commit 69ce0f4dc79a5606eec03accd81832aaeaa16075 Author: rmcilroy <[email protected]> Date: Thu Aug 27 11:11:09 2015 [interpreter] Add constant_pool() to BytecodeArray. Adds a (currently unused) constant_pool() field to BytecodeArray objects.This field points to a FixedArray object which will be used to hold constants.
The BytecodeArray is now a mixed values object type, with thekConstantPoolOffset object holding a tagged pointer, but the remainder of the object holding raw bytes (which could look like tagged pointers but are not).
Modify the BytecodeArray GC visitors to deal with this and test that the field is migrated properly when evacuated.
