2017-11-07readelf ngettext fixesAlan Modra15-21/+21
This patch is a first pass at fixing readelf message pluralization. I've deliberately not fixed the "out of memory" errors since it's very unlikely that they will ever be complaining about not being able to allocate for a single entry, and a few others where the size is very unlikely to be 1 byte. Then there are messages like this one: "Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n" I suppose this could be split into three parts, "Of %lu items ", "there are %zu bucket clashes ", and "(longest of %zu entries).\n", each part being printed separately, but that might not be ideal for sentence construction in other languages. For now I'm punting on this one. Changes to readelf output require lots of testsuite adjustment.. binutils/ * dwarf.c (read_uleb128): Properly pluralize messages.

2017-08-07Support different ld --hash-style in the ld testsuiteAlan Modra13-13/+13
When ld is running with something other than --hash-style=sysv by default, numerous tests need tweaking. Most of the changes just add --hash-style=sysv.

2017-05-08x86-64: Improve PLT generation and synthetic PLT symbolsH.J. Lu4-0/+129
On x86-64, the procedure linkage table (PLT) is used to 1. Call external function. 2. Call internal IFUNC function. The best implementation is selected for the target processor at run-time. 3. Act as the canonical function address. 4. Support LD_AUDIT to audit external function calls. 5. Support LD_PROFILE to profile external function calls. PLT looks like: PLT0: push GOT[1] jmp *GOT[2] nop PLT1: jmp *GOT[name1_index] push name1_reloc_index jmp PLT0 GOT is an array of addresses. Initially the GOT entry of name1 is filled with the address of the "push name1_reloc_index" instruction. The function, name1, is called via "jmp *GOT[name1]" in the PLT entry. Even when lazy binding is disabled by "-z now", the PLT0 entry may still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for canonical function address. When linker is invoked with "-z bndplt", a different PLT layout in .plt is used: PLT0: push GOT[1] bnd jmp *GOT[2] nop PLT1: push name1_reloc_index bnd jmp PLT0 nop together with a second PLT section, .pl.bnd: PLT1: bnd jmp *GOT[name1_index] nop where the GOT entry of name1 is filled with the address of the push instruction of the corresponding entry in .plt. 1. With lazy binding, when the external function, name1, is called the first time, dynamic linker is called via PLT0 to update GOT[name1_index] with the actual address of name1 and transfers control to name1 afterwards. 2. PLT is also used to call a local IFUNC function, name1, run-time loader updates GOT[name1_index] when loading the module. This patch 1. Remove PLT layout configurations from x86-64 backend_data. 2. Add generic, lay and non-lazy PLT layout configurations to x86-64 link_hash_table. Generic PLT layout includes the PLT entry templates, information how to update the first instruction in PLT and PLT eh_frame informaton, which are initialized in x86-64 setup_gnu_properties, based on "-z bndplt" and target selection. PLT section alignment is also set to PLT entry size for non-NaCl target. 3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections isn't always called, but GOT relocations need GOT relocations. Instead, create all x86-64 specific dynamic sections with alignment to their entry size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so that x86-64 check_relocs can be simplified. 4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against all dynamic relocations to support both lazy and non-lazy PLTs. There is no change in PLT. The only externally visible change is the improvement of synthetic PLT symbols for .plt.got. bfd/ * elf64-x86-64.c (PLT_ENTRY_SIZE): Renamed to ... (LAZY_PLT_ENTRY_SIZE): This.

2017-01-02Run more ld tests when not nativeAlan Modra2-42/+23
Many of the ld tests are not run for cross builds, in some cases because the test needs to run a newly linked executable, and in others simply because it was easier to write the test for native only. Even when a test needs to run, it's good to compile and link to exercise the linker. So that's what this patch does. I've also rid us of the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's much simpler to just link with $CC. This does mean that a cross build with cross-compiler installed but no cross C-library will give lots of failures. If that turns out to be too annoying, I guess we can write a tcl procedure to detect it and not run all the extra tests. * Makefile.am (bootstrap): Delete rule.

R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations retrieve the symbol address via its GOT slot. If the symbol address is known at the link-time, we can use it directly by changing instruction encoding. Indirect branch can only be converted to PC relative direct branch. MOV can be changed to LEA or encoded differently with signed address. The subset of binary operations can be encoded only with signed address. If undefined weak symbol is resolved to zero link-time, we can use it as address. Zero addresss can't used with PC relative direct branch when PIC is true since the current PC is unknown. In 64-bit, 32-bit relocation for PC relatiave direct branch to zero may also overflow. If this optimization causes relocation overflow, --no-relax can be used to work around it. bfd/ PR ld/19609 * elf32-i386.c (elf_i386_convert_load): Convert to R_386_32 for load with locally bound symbols if PIC is false or there is no base register.

The x86 relax relocations introduced in binutils 2.26 aren't supported by linker on Solaris older than Solaris 12. To use x86 assembler with older Solaris linker, this patch adds 1. A command line option -mrelax-relocations= to x86 assembler to control whether to generate relax relocations. 2. A configure option --enable-x86-relax-relocations to decide whether x86 assembler should generate relax relocations by default. It is defaulted to yes, except for x86 Solaris targets older than Solaris 12. gas/ PR gas/19520 * NEWS: Mention new command line option -mrelax-relocations and new configure option --enable-x86-relax-relocations for x86 target. * config.in: Regenerated. * configure.ac: Add --enable-x86-relax-relocations.

2014-01-21Check incompatible existing default symbol definitionH.J. Lu8-0/+76
After resolving a versioned reference, foo@VER1, to a default versioned definition, foo@@VER1, from a shared object, we also merge it with the existing regular default symbol definition, foo. When foo is IFUNC and foo@@VER1 aren't, we will merge 2 incompatible definitions. This patch avoids merging foo@@VER1 definition with foo definition if one is IFUNC and the other isn't.
