| 1068 | Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r. |
| 1069 | Create ELF header in output file. Change mode of output file according to |
| 1070 | output file type. Reorganize callback initialization in ld. |
| 1071 | |
| 1072 | Version 0.20: |
| 1073 | |
| 1074 | Fix some memory leaks in libelf. |
| 1075 | |
| 1076 | Version 0.19: |
| 1077 | |
| 1078 | Implement reading version script. Both inside linker scripts and via the |
| 1079 | --version-script command line parameter. Uses the same code. |
| 1080 | What remains to be done is to implement a data structure which allows |
| 1081 | efficient matching against the version names to decide which pattern |
| 1082 | matches. |
| 1083 | |
| 1084 | Beginning of output generation and output writing functions. |
| 1085 | |
| 1086 | Version 0.18: |
| 1087 | |

| 1089 | and LD_LIBRARY_PATH handling. |
| 1090 | |
| 1091 | Version 0.17: |
| 1092 | |
| 1093 | make handling of e_shnum overflow in libelf standard conforming |
| 1094 | |
| 1095 | ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH, |
| 1096 | DT_RPATH, -rpath, -rpath-link still remains to be implemented. |
| 1097 | |
| 1098 | fix handling of -L parameters. Make actual use of the default_paths element. |
| 1099 | |
| 1100 | make re-definition of symbols in and from DSO compatible with existing linker |
| 1101 | |
| 1102 | Version 0.16: |
| 1103 | |
| 1104 | more work on assigning input sections to output sections. |
| 1105 | |
| 1106 | Add gelf_xlatetof and gelf_xlatetom which were accidently left out. |
| 1107 | |
| 1108 | Fix memory handling of section headers. |
| 1109 | |
| 1110 | Version 0.15: |
| 1111 | |
| 1112 | Add many-section support to ld. Add various new command line parameters. |
| 1113 | Allow pagesize to be specified in linker script or on the command line. |
| 1114 | Collect input sections in list for the output section according to the rules |
| 1115 | specified in the linker script. |
| 1116 | |
| 1117 | Version 0.14: |
| 1118 | |
| 1119 | Fix some problems in the internal list handling which had the result |
| 1120 | that we didn't look for some of the unresolved symbols. |
| 1121 | |
| 1122 | Free some memory if we know we don't need it anymore. |
| 1123 | |
| 1124 | Optimize the list of unresolved symbols. Throw out symbols which are |
| 1125 | meanwhile resolved. |
| 1126 | |
| 1127 | Version 0.13: |
| 1128 | |
| 1129 | Got file reading correct now. The files are all read while parsing |
| 1130 | the parameters. No creating of data structures to describe the linker |
| 1131 | command line. The symbol table is built up while reading the files. |
| 1132 | DSOs are handled now. -( -) handling is optimized. |
| 1133 | |
| 1134 | Version 0.12: |
| 1135 | |
| 1136 | Linker read linker scripts everywhere. Handles --whole-archive. Recognizes |
| 1137 | --dynamic and --static. Collects defined and undefined symbols. Recognizes |
| 1138 | conflicts. |
| 1139 | |
| 1140 | libebl now defines functions to call the callbacks. Add generic name handling |
| 1141 | in these new functions. Remove the code from readelf and call the new |
| 1142 | functions. |
| 1143 | |
| 1144 | Version 0.11: |
| 1145 | |
| 1146 | Start of linker. Basic argument parsing, finding of input files, |
| 1147 | linker script reading. |
