* AVR: Assembler now prepares for linker relaxation by default.Andrew Burgess2014-12-246-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment.

* AVR/ld: Propagate link-relax elf header flag correctly.Andrew Burgess2014-12-2311-0/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AVR target has an elf header flag to indicate if an object was assembler ready for linker relaxation. If a partial link is performed then it is important that the link-relax flag in the output object is set correctly, otherwise, during the final link, we might try to perform linker relaxation on code that was not assembled suitably. As the link-relax elf header covers the entire object file we must be conservative when setting the flag in the output object, so, for a partial link, any input object that does not have the link-relax flag set will cause the output object to also not have the link-relax flag set. This conservative approach could be softened in future, we only need to disable the link relax flag if an input file is not marked link-relax ready, and the input file contains a relaxable section. However, I've left this optimisation for a later day. For the final link I've overloaded the use of the link-relax elf header flag, in a final executable, the flag now indicates if the executable was built with linker relaxation on or not. ld/ChangeLog: * emultempl/avrelf.em: Add include of elf/avr.h.

* Optimize out i386/x86-64 JUMP_SLOT relocationH.J. Lu2014-11-256-0/+107

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.

* Fix ld tests with sysroot=/ and --enable-targets=all and test --print-sysrootHans-Peter Nilsson2014-10-173-23/+40

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.

* Discard zero address range eh_frame FDEsAlan Modra2014-10-0410-14/+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.
