Increase the maximum page size to 64kB and align the TEXT_START_ADDR to a 64kB boundary.

2014-07-08Copy st_other for linker script symbol assignmentsAlan Modra5-13/+30
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. I decided to make this change in the generic ELF code rather than in elf64-ppc.c since it looks like other targets that use st_other bits might benefit too. bfd/ * elflink.c (_bfd_elf_copy_link_hash_symbol_type): Copy st_other bits from source to dest. * linker.c (_bfd_generic_copy_link_hash_symbol_type): Update comment. * targets.c (struct bfd_target <_bfd_copy_link_hash_symbol_type>): Likewise. * bfd-in2.h: Regenerate. ld/testsuite/ * ld-powerpc/defsym.s, * ld-powerpc/defsym.d: New test. * ld-powerpc/powerpc.exp: Run it.
2014-07-08Enable elf_backend_rela_normal for AArch64Jiong Wang2-9/+8
If we are generating non-relocatable object and --emit-relocs specified, aarch64 ld is actually generating wrong addend for rela entry when relocate against local symbol. for example, for simple testcase foo.c === const char * const a = "foo"; const char * foo () { return a; } bar.c === const char * const b = "bar"; const char * bar () { return b; } aarch64-none-linux-gnu-ld --emit-relocs -o x.o foo.o bar.o aarch64-none-linux-gnu-readelf -r x.o ...

R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0 while it should be: ... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0 ... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0 ...

R_AARCH64_ADD_ABS 0000000000400018 .rodata + 10 bfd generic code could actually handle this properly, but only when elf_backend_rela_normal set to '1'. this patch enable this and remove those target specific hack. bfd/ * elfnn-aarch64.c (elf_backend_rela_normal): Set to 1.

2014-07-01Add symbols for global entry stub, and report statsAlan Modra2-5/+42
The undefined function symbols (with non-zero value) on global entry stubs are discarded by objdump when disassembling, so give objdump another symbol to mark the stubs. Also fixes a couple of bugs: - entry_section was set to .opd for ELFv2, which meant a hard error rather than a warning when _start wasn't defined. - global entry stubs were not built if they were the only type of stub in an executable. bfd/ * elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry. (struct ppc_link_hash_table): Increase size of stub_count array. (build_global_entry_stubs): Emit symbol on global entry stub. (ppc64_elf_build_stubs): NULL check htab->brlt. Add global entry stub stats. ld/ * emultempl/ppc64elf.em (stub_added): Delete. (gld${EMULATION_NAME}_finish): Call ppc64_elf_build_stubs even when none of the usual stubs have been added. Only change entry_section for ELFv1.
2014-07-01Linker foreign output format support for PowerPC64 ELFv2Alan Modra2-19/+61
Makes the ld srec tests pass. Uses a horrible scan through symbols to find ELF fields for symbol definitions, but the generic linker doesn't offer anything better. Might be slow. Anyway, sane people will link to ELF output then objcopy to convert formats. * elf64-ppc.c (abiversion, set_abiversion): Move earlier. (ppc64_elf_branch_reloc): Adjust addend for ELFv2 local offset. (ppc64_elf_set_toc): Set ".TOC." symbol value when using generic linker. (ppc64_elf_relocate_section): Disable ELFv2 function entry optimisation when --traditional-format.

2014-06-24Don't strip section defining _SDA_BASE_Alan Modra2-3/+22
Prior to 93d1b056 _SDA_BASE_ used to be defined in a linker script output section. Now _SDA_BASE_ is defined in an input section that is subject to being stripped. If the section is stripped we don't output the symbol, which results in --emit-relocs trying to emit relocs with dangling references to _SDA_BASE_. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Arrange to keep .sdata/.sdata2 when _SDA_BASE_/_SDA2_BASE_ should be output for --emit-relocs.
