2020-11-03gold: ensure file_counts_lock is initialized before usingNick Gasson2-188/+224
Since upgrading to binutils 2.35 I've been experiencing random memory corruption related crashes with ld.gold --threads. It's caused by multiple threads concurrently pushing elements onto the shared std::vector in File_read::record_file_read(). This vector is supposed to be protected by file_counts_lock, but that is initialized lazily and might be NULL when File_read::open() is called, in which case Hold_optional_lock silently skips locking it. Fix by calling the initialize() method before attempting to acquire the lock, the same as other places that use file_counts_lock.

2018-12-18[GOLD] Tweak keep_text_section_prefix test for PowerPC64 ELFv1Alan Modra2-2/+2
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.

2018-06-21Fix treatment of symbol versions with unused as-needed libraries.Cary Coutant8-2/+190
When we have a weak reference to a symbol defined in an as-needed library, and that library ends up not-needed, gold simply clears the version information in the symbol table, even if the symbol could have been resolved by a needed library later in the link order. This results in a loss of version information, which can cause the program to bind to the wrong version at run time. This patch lets a dynamic definition override an earlier one if the earlier one is from a not-needed library, so that we can retain the version information from the binding to the needed library. In order to do that, the tracking of needed/not-needed had to be moved up to symbol resolution time, instead of during Symbol_table::set_dynsym_indexes(). In cases where we still end up discarding version information, I've added a warning.

2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi1-1104/+3206
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.
