I get some spurious changes when running autoconf/automake for various projects in the tree. This is likely because they were generated using distro-patched tools last time.

2019-07-13[GOLD] PowerPC notoc eh_frameAlan Modra6-117/+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.

2018-12-18[GOLD] Tweak keep_text_section_prefix test for PowerPC64 ELFv1Alan Modra3-2/+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 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.

2018-07-14Fix internal error when using --emit-relocs with plugins.Cary Coutant4-5/+17
When an .eh_frame section has deferred layout because of plugins, gold was neglecting to mark the section as deferred. When we later processed the corresponding relocation section, we were then ignoring it, causing the internal error later on in the link. gold/ PR gold/23397 * object.cc (Sized_relobj_file::do_layout): Mark section as deferred. * testsuite/Makefile.am (plugin_test_1): Add --emit-relocs option to existing test case. * testsuite/Makefile.in: Regenerate.
2018-07-14Fix problem causing duplicated linker-generated symbols with versions.Cary Coutant7-4/+112
When generating _end, _edata, etc. symbols, and a version script provides a version name, and we are linking against another shared library that provides those symbols with a different version, gold ends up trying to resolve the other shared library's symbols to the new definitions, resulting in two copies of each symbol, one as default, and one as non-default. This patch tests for that condition, and ignores the symbols provided by the other shared library. gold/ PR gold/23409 * symtab.cc (Symbol_table::define_special_symbol): Add check for version name on existing symbol. * testsuite/Makefile.am (ver_test_pr23409): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/ver_test_pr23409.sh: New test script. * testsuite/ver_test_pr23409_1.script: New version script. * testsuite/ver_test_pr23409_2.script: New version script.
