Add output_type to bfd_link_info 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.

/* Add all the symbols from an object file to the hash table.
XCOFF is a weird format. A normal XCOFF .o files will have three
COFF sections--.text, .data, and .bss--but each COFF section will
contain many csects. These csects are described in the symbol
table. From the linker's point of view, each csect must be
considered a section in its own right. For example, a TOC entry is
handled as a small XMC_TC csect. The linker must be able to merge
different TOC entries together, which means that it must be able to
extract the XMC_TC csects from the .data section of the input .o
file.
From the point of view of our linker, this is, of course, a hideous
nightmare. We cope by actually creating sections for each csect,
and discarding the original sections. We then have to handle the
relocation entries carefully, since the only way to tell which
csect they belong to is to examine the address. */

a symbol is defined multiple times, and the only
references are from the same object file, the AIX linker
appears to permit it. It does not merge the different
definitions, but handles them independently. On the
other hand, if there is a reference, the linker reports
an error.
This matters because the AIX <net/net_globals.h> header
file actually defines an initialized array, so we have to
actually permit that to work.
Just to make matters even more confusing, the AIX linker
appears to permit multiple symbol definitions whenever
the second definition is in an archive rather than an
object file. This may be a consequence of the manner in
which it handles archives: I think it may load the entire
archive in as separate csects, and then let garbage
collection discard symbols.
We also have to handle the case of statically linking a
shared object, which will cause symbol redefinitions,
although this is an easier case to detect. */

Fix LTO vs. COFF archives Avoid scan of symbols on objects in coff archives since we don't need to do anything special with common symbols. The scan is quite useless, and breaks LTO due to slim LTO objects not having symbols available until after the plugin has claimed them. Instead we can add objects based on their archive symbol map. Also, rip out the archive symbol hash table used by the generic linker. Using a hash breaks one feature of unix archive linking; The first object file in an archive defining any given symbol should be the object extracted to satisfy that symbol. What's more a hash isn't much faster except in pathological cases where object file ordering causes many scans of the archive. See the comment which I'm removing from elf_link_add_archive_symbols. Finally, tidy elflink.c archive handling a little.

Fix LTO vs. COFF archives Avoid scan of symbols on objects in coff archives since we don't need to do anything special with common symbols. The scan is quite useless, and breaks LTO due to slim LTO objects not having symbols available until after the plugin has claimed them. Instead we can add objects based on their archive symbol map. Also, rip out the archive symbol hash table used by the generic linker. Using a hash breaks one feature of unix archive linking; The first object file in an archive defining any given symbol should be the object extracted to satisfy that symbol. What's more a hash isn't much faster except in pathological cases where object file ordering causes many scans of the archive. See the comment which I'm removing from elf_link_add_archive_symbols.

providing a shared version of it. In particular, this solves
a bug involving the _savefNN set of functions. gcc will call
those functions without providing a slot to restore the TOC,
so it is essential that these functions be linked in directly

Add output_type to bfd_link_info 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.

Add output_type to bfd_link_info The "shared" field in bfd_link_info is set for both DSO and and PIE. There are separate fields for executable and relocatable outputs.

Fallout from recent bfd_reloc_outofrange changes Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from.. (bfd_get_section_limit): ..here. * reloc.c (bfd_perform_relocation): Correct bfd_reloc_outofrange check.

Add output_type to bfd_link_info 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.
