2017-12-06BFD whitespace fixesAlan Modra
Binutils is supposed to use tabs. In my git config I have whitespace = indent-with-non-tab,space-before-tab,trailing-space and I got annoyed enough seeing red in "git diff" output to fix the problems. * doc/header.sed: Trim trailing space when splitting lines. * aix386-core.c, * aout-adobe.c, * aout-arm.c, * aout-cris.c, * aout-ns32k.c, * aout-target.h, * aout-tic30.c, * aoutf1.h, * aoutx.h, * arc-got.h, * arc-plt.def, * arc-plt.h, * archive.c, * archive64.c, * archures.c, * armnetbsd.c, * bfd-in.h, * bfd.c, * bfdio.c, * binary.c, * bout.c, * cache.c, * cisco-core.c, * coff-alpha.c, * coff-apollo.c, * coff-arm.c, * coff-h8300.c, * coff-i386.c, * coff-i860.c, * coff-i960.c, * coff-m68k.c, * coff-m88k.c, * coff-mcore.c, * coff-mips.c, * coff-ppc.c, * coff-rs6000.c, * coff-sh.c, * coff-stgo32.c, * coff-tic4x.c, * coff-tic54x.c, * coff-tic80.c, * coff-we32k.c, * coff-x86_64.c, * coff-z80.c, * coff-z8k.c, * coff64-rs6000.c, * coffcode.h, * coffgen.c, * cofflink.c, * coffswap.h, * compress.c, * corefile.c, * cpu-alpha.c, * cpu-arm.c, * cpu-avr.c, * cpu-bfin.c, * cpu-cr16.c, * cpu-cr16c.c, * cpu-crx.c, * cpu-d10v.c, * cpu-frv.c, * cpu-ft32.c, * cpu-i370.c, * cpu-i960.c, * cpu-ia64-opc.c, * cpu-ip2k.c, * cpu-lm32.c, * cpu-m32r.c, * cpu-mcore.c, * cpu-microblaze.c, * cpu-mips.c, * cpu-moxie.c, * cpu-mt.c, * cpu-nios2.c, * cpu-ns32k.c, * cpu-or1k.c, * cpu-powerpc.c, * cpu-pru.c, * cpu-sh.c, * cpu-spu.c, * cpu-v850.c, * cpu-v850_rh850.c, * cpu-xgate.c, * cpu-z80.c, * dwarf1.c, * dwarf2.c, * ecoff.c, * ecofflink.c, * ecoffswap.h, * elf-bfd.h, * elf-eh-frame.c, * elf-hppa.h, * elf-m10200.c, * elf-m10300.c, * elf-s390-common.c, * elf-strtab.c, * elf-vxworks.c, * elf.c, * elf32-am33lin.c, * elf32-arc.c, * elf32-arm.c, * elf32-avr.c, * elf32-avr.h, * elf32-bfin.c, * elf32-cr16.c, * elf32-cr16c.c, * elf32-cris.c, * elf32-crx.c, * elf32-d10v.c, * elf32-d30v.c, * elf32-dlx.c, * elf32-epiphany.c, * elf32-fr30.c, * elf32-frv.c, * elf32-ft32.c, * elf32-h8300.c, * elf32-hppa.c, * elf32-i386.c, * elf32-i860.c, * elf32-i960.c, * elf32-ip2k.c, * elf32-lm32.c, * elf32-m32c.c, * elf32-m32r.c, * elf32-m68hc11.c, * elf32-m68hc12.c, * elf32-m68hc1x.c, * elf32-m68hc1x.h, * elf32-m68k.c, * elf32-m88k.c, * elf32-mcore.c, * elf32-mep.c, * elf32-metag.c, * elf32-microblaze.c, * elf32-mips.c, * elf32-moxie.c, * elf32-msp430.c, * elf32-mt.c, * elf32-nds32.c, * elf32-nds32.h, * elf32-nios2.c, * elf32-or1k.c, * elf32-pj.c, * elf32-ppc.c, * elf32-ppc.h, * elf32-pru.c, * elf32-rl78.c, * elf32-rx.c, * elf32-s390.c, * elf32-score.c, * elf32-score.h, * elf32-score7.c, * elf32-sh-symbian.c, * elf32-sh.c, * elf32-sh64.c, * elf32-sparc.c, * elf32-spu.c, * elf32-tic6x.c, * elf32-tilegx.c, * elf32-tilegx.h, * elf32-tilepro.c, * elf32-tilepro.h, * elf32-v850.c, * elf32-vax.c, * elf32-wasm32.c, * elf32-xc16x.c, * elf32-xgate.c, * elf32-xgate.h, * elf32-xstormy16.c, * elf32-xtensa.c, * elf64-alpha.c, * elf64-hppa.c, * elf64-ia64-vms.c, * elf64-mips.c, * elf64-mmix.c, * elf64-ppc.c, * elf64-s390.c, * elf64-sh64.c, * elf64-sparc.c, * elf64-tilegx.c, * elf64-tilegx.h, * elf64-x86-64.c, * elfcore.h, * elflink.c, * elfn32-mips.c, * elfnn-aarch64.c, * elfnn-ia64.c, * elfnn-riscv.c, * elfxx-aarch64.c, * elfxx-aarch64.h, * elfxx-ia64.c, * elfxx-ia64.h, * elfxx-mips.c, * elfxx-riscv.c, * elfxx-sparc.c, * elfxx-tilegx.c, * elfxx-x86.c, * elfxx-x86.h, * freebsd.h, * hash.c, * host-aout.c, * hp300hpux.c, * hppabsd-core.c, * hpux-core.c, * i386aout.c, * i386linux.c, * i386lynx.c, * i386mach3.c, * i386msdos.c, * i386netbsd.c, * ieee.c, * ihex.c, * irix-core.c, * libaout.h, * libbfd-in.h, * libbfd.c, * libcoff-in.h, * libnlm.h, * libpei.h, * libxcoff.h, * linker.c, * lynx-core.c, * m68k4knetbsd.c, * m68klinux.c, * m68knetbsd.c, * m88kmach3.c, * mach-o-aarch64.c, * mach-o-arm.c, * mach-o-i386.c, * mach-o-target.c, * mach-o-x86-64.c, * mach-o.c, * mach-o.h, * merge.c, * mipsbsd.c, * mmo.c, * netbsd.h, * netbsd-core.c, * newsos3.c, * nlm-target.h, * nlm32-ppc.c, * nlm32-sparc.c, * nlmcode.h, * ns32k.h, * ns32knetbsd.c, * oasys.c, * opncls.c, * pc532-mach.c, * pdp11.c, * pe-arm.c, * pe-i386.c, * pe-mcore.c, * pe-mips.c, * pe-x86_64.c, * peXXigen.c, * pef.c, * pef.h, * pei-arm.c, * pei-i386.c, * pei-mcore.c, * pei-x86_64.c, * peicode.h, * plugin.c, * ppcboot.c, * ptrace-core.c, * reloc.c, * riscix.c, * rs6000-core.c, * section.c, * som.c, * som.h, * sparclinux.c, * sparcnetbsd.c, * srec.c, * stabs.c, * sunos.c, * syms.c, * targets.c, * tekhex.c, * trad-core.c, * vax1knetbsd.c, * vaxnetbsd.c, * verilog.c, * versados.c, * vms-alpha.c, * vms-lib.c, * vms-misc.c, * wasm-module.c, * wasm-module.h, * xcofflink.c, * xsym.c, * xsym.h: Whitespace fixes. * bfd-in2.h, * libbfd.h, * libcoff.h: Regenerate.

2015-08-18Add output_type to bfd_link_infoH.J. Lu
The "shared" field in bfd_link_info is set for both DSO and and PIE. There are separate fields for executable and relocatable outputs. This patch adds an "output_type" field: enum output_type { type_unknown = 0, type_executable, type_dll, type_relocatable }; and a "pic" field to bfd_link_info to replace shared, executable and relocatable fields so that we can use the "output_type" field to check for output type and the "pic" field check if output is PIC. Macros, bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic and bfd_link_pie, are provided to check for output features. bfd/ * bfd/aoutx.h: Replace shared, executable, relocatable and pie fields with bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic and bfd_link_pie. * bfd/bout.c: Likewise. * bfd/coff-alpha.c: Likewise. * bfd/coff-arm.c: Likewise. * bfd/coff-i386.c: Likewise. * bfd/coff-i960.c: Likewise. * bfd/coff-m68k.c: Likewise. * bfd/coff-mcore.c: Likewise. * bfd/coff-mips.c: Likewise. * bfd/coff-ppc.c: Likewise. * bfd/coff-rs6000.c: Likewise. * bfd/coff-sh.c: Likewise. * bfd/coff-tic80.c: Likewise. * bfd/coff-x86_64.c: Likewise. * bfd/coff64-rs6000.c: Likewise. * bfd/coffgen.c: Likewise. * bfd/cofflink.c: Likewise. * bfd/ecoff.c: Likewise. * bfd/ecofflink.c: Likewise. * bfd/elf-bfd.h: Likewise. * bfd/elf-eh-frame.c: Likewise. * bfd/elf-ifunc.c: Likewise. * bfd/elf-m10200.c: Likewise. * bfd/elf-m10300.c: Likewise. * bfd/elf-s390-common.c: Likewise. * bfd/elf-vxworks.c: Likewise. * bfd/elf.c: Likewise. * bfd/elf32-arm.c: Likewise. * bfd/elf32-avr.c: Likewise. * bfd/elf32-bfin.c: Likewise. * bfd/elf32-cr16.c: Likewise. * bfd/elf32-cr16c.c: Likewise. * bfd/elf32-cris.c: Likewise. * bfd/elf32-crx.c: Likewise. * bfd/elf32-d10v.c: Likewise. * bfd/elf32-dlx.c: Likewise. * bfd/elf32-epiphany.c: Likewise. * bfd/elf32-fr30.c: Likewise. * bfd/elf32-frv.c: Likewise. * bfd/elf32-ft32.c: Likewise. * bfd/elf32-h8300.c: Likewise. * bfd/elf32-hppa.c: Likewise. * bfd/elf32-i370.c: Likewise. * bfd/elf32-i386.c: Likewise. * bfd/elf32-i860.c: Likewise. * bfd/elf32-ip2k.c: Likewise. * bfd/elf32-iq2000.c: Likewise. * bfd/elf32-lm32.c: Likewise. * bfd/elf32-m32c.c: Likewise. * bfd/elf32-m32r.c: Likewise. * bfd/elf32-m68hc11.c: Likewise. * bfd/elf32-m68hc1x.c: Likewise. * bfd/elf32-m68k.c: Likewise. * bfd/elf32-mcore.c: Likewise. * bfd/elf32-mep.c: Likewise. * bfd/elf32-metag.c: Likewise. * bfd/elf32-microblaze.c: Likewise. * bfd/elf32-moxie.c: Likewise. * bfd/elf32-msp430.c: Likewise. * bfd/elf32-mt.c: Likewise. * bfd/elf32-nds32.c: Likewise. * bfd/elf32-nios2.c: Likewise. * bfd/elf32-or1k.c: Likewise. * bfd/elf32-ppc.c: Likewise. * bfd/elf32-rl78.c: Likewise. * bfd/elf32-rx.c: Likewise. * bfd/elf32-s390.c: Likewise. * bfd/elf32-score.c: Likewise. * bfd/elf32-score7.c: Likewise. * bfd/elf32-sh-symbian.c: Likewise. * bfd/elf32-sh.c: Likewise. * bfd/elf32-sh64.c: Likewise. * bfd/elf32-spu.c: Likewise. * bfd/elf32-tic6x.c: Likewise. * bfd/elf32-tilepro.c: Likewise. * bfd/elf32-v850.c: Likewise. * bfd/elf32-vax.c: Likewise. * bfd/elf32-visium.c: Likewise. * bfd/elf32-xc16x.c: Likewise. * bfd/elf32-xstormy16.c: Likewise. * bfd/elf32-xtensa.c: Likewise. * bfd/elf64-alpha.c: Likewise. * bfd/elf64-hppa.c: Likewise. * bfd/elf64-ia64-vms.c: Likewise. * bfd/elf64-mmix.c: Likewise. * bfd/elf64-ppc.c: Likewise. * bfd/elf64-s390.c: Likewise. * bfd/elf64-sh64.c: Likewise. * bfd/elf64-x86-64.c: Likewise. * bfd/elflink.c: Likewise. * bfd/elfnn-aarch64.c: Likewise. * bfd/elfnn-ia64.c: Likewise. * bfd/elfxx-mips.c: Likewise. * bfd/elfxx-sparc.c: Likewise. * bfd/elfxx-tilegx.c: Likewise. * bfd/i386linux.c: Likewise. * bfd/linker.c: Likewise. * bfd/m68klinux.c: Likewise. * bfd/pdp11.c: Likewise. * bfd/pe-mips.c: Likewise. * bfd/peXXigen.c: Likewise. * bfd/reloc.c: Likewise. * bfd/reloc16.c: Likewise. * bfd/sparclinux.c: Likewise. * bfd/sunos.c: Likewise. * bfd/vms-alpha.c: Likewise. * bfd/xcofflink.c: Likewise. include/ * include/bfdlink.h (output_type): New enum.

2014-11-11ld -r abort in _bfd_elf_write_section_eh_frameAlan Modra
Turning on .eh_frame processing for ld -r resulted in systemtap tickling a ld bug. Triggered by the zero terminator not being added to .eh_frame in a separate file as it usually is (crtend.o), but instead being present in the last .eh_frame section along with CIEs and FDEs.

2014-10-04Discard zero address range eh_frame FDEsAlan Modra
These are useless because they can't match any address. In fact, worse than useless because the .eh_frame_hdr lookup table matching addresses to FDEs does not contain information about the FDE range. The table is sorted by address; Range is inferred by the address delta from one entry to the next. So if a zero address range FDE is followed by a normal non-zero range FDE for the same address, everything is good. However, the qsort could just as easily sort the FDEs in the other order, in which case the normal FDE would effectively be seen to have a zero range. bfd/ PR 17447 * elf-bfd.h (struct eh_cie_fde): Comment re NULL u.fde.cie_inf. * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Mark zero address range FDEs for discarding.

2014-09-12Test for overflow in eh_frame_hdr entries and for overlapping FDEsAlan Modra
With larger binaries on 64-bit systems, or indeed just binaries that have a large gap between text and data, it is possible for the .eh_frame_hdr lookup table entry values to overflow a signed 32-bit relative offset. It is also a requirement for the glibc FDE lookup code that only one FDE claim to cover any given address. * elf-bfd.h (struct eh_frame_array_ent): Add "range". * elf-eh-frame.c (_bfd_elf_write_section_eh_frame): Stash address range of FDEs to hdr_info->array.

2014-08-22Delete redundant struct cie fieldAlan Modra
cie->output_sec is used to when merging CIEs to ensure that only CIEs from the same output section are merged. I noticed an assignment to this field in _bfd_elf_parse_eh_frame, and thought "That's wrong, output_section isn't set properly when _bfd_elf_parse_eh_frame is called from gc-sections code". It turns out that this assignment is premature, and in fact a dead store. find_merged_cie overwrites with the correct value before the field is ever used. On looking a little more it becomes apparent that cie->cie_inf.u.cie.u.sec->output_section holds the same value, so cie->output_sec is redundant. * elf-eh-frame.c (struct cie): Delete "output_sec" field. (cie_eq, cie_compute_hash): Use output_section from cie_inf instead.
2014-08-22Index PowerPC64 linker generated .eh_frame in .eh_frame_hdrAlan Modra
I noticed recently that .eh_frame FDEs generated by the linker for call stubs and .glink weren't being indexed in .eh_frame_hdr, due to bfd_elf_discard_info being run before the linker generated .eh_frame sections were available for parsing. This patch moves code around in elf64-ppc.c and ppc64elf.em to avoid that problem. Another problem fixed here is that --gc-sections parses .eh_frame early, and the existing machinery allows only one go at parsing the .eh_frame sections. That resulted in the linker generated .eh_frame CIEs not being merged and no .eh_frame_hdr index entries for those FDEs. It turns out that all the info from parsing .eh_frame is attached to the section, so order of parsing isn't important, and after parsing sec_info_type being set will prevent a section being parsed again. At least, when parsing doesn't hit an error. So there isn't really any need for "parsed_eh_frame". "merge_cies" is also redundant, which means _bfd_elf_{begin,end}_eh_frame_parsing can also disappear. bfd/ * elf-bfd.h (struct eh_frame_hdr_info): Delete merge_cies and parsed_eh_frames.
