Detailed Description

An entry in a MachineConstantPool.

This class is a data container for one entry in a MachineConstantPool. It contains a pointer to the value and an offset from the start of the constant pool.

unsigned MachineConstantPoolEntry::getRelocationInfo ( ) const

getRelocationInfo - This method classifies the entry according to whether or not it may generate a relocation entry. This must be conservative, so if it might codegen to a relocatable entry, it should say so. The return values are:

0: This constant pool entry is guaranteed to never have a relocation applied to it (because it holds a simple constant like '4'). 1: This entry has relocations, but the entries are guaranteed to be resolvable by the static linker, so the dynamic linker will never see them. 2: This entry may have arbitrary relocations.
