	describeTo()	Get a string description of the branch target
PcodeOp	from()	The op performing the branch
default boolean	isFall()	Indicates whether this branch represents a fall-through case.

Method Details

from

PcodeOp from()

The op performing the branch

Returns:

the "from" op

isFall

default boolean isFall()

Indicates whether this branch represents a fall-through case.

Note that the from() may not be an actual branching p-code op when isFall is true. A "fall-through" branch happens in two cases. First, and most obvious, is to describe the fall-through case of a conditional branch. Second is when for a p-code op the immediately precedes the target of some other branch. That branch causes a split in basic blocks, and so to encode the fall through from that op into the basic block immediately after, a fall-through branch is added.

Returns:

true if this branch is the fall-through case.

describeTo

default String describeTo()

Get a string description of the branch target

Returns:

the description
