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.

The RELOCATE_SECTION function is called by the new ELF backend linker

to handle the relocations for a section.

The relocs are always passed as Rela structures; if the section

zero.

necessary, and (if using Rela relocs and generating a relocatable

output file) adjusting the reloc addend as necessary.

This function does not have to worry about setting the reloc

address or the reloc symbol index.

LOCAL_SYMS is a pointer to the swapped in local symbols.

LOCAL_SECTIONS is an array giving the section in the input file

corresponding to the st_shndx field of each local symbol.
|

The global hash table entry for the global symbols can be found
|

via elf_sym_hashes (input_bfd).

When generating relocatable output, this function must handle
|

STB_LOCAL/STT_SECTION symbols specially. The output symbol is

going to be the section symbol corresponding to the output

section, which means that the addend must be adjusted
