The idea of this change is to make -t output useful for users wanting to package all the object files involved in linking for a bug report. Something like the following should do the trick. gcc hello.c -save-temps -Wl,-t | xargs realpath | sort | uniq > files tar cJf test.tar.xz `cat files` * ldlang.c (load_symbols): When -t, print file names for script files and archives. * ldmain.c (trace_files): Make an int. (add_archive_element): Print archive elements only with multiple -t options, or when archive is thin. * ldmain.h (trace_files): Update. * ldmisc.c (vfinfo): Don't print both original path and path in sysroot. * lexsup.c (parse_args <t>): Increment trace_files.

Andrew Sadek <andrew.sadek.se@gmail.com> A new implemented feature in GCC Microblaze that allows Position Independent Code to run using Data Text Relative addressing instead of using Global Offset Table. Its aim was to make 'PIC' more efficient and flexible as elf size excess performance overhead were noticed when using GOT due to the indirect addressing. include/ChangeLog: * bfdlink.h (Add flag): Add new flag @ 'bfd_link_info' struct. * elf/microblaze.h (Add 3 new relocations): R_MICROBLAZE_TEXTPCREL_64, R_MICROBLAZE_TEXTREL_64 and R_MICROBLAZE_TEXTREL_32_LO for relax function. bfd/ChangeLog: * bfd/reloc.c (2 new BFD relocations): BFD_RELOC_MICROBLAZE_64_TEXTPCREL & BFD_RELOC_MICROBLAZE_64_TEXTPCREL * bfd/bfd-in2.h: Regenerate * bfd/libbfd.h: Regenerate * bfd/elf32-microblaze.c (Handle new relocs): define 'HOWTO' of 3 new relocs and handle them in both relocate and relax functions.

This patch standardizes messages in ld, to better conform to the GNU coding standard. Besides issues of capitalization and full-stops, I've - Split up help messages for target options, so that adding a new option does not mean loss of translation for all the others. - Embedded tabs have been removed, since a user might have tab stops set at other than 8 char intervals. - Added missing program name (%P). ld isn't the compiler. - Put %F and %X first (and removed %X if %F was present). These can go anywhere, but look silly in the m%Fiddle of a message, and choosing "%P%F:" in some messages but "%F%P:" in others leads to the likelihood of duplication in ld.pot. Besides, the colon belongs with %P. * emulparams/call_nop.sh, * emulparams/cet.sh, * emulparams/elf32mcore.sh, * emultempl/aarch64elf.em * emultempl/aix.em, * emultempl/alphaelf.em, * emultempl/armcoff.em, * emultempl/armelf.em, * emultempl/avrelf.em, * emultempl/beos.em, * emultempl/bfin.em, * emultempl/cr16elf.em, * emultempl/elf32.em, * emultempl/elf-generic.em, * emultempl/hppaelf.em, * emultempl/linux.em, * emultempl/lnk960.em, * emultempl/m68hc1xelf.em, * emultempl/m68kcoff.em, * emultempl/m68kelf.em, * emultempl/metagelf.em, * emultempl/mipself.em, * emultempl/mmix-elfnmmo.em, * emultempl/mmo.em, * emultempl/msp430.em, * emultempl/nds32elf.em, * emultempl/nios2elf.em, * emultempl/pe.em, * emultempl/pep.em, * emultempl/ppc32elf.em, * emultempl/ppc64elf.em, * emultempl/scoreelf.em, * emultempl/sh64elf.em, * emultempl/spuelf.em, * emultempl/sunos.em, * emultempl/tic6xdsbt.em, * emultempl/ticoff.em, * emultempl/v850elf.em, * emultempl/vms.em, * emultempl/vxworks.em, * emultempl/xtensaelf.em, * ldcref.c, * ldctor.c, * ldexp.c, * ldfile.c, * ldgram.y, * ldlang.c, * ldmain.c, * ldmisc.c, * ldwrite.c, * lexsup.c, * mri.c, * pe-dll.c, * plugin.c: Standardize error/warning messages. * testsuite/ld-arc/jli-overflow.err, * testsuite/ld-arm/cmse-implib-errors.out, * testsuite/ld-arm/cmse-new-earlier-later-implib.out, * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out, * testsuite/ld-arm/cmse-new-wrong-implib.out, * testsuite/ld-arm/cmse-veneers-no-gnu_sgstubs.out, * testsuite/ld-arm/cmse-veneers-wrong-entryfct.out, * testsuite/ld-arm/vxworks1-static.d, * testsuite/ld-cris/tls-err-20x.d, * testsuite/ld-cris/tls-err-29.d, * testsuite/ld-cris/tls-err-31.d, * testsuite/ld-cris/tls-err-33.d, * testsuite/ld-cris/tls-err-35.d, * testsuite/ld-cris/tls-err-37.d, * testsuite/ld-cris/tls-err-39.d, * testsuite/ld-cris/tls-err-41.d, * testsuite/ld-cris/tls-err-43.d, * testsuite/ld-cris/tls-err-45.d, * testsuite/ld-cris/tls-err-47.d, * testsuite/ld-cris/tls-err-49.d, * testsuite/ld-cris/tls-err-51.d, * testsuite/ld-cris/tls-err-67.d, * testsuite/ld-elf/dwarf2.err, * testsuite/ld-elf/dwarf3.err, * testsuite/ld-elf/orphan-5.l, * testsuite/ld-elf/orphan-6.l, * testsuite/ld-i386/vxworks1-static.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips.d, * testsuite/ld-mips-elf/bal-jalx-pic-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic.d, * testsuite/ld-mips-elf/jal-global-overflow-1.d, * testsuite/ld-mips-elf/jal-local-overflow-1.d, * testsuite/ld-mips-elf/mode-change-error-1.d, * testsuite/ld-mips-elf/unaligned-branch-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-r6-2.d, * testsuite/ld-mips-elf/unaligned-branch.d, * testsuite/ld-mips-elf/unaligned-jalx-1.d, * testsuite/ld-mips-elf/unaligned-jalx-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jump-micromips.d, * testsuite/ld-mips-elf/unaligned-jump-mips16.d, * testsuite/ld-mips-elf/unaligned-jump.d, * testsuite/ld-mips-elf/unaligned-ldpc-1.d, * testsuite/ld-mips-elf/unaligned-lwpc-1.d, * testsuite/ld-mips-elf/undefined.d, * testsuite/ld-mips-elf/vxworks1-static.d, * testsuite/ld-mmix/bpo-20.d, * testsuite/ld-mmix/bpo-20m.d, * testsuite/ld-mmix/bpo-7.d, * testsuite/ld-mmix/bpo-7m.d, * testsuite/ld-mmix/bpo-8.d, * testsuite/ld-mmix/bpo-8m.d, * testsuite/ld-mmix/greg-17.d, * testsuite/ld-mmix/greg-18.d, * testsuite/ld-mmix/greg-8.d, * testsuite/ld-mmix/greg-9.d, * testsuite/ld-plugin/plugin-14.d, * testsuite/ld-plugin/plugin-15.d, * testsuite/ld-plugin/plugin-16.d, * testsuite/ld-plugin/plugin-20.d, * testsuite/ld-plugin/plugin-21.d, * testsuite/ld-plugin/plugin-22.d, * testsuite/ld-plugin/plugin-23.d, * testsuite/ld-plugin/plugin-6.d, * testsuite/ld-plugin/plugin-7.d, * testsuite/ld-plugin/plugin-8.d, * testsuite/ld-powerpc/aix-weak-3-32.d, * testsuite/ld-powerpc/aix-weak-3-64.d, * testsuite/ld-powerpc/vxworks1-static.d, * testsuite/ld-sh/vxworks1-static.d, * testsuite/ld-sparc/vxworks1-static.d, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-x86-64/pie1.d: Update for changed errors and warnings. * testsuite/ld-elf/warn1.d, * testsuite/ld-elf/warn2.d: Correct regex.

2017-08-06Treat common symbol as undefined for --no-define-commonH.J. Lu1-1/+1
When --no-define-common is used to build shared library, treat common symbol as undefined so that common symbols that are referenced from a shared library to be assigned addresses only in the main program. This eliminates the unused duplicate space in the shared library, and also prevents any possible confusion over resolving to the wrong duplicate when there are many dynamic modules with specialized search paths for runtime symbol resolution. --no-define-common is only allowed when building a shared library. bfd/ PR ld/21903: * elflink.c (elf_link_add_object_symbols): Treat common symbol as undefined for --no-define-common. include/ PR ld/21903: * bfdlink.h (bfd_link_info): Add inhibit_common_definition. ld/ PR ld/21903: * ld.h (command_line): Remove inhibit_common_definition. * ldgram.y: Replace command_line.inhibit_common_definition with link_info.inhibit_common_definition. * ldlang.c (lang_common): Likewise. * lexsup.c (parse_args): Likewise. * ldmain.c (main): Only allow --no-define-common with -shared. * testsuite/ld-elf/pr21903.s: New file. * testsuite/ld-elf/pr21903a.d: Likewise. * testsuite/ld-elf/pr21903b.d: Likewise. * testsuite/ld-elf/pr21903c.d: Likewise. * testsuite/ld-elf/pr21903d.d: Likewise. * testsuite/ld-elf/pr21903e.d: Likewise.

2017-06-06ld: Allow section groups to be resolved as part of a relocatable linkAndrew Burgess1-0/+6
This commit adds a new linker feature: the ability to resolve section groups as part of a relocatable link. Currently section groups are automatically resolved when performing a final link, and are carried through when performing a relocatable link. By carried through this means that one copy of each section group (from all the copies that might be found in all the input files) is placed into the output file. Sections that are part of a section group will not match input section specifiers within a linker script and are forcibly kept as separate sections. There is a slight resemblance between section groups and common section. Like section groups, common sections are carried through when performing a relocatable link, and resolved (allocated actual space) only at final link time. However, with common sections there is an ability to force the linker to allocate space for the common sections when performing a relocatable link, there's currently no such ability for section groups. This commit adds such a mechanism. This new facility can be accessed in two ways, first there's a command line switch --force-group-allocation, second, there's a new linker script command FORCE_GROUP_ALLOCATION. If one of these is used when performing a relocatable link then the linker will resolve the section groups as though it were performing a final link, the section group will be deleted, and the members of the group will be placed like normal input sections. If there are multiple copies of the group (from multiple input files) then only one copy of the group members will be placed, the duplicate copies will be discarded. Unlike common sections that have the --no-define-common command line flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no way to prevent group resolution during a final link, this is because the ELF gABI specifically prohibits the presence of SHT_GROUP sections in a fully linked executable. However, the code as written should make adding such a feature trivial, setting the new resolve_section_groups flag to false during a final link should work as you'd expect. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Don't initially mark SEC_GROUP sections as SEC_EXCLUDE. (bfd_elf_set_group_contents): Replace use of abort with an assert. (assign_section_numbers): Use resolve_section_groups flag instead of relocatable link type.

2016-02-26Properly implement STT_COMMONH.J. Lu1-0/+4
The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default. Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF common symbols. bfd/ PR ld/19645 * bfd.c (bfd): Change flags to 20 bits. (BFD_CONVERT_ELF_COMMON): New.

2015-09-04ld: Extend options for altering orphan handling behaviour.Andrew Burgess1-10/+17
Replace the options --warn-orphan and --no-warn-orphan with a single option --orphan-handling=MODE, where mode can be place, warn, error, and discard. Mode 'place' is the default, and is the current behaviour, placing the orphan section into a suitable output section. Mode 'warn' is the same as '--warn-orphan'. The orphan is also placed using the same algorithm as for 'place'. Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'. Mode 'discard' assigns all output sections to the /DISCARD/ section. ld/ChangeLog: * ld.h (enum orphan_handling_enum): New.

2015-08-18Add output_type to bfd_link_infoH.J. Lu1-19/+27
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.

2015-08-04ld: Add '--require-defined' command line option.Andrew Burgess1-0/+6
Add a new command line option '--require-defined' to the linker. This option operates identically to the '--undefined' option, except that if the symbol is not defined in the final output file then the linker will exit with an error. When making use of --gc-section, or just when trying to pull in parts of a library, it is not uncommon for a user to use the '--undefined' command line option to specify a symbol that the user then expects to be defined by one of the object files supplied to the link. However, if for any reason the symbol is not satisfied by an object provided to the link the user will be left with an undefined symbol in the output file, instead of a defined symbol. In some cases the above behaviour is what the user wants, in other cases though we can do better. The '--require-defined' option tries to fill this gap. The symbol passed to the '--require-defined' option is treated exactly as if the symbol was passed to '--undefined', however, before the linker exits a check is made that all symbols passed to '--require-defined' are actually defined, if any are not then the link will fail with an error. ld/ChangeLog: * ld.texinfo (Options): Document --require-defined option. * ldlang.c (struct require_defined_symbol): New structure.
