2015-12-10ld: Fix LTO for MinGW targetsKwok Cheung Yeung1-2/+4
When creating a dummy BFD for an IR file, the output BFD is used as a template for the new BFD, when it needs to be the input BFD passed into the function when not dealing with a BFD plugin. On most targets this is not an issue as the input and output formats are the same anyway, but on MinGW targets, there are two variant formats used (pe-i386/pe-x86-64 and pei-i386/pei-x86-64) which are similar but not interchangeable here. PR ld/18199 * plugin.c (plugin_get_ir_dummy_bfd): Use srctemplate as the template when calling bfd_create if it does not use the BFD plugin target vector.

2015-08-18Add output_type to bfd_link_infoH.J. Lu1-5/+5
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.

2015-02-14PR ld/17973 LTO file symsAlan Modra1-4/+12
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.

2015-02-11Merge linker plugin handling into BFD plugin supportH.J. Lu1-32/+73
Linker plugin_maybe_claim is the interface of linker plugin support. This patch extracts linker plugin_maybe_claim into plugin_object_p and makes it available to BFD via a new function: void register_ld_plugin_object_p (const bfd_target *(*) (bfd *)); bfd_plugin_object_p calls plugin_object_p registered by linker first. It adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim to retrieve it later. bfd/ PR ld/17878 * bfd.c (bfd_plugin_format): New.

2015-02-05Add plugin_input_file_tH.J. Lu1-16/+105
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.
