Add "-z call-nop=PADDING" option to ld The ld linker can transform indirect call to a locally defined function, foo, via its GOT slot, to either "NOP call foo" or "call foo NOP" where NOP is a 1-byte NOP padding.

ld: Extend options for altering orphan handling behaviour. 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.

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.

ld: Add '--require-defined' command line option. 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.

* emulparams/elf64ppc.sh (GOT): Align.
Rewrite relro adjusting code The linker tries to put the end of the last section in the relro segment exactly on a page boundary, because the relro segment itself must end on a page boundary. If for any reason this can't be done, padding is inserted. Since the end of the relro segment is typically between .got and .got.plt, padding effectively increases the size of the GOT. This isn't nice for targets and code models with limited GOT addressing. The problem with the current code is that it doesn't cope very well with aligned sections in the relro segment. When making .got aligned to a 256 byte boundary for PowerPC64, I found that often the initial alignment attempt failed and the fallback attempt to be less than adequate. This is a particular problem for PowerPC64 since the distance between .got and .plt affects the size of plt call stubs, leading to "stubs don't match calculated size" errors. So this rewrite takes a direct approach to calculating a new relro base. Starting from the last section in the segment, we calculate where it must start to position its end on the boundary, or as near as possible considering alignment requirements. The new start then becomes the goal for the previous section to end, and so on for all sections. This of course ignores the possibility that user scripts will place . = ALIGN(xxx); in the relro segment, or provide section address expressions. In those cases we might fail, but the old code probably did too, and a fallback is provided. ld/ * ldexp.h (struct ldexp_control): Delete dataseg.min_base.

By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library.

PR ld/17973 LTO file syms LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

Add plugin_input_file_t This patchs adds plugin_input_file_t to implement get_input_file, get_view and release_input_file. The maximum memeory overhead per IR input file are about 40 bytes for plugin_input_file_t plus the memory to store input IR filename. According to http://gcc.gnu.org/wiki/whopr/driver RELEASE_INPUT_FILE: Function pointer to the linker interface that releases a file descriptor for a claimed input file. The plug-in library must call this interface for each file descriptor obtained by the "get input file" interface. It must release all such file descriptors before returning from the WPA phase. However, GCC plug-in library doesn't use the "get input file" interface. It processed the IR input in the claim file handler. Since the the file descriptor opened for the IR input was unused after the claim file handler returns and GCC plug-in library before GCC 5 doesn't call the RELEASE_INPUT_FILE function pointer, ld closed the file descriptor to avoid leaking file descriptor. But this approach doesn't work with other plug-in libraries which uses the "get input file", "get view" and "release input file" interfaces. To avoid file descriptor leak with GCC prior to GCC 5 and support other plug-in libraries at the same time, we close the file descriptor only if the input IR file is a bfd_object file. This scheme doesn't work when a plug-in library needs the file descriptor and its IR is stored in bfd_object file. PR ld/17878 * plugin.c: Include <errno.h>. (errno): New. Declare if needed.

ld: Don't evaluate unneeded PROVIDE expressions. When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined.
