3199/* These two relocations are used by the linker to determine which of
3200the entries in a C++ virtual function table are actually used. When
3201the --gc-sections option is given, the linker will zero out the entries
3202that are not used, so that the code for those functions need not be

3204
3205VTABLE_INHERIT is a zero-space relocation used to describe to the
3206linker the inheritence tree of a C++ virtual function table. The
3207relocation's symbol should be the parent class' vtable, and the
3208relocation should be located at the child vtable.
3209
3210VTABLE_ENTRY is a zero-space relocation that describes the use of a
3211virtual function table entry. The reloc's symbol should refer to the
3212table of the class mentioned in the code. Off of that base, an offset
3213describes the entry that is being used. For Rela hosts, this offset
3214is stored in the reloc's addend. For Rel hosts, we are forced to put
3215this offset in the reloc's section offset. */
