23 // The information here is based on the official ARM document "ELF for ARM
24 // Architecture" (Document number ARM IHI 0044C). The first five columns of
25 // the table below are derived from Table 4-8 in the ARM ELF document. Each
26 // relocation from Table 4-8 corresponds to one relocation definition in the
27 // table below. A relocation definition has the following information:
28 //
29 // Name: This is the name of the relocation without the "R_ARM_" prefix.
30 //
31 // Type: Relocation type. There are four.
32 // - STATIC for static relocations processed by a static linker.
33 // - DYNAMIC for dynamic relocations processed by a dynamic linker.
34 // - PRIVATE for R_ARM_PRIVATE_<n> private relocation type.
35 // - OBSOLETE for old relocation types no longer used.
36 // We do not use DEPRECATED as a distinct type since we still have to
37 // handle deprecated relocations so we one of the types above.
38 //
39 // Deprecated: Whether this is a deprecated relocation type. The linker
40 // is expected to handle these though they should not be generated by fully
41 // conforming tool-chains.
42 //
43 // Operation: An expression specifying how the linker should perform a
44 // relocation. If there is no operation or the operation cannot be
45 // specified, it is "NONE".
46 //
47 // Implemented: Whether this is implemented by the gold.
48 //
49 // Group_index: For a group relocation type, it is one of 0, 1 or 2. For
50 // a non-group relocation type, it is -1.
51 //
52 // Overflow: Whether gold should check for overflow. This is "No" by default
53 // for relocation types DYNAMIC, PRIVATE and OBSOLETE.
