| 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 | |
| 9b547ce6 | 27 | // table below. A relocation definition has the following information: |
| 0d31c79d DK |
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 | // | |
| 9b547ce6 | 43 | // Operation: An expression specifying how the linker should perform a |
| 0d31c79d DK |
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. | |
