2021-09-18[GOLD] Output_data_got tidyAlan Modra1-30/+11
Some Output_data_got methods already have support for addends, but were implemented as separate methods. This removes unnecessary code duplication. Relobj::local_has_got_offset and others there get a similar treatment. Comments are removed since it should be obvious without a comment, and the existing comments are not precisely what the code does. For example, a local_has_got_offset call without an addend does not return whether the local symbol has *a* GOT offset of type GOT_TYPE, it returns whether there is a GOT entry of type GOT_TYPE for the symbol with addend of zero.

2021-09-18[GOLD] Remove addend from Local_got_entry_keyAlan Modra1-9/+6
This patch removes the addend from Local_got_entry_key, which is unnecessary now that Got_offset_list has an addend. Note that it might be advantageous to keep the addend in Local_got_entry_key when linking objects containing a large number of section_sym+addend@got relocations. I opted to save some memory by removing the field but left the class there in case we might need to restore {sym,addend} lookup. That's also why this change is split out from the Got_offset_list change. PR 28192 * object.h (Local_got_entry_key): Delete addend_ field.

This is the first in a series of patches aimed at supporting GOT entries against symbol plus addend generally for PowerPC64 rather than just section symbol plus addend as gold has currently. This patch adds an addend field to Got_offset_list, so that both local and global symbols can have GOT entries with addend.

2018-04-06Further improve warnings for relocations referring to discarded sections.Cary Coutant1-12/+31
Relocations referring to discarded sections are now treated as errors instead of warnings. Also with this patch, we will now print the section group signature and the object file with the prevailing definition of that group along with the name of the symbol that the relocation is referring to. This additional information should be much more useful to anyone trying to track down the source of such errors. To do so, we now map each discarded section to the Kept_section info in the Layout class, and defer the logic that maps a discarded section to its counterpart in the kept group. This gives us the information we need to identify the signature symbol given the discarded section, and the name of the object file that provided the prevailing (i.e., first) definition of that group. gold/ * object.cc (Sized_relobj_file::include_section_group): Store reference to Kept_section info for discarded comdat sections regardless of size.

2018-04-02Fix problem where mixed section types can cause internal error during a -r link.Cary Coutant1-4/+8
During a -r (or --emit-relocs) link, if two sections had the same name but different section types, gold would put relocations for both sections into the same relocation section even though the data sections remained separate. For .eh_frame sections, when one section is PROGBITS and another is X86_64_UNWIND, we really should be using the UNWIND section type and combining the sections anyway. For other sections, we should be creating one relocation section for each output data section. gold/ PR gold/23016 * incremental.cc (can_incremental_update): Check for unwind section type. * layout.h (Layout::layout): Add sh_type parameter. * layout.cc (Layout::layout): Likewise.

2017-11-28Allow multiple .eh_frame sections per object file.Cary Coutant1-3/+0
LLVM is experimenting with placing .eh_frame sections in the COMDAT group with the function's text. This triggers an internal error in gold because we don't expect to see but one .eh_frame section in an object, and we use a single data member in class Sized_relobj_file to keep track of that section. This patch removes that data member, and instead checks the output section and the input section offset to identify an optimized .eh_frame section. gold/ * object.h (class Sized_relobj_file): Remove discarded_eh_frame_shndx_. * object.cc (Sized_relobj_file::Sized_relobj_file): Likewise.

2017-11-27Fix symbol values and relocation addends for relocatable links.Cary Coutant1-1/+3
The fix for PR 19291 broke some other cases where -r is used with scripts, as reported in PR 22266. The original fix for PR 22266 ended up breaking many cases for REL targets, where the addends are stored in the section data, and are not being adjusted properly. The problem was basically that in a relocatable output file (ET_REL), symbol values are supposed to be relative to the start address of their section. Usually in a relocatable file, all sections start at 0, so the failure to get this right is often irrelevant, but with a linker script, we occasionally see an output section whose starting address is not 0, and gold would occasionally write a symbol with its relocated value instead of its section-relative value. This patch reverts the recent fix for PR 22266 as well as my original fix for PR 19291. The original fix moved the symbol value adjustment to write_local_symbols, but neglected to undo a few places where the adjustment was also being applied, resulting in an occasional double adjustment. The more recent fix removed those other adjustments, but then failed to re-account for the adjustment when rewriting the relocations on REL targets. With the old attempts reverted, we now apply the symbol value adjustment to the one case that had been missed (non-section symbols in merge sections). But now we also need to account for the adjustment when rewriting the addends for RELA relocations. gold/ PR gold/19291 PR gold/22266 * object.cc (Sized_relobj_file::compute_final_local_value_internal): Revert changes from 2017-11-08 patch.

2016-01-11Refactor gold to enable support for MIPS-64 relocation format.Cary Coutant1-2/+4
For MIPS-64, the r_info field in the relocation format is replaced by several individual fields, including r_sym and r_type. To enable support for this format, I've refactored target-independent code to remove almost all uses of the r_info field. (I've left alone a couple of routines used only for incremental linking, which I can update if/when the MIPS target adds support for incremental linking.) For routines that are already templated on a Classify_reloc class (namely, gc_process_relocs, relocate_section, and relocate_relocs), I've extended the Classify_reloc interface to include sh_type (which no longer needs to be a separate template parameter) as well as get_r_sym() and get_r_type() methods for extracting the r_sym and r_type fields. For scan_relocatable_relocs, I've extended the Default_scan_relocatable_relocs class by converting it to a class template with Classify_reloc as a template parameter. For the remaining routines that need to access r_sym, I've added a virtual Target::get_r_sym() method with an override for the MIPS target. In elfcpp, I've added Mips64_rel, etc., accessor classes and corresponding internal data structures. The MIPS target uses these new classes within its own Mips_classify_reloc class. The Mips64_ accessor classes also expose the r_ssym, r_type2, and r_type3 fields from the relocation. These changes should be functionally the same for all but the MIPS target. elfcpp/ * elfcpp.h (Mips64_rel, Mips64_rel_write): New classes.

2015-12-09[GOLD] Relocate::relocate() paramsAlan Modra1-0/+2
Some linker code editing needs to change multiple insns. In some cases multiple relocations are involved and it is not sufficient to make the changes independently as relocations are processed, because doing so might lead to a partial edit. So in order to safely edit we need all the relocations available in relocate(). Also, to emit edited relocs corresponding to the edited code sequence we need some way to pass information from relocate() to relocate_relocs(), particularly if the edit depends on insns. We can't modify input relocs in relocate() as they are mmapped PROT_READ, nor it is particularly clean to write relocs to the output at that stage. So add a Relocatable_relocs* field to relinfo to mark edited relocs. Given that relocate is passed the raw reloc pointer, it makes sense to remove the rel/rela parameter and r_type too. However, that means the mips relocate() needs to know whether SHT_REL or SHT_RELA relocs are being processed. So add a rel_type for mips, which also has the benefit of removing relocate() overloading there. This patch adds the infrastructure without making use of it. Note that relinfo->rr will be NULL if not outputting relocations. * object.h (struct Relocate_info): Add "rr". * reloc.h (Relocatable_relocs::set_strategy): New accessor. * reloc.cc (Sized_relobj_file::do_relocate_sections): Init relinfo.rr for relocate_section and relocate_relocs. * powerpc.cc (relocate): Add rel_type and preloc parameters.

2015-08-25Fix --no-as-needed when shared library is listed twice on the command line.Cary Coutant1-1/+6
When a shared library is listed twice on the command line, the linker ignores the second mention. If the first mention is in the scope of an --as-needed option, and the second one is under the scope of a --no-as-needed option, the --no-as-needed should take effect, but doesn't. This patch keeps track of the objects we've already seen, and updates the --as-needed flag so that if a shared object is ever seen with --no-as-needed, it will be marked as such. gold/ PR gold/18859 * object.cc (Input_objects::add_object): Store objects in a map, indexed by soname; update as-needed flag when necessary. * object.h (Object::clear_as_needed): New method.
