2014-07-17or1k: increase linux TEXT_START_ADDR to 0x2000Stefan Kristiansson2-0/+6
Override the default value of 0x0000 defined in TEXT_START_ADDR to avoid linux executables to be mapped at zero page. ld/ * emulparams/elf32or1k_linux.sh (TEXT_START_ADDR): Increase from 0x0 to first page boundary at 0x2000.
2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu9-5/+218
Relocations against .got.plt section may not be in the same order as entries in PLT section. It is incorrect to assume that the Ith reloction index against .got.plt section always maps to the (I + 1)th entry in PLT section. This patch matches the .got.plt relocation offset/index in PLT entry against the index in .got.plt relocation table. It only checks R_*_JUMP_SLOT and R_*_IRELATIVE relocations. It ignores R_*_TLS_DESC and R_*_TLSDESC relocations since they have different PLT entries. bfd/ PR binutils/17154 * elf32-i386.c (elf_i386_plt_sym_val): Only match R_*_JUMP_SLOT and R_*_IRELATIVE relocation offset with PLT entry. * elf64-x86-64.c (elf_x86_64_plt_sym_val): Likewise.

2014-07-10Fix xtensa ld segfault when linking linux modulesMax Filippov2-1/+7
is_inconsistent_linkonce_section makes an assumption that section name that starts with ".gnu.linkonce.prop." has one more dot in its suffix. However gas generates such section name by insertion of "prop." right after ".gnu.linkonce." part of the name of the original section. So, for section named ".gnu.linkonce.this_module" corresponding property section name does not satisfy the assumption. Such section names are common in linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment for the first section frag on xtensa", that makes gas produce property section for each section that has ".align" directive in it. Use suffix that immediately follows ".gnu.linkonce.prop." when there are no more dots following it. 2014-07-10 Max Filippov <jcmvbkbc@gmail.com> ld/ * emultempl/xtensaelf.em (is_inconsistent_linkonce_section): correctly handle missing dot in section name after ".gnu.linkonce.prop.".

2014-07-08Copy st_other for linker script symbol assignmentsAlan Modra4-0/+51
This fixes a problem seen on powerpc64le ELFv2 when creating a function symbol alias with ld --defsym. st_other needs to be copied from the source symbol to the alias in order to set up the local entry offset for the alias.

2014-07-08Run ar with --plugin for LTO 11 testAlan Modra2-1/+20
Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have no normal symbols, except things like __gnu_lto_slim. These useless symbols are the ones put into the archive index, and of course nothing references them so no objects are extracted by the linker. Running ar with --plugin changes ar behaviour to put the lto symbols into the archive index. PR 17112 * ld-plugin/lto.exp: When building liblti-11.a, pass --plugin path_to_gcc/liblto_plugin.so to ar.

2014-07-07Ensure ld testsuite gcc -B options precede $CC -B optionsAlan Modra5-108/+93
Various ld-elf/shared.exp and ld-plugin/lto.exp tests simply appended the testsuite -B options intended to force gcc use the linker under test. This fails if $CC itself has -B options, as when setting CC to run gcc out of a build directory.

2014-07-01Don't include sys/param.hAlan Modra3-23/+8
sys/param.h on recent versions of powerpc glibc ends up including asm/elf.h via asm/sigcontex.h. asm/elf.h defines R_PPC_* and R_PPC64_* macros, which clash with our include/elf/ppc.h and include/elf/ppc64.h.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra3-19/+7
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.

2014-06-05Make it easy to make --disable-werror the default for both binutils and gdbJoel Brobecker4-6/+17
The goal of this patch is to provide an easy way to make --disable-werror the default when building binutils, or the parts of binutils that need to get built when building GDB. In development mode, we want to continue making -Werror the default with GCC. But, when making releases, I think we want to make it as easy as possible for regular users to successfully build from sources. GDB already has this kind of feature to turn -Werror as well as the use of the libmcheck library. As GDB Release Manager, I take advantage of it to turn those off after having cut the branch. I'd like to be able to do the same for the binutils bits. And perhaps Tristan will want to do the same for his releases too (not sure, binutils builders might be a little savvier than GDB builders). This patch introduces a new file, called development.sh, which just sets a variable called $development. In our development branches (Eg. "master"), it's set to true. But setting it to false would allow us to change the default behavior of various development-related features to be turned off; in this case, it turns off the use of -Werror by default (use --enable-werror to turn it back on). bfd/ChangeLog: * development.sh: New file. * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh. Make -Werror the default with GCC only if DEVELOPMENT is true. * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add $(srcdir)/development.sh. * Makefile.in, configure: Regenerate. binutils/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gas/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gold/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): New. * Makefile.in, configure: Regenerate. gprof/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. ld/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. opcodes/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gdb/ChangeLog: * development.sh: Delete. * Makefile.in (config.status): Adjust dependency on development.sh. * configure.ac: Adjust development.sh source call. * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: Adjust development.sh source call. * Makefile.in (config.status): Adjust dependency on development.sh. * configure: Regenerate. Tested on x86_64-linux by building two ways: One with DEVELOPMENT set to true, and one with DEVELOPMENT set to false. In the first case, I could see the use of -Werror, while it disappeared in the second case.

Power8 fuses addis,addi and addis,ld sequences when the target of the addis is the same as the addi/ld. Thus addis r12,r2,xxx@ha addi r12,r12,xxx@l / ld r12,xxx@l(r12) is faster than addis r11,r2,xxx@ha addi r12,r11,xxx@l / ld r12,xxx@l(r11) So use the form that allows fusion in plt call and branch stubs. bfd/ * elf64-ppc.c (ADDIS_R12_R2): Define.

2014-05-20Rewrite ppc32 backend .sdata and .sdata2 handlingAlan Modra4-11/+17
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections. PR 16952 bfd/ * elf32-ppc.c (ppc_elf_create_linker_section): Move earlier. Remove redundant setting of htab->elf.dynobj. Don't align. Define .sdata symbols using _bfd_elf_define_linkage_sym.
