2014-11-25Optimize out i386/x86-64 JUMP_SLOT relocationH.J. Lu9-1/+120
When there are both PLT and GOT references to the same function symbol, linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT reference. A run-time JUMP_SLOT relocation is created to update the GOTPLT slot and a run-time GLOB_DAT relocation is created to update the GOT slot. Both JUMP_SLOT and GLOB_DAT relocations will apply the same symbol value to GOTPLT and GOT slots, respectively, at run-time. This optimization combines GOTPLT and GOT slots into a single GOT slot and removes the run-time JUMP_SLOT relocation. It replaces the regular PLT entry: indirect jump [GOTPLT slot] push relocation index jump PLT0 with an GOT PLT entry with an indirect jump via the GOT slot: indirect jump [GOT slot] nop and resolves PLT reference to the GOT PLT entry. We must avoid this optimization if pointer equality is needed since we don't clear symbol value in this case and the dynamic linker won't update the GOT slot. Otherwise, the resulting binary will get into an infinite loop at run-time. bfd/ * elf32-i386.c (elf_i386_got_plt_entry): New. (elf_i386_pic_got_plt_entry): Likewise.

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.

2014-10-15Allow unquoted = as the first character in ldscript input_list namesHans-Peter Nilsson4-18/+49
* ldlex.l (INPUTLIST): New start condition. (comment pattern, ",", "(", ")", "AS_NEEDED") ({FILENAMECHAR1}{FILENAMECHAR}*, "-l"{FILENAMECHAR}+) (quoted string pattern, whitespace pattern): Add INPUTLIST to valid start conditions.

(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.
