2015-08-18Add output_type to bfd_link_infoH.J. Lu51-229/+320
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.

2015-08-13Issue an error for read-only segment with dynamic IFUNC relocationsH.J. Lu7-0/+48
To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls __mprotect on the read-only segment with PROT_READ|PROT_WRITE before applying dynamic relocation. It leads to segfault when performing IFUNC relocations since the read-only segment has no execute permission. This patch changes x86 linker to issue an error for read-only segment with dynamic IFUNC relocations. Other backends with IFUNC support may need a similar change. bfd/ PR ld/18801 * elf32-i386.c (elf_i386_size_dynamic_sections): Issue an error for read-only segment with dynamic IFUNC relocations. * elf64-x86-64.c (elf_x86_64_size_dynamic_sections): Likewise. ld/testsuite/ PR ld/18801 * ld-i386/i386.exp: Run pr18801. * ld-x86-64/x86-64.exp: Likewise. * ld-i386/pr18801.d: New file. * ld-i386/pr18801.s: Likewise. * ld-x86-64/pr18801.d: Likewise. * ld-x86-64/pr18801.s: Likewise.

2015-08-12Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbolsH.J. Lu6-0/+50
Since the backend elf_add_symbol_hook isn't called on local symbols, the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols. This patch changes the x86 backends to set has_gnu_symbols if there are relocations against IFUNC symbols. Other backends with IFUNC support may need a similar change.

The hidden versioned symbol can only be merged with the versioned symbol with the same symbol version. _bfd_elf_merge_symbol should check the symbol version before merging the new hidden versioned symbol with the existing symbol. _bfd_elf_link_hash_copy_indirect can't copy any references to the hidden versioned symbol.

2015-08-04ld: map option for run_dump_test requires no program.Andrew Burgess2-0/+10
When using run_dump_test with the map option to compare the linker map file produced, no additional dump program should be required. A dump program can still be given if needed, but leaving it off will no longer produce an error. ld/testsuite/ChangeLog: * ld/ld-lib.exp (run_dump_test): When using the map option, no program is required.
2015-08-04ld: Add file based error/warning regexp for run_dump_test.Andrew Burgess2-17/+78
The run_dump_test mechanism supports options error and warning, which allow regexp to be specified within the test file, these regexp are matched against the stderr output from the linker. Similar dump test style functions for gas and gdb also support file based matching versions of these options; the patterns are placed into a file which the test driver then references. It is sometimes clearer, when the pattern to be matched spans multiple lines if the patterns can be placed into a separate file. This patch adds new options error_output and warning_output for the linker run_dump_test function. These new options take a filename parameter, this file is then used (with regexp_diff) to compare against the linker output. ld/testsuite/ChangeLog: * ld/ld-lib.exp (run_dump_test): Add error_output and warning_output options.
2015-08-04ld: Add '--require-defined' command line option.Andrew Burgess15-0/+209
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.

Commit 23283c1b changed the layout of some bss style sections on powerpc64, but neglected to add a page gap before the third PT_LOAD segment created by this reording.
