2016-05-27MIPS/BFD: Fix section symbol name fetching in relocationMaciej W. Rozycki2-1/+7
Symbol table entries for section symbols are different between IRIX and traditional MIPS ELF targets in that IRIX entries have their `st_name' member pointing at the section's name in the string table section, while traditional entries have 0 there and the section header string table has to be referred via the relevant section header's `shn_name' member instead. This is chosen with the `elf_backend_name_local_section_symbols' backend and can be observed with `readelf -s' output for an IRIX object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 .text 2: 00000000 0 SECTION LOCAL DEFAULT 3 .data 3: 00000000 0 SECTION LOCAL DEFAULT 4 .bss 4: 00000000 0 SECTION LOCAL DEFAULT 5 .reginfo 5: 00000000 0 SECTION LOCAL DEFAULT 6 .MIPS.abiflags 6: 00000000 0 SECTION LOCAL DEFAULT 7 .pdr 7: 00000000 0 SECTION LOCAL DEFAULT 9 .gnu.attributes 8: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 9: 00004008 0 FUNC LOCAL DEFAULT 1 abar 10: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar and a corresponding traditional object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 2: 00000000 0 SECTION LOCAL DEFAULT 3 3: 00000000 0 SECTION LOCAL DEFAULT 4 4: 00004008 0 FUNC LOCAL DEFAULT 1 abar 5: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 6: 00000000 0 SECTION LOCAL DEFAULT 5 7: 00000000 0 SECTION LOCAL DEFAULT 6 8: 00000000 0 SECTION LOCAL DEFAULT 7 9: 00000000 0 SECTION LOCAL DEFAULT 9 10: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar respectively. Consequently the right way to retrieve a section symbol's name has to be chosen in `mips_elf_calculate_relocation' for the purpose of error reporting. Originally we produced symbol tables in the traditional object format only and we handled it correctly until it was lost in a rewrite with: commit 7403cb6305f5660fccc8869d3333a731102ae978 Author: Mark Mitchell <mark@codesourcery.com> Date: Wed Jun 30 20:13:43 1999 +0000 probably because of the extra pointer indirection added which made the same expression have a different meaning. With the addition of IRIX symbol table format with: commit 174fd7f9556183397625dbfa99ef68ecd325c74b Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Mon Feb 9 08:04:00 2004 +0000 the bug has been partially covered and now when a relocation error is triggered with an IRIX object the offending section symbol is correctly reported: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `.text' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `.text' because `bfd_elf_string_from_elf_section' retrieves the name from the string table section. With a traditional object however the function returns an empty string and consequently `no symbol' is printed instead: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `no symbol' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `no symbol' Restore the original semantics so that the section name is always correctly retrieved. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Also use the section name if `bfd_elf_string_from_elf_section' returns an empty string. ld/ * testsuite/ld-mips-elf/reloc-local-overflow.d: New test. * testsuite/ld-mips-elf/reloc-local-overflow.s: Source for the new test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

2016-05-25MIPS/BFD: Report `bfd_reloc_outofrange' errors as suchMaciej W. Rozycki2-2/+9
A `bfd_reloc_outofrange' condition from `mips_elf_calculate_relocation' currently triggers the warning callback, which in the case of LD prints messages like: foo.o: In function `foo': (.text+0x0): warning: JALX to a non-word-aligned address or: foo.o: In function `foo': (.text+0x0): warning: PC-relative load from unaligned address and nothing else, which suggests this is a benign condition and link has otherwise successfully run to completion. This is however not the case, the link terminates right away with no further messages and no output produced. Use the general error or warning info callback then, preserving the message format. Also set a BFD error condition so that a failure is unambiguously reported. Complement the change with a set of suitable test suite additions. bfd/ * elfxx-mips.c (_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Call `->einfo' rather than `->warning'.

2016-05-25Enable 64-bit archives in ar and ranlibH.J. Lu12-63/+266
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the plugin target is used to create archive in plugin-enabled ar, we need a way to enable 64-bit archives in the plugin target. This patch adds --enable-64-bit-archive to bfd to force 64-bit archives in ar and ranlib. Since both 64-bit MIPS and s390 ELF targets currently use 64-bit archives, 64-bit archives are enabled by default for them. 64-bit archive is generated automatically if the archive is too big. Tested on Linux/x86 and Linux/x86-64 with existing ld and gold. bfd/ PR binutils/14625 * archive.c (bfd_slurp_armap): Replace bfd_elf64_archive_slurp_armap with _bfd_archive_64_bit_slurp_armap.

2016-05-25Skip an archive element if not added by linkerH.J. Lu8-9/+25

2016-05-20MIPS: Fix the encoding of immediates with microMIPS JALXMaciej W. Rozycki2-2/+15
The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation with microMIPS J/JAL/JALS instructions, however unlike the latters its encoded immediate argument is unusually shifted left by 2 rather than 1 in calculating the value used for the operation requested. We already handle this exception in `mips_elf_calculate_relocation' in LD, in a scenario where JALX is produced as a result of relaxing JAL for the purpose of making a cross-mode jump. We also get it right in the disassembler in `decode_micromips_operand'. What we don't correctly do however is processing microMIPS JALX produced by GAS from an assembly source, where a non-zero constant argument or a symbol reference with a non-zero in-place addend has been used. In this case the same calculation is made as for microMIPS J/JAL/JALS, causing the wrong encoding to be produced by GAS on making an object file, and then again by LD in the final link. The latter in particular causes the calculation, where the addend fits in the relocatable field, to produce different final addresses for the same source code depending on whether REL or RELA relocations are used. Correct these issues by special-casing microMIPS JALX in the places that have been previously missed. bfd/ * elfxx-mips.c (mips_elf_read_rel_addend): Adjust the addend for microMIPS JALX. gas/ * config/tc-mips.c (append_insn): Correct the encoding of a constant argument for microMIPS JALX.

The `am34-*-linux*' target cannot be configured for, `am34' is not a CPU name recognized by `config.sub'. It has never been, required code has not been contributed to GNU config, neither before nor since the addition of the target triplet to our configury with commit bfff16424942 ("Add MN10300 linker relaxation support for symbol differences") back in 2007. Also there is no difference in actual tool configuration between the `am34-*-linux*' and `am33_2.0-*-linux*' targets, except from a different executable prefix and tooldir name. Given the above remove the target triplet from our configuration. bfd/ * config.bfd: Remove `am34-*-linux*' support. ld/ * configure.tgt: Remove `am34-*-linux*' support.

A linker script may put .rela.plt in with other .rela.dyn relocs. The change to elf_reloc_type_class puts any PLT relocs last.
