A relocation defintion has the following information: +// +// Name: This is the name of the relocation without the "R_ARM_" prefix. +// +// Type: Relocation type. There are four. +// - STATIC for static relocations processed by a static linker. +// - DYNAMIC for dynamic relocations processed by a dynamic linker. +// - PRIVATE for R_ARM_PRIVATE_<n> private relocation type. +// - OBSOLETE for old relocation types no longer used. +// We do not use DEPRECATED as a distinct type since we still have to +// handle deprecated relocations so we one of the types above. +// +// Deprecated: Whether this is a deprecated relocation type. The linker +// is expected to handle these though they should not be generated by fully +// conforming tool-chains. +// +// Operation: An expression specifying how the linker should performace a +// relocation. If there is no operation or the operation cannot be +// specified, it is "NONE". +// +// Implemented: Whether this is implemented by the gold. +// +// Group_index: For a group relocation type, it is one of 0, 1 or 2. For +// a non-group relocation type, it is -1. +// +// Overflow: Whether gold should check for overflow.
