2015-08-18Add output_type to bfd_link_infoH.J. Lu1-8/+8
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.

2014-12-04Add _bfd_elf_ifunc_get_synthetic_symtabH.J. Lu1-0/+125
In i386 and x86-64 binaries with ifunc, relocations against .got.plt section may not be in the same order as entries in PLT section. This patch adds _bfd_elf_ifunc_get_synthetic_symtab. It takes a function pointer which returns an array of PLT entry symbol values. It calls the function pointer to get the PLT entry symbol value array indexed by relocation index, instead of calling plt_sym_val on each relocation index.

2013-04-15Check regular reference without non-GOT referenceH.J. Lu1-14/+11
non_got_ref may not be set when building shared library. We need to set non_got_ref if there are any non-PIC relocations. But we only did this when there were no PLT/GOT relocations. It failed when there is a PLT relocation. This checkin moves the non_got_ref check out. bfd/ 2013-04-15 H.J.
