implemented in code to refer to each global variable indirectly through got, so that the simple data references in the code become complex and must be added to the instructions that got the appropriate contents of the table. The reference to read-only data is also based on the same principle, so adding the code compiled by the IC is much more expensive than the usual code. If an elf executable needs to invoke any function defined in a shared library, then it has its own got and PLT (Procedure
