Garbage collection metadata for a single function. Currently, this information only applies to GCStrategies which use GCRoot.
Declared in <llvm/CodeGen/GCMetadata.h>
class GCFunctionInfo;| Name | Description |
|---|---|
iterator | Iterator over safe points in this function. |
live_iterator | Const iterator over roots treated as live at a safe point. |
roots_iterator | Iterator over all GC roots in this function. |
| Name | Description |
|---|---|
GCFunctionInfo [constructor] | Construct GC metadata for function F using strategy S. |
~GCFunctionInfo [destructor] | Destroy this function's GC metadata. |
addSafePoint | addSafePoint - Notes the existence of a safe point. Num is the ID of the label just prior to the safe point (if the code generator is using MachineModuleInfo). |
addStackRoot | Register a root that lives on the stack. |
begin | begin/end - Iterators for safe points. |
end | Return an iterator past the last safe point. |
getFrameSize | getFrameSize/setFrameSize - Records the function's frame size. |
getFunction | getFunction - Return the function to which this metadata applies. |
getStrategy | getStrategy - Return the GC strategy for the function. |
invalidate | Handle invalidation explicitly. |
live_begin | live_begin/live_end - Iterators for live roots at a given safe point. |
live_end | Return an iterator past the last live root at safe point p. |
live_size | Return the number of live roots at safe point p. |
removeStackRoot | removeStackRoot - Removes a root. |
roots_begin | roots_begin/roots_end - Iterators for all roots in the function. |
roots_end | Return an iterator past the last root in the function. |
roots_size | Return the number of roots in the function. |
setFrameSize | Record the function's frame size in bytes. |
size | Return the number of safe points in this function. |
