2020-05-18Remove NO_CTORS_DTORS_SECTIONS macroFlorian Weimer
This was originally added to support binutils older than version 2.22: <https://sourceware.org/ml/libc-alpha/2010-12/msg00051.html> Since 2.22 is older than the minimum required binutils version for building glibc, we no longer need this. (The changes do not impact the statically linked startup code.)

2019-12-03Expand $(as-needed) and $(no-as-needed) throughout the build systemFlorian Weimer
Since commit a3cc4f48e94f32c9532ee36982ac00eb1e5719b0 ("Remove --as-needed configure test."), --as-needed support is no longer optional. The macros are not much shorter and do not provide documentary value, either, so this commit removes them.

2018-12-10Use gen-as-const.py to process .pysym files.Joseph Myers
This patch eliminates the gen-py-const.awk variant of gen-as-const, switching to use of gnu-as-const.py (with a new --python option) to process .pysym files (i.e., to generate nptl_lock_constants.py), as the syntax of those files is identical to that of .sym files. Note that the generated nptl_lock_constants.py is *not* identical to the version generated by the awk script. Apart from the trivial changes (comment referencing the new script, and output being sorted), the constant FUTEX_WAITERS, PTHREAD_MUTEXATTR_FLAG_BITS, PTHREAD_MUTEXATTR_FLAG_PSHARED and PTHREAD_MUTEX_PRIO_CEILING_MASK are now output as positive rather than negative constants (on x86_64 anyway; maybe not necessarily on 32-bit systems): < FUTEX_WAITERS = -2147483648 --- > FUTEX_WAITERS = 2147483648 < PTHREAD_MUTEXATTR_FLAG_BITS = -251662336 < PTHREAD_MUTEXATTR_FLAG_PSHARED = -2147483648 --- > PTHREAD_MUTEXATTR_FLAG_BITS = 4043304960 > PTHREAD_MUTEXATTR_FLAG_PSHARED = 2147483648 < PTHREAD_MUTEX_PRIO_CEILING_MASK = -524288 --- > PTHREAD_MUTEX_PRIO_CEILING_MASK = 4294443008 This is because gen-as-const has a cast of the constant value to long int, which gen-py-const lacks. I think the positive values are more logically correct, since the constants in question are in fact unsigned in C. But to reliably produce gen-as-const.py output for constants that always (in C and Python) reflects the signedness of values with the high bit of "long int" set would mean more complicated logic needs to be used in computing values. The more correct positive values by themselves produce a failure of nptl/test-mutexattr-printers, because masking with ~PTHREAD_MUTEXATTR_FLAG_BITS & ~PTHREAD_MUTEX_NO_ELISION_NP now leaves a bit -1 << 32 in the Python value, resulting in a KeyError exception. To avoid that, places masking with ~ of one of the constants in question are changed to mask with 0xffffffff as well (this reflects how ~ in Python applies to an infinite-precision integer whereas ~ in C does not do any promotions beyond the width of int). Tested for x86_64. * scripts/gen-as-const.py (main): Handle --python option. * scripts/gen-py-const.awk: Remove. * Makerules (py-const-script): Use gen-as-const.py.

2018-11-30Replace gen-as-const.awk by gen-as-const.py.Joseph Myers
This patch replaces gen-as-const.awk, and some fragments of the Makefile code that used it, by a Python script. The point is not such much that awk is problematic for this particular script, as that I'd like to build up a general Python infrastructure for extracting information from C headers, for use in writing tests of such headers. Thus, although this patch does not set up such infrastructure, the compute_c_consts function in gen-as-const.py might be moved to a separate Python module in a subsequent patch as a starting point for such infrastructure. The general idea of the code is the same as in the awk version, but no attempt is made to make the output files textually identical. When generating a header, a dict of constant names and values is generated internally then defines are printed in sorted order (rather than the order in the .sym file, which would have been used before). When generating a test that the values computed match those from a normal header inclusion, the test code is made into a compilation test using _Static_assert, where previously the comparisons were done only when the test was executed. One fragment of test generation (converting the previously generated header to use asconst_* prefixes on its macro names) is still in awk code in the makefiles; only the .sym processing and subsequent execution of the compiler to extract constants have moved to the Python script. Tested for x86_64, and with build-many-glibcs.py. * scripts/gen-as-const.py: New file. * scripts/gen-as-const.awk: Remove. * Makerules ($(common-objpfx)%.h $(common-objpfx)%.h.d): Use gen-as-const.py.

2018-02-23Define GEN_AS_CONST_HEADERS when generating header files [BZ #22792]H.J. Lu
Glibc build generates header files to define constants from special .sym files. If a .sym file includes the same header file which it generates, it leads to circular dependency which may lead to build hang on a many-core machine. Define GEN_AS_CONST_HEADERS when generating header files to avoid circular dependency. <tcb-offsets.h> is needed for i686 and it isn't needed for x86-64 at least since glibc 2.23. Tested on i686 and x86-64.

2017-06-14Remove __need_IOV_MAX and __need_FOPEN_MAX.Zack Weinberg
__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more complicated; the basic deal is that sys/uio.h wants to define a constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a constant named IOV_MAX, with the same meaning. For no apparent reason this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on Linux was being used as a dumping ground for extension functions. So now we have bits/uio_lim.h, which defines __IOV_MAX. bits/xopen_lim.h and sys/uio.h use that to define their respective constants. We also now have bits/uio-ext.h, which is the official Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and stdio_lim.h doesn't define IOV_MAX at all. * bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h * bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file. * bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file. * include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value for IOV_MAX. * misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h.

2017-05-19Also create and use ldbl-compat-choose.h.Joseph Myers
This patch makes the glibc build generate an additional header ldbl-compat-choose.h that defines LONG_DOUBLE_COMPAT_CHOOSE_* macros for each libc and libm symbol, which select one or the other of their arguments based on whether the symbol was added before a change to long double != double. The effect of this is that it is then possible to define a macro maybe_long_double_symbol that automatically acts as either long_double_symbol or weak_alias depending on when the symbol being defined was added. This can be used when building long double functions from type-generic templates. Thus, with this patch ldbl-opt no longer needs special long double implementations of each new libm function added using such a template, and the existing such implementations are removed. This is a step towards being able more generally to use common macros to create all the aliases needed for a libm function, so reducing the amount of special-case code needed in ldbl-opt and ldbl-64-128, and facilitating subsequently adding *f32 / *f64 / *f128 / *f32x / *f64x aliases to existing functions (where the set of aliases that a function should have may depend on the architecture in various ways). Tested with build-many-glibcs.py. Except for on powerpc64le-linux-gnu, installed stripped shared libraries are unchanged by the patch. powerpc64le-linux-gnu is the unique configuration which used ldbl-opt from the start rather than adding a new long double choice after originally only having had long double = double. The effect of the patch there is that various cases that previously used long_double_symbol unconditionally now use weak_alias instead, so .os files contain e.g. a symbol cabsl instead of cabsl@@GLIBC_2.17. The final dynamic symbols and versions in the resulting shared libraries are unchanged (ABI tests pass), as is the disassembly of the shared libraries, but the differences in the .os files still result in different .gnu_hash contents in libm.so; the differences are of no significance and logically using weak_alias is what's most appropriate in those cases. * scripts/versions.awk: Generate ldbl-compat-choose.h. * sysdeps/ieee754/ldbl-opt/math-type-macros-ldouble.h: Include <ldbl-compat-choose.h>.

2017-05-19Create and use first-versions.h with macros for function symbol versions.Joseph Myers
This patch arranges for the glibc build to generate a header first-versions.h that defines macros for the earliest symbol version in which each public symbol (GLIBC_[0-9]* symbol version, name only uses C identifier characters) is available. This is used in sysdeps/ieee754/ldbl-opt/math-type-macros-double.h to replace the manually defined LDOUBLE_*_libm_version macros for various functions defined using type-generic templates, the purpose of which is to use in LONG_DOUBLE_COMPAT tests "was this function originally added before glibc supported long double != double on this platform?". As discussed in <https://sourceware.org/ml/libc-alpha/2016-12/msg00246.html>, I expect this to be useful more generally in reducing the amount of special-case code needed in ldbl-opt and ldbl-64-128. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * scripts/versions.awk: Generate first-versions.h. * sysdeps/ieee754/ldbl-opt/math-type-macros-double.h: Include <first-versions.h>.

2017-05-11Suppress internal declarations for most of the testsuite.Zack Weinberg
This patch adds a new build module called 'testsuite'. 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.

2017-05-09Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.Zack Weinberg
cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all it does is set libof-$(foo) for a list of files. extra-modules.mk does the same thing, but with a different input variable, and doesn't let the caller control the module. Therefore, this patch gives cppflags-iterator.mk a better name, removes extra-modules.mk, and updates all uses of both. * extra-modules.mk: Delete file. * cppflags-iterator.mk: Rename to ... * libof-iterator.mk: ...this.

2016-12-08Add pretty printers for the NPTL lock typesMartin Galvan
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.

2016-07-11Revert "Add pretty printers for the NPTL lock types"Siddhesh Poyarekar
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.

Printers should trigger automatically when trying to print a variable of one of the types mentioned above.

2016-07-05Make copies of cstdlib/cmath and use them [BZ #20314]H.J. Lu
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.

2016-06-23libio: Implement vtable verification [BZ #20191]Florian Weimer
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.

2014-11-19Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar
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 McGrath
2014-09-26Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers
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 Myers
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. ($(common-objpfx)soversions.i): Don't pass default_setname to soversions.awk. * Makerules ($(common-objpfx)abi-versions.h): Don't pass oldest_abi to abi-versions.awk. * config.h.in (GLIBC_OLDEST_ABI): Remove macro undefine. * config.make.in (oldest-abi): Remove variable. * configure.ac (--enable-oldest-abi): Remove configure option. * configure: Regenerated. * csu/version.c (banner) [GLIBC_OLDEST_ABI]: Remove conditional text. * scripts/abi-versions.awk: Do not handle oldest_abi variable. * scripts/soversions.awk: Do not handle default_setname variable. * sysdeps/mach/hurd/configure.ac: Do not handle oldest_abi variable. * sysdeps/mach/hurd/configure: Regenerated. * sysdeps/unix/sysv/linux/configure.ac: Do not handle oldest_abi variable. * sysdeps/unix/sysv/linux/configure: Regenerated.
2014-09-16Include .interp section only for libc.soSiddhesh Poyarekar
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.
2014-06-24Print offending diff when check-abi failsSiddhesh Poyarekar
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.
2014-05-21Consistently use $(elf-objpfx).Joseph Myers
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 $(elf-objpfx). Tested x86_64, including that installed shared libraries are unchanged by the patch. * Makeconfig [$(build-hardcoded-path-in-tests) = yes] (rtld-tests-LDFLAGS): Use $(elf-objpfx) instead of $(common-objpfx)elf/.
