2014-06-07Allow both signed and unsigned fields in PowerPC cmpli insnAlan Modra1-0/+4
There are legitimate reasons to allow a signed value in a cmpli insn field, for example to test for a "stw r1,lock@sdarel(r13)" instruction in user code, a kernel might use subis r3,r3,STW_R1_0R13@ha # subtract off high part cmplwi r3,lock@sdarel # is low part accessing lock? Since the lock@sdarel may take a range of -32768 to 32767, the allowed range of cmpli immediate must be at least [-32768,65535]. bfd/ * elf32-ppc.c (ppc_elf_relocate_section): Treat field of cmpli insn as a bitfield; Use complain_overflow_bitfield. * elf64-ppc.c (ppc64_elf_relocate_section): Likewise. opcodes/ * ppc-opc.c (UISIGNOPT): Define and use with cmpli. gas/ * config/tc-ppc.c (ppc_insert_operand): Handle PPC_OPERAND_SIGNOPT on unsigned fields.

2014-06-06Strip .debug_gnu_pubnames and .debug_gnu_pubtypes when building .gdb_index.Cary Coutant1-0/+8
When not stripping those sections, there was a bug where gold was incorrectly adjusting section-relative offsets by the offset of the input section within the output section. That adjustment was both unnecessary and wrong, causing gold to miss a number of debug entries that should have been added to .gdb_index. (With stripping, the adjustment was always 0, so the bug in dwarf_reader.cc would have been hidden by the change to layout.cc.) gold/ * dwarf_reader.h (Dwarf_pubnames_table): Remove output_section_offset_. * dwarf_reader.cc (Dwarf_pubnames_table::read_section): Likewise. (Dwarf_pubnames_table::read_header): Likewise. * layout.cc (gdb_fast_lookup_sections): Add .debug_gnu_pubnames and .debug_gnu_pubtypes.
2014-06-05Make it easy to make --disable-werror the default for both binutils and gdbJoel Brobecker1-0/+5
The goal of this patch is to provide an easy way to make --disable-werror the default when building binutils, or the parts of binutils that need to get built when building GDB. In development mode, we want to continue making -Werror the default with GCC. But, when making releases, I think we want to make it as easy as possible for regular users to successfully build from sources. GDB already has this kind of feature to turn -Werror as well as the use of the libmcheck library. As GDB Release Manager, I take advantage of it to turn those off after having cut the branch. I'd like to be able to do the same for the binutils bits. And perhaps Tristan will want to do the same for his releases too (not sure, binutils builders might be a little savvier than GDB builders). This patch introduces a new file, called development.sh, which just sets a variable called $development. In our development branches (Eg. "master"), it's set to true. But setting it to false would allow us to change the default behavior of various development-related features to be turned off; in this case, it turns off the use of -Werror by default (use --enable-werror to turn it back on). bfd/ChangeLog: * development.sh: New file. * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh. Make -Werror the default with GCC only if DEVELOPMENT is true. * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add $(srcdir)/development.sh. * Makefile.in, configure: Regenerate. binutils/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gas/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gold/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): New. * Makefile.in, configure: Regenerate. gprof/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. ld/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. opcodes/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gdb/ChangeLog: * development.sh: Delete. * Makefile.in (config.status): Adjust dependency on development.sh. * configure.ac: Adjust development.sh source call. * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: Adjust development.sh source call. * Makefile.in (config.status): Adjust dependency on development.sh. * configure: Regenerate. Tested on x86_64-linux by building two ways: One with DEVELOPMENT set to true, and one with DEVELOPMENT set to false. In the first case, I could see the use of -Werror, while it disappeared in the second case.
2014-06-03Support fusion for ELFv2 stubsAlan Modra1-0/+5
Power8 fuses addis,addi and addis,ld sequences when the target of the addis is the same as the addi/ld. Thus addis r12,r2,xxx@ha addi r12,r12,xxx@l / ld r12,xxx@l(r12) is faster than addis r11,r2,xxx@ha addi r12,r11,xxx@l / ld r12,xxx@l(r11) So use the form that allows fusion in plt call and branch stubs. bfd/ * elf64-ppc.c (ADDIS_R12_R2): Define.

2014-05-27Properly handle 64-bit GOT relocationsH.J. Lu1-0/+6
This patch fixes 2 issues: 1. Since the GOT offset is always negative, we need to use signed int to support 64-bit GOT relocations. 2. R_X86_64_PLTOFF64 uses the address of GLOBAL_OFFSET_TABLE, which is the address of the .got.plt section, not the .got section.
2014-05-15Fix "overflow in PLT unwind data" warningAlan Modra1-31/+36
When linking statically, it's possible to hit this warning with IFUNC or very large executables, due to .glink being unused. * powerpc.cc (do_plt_fde_location): Handle zero length .glink. Compare FDE contents with DW_CFA_nop rather than 0.
2014-05-13With -pie and x86, the linker complains if it sees a PC-relative relocationSriraman Tallam1-0/+19
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.

2014-03-08Better overflow checking for powerpc64 relocationsAlan Modra1-0/+12
R_PPC64_ADDR16 is used in three contexts: - .short data relocation - 16-bit signed insn fields, eg. addi - 16-bit unsigned insn fields, eg. ori In the first case we want to allow both signed and unsigned 16-bit values, the latter two ought to error if the field exceeds the range of values allowed for 16-bit signed and unsigned integers respectively. These conflicting requirements meant that ld had to choose the least restrictive overflow checks, and thus it is possible to construct testcases where an addi field overflows but is not reported by ld. Many relocations dealing with 16-bit insn fields have this problem. What's more, some relocations that are only ever used for signed fields of instructions woodenly copied the lax overflow checking of R_PPC64_ADDR16. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Use complain_overflow_signed for R_PPC64_ADDR14, R_PPC64_ADDR14_BRTAKEN, R_PPC64_ADDR14_BRNTAKEN, R_PPC64_SECTOFF, R_PPC64_ADDR16_DS, R_PPC64_SECTOFF_DS, R_PPC64_REL16 entries.

2013-11-15Fixes to powerpc64 gold ELFv2 supportAlan Modra1-0/+35
* powerpc.cc (Target_powerpc::glink_section): Provide non-const accessor. (Target_powerpc::Branch_info::make_stub): Make global entry stubs. Only call ppc64_local_entry_offset for 64-bit. Restrict symval_for_branch lookup to ELFv1. (Stub_table::add_plt_call_entry): Use unsigned int off. (Output_data_glink::Address, invalid_address): New. (Output_data_glink::add_eh_frame): Move out of line. Add support for ELFv2. (Output_data_glink::add_global_entry, find_global_entry, global_entry_address): New functions. (Output_data_glink::global_entry_stubs_, end_branch_table_, ge_size): New variables. (Output_data_glink::set_final_data_size): Add global entry stub sizing. (Output_data_glink::do_write): Write global entry stubs. (Target_powerpc::Scan::reloc_needs_plt_for_ifunc): Add target parameter. Return true for ELFv2. Adjust callers. (Target_powerpc::Scan::local, global): Restrict opd lookup to ELFv1. Similarly for ifunc and dynamic relocation processing specific to ELFv1. Recognize that symbols are defined on their plt entries for ELFv2. (Target_powerpc::symval_for_branch): Assert if called for ELFv2 or ppc32. (Target_powerpc::Relocate::relocate): Use global entry plt stub for symbol value if such exists on ELFv2. (Target_powerpc::Relocate::relocate): Don't call symval_for_branch when ELFv2. Do adjust for local entry offset when ELFv2. (Target_powerpc::do_dynsym_value): Set symbols to global entry plt stub for ELFv2. (Target_powerpc::do_plt_address_for_global): Similarly.
