2016-12-08Add pretty printers for the NPTL lock typesMartin Galvan1-0/+46
This patch adds pretty printers for the following NPTL types: - pthread_mutex_t - pthread_mutexattr_t - pthread_cond_t - pthread_condattr_t - pthread_rwlock_t - pthread_rwlockattr_t To load the pretty printers into your gdb session, do the following: python import sys sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers') end source /path/to/glibc/source/pretty-printers/nptl-printers.py You can check which printers are registered and enabled by issuing the 'info pretty-printer' gdb command. Printers should trigger automatically when trying to print a variable of one of the types mentioned above. The printers are architecture-independent, and were tested on an AMD64 running Ubuntu 14.04 and an x86 VM running Fedora 24. In order to work, the printers need to know the values of various flags that are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since replicating these constants in the printers file itself would create a maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses to extract the constants. This script is pretty much the same as gen-as-const.awk, except it doesn't cast the constant values to 'long' and is thorougly documented. The constants need only to be enumerated in a .pysym file, which is then referenced by a Make variable called gen-py-const-headers. As for the install directory, I discussed this with Mike Frysinger and Siddhesh Poyarekar, and we agreed that it can be handled in a separate patch, and shouldn't block merging of this one. In addition, I've written a series of test cases for the pretty printers. Each lock type (mutex, condvar and rwlock) has two test programs, one for itself and other for its related 'attributes' object. Each test program in turn has a PExpect-based Python script that drives gdb and compares its output to the expected printer's. The tests run on the glibc host, which is assumed to have both gdb and PExpect; if either is absent the tests will fail with code 77 (UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper. I've tested the printers on both native builds and a cross build using a Beaglebone Black running Debian, with the build system's filesystem shared with the board through NFS. Finally, I've written a README that explains all this and more. * INSTALL: Regenerated. * Makeconfig: Add comments and whitespace to make the control flow clearer.

2016-09-21Avoid running $(CXX) during build to obtain header file pathsFlorian Weimer1-6/+2
This reduces the build time somewhat and is particularly noticeable during rebuilds with few code changes.
2016-09-20Remove remnants of .og patternsFlorian Weimer1-1/+0
This was used by --enable-omitfp, and the bulk of it was removed in this commit: commit bdeba1354b7364d9b7857a048286a71ddbcdff86 Author: Ulrich Drepper <drepper@gmail.com> Date: Sat Jan 7 11:29:31 2012 -0500 Remove --enable-omitfp support
2016-07-11Revert "Add pretty printers for the NPTL lock types"Siddhesh Poyarekar1-46/+0
This reverts commit 62ce266b0b261def2c6329be9814ffdcc11964d6. The change is not mature enough because it needs the following fixes: 1. Redirect test output to a file like other tests 2. Eliminate the need to use a .gdbinit because distributions will break without it. I should have caught that but I was in too much of a hurry to get the patch in :/ 3. Feature checking during configure to determine things like minimum required gdb version, python-pexpect version, etc. to make sure that tests work correctly.

2016-07-05Make copies of cstdlib/cmath and use them [BZ #20314]H.J. Lu1-0/+24
If C++ headers <cstdlib> or <cmath> are used, GCC 6 will include /usr/include/stdlib.h or /usr/include/math.h from "#include_next" (instead of stdlib/stdlib.h or math/math.h in the glibc source directory), and this turns up as a make dependency. An implicit rule will kick in and make will try to install stdlib/stdlib.h or math/math.h as /usr/include/stdlib.h or /usr/include/math.h because the target is out of date. We make a copy of <cstdlib> and <cmath> in the glibc build directory so that stdlib/stdlib.h and math/math.h will be used instead of /usr/include/stdlib.h and /usr/include/math.h. [BZ #20314] * Makeconfig (CXXFLAGS): Prepend -I$(common-objpfx). * Makerules (before-compile): Add $(common-objpfx)cstdlib and $(common-objpfx)cmath. ($(common-objpfx)cstdlib): New target. ($(common-objpfx)cmath): Likewise.
2016-06-23libio: Implement vtable verification [BZ #20191]Florian Weimer1-0/+3
This commit puts all libio vtables in a dedicated, read-only ELF section, so that they are consecutive in memory. Before any indirect jump, the vtable pointer is checked against the section boundaries, and the process is terminated if the vtable pointer does not fall into the special ELF section. To enable backwards compatibility, a special flag variable (_IO_accept_foreign_vtables), protected by the pointer guard, avoids process termination if libio stream object constructor functions have been called earlier. Such constructor functions are called by the GCC 2.95 libstdc++ library, and this mechanism ensures compatibility with old binaries. Existing callers inside glibc of these functions are adjusted to call the original functions, not the wrappers which enable vtable compatiblity. The compatibility mechanism is used to enable passing FILE * objects across a static dlopen boundary, too.

2015-10-15Remove -static-libgcc configure test.Joseph Myers1-2/+2
There is a configure test for -static-libgcc. GCC added this option in version 3.0, so this test is obsolete; this patch removes it. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_gcc_static_libgcc): Remove configure test. * configure: Regenerated. * config.make.in (static-libgcc): Remove variable. * Makerules (build-shlib-helper): Use -static-libgcc instead of $(static-libgcc).

2015-06-12Attempting to install glibc configured with --prefix=/usr intoMartin Sebor1-0/+20
a non-standard directory specified by the prefix make variable fails with an error. Since this is an unsupported use case, this change makes make install fail early and with a descriptive error message when either the prefix or the exec_prefix make variable is overridden on the command line.

Make runtime-linker.h available outside $(elf-objpfx) by moving the file to $(common-objpfx) and the rules for it to Makerules. Tested for x86_64 and x86 (testsuite, and that no compiled code changed by the patch). * Makeconfig (+interp): Remove unused variable. * elf/Makefile ($(objpfx)interp.os): Define for [$(build-shared) = yes] only. Depend on $(common-objpfx)runtime-linker.h instead of $(elf-objpfx)runtime-linker.h. ($(elf-objpfx)runtime-linker.h): Rename to $(common-objpfx)runtime-linker.h and move ... * Makerules [$(build-shared) = yes]: ... here. * elf/interp.c: Include <runtime-linker.h> instead of <elf/runtime-linker.h>.

2014-11-19Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar1-1/+1
The current scheme to identify which module a translation unit is built in depends on defining multiple macros IS_IN_* and also defining NOT_IN_libc if we're building a non-libc module. In addition, there is an IN_LIB macro that does effectively the same thing, but for different modules (notably the systemtap probes). This macro scheme unifies both ideas to use just one macro IN_MODULE and assign it a value depending on the module it is being built into. If the module is not defined, it defaults to MODULE_libc. Patches that follow will replace uses of IS_IN_* variables with the IS_IN() macro. libc-symbols.h has been converted already to give an example of how such a transition will look. Verified that there are no relevant binary changes. One source change that will crop up repeatedly is that of nscd_stat, since it uses the build timestamp as a constant in its logic. * Makeconfig (in-module): Get value of libof set for the translation unit.

2014-10-31BZ#17496: Fix gnu/lib-names.h dependency.Roland McGrath1-64/+68
2014-09-26Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers1-0/+63
This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64. [BZ #14171] * Makeconfig [$(build-shared) = yes] ($(common-objpfx)soversions.mk): Don't handle SONAMEs specified in makefiles.

2014-09-16Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers1-1/+1
This patch removes the --enable-oldest-abi configure option, which has long been bitrotten (as reported in bug 6652). The principle of removing this option was agreed in the thread starting at <https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>. Tested for x86_64 and x86 that the installed shared libraries other than libc.so are unchanged by this patch and that libc.so disassembly and symbol versions are unchanged (debug info changes because of changed line numbers in csu/version.c). [BZ #6652] * Makeconfig (soversions-default-setname): Remove variable.

2014-09-16Include .interp section only for libc.soSiddhesh Poyarekar1-1/+1
Barring libc.so and libdl.so, none of the libraries have any entry points, so it is pointless to add a .interp section for them. The libdl.so entry point (in dlfcn/eval.c) is also defunct, so remove that file as well. Build tested for x86_64, ppc64 and s390x. I have not moved CFLAGS-interp.c to CPPFLAGS-interp.c isnce I'll be removing it completely in a follow-up patch. Siddhesh * Makerules (lib%.so): Don't include $(+interp) in prerequisites. * elf/Makefile (CFLAGS-interp.c): Don't define NOT_IN_libc. * dlfcn/eval.c: Remove file.

The earlier version of check-abi would print a diff of the expected ABI vs the built ABI when there was a difference. Bring back this behaviour.

As previously noted <https://sourceware.org/ml/libc-alpha/2013-05/msg00696.html>, $(elf-objpfx) and $(elfobjdir) are redundant and should be consolidated. This patch consolidates on $(elf-objpfx) (for consistency with $(csu-objpfx)), also changing direct uses of $(common-objpfx)elf/ to use $(elf-objpfx).

2014-03-06Enumerate tests with special rules in tests-special variable.Joseph Myers1-2/+5
This patch is a revised and updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>. In order to generate overall summaries of the results of all tests in the glibc testsuite, we need to identify and concatenate the files with the results of individual tests. Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this. However, the normal glibc approach is explicit enumeration of the expected set of files with a given property, rather than all files matching some pattern like that. Furthermore, we would like to be able to mark tests as UNRESOLVED if the file with their results is for some reason missing, and in future we would like to be able to mark tests as UNSUPPORTED if they are disabled for a particular configuration (rather than simply having them missing from the list of tests as at present). Such handling of tests that were not run or did not record results requires an explicit enumeration of tests. For the tests following the default makefile rules, $(tests) (and $(xtests)) provides such an enumeration. Others, however, are added directly as dependencies of the "tests" and "xtests" makefile targets. This patch changes the makefiles to put them in variables tests-special and xtests-special, with appropriate dependencies on the tests listed there then being added centrally. Those variables are used in Rules and so need to be set before Rules is included in a subdirectory makefile, which is often earlier in the makefile than the dependencies were present before. We previously discussed the question of where to include Rules; see the question at <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a discussion in <https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why Rules is included early rather than late in subdirectory makefiles. It was necessary to avoid an indirection through the check-abi target and get the check-abi-* targets for individual libraries into the tests-special variable. The intl/ test $(objpfx)tst-gettext.out, previously built only because of dependencies from other tests, was also added to tests-special for the same reason. The entries in tests-special are the full makefile targets, complete with $(objpfx) and .out. If a future change causes tests to be named consistently with a .out suffix, this can be changed to include just the path relative to $(objpfx), without .out. Tested x86_64, including that the same set of files is generated in the build directory by a build and testsuite run both before and after the patch (except for changes to the elf/tst-null-argv.debug.out.<number> file name), and a build with run-built-tests=no to verify there aren't any more obvious instances of the issue Marcus Shawcroft reported with a previous version in <https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>. * Makefile (tests): Change dependencies to ....

2014-02-21Generate .test-result files for tests with special rules.Joseph Myers1-4/+8
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now proposed for inclusion in glibc, extends the generation of PASS and FAIL status in .test-result files for individual tests to cover tests with their own custom makefile rules. This is just adding $(evaluate-test) calls to all such rules, since tests with multiple commands were previously split into separate tests. Note that the tests the makefiles expect to fail (posix/annexc and conformtest) currently get FAIL listed in the .test-result file, rather than XFAIL; a subsequent patch will introduce a better XFAIL mechanism.

2014-02-15Generate .test-result files for ordinary tests.Tomas Dohnalek1-2/+8
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00193.html>, starts the process of generating explicit PASS or FAIL status for individual glibc tests. It's based on Tomas Dohnalek's patch <https://sourceware.org/ml/libc-alpha/2012-10/msg00278.html>, but is deliberately more minimal: it doesn't try to cover any tests outside of $(tests) / $(xtests) (that's for a later patch), nor does it put the result together in an overall summary file (again, a later patch): it just generates the .test-result files. Thus, this patch keeps the overall logic for when a testsuite run finishes completely unchanged: a test failing will terminate the run. I think we *should* move to a more conventional approach where plain "make check" does not terminate for an individual test failure, unless e.g. you say "make stop-on-test-failure=y check", but that sort of policy change is best done as a separate patch once the infrastructure is in place to generate summary files for completed test runs (which will entirely consist of PASS and XFAIL lines if the testsuite run reaches the point of generating them, until such a policy change is made). Tested x86_64. 2014-02-14 Tomas Dohnalek <tdohnale@redhat.com> Joseph Myers <joseph@codesourcery.com> * Makeconfig (test-name): New variable. (evaluate-test): Likewise. * Makerules (do-test-clean): Remove .test-result files.

2014-02-12Make ABI tests generate .out files.Joseph Myers1-9/+13
If you rerun "make check" in a tree where some tests have already been run, it will rerun ABI tests because those do not create an output file. This patch changes those tests to create .out files so they only get rerun if the dependencies (on the ABI baselines and the generated .symlist files) indicate they should be rerun. Tested x86_64. * Makerules (check-abi-%): Change target to $(objpfx)check-abi-%.out. (check-abi target): Update dependencies. (check-abi-pattern variable): Redirect output of diff to $@.

This patch creates implicit rules to match the abifiles if abilist-pattern is defined in the architecture Makefile. This allows machine specific Makefiles to define different abifiles names (for instance *-le.abilist for powerpc64le).

2013-10-03Fix erroneous (and circular) implied pattern rule for linkobj/libc.so.Brooks Moses1-3/+34
[BZ #15915] As described in the bug, the pattern rule for lib%.so files in Makerules includes linkobj/libc.so as a dependency. However, the explicit rule for linkobj/libc.so is in the top-level Makefile. Thus, the subdirectory makefiles that include Makerules end up with an erroneous makefile pattern rule for linkobj/libc.so that includes itself as a dependency. The result is make warnings whenever rules for other .so files are resolved -- and, on occasion, actual makefile failures when a race condition causes the implicit rule to actually be used. This patch moves the explicit rules for linkobj/libc.so into Makerules to clear up this problem. It also elaborates a couple of comments that I'd initially found confusing.

2012-08-22rename V variable to lib-versionMike Frysinger1-2/+2
Due to the rise of kbuild type build systems (as the Linux kernel is a popularly emulated environment), the V variable has become common as a knob for controlling verbosity. Unfortunately, if you run `make V=1` with glibc during install, it fails with weird errors due to the glibc build already using this variable for versioning information. Granted, overriding this variable in the glibc context makes no sense so people shouldn't be doing it, but when paired with build frameworks that like to use one set of options for all packages, glibc starts to stick out as an oddball (in that it fails). Considering it's easy enough to rename (it's used in just one place), let's do so. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
