// The information here is based on the official ARM document "ELF for ARM
|
|
// Architecture" (Document number ARM IHI 0044C). The first five columns of
|
|
// the table below are derived from Table 4-8 in the ARM ELF document. Each
|
|
// relocation from Table 4-8 corresponds to one relocation definition in the
|
|
// table below. 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. This is "No" by default
|
|
// for relocation types DYNAMIC, PRIVATE and OBSOLETE.
