This patch standardizes messages in ld, to better conform to the GNU coding standard. Besides issues of capitalization and full-stops, I've - Split up help messages for target options, so that adding a new option does not mean loss of translation for all the others. - Embedded tabs have been removed, since a user might have tab stops set at other than 8 char intervals. - Added missing program name (%P). ld isn't the compiler. - Put %F and %X first (and removed %X if %F was present). These can go anywhere, but look silly in the m%Fiddle of a message, and choosing "%P%F:" in some messages but "%F%P:" in others leads to the likelihood of duplication in ld.pot.

2018-01-28PR22751, LTO broken for libgcc libcallsAlan Modra1-1/+2
So what was happening was that the file added from libgcc.a during the rescan was not put on file_chain. map_input_to_output_sections then doesn't see the file and its sections are treated as discarded. The file_chain list pointer bug was caused by that fact that an archive element claimed by the plugin does not have my_archive set. Or more correctly, the actual archive element does have my_archive set, but this bfd is replaced with a dummy bfd that doesn't have my_archive set.

2018-01-11ld: Fix issue where PROVIDE overrides defined symbolAndrew Burgess1-0/+1
In a linker script, a sequence like this: foo = ADDR (.some_section); bar = foo; PROVIDE (foo = 0); will result in 'bar = ADDR (.some_section)' and 'foo = 0', which seems like incorrect behaviour, foo is clearly defined elsewhere, and so the PROVIDE should not trigger. The problem is that an expression like this: foo = ADDR (.some_section); can't be evaluated until a late phase of the linker, due to the need for the section '.some_section' to have been placed, then the PROVIDE was being marked as being used during an earlier phase. At the end of the link, both lines: foo = ADDR (.some_section); PROVIDE (foo = 0); are active, and this causes the final value of 'foo' to be 0. The solution proposed in this commit is that, during earlier phases of the linker, when we see the expression 'foo = ADDR (.some_section);', instead of ignoring the expression, we create a "fake" definition of 'foo'. The existence of this "fake" definition prevents the PROVIDE from being marked used, and during the final phase the real definition of 'foo' will replace the "fake" definition. The new test provide-6 covers the exact case described above. The provide-7 test is similar to the above, but using constant expressions, this was never broken, but is added here to increase coverage. The provide-8 case also didn't fail before this commit, but I did manage to break this case during development of this patch. This case was only covered by a mmix test before, so I've added this here to increase coverage. ld/ChangeLog: * ldexp.c (exp_fold_tree_1): Rework condition underwhich provide nodes are ignored in the tree walk, and move the location at which we change provide nodes into provided nodes.

2017-11-28PR22471, undefined reference to linker-defined symbolsAlan Modra1-3/+3
This patch processes linker script assignment statements before ld opens DT_NEEDED libraries, in order to define symbols like __bss_start that might also be defined by a library, falsely triggering an error about "DSO missing from command line". The initial value won't be correct when assigning a symbol from dot, and I make no attempt to handle all expressions. For example, an assignment like "_start_foo = ADDR (.foo)" isn't valid until sections are laid out, so won't define _start_foo early. What's here should be enough for most common scripts, and hopefully won't perturb fragile scripts. bfd/ PR 22471 * elflink.c (_bfd_elf_merge_symbol): Allow weak symbols to override early passes over linker script symbols. * linker.c (_bfd_generic_link_add_one_symbol): Allow symbols to override early passes over linker script symbols.

2017-10-16ELF: Call check_relocs after opening all inputsH.J. Lu1-0/+2
For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got.

ld ought to be more clever about where it puts LTO recompiled objects. Ideally the recompiled objects ought to be ordered to the same place their IR objects were, and files extracted from archives on the second pass ought to go in the same place as they would if extracted on the first pass. This patch addresses the archive problem. Without this fix, objects extracted from archives might be placed after the crt files intended to go at the end of an executable or shared library, possibly causing exception handling failures. * ldlang.h (lang_input_statement_type): Expand comments.

2017-08-24ld: Early detection of orphans we know will be discardedAndrew Burgess1-15/+31
When processing an orphan section we first call lang_place_orphans, this function handles a few sections for which the behaviour is known COMMON sections, or sections marked as SEC_EXCLUDE. Any orphans that are not handled in lang_place_orphans are passed on to ldlang_place_orphan, this is where we decide where to put the orphan, and then call lang_add_section to perform the actual orphan placement. We previously had a larger set of checks at the start of the function lang_add_section to discard some sections that we _knew_ should not be added into the output file, this was where .group sections (in a final link) and .debug* sections (with --strip-debug) were dropped. The problem with dropping these sections at the lang_add_section stage is that a user might also be using --orphan-handling=error to prevent orphans. If they are then they should not be get errors about sections that we know will be discarded, and which are not mentioned in the linker script. The solution proposed in this patch is to move the "will this section be discarded" check into a separate function, and use this in lang_place_orphans to have the early discard phase discard sections that we know should not be included in the output file. ld/ChangeLog: PR 21961 * ldlang.c (lang_discard_section_p): New function.

2017-08-06Treat common symbol as undefined for --no-define-commonH.J. Lu1-1/+1
When --no-define-common is used to build shared library, treat common symbol as undefined so that common symbols that are referenced from a shared library to be assigned addresses only in the main program. This eliminates the unused duplicate space in the shared library, and also prevents any possible confusion over resolving to the wrong duplicate when there are many dynamic modules with specialized search paths for runtime symbol resolution. --no-define-common is only allowed when building a shared library. bfd/ PR ld/21903: * elflink.c (elf_link_add_object_symbols): Treat common symbol as undefined for --no-define-common. include/ PR ld/21903: * bfdlink.h (bfd_link_info): Add inhibit_common_definition. ld/ PR ld/21903: * ld.h (command_line): Remove inhibit_common_definition. * ldgram.y: Replace command_line.inhibit_common_definition with link_info.inhibit_common_definition. * ldlang.c (lang_common): Likewise. * lexsup.c (parse_args): Likewise. * ldmain.c (main): Only allow --no-define-common with -shared. * testsuite/ld-elf/pr21903.s: New file. * testsuite/ld-elf/pr21903a.d: Likewise. * testsuite/ld-elf/pr21903b.d: Likewise. * testsuite/ld-elf/pr21903c.d: Likewise. * testsuite/ld-elf/pr21903d.d: Likewise. * testsuite/ld-elf/pr21903e.d: Likewise.

2017-06-16Rewrite __start and __stop symbol handlingAlan Modra1-70/+163
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

2017-06-13Always define referenced __start_SECNAME/__stop_SECNAMEH.J. Lu1-61/+54
Currently, linker will define __start_SECNAME and __stop_SECNAME symbols only for orphaned sections. However, during garbage collection, ELF linker marks all sections with references to __start_SECNAME and __stop_SECNAME symbols as used even when section SECNAME isn't an orphaned section and linker won't define __start_SECNAME nor __stop_SECNAME. And ELF linker stores the first input section whose name matches __start_SECNAME or __stop_SECNAME in u.undef.section for garbage collection. If these symbols are provided in linker script, u.undef.section is set to the section where they will defined by linker script, which leads to the incorrect output. This patch changes linker to always define referenced __start_SECNAME and __stop_SECNAME if the input section name is the same as the output section name, which is always true for orphaned sections, and SECNAME is a C identifier. Also __start_SECNAME and __stop_SECNAME symbols are marked as hidden by ELF linker so that __start_SECNAME and __stop_SECNAME symbols for section SECNAME in different modules are unique. For garbage collection, ELF linker stores the first matched input section in the unused vtable field. bfd/ PR ld/20022 PR ld/21557 PR ld/21562 PR ld/21571 * elf-bfd.h (elf_link_hash_entry): Add start_stop.

2017-06-06ld: Allow section groups to be resolved as part of a relocatable linkAndrew Burgess1-3/+15
This commit adds a new linker feature: the ability to resolve section groups as part of a relocatable link. Currently section groups are automatically resolved when performing a final link, and are carried through when performing a relocatable link. By carried through this means that one copy of each section group (from all the copies that might be found in all the input files) is placed into the output file. Sections that are part of a section group will not match input section specifiers within a linker script and are forcibly kept as separate sections. There is a slight resemblance between section groups and common section. Like section groups, common sections are carried through when performing a relocatable link, and resolved (allocated actual space) only at final link time. However, with common sections there is an ability to force the linker to allocate space for the common sections when performing a relocatable link, there's currently no such ability for section groups. This commit adds such a mechanism. This new facility can be accessed in two ways, first there's a command line switch --force-group-allocation, second, there's a new linker script command FORCE_GROUP_ALLOCATION. If one of these is used when performing a relocatable link then the linker will resolve the section groups as though it were performing a final link, the section group will be deleted, and the members of the group will be placed like normal input sections. If there are multiple copies of the group (from multiple input files) then only one copy of the group members will be placed, the duplicate copies will be discarded. Unlike common sections that have the --no-define-common command line flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no way to prevent group resolution during a final link, this is because the ELF gABI specifically prohibits the presence of SHT_GROUP sections in a fully linked executable. However, the code as written should make adding such a feature trivial, setting the new resolve_section_groups flag to false during a final link should work as you'd expect. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Don't initially mark SEC_GROUP sections as SEC_EXCLUDE.

2017-04-04PR ld/21233: Avoid sweeping forced-undefined symbols in section GCMaciej W. Rozycki1-0/+2
Complement commit 902e9fc76a0e ("PR ld/20828: Move symbol version processing ahead of GC symbol sweep"), commit b531344c34b0 ("PR ld/20828: Reorder the symbol sweep stage of section GC") and commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC"), and prevent symbols forcibly entered in the output file with the use of the `--undefined=' or `--require-defined=' linker command line options or the EXTERN linker script command from being swept in section garbage collection and consequently recorded in the dynamic symbol table as local entries. This happens in certain circumstances, where a symbol reference also exists in one of the static input files, however only in a section which is garbage-collected and does not make it to the output file, and the symbol is defined in a dynamic object present in the link. For example with the `i386-linux' target and the `pr21233.s' and `pr21233-l.s' sources, and the `pr21233.ld' linker script included with this change we get: $ as -o pr21233-l.o pr21233-l.s $ ld -shared -T pr21233.ld -o libpr21233.so pr21233-l.o $ as -o pr21233.o pr21233.s $ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so $ readelf --dyn-syms pr21233 Symbol table '.dynsym' contains 2 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 OBJECT LOCAL DEFAULT UND bar $ which makes the run-time `bar' dependency of the `pr21233' executable different from its corresponding link-time dependency, i.e. the presence of `libpr21233.so' and its `bar' symbol is required at the link time, however at the run time a copy of `libpr21233.so' without `bar' will do. Similarly with `--undefined=' and EXTERN which do not actually require the reference to the symbol requested to be satisfied with a definition at the link time, however once the definition has been pulled at the link time, so it should at the dynamic load time. Additionally with the `mips-linux' target we get: $ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so ld: BFD (GNU Binutils) 2.28.51.20170324 assertion fail .../bfd/elfxx-mips.c:3861 $ as the target is not prepared to handle such a local dynamic symbol. With this change in effect we get: $ readelf --dyn-syms pr21233 Symbol table '.dynsym' contains 2 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 OBJECT GLOBAL DEFAULT UND bar $ instead, for both targets. ld/ PR ld/21233 * ldlang.c (insert_undefined): Set `mark' for ELF symbols. * testsuite/ld-elf/pr21233.sd: New test. * testsuite/ld-elf/pr21233-l.sd: New test. * testsuite/ld-elf/pr21233.ld: New test linker script. * testsuite/ld-elf/pr21233-e.ld: New test linker script. * testsuite/ld-elf/pr21233.s: New test source. * testsuite/ld-elf/pr21233-l.s: New test source. * testsuite/ld-elf/shared.exp: Run the new tests.

2017-03-09ld: Track changes to default region LMA even for empty sectionsAndrew Burgess1-4/+10
Given a linker script fragment like this: SECTIONS { . = 0x1000; .text : AT(0x100) { *(.text) } .data : AT(0x200) { *(.data) } .rodata : AT(0x300) { *(.rodata) } } and an input file containing sections, '.text', '.data.1', and '.rodata', then we'd expect the linker to place '.text' and '.rodata' in the obvious way, and the '.data.1' orphan section would be located after the '.data' section (assuming similar section properties). Further, I believe that the expectation would be that the LMA for the orphan '.data.1' section would start from 0x200 (as there is no '.data' content). However, right now, the LMA for '.data.1' would be 0x101, following on from the '.text' section, this is because the change in LMA for the '.data' section is not noticed by the linker, if there's no content in the '.data' section. What can be even more confusing to a user (though the cause is obvious once you understand what's going on) is that adding some content to '.data' will cause the orphan '.data.1' to switch to an LMA based off of 0x200. This commit changes the behaviour so that an empty section that is in the default lma region, and sets its lma, will adjust the lma of the default region, this change will then be reflected in following sections within the default lma memory region. There's a new test to cover this issue that passes on a range of targets, however, some targets generate additional sections, or have stricter memory region size requirements that make it harder to come up with a generic pass pattern, that still tests the required features. For now I've set the test to ignore these targets. ld/ChangeLog: * ldlang.c (lang_size_sections_1): Shortcut loop only after tracking changes to the default regions LMA. * testsuite/ld-elf/orphan-9.ld: Extend header comment. * testsuite/ld-elf/orphan-10.d: New file. * testsuite/ld-elf/orphan-10.s: New file. * NEWS: Mention change in behaviour.
2017-03-09ld: better handling of lma region for orphan sectionsAndrew Burgess1-10/+24
When picking an lma_region for an orphan section we currently create a new lang_output_section_statement_type and then populate this with the orphan section. The problem is that the lang_output_section_statement_type has a prev pointer that links back to the previous output section. For non-orphan output sections, that are created in linker script order, the prev pointer will point to the output section that appears previous in linker script order, as you'd probably expect. The problem is that orphan sections are placed after processing the linker script, and so, in the case of an output section created for an orphan input section, the prev pointer actually points to the last output section created. This causes some unexpected behaviour when the orphan section is not placed after the last non-orphan section that was created. For example, consider this linker script: MEMORY { TEXT : ORIGIN = 0x200, LENGTH = 0x10 RODATA : ORIGIN = 0x400, LENGTH = 0x10 } SECTIONS { .text : {*(.text) } AT>TEXT .data : AT(0x300) { *(.data) } .rodata : { *(.rodata) } AT>RODATA } If we are processing an orphan section '.data.1' and decide to place this after '.data', then the output section created will have a prev pointer that references the '.rodata' output section. The result of this is that '.data.1' will actually be assigned to the RODATA lma region, which is probably not the expected behaviour. The reason why '.data.1' is placed into the lma region of the '.rodata' section is that lma region propagation is done at the time we create the output section, based on the previous output section pointer, which is really just a last-output-section-created pointer at that point in time, though the prev point is fixed up later to reflect the true order of the output sections. The solution I propose in this commit is to move the propagation of lma regions into a separate pass of the linker, rather than performing this as part of the enter/exit of output sections during linker script parsing. During this later phase we have all of the output sections to hand, and the prev/next points have been fixed up by this point to reflect the actual placement ordering. There's a new test to cover this issue that passes on a range of targets, however, some targets generate additional sections, or have stricter memory region size requirements that make it harder to come up with a generic pass pattern, that still tests the required features. For now I've set the test to ignore these targets. ld/ChangeLog: * ldlang.c (lang_leave_output_section_statement): Move lma_region logic to... (lang_propagate_lma_regions): ...this new function.

2016-11-04ld: Allow EXCLUDE_FILE to be used outside of the section listAndrew Burgess1-16/+43
Currently the EXCLUDE_FILE linker script construct can only be used within the input section list, and applied only to the section pattern immediately following the EXCLUDE_FILE. For example: *.o (EXCLUDE_FILE (a.o) .text .rodata) In this case all sections matching '.text' are included from all files matching '*.o' but not from the file 'a.o'. All sections matching '.rodata' are also included from all files matching '*.o' (incluing from 'a.o'). If the user wants to restrict the inclusion of section '.rodata' so that this too is not taken from the file 'a.o' then the above example must be extended like this: *.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata) However, due to the internal grammar of the linker script language the snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called 'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse the input file name snippet '*.o' in the above examples. As a result of this pattern reuse within the linker script grammar then the following is also a valid linker script construct: EXCLUDE_FILE (a.o) *.o (.text .rodata) However, though the linker accepts this without complaint the EXCLUDE_FILE part is silently ignored and has no effect. This commit takes this last example and makes it a useful, valid, construct. The last example now means to include sections '.text' and '.rodata' from all files matching '*.o' except for the file 'a.o'. If the list of input sections is long, and the user knows that the file exclusion applies across the list then the second form might be a clearer alternative to replicating the EXCLUDE_FILE construct. I've added a set of tests for EXCLUDE_FILE to the linker, including tests for the new functionality. ld/ChangeLog: * ldlang.h (struct lang_wild_statement_struct): Add exclude_name_list field. * ldlang.c (walk_wild_file_in_exclude_list): New function.

2016-10-11Always descend into output section statements in lang_do_assignmentsAlan Modra1-15/+23
See https://sourceware.org/ml/binutils/2016-07/msg00091.html This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols that ought to remain global. The difficulty with always descending into output section statements is that symbols defined by the script in such statements don't have a bfd section when lang_do_assignments runs early in the link process. There are two approaches to curing this problem. Either we can create the bfd section early, or we can use a special section. This patch takes the latter approach and uses bfd_und_section. (Creating bfd sections early results in changed output section order, and thus lots of testsuite failures. You can't create all output sections early to ensure proper ordering as KEEP then stops empty sections from being stripped.) The wrinkle with this approach is that some code that runs at gc-sections time needs to be made aware of the odd defined symbols using bfd_und_section. bfd/ * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Handle symbols defined temporarily with bfd_und_section. * elflink.c (_bfd_elf_gc_keep): Don't set SEC_KEEP for bfd_und_section. * elfxx-mips.c (mips_elf_local_pic_function_p): Exclude defined symbols with bfd_und_section. ld/ * ldlang.c (lang_do_assignments_1): Descend into output section statements that do not yet have bfd sections.

2016-09-30Make bfd_error_handler_type like vprintfAlan Modra1-1/+2
It was like printf, which means you can't use bfd_set_error_handler to hook in a function to do something and then call the original handler.
