1 ToDo list for elfutils -*-outline-*-
4 Time-stamp: <2009-01-01 16:56:38 drepper>
8 Remove everywhere. Use mkdir -p.
14 Currently the elf_update function trusts the user blindly if the
15 ELF_F_LAYOUT flag is set. This is OK if the data is prepared by a
16 ELF_C_NULL call but not if the user prepared the data herself
18 ** break out archive handling from elf_begin
20 The handling of archives (especially of the symbol tables) must be
21 broken out of elf_begin. There are several different forms of
22 archives and only when having the archive handling separately this
28 ** More memory access checks needed
30 All accesses to the debug sections should make sure the offsets are
31 valid. This is currently especially a problem with leb128 accesses.
33 ** Low level macro information operations
35 in 5.11.3 are not implemented. gcc currently does not emit this
36 information so I cannot test it.
38 ** Rename dwarf_getabbrev
57 ** add demangler support
59 Use demangler from libiberty.
61 ** add support to read debugging symbols
63 Implement -l option for BSD and POSIX format
68 ** support SHT_SYMTAB_SHNDX
70 should be removed if not needed anymore
74 ** sanity check .rel sh_info content
76 the sh_info of all .rel sections with the same name must point to
77 sections which also have the same name
81 to locate shared libraries also use /etc/ld.so.conf
83 ** handle object files for different architectures
85 ld.so is expected to ignore object files for different architectures and
86 continue looking for a matching file (e.g., ignore 32-bit binaries on
87 64-bit platforms and vice versa). We probably need the same in ld.
89 ** reuse after elf_end
91 Some files are closed using elf_end. They are removed from memory only
92 if no reference is left (especially for archives this is a problem).
93 The old mapping should be reused in that case. The problem is worse
94 for files which are not mapped read-only (archives again).
96 ** size for STT_SECTION entries
98 The STT_SECTION entries have zero for the size but can easily get
99 the size of the section.
103 Not implemented at all in the moment except for recognition of the option
110 1st GOT entry == _DYNAMIC
112 check versioning info:
114 always BASE in verdef
115 sh_size/sh_entsize matches last offset != 0
117 check whether any relocation is for a merge-able section
119 check TLS relocation depencies
123 check that R_386_TLS_GD is followed by R_386_PLT32 for __tls_get_addr
127 prelink generated files
131 ** treat relocation sections special
133 Differences in the relocation sections can be ignored if all
134 the same symbols with the same targets are present and the order
135 of overlapping relocations doesn't change. There really never
136 should be overlapping relocations but who knows.
140 Sun has it. Can modify sections which are not in segments.
143 Append string to the comment section of the ELF object
144 files. If string contains embedded blanks, it must be
145 enclosed in quotation marks.
147 -c Compress the contents of the comment section of the
148 ELF object files. All duplicate entries are removed.
149 The ordering of the remaining entries is not dis-
152 -d Delete the contents of the comment section from the
153 ELF object files. The section header for the comment
154 section is also removed.
157 Specify the name of the comment section to access if
158 other than .comment. By default, mcs deals with the
159 section named .comment. This option can be used to
160 specify another section. mcs can take multiple -n
161 options to allow for specification of multiple sec-
164 -p Print the contents of the comment section on the stan-
165 dard output. Each section printed is tagged by the
166 name of the file from which it was extracted, using
167 the format file[member_name]: for archive files and
168 file: for other files.
170 -V Print on standard error the version number of mcs.
