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. 54 // 55 // Overflow-----------------------------------------------------------------+ 56 // Group index----------------------------------------------------------+ | 57 // Implemented-------------------------------------------------------+ | | 58 // Operation-------------------------------+ | | | 59 // Class----------------------------+ | | | | 60 // Deprecated--------------------+ | | | | | 61 // Type----------------+ | | | | | | 62 // Name | | | | | | | 63 // | | | | | | | | 64 RD(NONE , STATIC , N, MISC , NONE , Y, -1, N) 65 RD(PC24 , STATIC , Y, ARM , ((S + A) | T) -
