* [GOLD] OSABI not set when STT_GNU_IFUNC or STB_GNU_UNIQUE symbols outputAlan Modra2019-11-194-4/+52
| | | | | | | | | | | | | | | | | | | | | | This patch arranges to have OSABI set to ELFOSABI_GNU (if not set to some other non-zero value) when gold outputs an ifunc local or global symbol, or a unique global symbol to either .dynsym or .symtab. STT_GNU_IFUNC and STB_GNU_UNIQUE have values in the LOOS to HIOS range and therefore require interpretation according to OSABI. I'm not sure why parameters->target() is const Target& while parameters->sized_target() is Sized_target*, but it's inconvenient to use the latter in Symbol_table::finalize. So this patch adds another const_cast complained about in layout.cc and gold.cc.

* [GOLD] PowerPC notoc eh_frameAlan Modra2019-07-136-117/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When generating notoc call and branch stubs without the benefit of pc-relative insns, the stubs need to use LR to access the run time PC. All LR changes must be described in .eh_frame if we're to support unwinding through asynchronous exceptions. That's what this patch does. The patch has gone through way too many iterations. At first I attempted to add multiple FDEs, one for each stub. That ran into difficulties with do_plt_fde_location which is only capable of setting the address of a single FDE per Output_data section, and with removing any FDEs added on a previous do_relax pass. Removing FDEs (git commit be897fb774) went overboard in matching the FDE contents. That means either stashing the contents created for add_eh_frame_for_plt to use when calling remove_eh_frame_for_plt, or recreating contents on the fly (*) just to remove FDEs. In fact, FDE content matching is quite unnecesary. FDEs added by a previous do_relax pass are those with u_.from_linker.post_map set. So they can easily be recognised just by looking at that flag. This patch keeps that part of the multiple FDE changes. In the end I went for just one FDE per stub group to describe the call stubs. That's reasonably efficient for the common case of only needing to describe the __tls_get_addr_opt call stub. We don't expect to be making many calls using notoc stubs without pc-relative insns. *) Which has it's own set of problems. The contents must be recreated using the old stub layout, but .eh_frame size can affect stub requirements so you need to temporarily keep the old .eh_frame size when creating new stubs, then reset .eh_frame size before adding new FDEs. * ehframe.cc (Fde::operator==): Delete. (Cie::remove_fde): Delete. (Eh_frame::remove_ehframe_for_plt): Delete fde_data and fde_length parameters.

* [GOLD] Tweak keep_text_section_prefix test for PowerPC64 ELFv1Alan Modra2018-12-183-2/+8
| | | | | | | | | | | | | | | | | | | This test checks code layout by function symbol ordering, but that doesn't work on powerpc64 ELFv1 where the function symbol is on a descriptor. A simple work-around is to have nm emit synthetic symbols marking the code entry point of functions. Since the text segment is laid out before the data segment, the synthetic symbols will have lower addresses than function descriptor symbols and be seen first in nm -n output. On other targets, nm --synthetic typically emits symbols on plt entries. Since the testcase doesn't call any of the functions of interest there shouldn't be plt entries for those functions, so there should be no potentially confusing extra symbols. * testsuite/Makefile.am (keep_text_section_prefix_nm.stdout): Pass --synthetic to nm. * testsuite/Makefile.in: Regenerate.

| | | | | | | | | | | | | | | | | | | | | | The ELF compression header has a field (ch_addralign) that is set to the alignment of the uncompressed section. This way the section itself can have a different alignment than the decompressed section. Update decompress_input_section to get alignment of the decompressed section and use it when merging decompressed strings.

* [GOLD] justsyms_exec test fail on powerpc64Alan Modra2018-11-264-4/+11
| | | | | | | | | | | | | | This test fails on powerpc64le due to the justsyms_lib being built with exported_data at 0x2010000, apparently due to the powerpc target code generating an empty relro .branch_lt section. Since the test relies on the library having exported_data at 0x2000000, avoid the problem by linking with -z norelro. Also, the test doesn't need to avoid checking the function symbol on powerpc elfv2. * testsuite/Makefile.am (justsyms_lib): Link with -z norelro. * testsuite/Makefile.in: Regenerate. * testsuite/justsyms_exec.c (main): Do check exported_func on PowerPC64 ELFv2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch allows the gold testsuite to pass when using something like the following configure line, which works for the rest of the binutils testsuite. At least, it does if you don't configure your gcc with any of the options that force a particular path to as or ld. gccdir="/home/alan/build/gcc/prev-" gccsrc="/home/alan/src/gcc.git" gcctarg="x86_64-linux" CC="${gccdir}gcc/xgcc -B${gccdir}gcc/" \ CXX="${gccdir}gcc/xg++ -B${gccdir}gcc/ -I${gccdir}$gcctarg/libstdc++-v3/include -I${gccdir}$gcctarg/libstdc++-v3/include/$gcctarg -I${gccsrc}/libstdc++-v3/libsupc++ -L${gccdir}$gcctarg/libstdc++-v3/src/.libs/" \ ~/src/binutils-gdb/configure ... gold's -Bgcctestdir/ option must come before the -B supplied by $CC or $CXX, in order to pick up the linker we want to test. Also when using a not-yet-installed gcc, it is necessary to provide a collect-ld in gcctestdir/ as otherwise a collect-ld script in -B${gccdir}gcc/ will be used and the wrong linker tested. Besides this, the patch fixes some bugs: The $COMPILE -D_FORTIFY_SOURCE edit was wrong (but worked for usual values), and the $CXXLINK_S edit unnecessarily but harmlessly used extra backslash quoting. See posix shell documentation regarding quoting, or www.gnu.org/software/bash/manual/bashref.html#Command-Substitution Also, -Bgcctestdir/ in one place makes it less likely a new test will be added that accidentally lacks the option. * Makefile.am (gcctestdir1/ld): Use $@ and absolute paths.
