* testrun.sh: Add support for --tool=rpctraceSergey Bugaev2021-09-101-2/+7
| | | | | | | | | | rpctrace(1) is a Hurd RPC tracer tool, which is used similar to how strace(1) is used on GNU/Linux.

* Install shared objects under their ABI namesFlorian Weimer2021-06-281-6/+0
| | | | | | | | | | | | | Previously, the installed objects were named like libc-2.33.so, and the ABI soname libc.so.6 was just a symbolic link. The Makefile targets to install these symbolic links are no longer needed after this, so they are removed with this commit. The more general $(make-link) command (which invokes scripts/rellns-sh) is retained because other symbolic links are still needed.

* y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella2021-06-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time. This patch exports following rediretions to support 64-bit time: * libc: adjtime adjtimex clock_adjtime clock_getres clock_gettime clock_nanosleep clock_settime cnd_timedwait ctime ctime_r difftime fstat fstatat futimens futimes futimesat getitimer getrusage gettimeofday gmtime gmtime_r localtime localtime_r lstat_time lutimes mktime msgctl mtx_timedlock nanosleep nanosleep ntp_gettime ntp_gettimex ppoll pselec pselect pthread_clockjoin_np pthread_cond_clockwait pthread_cond_timedwait pthread_mutex_clocklock pthread_mutex_timedlock pthread_rwlock_clockrdlock pthread_rwlock_clockwrlock pthread_rwlock_timedrdlock pthread_rwlock_timedwrlock pthread_timedjoin_np recvmmsg sched_rr_get_interval select sem_clockwait semctl semtimedop sem_timedwait setitimer settimeofday shmctl sigtimedwait stat thrd_sleep time timegm timerfd_gettime timerfd_settime timespec_get utime utimensat utimes utimes wait3 wait4 * librt: aio_suspend mq_timedreceive mq_timedsend timer_gettime timer_settime * libanl: gai_suspend Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>

* Set locale related environment variables in debugglibc.shArjun Shankar2020-09-241-0/+9

* test-container: Support $(complocaledir) and mkdirp.Carlos O'Donell2020-04-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Expand the support infrastructure: - Create $(complocaledir) in the testroot.pristine to support localedef. - Add the variable $complocaledir to script support. - Add the script command 'mkdirp'. All localedef tests which run with default paths need to have the $(complocaledir) created in testroot.pristine. The localedef binary will not by itself create the default path, but it will write into the path. By adding this we can simplify the localedef tests. The variable $complocaledir is the value of the configured $(complocaledir) which is the location of the compiled locales that will be searched by the runtime by default. The command mkdirp will be available in script setup and will be equivalent to running `mkdir -p`. The variable and command can be used to write more complex tests.

* Do not use ld.so to open statically linked programs in debugglibc.shGabriel F. T. Gomes2019-12-041-2/+14
| | | | | | | | | | | | | | | Debugging programs that have been dynamically linked against an uninstalled glibc requires unusual steps, such as letting gdb know where the thread db library is located and explicitly calling the loader. However, when the program under test is statically linked, these steps are not required (as a matter of fact, using the dynamic loader to run a statically linked program is wrong and will fail), and gdb should be called the usual way. This patch modifies debugglibc.sh so that it checks if the program under test is statically linked, then runs the debugger appropriately. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* Attach to test in container from debugglibc.shGabriel F. T. Gomes2019-12-041-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some test cases are meant to be ran inside the container infrastructure and make check automatically runs them as such. However, running a single test case in a container without make check is useful. This patch adds a new --tool option to testrun.sh that makes this easy, as well as it adds a new option (-c or --in-container) to debugglibc.sh, which causes the program under test to be ran in a container (with WAIT_FOR_DEBUGGER=1), then automatically attaches GDB to it. Automatically detecting if a test case is supposed to be ran inside a container is harder (if not impossible), as Carlos pointed out [1], however, this patch makes it easier to do it manually: Using testrun.sh with containerized test: $ ./testrun.sh --tool=container /absolute/path/to/program Using debugglibc.sh with containerized test: $ ./debugglibc.sh -c /absolute/path/to/program Note: running these commands with relative paths causes error and warning messages to be displayed, although the test case might succeed. For example, with relative path: $ ./testrun.sh --tool=container elf/tst-ldconfig-bad-aux-cache error: subprocess failed: execv error: unexpected error output from subprocess /sbin/ldconfig: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf: No such file or directory info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache [...] Whereas with absolute paths, the errors and warnings are gone: $ ./testrun.sh --tool=container $PWD/elf/tst-ldconfig-bad-aux-cache info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache [...] [1] https://sourceware.org/ml/libc-alpha/2019-11/msg00873.html Reviewed-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses an issue reported in <https://sourceware.org/ml/libc-alpha/2019-07/msg00661.html> where the creation of testroot.pristine, on encountering LD_TRACE_LOADED_OBJECTS=1 of the form libc.so.6 => /scratch/jmyers/glibc/mbs/obj/glibc-8-0-mips64-linux-gnu-x86_64-linux-gnu/default/libc.so.6 (0x772dd000) /lib32/ld.so.1 => /scratch/jmyers/glibc/mbs/obj/glibc-8-0-mips64-linux-gnu-x86_64-linux-gnu/default/elf/ld.so.1 (0x7747b000) tries to copy /lib32/ld.so.1 (which does not exist) into the testroot instead of copying the path on the RHS of "=>", which does exist, because the Makefile logic assumes that the path on such a line with '/' should be copied, when if there are such paths on both the LHS and the RHS of "=>", only the one on the RHS necessarily exists and so only that should be copied. The patch follows the approach suggested by DJ in <https://sourceware.org/ml/libc-alpha/2019-07/msg00662.html>, with the suggestion from Andreas in <https://sourceware.org/ml/libc-alpha/2019-10/msg00514.html> of a single sed command in place of pipeline of grep and three sed commands. Tested for x86_64, with and without --enable-hardcoded-path-in-tests; a previous version with multiple sed commands, implementing the same logic, also tested for MIPS, with and without --enable-hardcoded-path-in-tests, to confirm it fixes the original problem.

This enables convenient debugging of non-testcase programs such as iconv/iconv_prog or other dynamically linked programs. Program arguments may be passed using `--' as a separator.

* Add helper script for glibc debuggingGabriel F. T. Gomes2019-09-301-1/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new make rule that generates a helper script for debugging glibc test cases. The new script, debugglibc.sh, is similar to testrun.sh, in the sense that it allows the execution of the specified test case, however, it opens the test case in GDB, setting the library path the same way that testrun.sh does. The commands are based on the instructions on the wiki for glibc debugging [1,2]. By default, the script tells GDB to load the test case for symbol information, so that, when a breakpoint is hit, the call stack is displayed correctly (instead of printing lots of '??'s). For instance, after running 'make' and 'make check', one could do the following: $ ./debugglibc.sh nptl/tst-exec1 -b pthread_join Reading symbols from /home/gabriel/build/powerpc64le/glibc//elf/ld.so...done. Breakpoint 1 at 0x1444 add symbol table from file "nptl/tst-exec1" [Thread debugging using libthread_db enabled] Using host libthread_db library "/home/gabriel/build/powerpc64le/glibc//nptl_db/libthread_db.so.1".

Notice that the script will always start GDB with the program running and halted at _dl_start_user. So, in order to reach the actual breakpoint of interest, one should hit 'c', not 'r': >>> c Continuing.

| | | | | | | | | | | | | | | If building on a subset of architectures only, it is easy to miss wrapper headers which are required by other architectures because they lack the corresponding sysdeps header. The check ensures that every installed header which is not itself a sysdeps header has a header under include/ (that presumably wraps the header, and perhaps also adding declarations and definitions for !_ISOMAC). Also check for the absence of the sysdeps/generic/bits directory removed in commit c72565e5f1124c2dc72573e83406fe999e56091f, to make accidental re-introduction more difficult.

Such add-ons may be within the glibc source tree, or outside it at a path passed to the --enable-add-ons configure option. localedata and crypt were once add-ons, distributed in separate release tarballs, but long since stopped using that mechanism. Linuxthreads was always an add-on. Ports spent some time as an add-on with separate release tarballs, then was first moved into the glibc source tree, then had its sysdeps files moved into the main sysdeps hierarchy so the add-ons mechanism was no longer used. NPTL spent some time as an add-on in the main glibc tree before stopping using the add-on mechanism. libidn used to have separate release tarballs but no longer does so, but still uses the add-ons mechanism within the glibc source tree. Various other software has supported building with the add-ons mechanism at times in the past, but I don't think any is still widely used. Add-ons involve significant, little-used complexity in the glibc build system, and make it hard to understand what the space of possible glibc configurations is. This patch removes the add-ons mechanism. libidn is now built via the Subdirs mechanism to cause any configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN (which effectively means shared libraries are available) is now defined via sysdeps/unix/inet/configure. Various references to add-ons around the source tree are removed (in the case of maint.texi, the example list of sysdeps directories is still very out of date). Externally maintained ports should now put their files in the normal sysdeps directory structure rather than being arranged as add-ons; they probably need to change e.g. elf.h anyway, rather than actually being able to work just as a drop-in subtree. Hurd libpthread should be arranged similarly to NPTL, so some files might go in a hurd-pthreads (or similar) top-level directory in glibc, while sysdeps files should go in the normal sysdeps directory structure (possibly in hurd or hurd-pthreads subdirectories, just as there are nptl subdirectories in the sysdeps tree).

IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise.

If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned.

* Remove C++ namespace handling from glibc headers.Joseph Myers2017-03-161-51/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

* Installed header hygiene (BZ#20366): Test of installed headers.Zack Weinberg2016-09-231-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a test to ensure that the problems fixed in the last several patches do not recur. Each directory checks the headers that it installs for two properties: first, each header must be compilable in isolation, as both C and C++, under a representative combination of language and library conformance levels; second, there is a blacklist of identifiers that may not appear in any installed header, currently consisting of the legacy BSD typedefs. (There is an exemption for the headers that define those typedefs, and for the RPC headers. It may be necessary to make this more sophisticated if we add more stuff to the blacklist in the future.) In order for this test to work correctly, every wrapper header that actually defines something must guard those definitions with #ifndef _ISOMAC. This is the existing mechanism used by the conform/ tests to tell wrapper headers not to define anything that the public header wouldn't, and not to use anything from libc-symbols.h. conform/ only cares for headers that we need to check for standards conformance, whereas this test applies to *every* header. (Headers in include/ that are either installed directly, or are internal-use-only and do *not* correspond to any installed header, are not affected.) * scripts/check-installed-headers.sh: New script. * Rules: In each directory that defines header files to be installed, run check-installed-headers.sh on them as a special test. * Makefile: Likewise for the headers installed at top level. * include/aliases.h, include/alloca.h, include/argz.h * include/arpa/nameser.h, include/arpa/nameser_compat.h * include/elf.h, include/envz.h, include/err.h * include/execinfo.h, include/fpu_control.h, include/getopt.h * include/gshadow.h, include/ifaddrs.h, include/libintl.h * include/link.h, include/malloc.h, include/mcheck.h * include/mntent.h, include/netinet/ether.h * include/nss.h, include/obstack.h, include/printf.h * include/pty.h, include/resolv.h, include/rpc/auth.h * include/rpc/auth_des.h, include/rpc/auth_unix.h * include/rpc/clnt.h, include/rpc/des_crypt.h * include/rpc/key_prot.h, include/rpc/netdb.h * include/rpc/pmap_clnt.h, include/rpc/pmap_prot.h * include/rpc/pmap_rmt.h, include/rpc/rpc.h * include/rpc/rpc_msg.h, include/rpc/svc.h * include/rpc/svc_auth.h, include/rpc/xdr.h * include/rpcsvc/nis_callback.h, include/rpcsvc/nislib.h * include/rpcsvc/yp.h, include/rpcsvc/ypclnt.h * include/rpcsvc/ypupd.h, include/shadow.h * include/stdio_ext.h, include/sys/epoll.h * include/sys/file.h, include/sys/gmon.h, include/sys/ioctl.h * include/sys/prctl.h, include/sys/profil.h * include/sys/statfs.h, include/sys/sysctl.h * include/sys/sysinfo.h, include/ttyent.h, include/utmp.h * sysdeps/arm/nacl/include/bits/setjmp.h * sysdeps/mips/include/sys/asm.h * sysdeps/unix/sysv/linux/include/sys/sysinfo.h * sysdeps/unix/sysv/linux/include/sys/timex.h * sysdeps/x86/fpu/include/bits/fenv.h: Add #ifndef _ISOMAC guard around internal declarations.

* Support __STDC_WANT_LIB_EXT2__ feature test macro.Joseph Myers2016-08-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements support for the __STDC_WANT_LIB_EXT2__ feature test macro from ISO/IEC TR 24731-2:2010, thereby implementing one possible approach for supporting ISO C feature test macros. Recall that, as described in <https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these macros work based on the definition when affected headers are included, so cannot be handled once when the first system header is included because that might not be one of the headers the particular macro in question affects. <https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses views on possible approaches for implementation and <https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows up on that. This patch arranges things so that the relevant condition is __GLIBC_USE (LIB_EXT2), following one of the suggestions given. Headers using these macros include <bits/libc-header-start.h>, which in turn includes <features.h>. Headers must define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including <bits/libc-header-start.h>, to discourage inclusion outside glibc as requested. __USE_GNU conditions on affected functions are changed to __GLIBC_USE (LIB_EXT2), while it's added as an additional alternative on the conditions for functions already enabled for some POSIX versions. It would be possible to convert existing __USE_* conditionals to __GLIBC_USE (with the relevant __GLIBC_USE_* being defined in <features.h> where __USE_* are presently defined), and so make them typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE is used with #if not #ifdef / #if defined. No attempt is made to enforce the rule about diagnosing different definitions of __STDC_WANT_LIB_EXT2__ when affected headers are included; such a diagnostic is incompatible with multiple-include guards on the affected headers, unless compiler extensions are added to support it. As previously noted, glibc does not implement all features from TR 24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline are not in glibc, although they would be appropriate to add if someone wished to do so. But I think it makes sense to support the feature test macro if *any* of the controlled features are present in glibc. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h: New file. * Makefile (headers): Add bits/libc-header-start.h. * include/features.h (__STDC_WANT_LIB_EXT2__): Document.

| | | | | | | | | | | | | | | | | | | | Now that GCC 4.7 or later is required to build glibc, this patch moves the build from using -std=gnu99 to -std=gnu11 (option added in 4.7). This allows use of C11 features from GCC's headers, such as new float.h macros and max_align_t. Tested for x86_64 and x86 (testsuite; installed stripped shared libraries are unchanged by the patch on x86_64, while I see some slight code reordering of no significance on x86). * Makeconfig (CFLAGS): Use -std=gnu11 instead of -std=gnu99. * Makefile ($(objpfx)c++-types-check.out): Filter out -std=gnu11 instead of -std=gnu99. * configure.ac (systemtap): Test with -std=gnu11 instead of -std=gnu99. * configure: Regenerated. * math/gen-auto-libm-tests.c: Use -std=gnu11 instead of -std=gnu99 in compilation command in comment.
* Remove support for removing glibc 2.0 headers.Joseph Myers2015-10-261-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a configure test for the presence of glibc 2.0 headers (that were renamed / no longer installed in glibc 2.1) and associated support for removing them on "make install". Normal practice for subsequent removal / renaming of installed files has been not to do anything special about removing them; if you want installed files from an old installation removed reliably, you need to use a packaging system that tracks what files were installed by a previous glibc package (via installing in an intermediate directory with install_root). I think it's been long enough since 2.0 that it's not particularly useful to have that special logic for those old headers either; this patch removes it. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (old_glibc_headers): Remove configure test. * configure: Regenerated. * config.make.in (old-glibc-headers): Remove variable. * Makefile [!$(install_root) && $(old-glibc-headers) = yes] (install): Remove dependency on remove-old-headers.

* Use -Wold-style-definition.Joseph Myers2015-10-211-1/+1
| | | | | | | | | | | | | | | This patch makes glibc build with -Wold-style-definition to avoid old-style function definitions creeping back in by accident. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). Also tested build for arm, mips64 and powerpc32. Hopefully there aren't any remaining system-specific files with old-style definitions whose formatting evaded my searches, but if there are, they will be easy to fix. * Makeconfig (+gccwarn-c): Add -Wold-style-definition. * Makefile ($(objpfx)c++-types-check.out): Filter out $(+gccwarn-c) instead of -Wstrict-prototypes.
* Prevent check-local-headers.sh hang.Carlos O'Donell2015-09-141-1/+1
| | | | | | | | | | | | Consensus in [1] was that the right way to fix this was simply to redirect from /dev/null to terminate the test if no inputs was found by the tests own globbing e.g. "*/*.{o,os,oS}.d" This can happen when the build is incomplete and the tests are started. This failure causes check-local-headers.sh to hang forever waiting for input from stdin. This change makes the test terminate immediately if the glob doesn't return any files.

This patch fixes this by simply inverting the result of the egrep, i.e. succeed if egrep fails (to find failed results) and fail if it succeeds. Tested with 'make subdirs=localedata check' and 'make subdirs=locale check' where all tests succeed and with 'make subdirs=elf check' where a couple of tests fail for me. * Makefile (summarize-tests): Fix return value on success.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Carlos reported failures in conform/ tests in environments where the compiler used could only find headers in glibc's source and build trees, not any previously installed headers <https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>. This patch moves nptl/semaphore.h to sysdeps/pthread/semaphore.h so that it can be found by builds from all glibc subdirectories; it's not in any way NPTL-specific. (I left the Makefile setting to install this header in nptl/, but maybe it should move as well - it's just not clear to me what ifeq ($(subdir),...) conditional should be used to select the directory to associate the header with for installation purposes. The path in the toplevel Makefile used for begin-end-check also remains hardcoded; it's a known todo issue to rework that test to run in each subdirectory checking the headers installed from that subdirectory, rather than a separate hardcoded list.) Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). I did *not* test a configuration such as that in which Carlos saw failure. * nptl/semaphore.h: Move to ... * sysdeps/pthread/semaphore.h: ... here. * Makefile (installed-headers): Change nptl/semaphore.h to sysdeps/pthread/semaphore.h.
