* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-2/+2
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master
* elf: Add glibc-hwcaps support for LD_LIBRARY_PATHFlorian Weimer2020-12-041-1/+67
| | | | | | | | | | | | | | | | | | | | This hacks non-power-set processing into _dl_important_hwcaps. Once the legacy hwcaps handling goes away, the subdirectory handling needs to be reworked, but it is premature to do this while both approaches are still supported. ld.so supports two new arguments, --glibc-hwcaps-prepend and --glibc-hwcaps-mask. Each accepts a colon-separated list of glibc-hwcaps subdirectory names. The prepend option adds additional subdirectories that are searched first, in the specified order. The mask option restricts the automatically selected subdirectories to those listed in the option argument. For example, on systems where /usr/lib64 is on the library search path, --glibc-hwcaps-prepend=valgrind:debug causes the dynamic loader to search the directories /usr/lib64/glibc-hwcaps/valgrind and /usr/lib64/glibc-hwcaps/debug just before /usr/lib64 is searched.

* elf: Print the full name of the dynamic loader in the ld.so help messageFlorian Weimer2020-10-081-0/+2
| | | | | | | | This requires defining a macro for the full path, matching the -Wl,--dynamic-link= arguments used for linking glibc programs, and ldd script. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* elf: Use the term "program interpreter" in the ld.so help messageFlorian Weimer2020-10-081-11/+11
| | | | | | This is the term that the ELF standard itself uses. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* elf: Implement ld.so --versionFlorian Weimer2020-10-081-0/+15
| | | | | | | | This prints out version information for the dynamic loader and exits immediately, without further command line processing (which seems to match what some GNU tools do). Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* elf: Implement ld.so --helpFlorian Weimer2020-10-081-4/+20
| | | | | | | | | | | | | | | --help processing is deferred to the point where the executable has been loaded, so that it is possible to eventually include information from the main executable in the help output. As suggested in the GNU command-line interface guidelines, the help message is printed to standard output, and the exit status is successful. Handle usage errors closer to the GNU command-line interface guidelines. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
