|
|
|
//
|
|
|
|
|
// 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.
