java.lang.Object
org.jikesrvm.compilers.baseline.PendingRETInfo
final class PendingRETInfo
- extends Object
This class is used during the processing of reference maps for a method.
When a JSR has been processed the processing of a RET is pending.
Need to track which JSR was processed, and where the "return address" value
is being held (i.e. is it on the operand stack, or in a local variable).
The value starts on the top of the stack, but is usually quickly moved to
a local variable.
