2014-10-17Fix ld tests with sysroot=/ and --enable-targets=all and test --print-sysrootHans-Peter Nilsson3-23/+40
* ld-scripts/sysroot-prefix.exp: Log $ld_sysroot. Handle sysroot == "/" as a separate sysroot-configuration with separable test-types. (sysroot_prefix_tests): Include all existing sysroot tests in sysroot == "/" tests except exclude those where a --sysroot option is not specified. * lib/ld-lib.exp (check_sysroot_available): Rewrite to use --print-sysroot instead of relying on error code from using --sysroot=... Also, set $ld_sysroot. The reason we exclude not just the failing "full-path =-prefixed without" but also the passing "plain =-prefixed without but -Lpath" for sysroot == "/" is that for the latter to succeed, we have to make assumptions about the system not having a /sysroot directory or assumptions about its contents etc. When passing --enable-targets=all --enable-64-bit-bfd (the latter not required for a "64-bit-host" of course) the ld --help output got too much to handle for poor tcl (or maybe dejagnu is to blame) and remote_exec exited with an error, so the configuration being tested was mishandled as being a sysroot-less configuration. Using --version instead of --help would work too, but the new --print-sysroot option calls for nominal coverage, so why not use that instead.

* ldlex.l (INPUTLIST): New start condition.

(input_list): New wrapper rule for input_list1, setting INPUTLIST lexer state for the duration of parsing input_list1. All this to say INPUT(=/path/to/file) and not be forced to use INPUT("=/path/to/file") whenever there's a need to force a sysroot- prefix. Still, IMHO it seems better to make use of a previously invalid syntax and not only change the meaning of quoted =-prefixed paths (though arguably that's not very useful before this patchset). This got a little bit hairier than I'd expected: I had to add a new lexer state (aka. start condition) to avoid a first "=" being lexed as the token "=", despite that not making sense in constructs expecting file-names in the first place. (The grammar doesn't allow for expressions in any part of those lists.) I guess I *could* have made it work using that token anyway, but I didn't like the idea that you would be able to separate the "=" from the rest of the file-name with whitespace.

2014-10-04Discard zero address range eh_frame FDEsAlan Modra10-14/+30
These are useless because they can't match any address. In fact, worse than useless because the .eh_frame_hdr lookup table matching addresses to FDEs does not contain information about the FDE range. The table is sorted by address; Range is inferred by the address delta from one entry to the next. So if a zero address range FDE is followed by a normal non-zero range FDE for the same address, everything is good. However, the qsort could just as easily sort the FDEs in the other order, in which case the normal FDE would effectively be seen to have a zero range. bfd/ PR 17447 * elf-bfd.h (struct eh_cie_fde): Comment re NULL u.fde.cie_inf. * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Mark zero address range FDEs for discarding.

2014-09-16NDS32: Code refactoring of relaxation.Kuan-Lin Chen2-111/+28
Refactor each relaxation pattern to raise the maintainability. In origin, all patterns is analysed in nds32_elf_relax_section, so it is hard to debug and maintain. Therefore, we classify all patterns into different functions in this patch. Moreover, we adjust all optimizations into nds32_elf_relax_section to take these optimizations in turn. This can promise all relaxation being done after calling gld${EMULATION_NAME}_after_allocation.

2014-09-11Move ELF section headers to end of object fileAlan Modra31-42/+76
Currently, section ordering differs a little for non-loaded reloc sections output by ld -emit-relocs or ld -r and that after passing such objects through objcopy. Not that it really matters, but it would be better for a simple objcopy to produce an unchanged output object file. Also, section headers are put somewhere in the middle of the non-loaded sections, again slightly differently for ld and objcopy.

2014-09-08Change pe/coff build-id section name to '.buildid'Jon TURNEY3-10/+16
The section name used to store the build-id on pe/coff is arbitrary, as it's contents should be located using the pe/coff header's DataDirectory debug data entry, not by using the section name. But '.build-id' is not a good choice for that section name, as it is 9 characters long, and hence truncated to 8 characters when --disable-long-section-names is used (which is the default, when producing an executable with no dwarf debug sections, e.g. using ld --strip-all --build-id) This truncation then breaks 'objcopy --only-keep-debug', which does use the section name, due to concerns that keeping an arbitrary section which contains the debug directory is not sensible. binutils/ChangeLog 2014-09-01 Jon TURNEY <jon.turney@dronecode.org.uk> * objcopy.c (is_nondebug_keep_contents_section): Change pe/coff build-id section name from '.build-id' to '.buildid'. ld/ChangeLog 2014-09-01 Jon TURNEY <jon.turney@dronecode.org.uk> * emultempl/pe.em (write_build_id, setup_build_id): Change pe/coff build-id section name from '.build-id' to '.buildid'. * emultempl/pep.em (write_build_id, setup_build_id): Ditto.

Do not force -32, -EB and ld emulation but instead rely on the test driver to build for some form of O32. * ld-mips-elf/abiflags-strip2-ph.d: Likewise. * ld-mips-elf/abiflags-strip3-ph.d: Likewise. * ld-mips-elf/abiflags-strip4-ph.d: Likewise. * ld-mips-elf/abiflags-strip5-ph.d: Likewise. * ld-mips-elf/abiflags-strip6-ph.d: Likewise. * ld-mips-elf/abiflags-strip7-ph.d: Likewise. * ld-mips-elf/abiflags-strip8-ph.d: Likewise. * ld-mips-elf/abiflags-strip9-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-0-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-05.d: Likewise. * ld-mips-elf/attr-gnu-4-06.d: Likewise. * ld-mips-elf/attr-gnu-4-07.d: Likewise. * ld-mips-elf/attr-gnu-4-1-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-10.d: Likewise. * ld-mips-elf/attr-gnu-4-15.d: Likewise. * ld-mips-elf/attr-gnu-4-16.d: Likewise. * ld-mips-elf/attr-gnu-4-17.d: Likewise. * ld-mips-elf/attr-gnu-4-2-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-25.d: Likewise. * ld-mips-elf/attr-gnu-4-26.d: Likewise. * ld-mips-elf/attr-gnu-4-27.d: Likewise. * ld-mips-elf/attr-gnu-4-3-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-35.d: Likewise. * ld-mips-elf/attr-gnu-4-36.d: Likewise. * ld-mips-elf/attr-gnu-4-37.d: Likewise. * ld-mips-elf/attr-gnu-4-4-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-45.d: Likewise. * ld-mips-elf/attr-gnu-4-46.d: Likewise. * ld-mips-elf/attr-gnu-4-47.d: Likewise. * ld-mips-elf/attr-gnu-4-5-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-50.d: Likewise. * ld-mips-elf/attr-gnu-4-51.d: Likewise. * ld-mips-elf/attr-gnu-4-52.d: Likewise. * ld-mips-elf/attr-gnu-4-53.d: Likewise. * ld-mips-elf/attr-gnu-4-54.d: Likewise. * ld-mips-elf/attr-gnu-4-55.d: Likewise. * ld-mips-elf/attr-gnu-4-56.d: Likewise. * ld-mips-elf/attr-gnu-4-57.d: Likewise. * ld-mips-elf/attr-gnu-4-58.d: Likewise. * ld-mips-elf/attr-gnu-4-6-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-60.d: Likewise. * ld-mips-elf/attr-gnu-4-61.d: Likewise. * ld-mips-elf/attr-gnu-4-62.d: Likewise. * ld-mips-elf/attr-gnu-4-63.d: Likewise. * ld-mips-elf/attr-gnu-4-64.d: Likewise. * ld-mips-elf/attr-gnu-4-65.d: Likewise. * ld-mips-elf/attr-gnu-4-66.d: Likewise. * ld-mips-elf/attr-gnu-4-67.d: Likewise. * ld-mips-elf/attr-gnu-4-68.d: Likewise. * ld-mips-elf/attr-gnu-4-7-ph.d: Likewise. * ld-mips-elf/attr-gnu-4-70.d: Likewise. * ld-mips-elf/attr-gnu-4-71.d: Likewise. * ld-mips-elf/attr-gnu-4-72.d: Likewise. * ld-mips-elf/attr-gnu-4-73.d: Likewise. * ld-mips-elf/attr-gnu-4-74.d: Likewise. * ld-mips-elf/attr-gnu-4-75.d: Likewise. * ld-mips-elf/attr-gnu-4-76.d: Likewise. * ld-mips-elf/attr-gnu-4-77.d: Likewise. * ld-mips-elf/attr-gnu-4-78.d: Likewise. * ld-mips-elf/mips-elf.exp: Update default abi_asflags(o32) to explicitly pass -32 for the 'no abi' configurations.

* lib/ld-lib.exp (ld_simple_link_defsyms): Provide both __main and ___main for windows targets.
