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.

X86 disassembler checks data and address size prefixes when displaying instruction mnemonic and operands.

2014-04-15[AArch64] Fix off by one error in instruction relaxation mask.Marcus Shawcroft2-1/+6
The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to ensure that destination register in a relaxed ldr instruction is always X0. The mask has an off by one error resulting in the most significant bit of the destination register being retained in the relaxed instruction. The issue generally appears when the compiler emits TLS accesses code under high register pressure resulting in a broken code sequence.

2014-04-09ppc476 icache workaround fix for bctrAlan Modra2-0/+46
I got the ppc476 workaround wrong. bctr (and bctrl) as the last instruction in a page can hit the icache bug if the preceding mtctr insn is close by, and the destination is in the first few instructions on the next page. This scenario can occur with code generated by gcc to implement switch statements, or in code generated to call by function pointer. To prevent the bctr problem it is also necessary to remove other instructions that otherwise would be safe. bfd/ * elf32-ppc.c (ppc_elf_relocate_section): Remove bctr from list of safe ppc476 insns at end of page.

2014-04-04Document optional comma in linker script.Cary Coutant2-2/+13
The linker script documentation does not mention the optional comma that may follow an output section command or an overlay command. In some cases, where a fill expression is used, and the next output section command begins with an operator (e.g., "/DISCARD/"), the comma may be required to separate the two commands. Currently, GNU ld doesn't require the comma, but gold does. ld/ PR gold/16804 * ld.texinfo: Document optional comma following output section command and overlay command.

When aligning input sections, we are supposed to take the fill pattern from a FILL statement, if there is one in the output section statement. ld/ * ldlang.c (lang_size_sections_1 <lang_input_section_enum>): Use current "fill", not "output_section_statement->fill". ld/testsuite/ * ld-scripts/fill.d, * ld-scripts/fill.t, * ld-scripts/fill_0.s, * ld-scripts/fill_1.s, * ld-scripts/fill_2.s: New test. * ld-scripts/data.exp: Run it.
2014-03-31This is a fix for PR ld/16744 which showed that an object file linked with ↵Nick Clifton2-1/+21
-r and -z [no]execstack would not honour the [no]execstack. Fully linked binaries use a special segment to indicate the state of the stack, but relocatable object files only have sections, and .note.GNU-stack was not being created. * emultempl/elf32.em (_after_open): Create a .note.GNU-stack section when performing a relocatable link with -z [no]execstack specified.

2014-03-27Referencing a function's address on PowerPC64 ELFv2Alan Modra9-0/+68
ELFv2 needs to create plt entries in a non-PIC executable for an address reference to a function defined in a shared object. It's possible that an object file has no features that distinguish it as ELFv1 or ELFv2, eg. an object only containing data. Such files need to be handled like those that are known to be ELFv2. However, this unnecessarily creates plt entries for the analogous ELFv1 case, so arrange to set output abi version earlier, and use the output abi version to further distinguish ambiguous input files. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly needed plt entries when taking the address of functions for abiversion == 0 (ie. unknown) as well as abiversion == 2.

2014-03-25bfd/elfnn-aarch64.c: Fix calculation of DT_RELASZWill Newton4-0/+35
The current code subtracts the size of the output section containing relplt from RELASZ. In some cases this will be the same output section as the dynamic relocs causing a value of zero to be output. Calculating the size from input sections seems to make more sense. bfd/ChangeLog: 2014-03-25 Will Newton <will.newton@linaro.org> * elfnn-aarch64.c (elfNN_aarch64_finish_dynamic_sections): Set value of DT_PLTRELSZ and DT_RELASZ based on the size of input sections rather than output sections. ld/testsuite/ChangeLog: 2014-03-25 Will Newton <will.newton@linaro.org> * ld-aarch64/aarch64-elf.exp: Add relasz dump test. * ld-aarch64/relasz.d: New file. * ld-aarch64/relasz.s: Likewise.
