If you've introduced a new structure - then 55 * it will need to be described - this is done by: 56 * 57 * o adding a new type ELF_T_* to usr/src/head/libelf.h 58 * o Create a new macro to define the bytes contained in the structure. Take a 59 * look at the 'Syminfo_1' macro defined below. The declarations describe 60 * the structure based off of the field size of each element of the structure. 61 * o Add a entry to the fmsize table for the new ELF_T_* type. 62 * o Create a <newtype>_11_tof macro. Take a look at 'syminfo_11_tof'. 63 * o Create a <newtype>_11_tom macro. Take a look at 'syminfo_11_tom'. 64 * o The <newtype>_11_tof & <newtype>_11_tom results in conversion routines 65 * <newtype>_2L11_tof, <newtype>_2L11_tom, <newtype>_2M11_tof, 66 * <newtype>_2M11_tom being created in xlate.c. These routines 67 * need to be added to the 'x32[]' array. 68 * o Add entries to getdata.c::align32[] and getdata.c::align64[]. These 69 * tables define what the alignment requirements for a data type are. 70 * 71 * In order to tie a section header type (SHT_*) to a data 72 * structure you need to update elf32_mtype() so that it can 73 * make the association. If you are introducing a new section built 74 * on a basic datatype (SHT_INIT_ARRAY) then this is all the updating 75 * that needs to be done. 76 * 77 * 78 * ELF translation routines 79 * These routines make a subtle implicit assumption. 80 * The file representations of all structures are "packed," 81 * meaning no implicit padding bytes occur. This might not 82 * be the case for the memory representations. Consequently, 83 * the memory representations ALWAYS contain at least as many 84 * bytes as the file representations. Otherwise, the memory 85 * structures would lose information, meaning they're not 86 * implemented properly. 87 * 88 * The words above apply to structures with the same members. 89 * If a future version changes the number of members, the 90 * relative structure sizes for different version must be 91 * tested with the compiler. 92 */ 93 94#define HI32 0x80000000UL 95#define LO31 0x7fffffffUL 96 97/* 98 * These macros create indexes for accessing the bytes of 99 * words and halfwords for ELFCLASS32 data representations 100 * (currently ELFDATA2LSB and ELFDATA2MSB).
