Handling of DT_RUNPATH, +DT_RPATH, -rpath, -rpath-link still remains to be implemented. + +fix handling of -L parameters. Make actual use of the default_paths element. + +make re-definition of symbols in and from DSO compatible with existing linker + +Version 0.16: + +more work on assigning input sections to output sections. + +Add gelf_xlatetof and gelf_xlatetom which were accidently left out. + +Fix memory handling of section headers. + +Version 0.15: + +Add many-section support to ld. Add various new command line parameters. +Allow pagesize to be specified in linker script or on the command line. +Collect input sections in list for the output section according to the rules +specified in the linker script. + +Version 0.14: + +Fix some problems in the internal list handling which had the result +that we didn't look for some of the unresolved symbols. + +Free some memory if we know we don't need it anymore. + +Optimize the list of unresolved symbols. Throw out symbols which are +meanwhile resolved. + +Version 0.13: + +Got file reading correct now. The files are all read while parsing +the parameters. No creating of data structures to describe the linker +command line. The symbol table is built up while reading the files. +DSOs are handled now. -( -) handling is optimized. + +Version 0.12: + +Linker read linker scripts everywhere. Handles --whole-archive. Recognizes +--dynamic and --static. Collects defined and undefined symbols. Recognizes +conflicts. + +libebl now defines functions to call the callbacks. Add generic name handling +in these new functions. Remove the code from readelf and call the new +functions. + +Version 0.11: + +Start of linker. Basic argument parsing, finding of input files, +linker script reading. + +Version 0.10: + +Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(), +dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(), +dwarf_get_abbrev_entry(), dwarf_get_fde_at_pc(), and tests for it. + +Version 0.9: + +Implement dwarf_get_fde_list_eh(), dwarf_get_cie_of_fde(), +dwarf_get_fde_range(), dwarf_get_cie_info(), dwarf_get_fde_instr_bytes(), +and tests for them. + +Version 0.8: + +Make handling of binaries in other byte order work and add tests for it. + +Version 0.7: + +Implement dwarf_get_aranges(), dwarf_get_arange(), dwarf_get_cu_die_offset(), +dwarf_get_arange_info(), and tests for them. + +Version 0.6: + +Implement dwarf_get_global(), dwarf_globname(), dwarf_global_die_offset(), +dwarf_global_cu_offset(), dwarf_global_name_offsets(), and tests for them + +Version 0.5: + +Implemented dwarf_srclines(), dwarf_srcfiles(), dwarf_linebeginstatement(), +dwarf_lineendsequence(), dwarf_lineno(), dwarf_lineaddr(), dwarf_lineoff(), +dwarf_linesrc(), dwarf_lineblock(), dwarf_lineprologueend(), +dwarf_lineepiloguebegin(), and tests for them. + +Version 0.4: + +Implemented dwarf_loclist(). + +Version 0.3: + +Implemented dwarf_dieoffset(), dwarf_die_CU_offset(), dwarf_diename() and +tests. + +Implemented dwarf_attrlist(), dwarf_hasattr(), dwarf_attr(), dwarf_lowpc(), +dwarf_highpc(), dwarf_bytesize(), dwarf_bitsize(), dwarf_bitoffset(), +dwarf_srclang(), dwarf_arrayorder(), dwarf_hasform(), dwarf_whatform(), +dwarf_whatattr(), dwarf_formref(), dwarf_global_formref(), dwarf_formaddr(), +dwarf_formflag(), dwarf_formudata(), dwarf_formsdata(), dwarf_formblock, +dwarf_formstring() and tests for them. + +Version 0.2: + +Implemented dwarf_offdie()), dwarf_tag(), dwarf_dieoffset(), +dwarf_die_CU_offset(), dwarf_diename() and tests for them. + +Version 0.1: + +First libdwarf functions work. + +Version 0.0: + +libelf and parts of libebl are done. -- cgit v1.2.3
