2016-01-11Refactor gold to enable support for MIPS-64 relocation format.Cary Coutant1-20/+73
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 Modra1-15/+10
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.

2015-07-09Drop 'missing mapping symbols' warning for arm and aarch64.Han Shen1-9/+2
The psABI (AAELF) says this about mapping symbols: 4.6.5.1 Section-relative mapping symbols Mapping symbols defined in a section define a sequence of half-open address intervals that cover the address range of the section. Each interval starts at the address defined by the mapping symbol, and continues up to, but not including, the address defined by the next (in address order) mapping symbol or the end of the section. A section must have a mapping symbol defined at the beginning of the section; however, if the section contains only data then the mapping symbol may be omitted. That makes it pretty clear that, in the absence of a mapping symbol, the entire section can be treated as data. gold/ChangeLog: * aarch64.cc (AArch64_relobj::scan_errata): Drop missing symbol warning. * arm.cc (Arm_relobj::scan_section_for_cortex_a8_erratum): Drop missing symbol warning.

2014-05-13With -pie and x86, the linker complains if it sees a PC-relative relocationSriraman Tallam1-2/+4
to access a global as it expects a GOTPCREL relocation. This is really not necessary as the linker could use a copy relocation to get around it. This patch enables copy relocations with pie. Context: This is useful because currently the GCC compiler with option -fpie makes every extern global access go through the GOT. That is because the compiler cannot tell if a global will end up being defined in the executable or not and is conservative. This ends up hurting performance when the binary is linked as mostly static where most of the globals do end up being defined in the executable. By allowing copy relocs with fPIE, the compiler need not generate a GOTPCREL(GOT access) for any global access. It can safely assume that all globals will be defined in the executable and generate a PC-relative access instead. Gold can then create a copy reloc for only the undefined globals. gold/ * symtab.h (may_need_copy_reloc): Remove check for position independent code. * x86_64.cc (Target_x86_64<size>::Scan::global): Add check for no position independence before pc absolute may_need_copy_reloc call.

(Target::do_define_standard_symbols): Same. * testsuite/Makefile.am (arm_exidx_test): Dump relocations also. * testsuite/Makefile.in: Regenerate. * testsuite/arm_exidx.s: Generate data relocations for __exidx_start and __exidx_end. * testsuite/arm_exidx_test.sh: Check that no unused dynamic relocations are generated for __exidx_start and __exidx_end.

* arm.cc (Target_arm::got_section): Make .got section read-only if -z now is given.

* gold/arm.cc (Target_arm::Scan::global): Generate R_ARM_GLOB_DAT dynamic relocations for protected symbols in shared objects.

* arm.cc (Arm_relocate_functions::abs8, Arm_relocate_functions::abs16): Use Bits::has_signed_unsigned_overflow32. (Arm_relocate_functions::thm_abs8): Correct range of overflow check. * reloc.h (Bits class): Change minimum number of bits from 0 to 1 in assertions.

* arm.cc (Reloc_stub::stub_type_for_reloc): Use PIC stubs in all position independent outputs, not just shared objects.
2012-01-28 * reloc.h (Bits): New class with static functions, copied fromIan Lance Taylor1-103/+46
namespace utils in arm.cc. * arm.cc (namespace utils): Remove. Rewrite all uses to use Bits instead.
