public class SSAOptions
This module defines parameters to the SSA construction process. This is used to pass information between compiler phases.
IMPORTANT: Phases that change the SSA state MUST update the SSA actual options held by the IR object.
| Field Summary | |
|---|---|
private boolean |
abort
abort all ssa passes? |
private boolean |
backwards
construct Heap SSA for backwards analysis? |
private boolean |
excludeGuards
ignore guards (validation regs) ? |
private Set<Object> |
heapTypes
restrict Heap SSA to this set of types? |
private boolean |
heapValid
is Heap SSA info valid? |
private boolean |
insertPEIDeps
constuct Heap SSA with PEI deps? |
private boolean |
insertUsePhis
constuct Heap SSA with uPhi functions? |
private boolean |
scalarsOnly
construct SSA only for scalars? |
private boolean |
scalarValid
is Scalar SSA info valid? |
| Constructor Summary | |
|---|---|
SSAOptions()
default configuration: just perform forward scalar SSA |
|
SSAOptions(boolean scalarsOnly,
boolean backwards,
boolean insertUsePhis,
Set<Object> heapTypes)
Set up instructions for an form of heap Array SSA, or turn it off |
