Adhemerval Zanella	c06e10c813	elf: Do not print the cache entry if --inhibit-cache is used So --help informs the correct shared library search path. Reviewed-by: Florian Weimer <fweimer@redhat.com>	2 years ago
Adhemerval Zanella Netto	33237fe83d	Remove --enable-tunables configure option And make always supported. The configure option was added on glibc 2.25 and some features require it (such as hwcap mask, huge pages support, and lock elisition tuning). It also simplifies the build permutations. Changes from v1: * Remove glibc.rtld.dynamic_sort changes, it is orthogonal and needs more discussion. * Cleanup more code. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>	3 years ago

Javier Pello	e76369ed63	elf: Simplify output of hwcap subdirectories in ld.so help The print_hwcap_1 machinery was useful for the legacy hwcaps subdirectories, but it is not worth the trouble now that they are gone.

Paul Eggert	581c785bf3	Update copyright dates with scripts/update-copyrights 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 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: * 912-#endif remote: * 913: remote: * 914- remote: * error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines	4 years ago

Florian Weimer	dad90d5282	elf: Add glibc-hwcaps support for LD_LIBRARY_PATH 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.

Florian Weimer	542923d949	elf: Implement ld.so --version 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).

Florian Weimer	e0f1a58f3d	elf: Implement ld.so --help --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>	6 years ago
