* Remove CALL_THREAD_FCT macroAdhemerval Zanella2017-04-041-46/+0
| | | | | | | | | | | | | | | | This patch removes CALL_THREAD_FCT macro usage and its defition for x86. For 32 bits it usage is only for force 16 stack alignment, however stack is already explicit aligned in clone syscall. For 64 bits and x32 it just a function call and there is no need to code it with inline assembly. Checked on i686-linux-gnu, x86_64-linux-gnu, and x86_64-linux-gnu-x32. * nptl/pthread_create.c (START_THREAD_DEFN): Remove CALL_THREAD_FCT macro usage. * sysdeps/i386/nptl/tls.h (CALL_THREAD_FCT): Remove definition. * sysdeps/x86_64/nptl/tls.h (CALL_THREAD_FCT): Likewise. * sysdeps/x86_64/32/nptl/tls.h: Remove file.

* Update lrint/lrintf/lrintl for x32H.J. Lu2015-10-093-0/+84
| | | | | | | | | | | | | | | | | | | | | | The x86_64 versions of lrint/lrintf/ lrintl are aliases for the long long versions which isn't correct for x32, where exceptions must respect overflow for 32-bit long. Separate versions of the long functions for x32 that convert to 32-bit long and raise the right exceptions for that conversion, while keeping the aliases in the non-x32 case. Tested on x86_64 and x32. There are no code changes in libm.so on x86_64. * sysdeps/x86_64/fpu/s_llrint.S (__lrint): Add alias only if __ILP32__ isn't defined.

* Don't use dbl-64/wordsize-64 lround based on llround for ILP32 (bug 19079).Joseph Myers2015-10-071-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of lround in dbl-64/wordsize-64 as an alias or wrapper for llround is always incorrect when long is not 64-bit, because it misses required exceptions in overflow cases, as shown by my recently added tests. This patch removes that alias / wrapper in the non-LP64 case, together with the REGISTER_CAST_INT32_TO_INT64 macro, restoring the previous version of lround for dbl-64/wordsize-64 (newly conditioned on !_LP64). Tested for x86_64, and for mips64 with use of dbl-64/wordsize-64 enabled. [BZ #19079] * sysdeps/ieee754/dbl-64/wordsize-64/s_lround.c: Restore previous file, conditioned on [!_LP64]. * sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c [!_LP64] (__lround): Do not define as function or alias. [!_LP64] (lround): Likewise. [!_LP64] (__lroundl): Likewise. [!_LP64] (lroundl): Likewise. * sysdeps/tile/sysdep.h (REGISTER_CAST_INT32_TO_INT64): Remove macro. * sysdeps/x86_64/x32/sysdep.h (REGISTER_CAST_INT32_TO_INT64): Likewise.
* lround: provide cast for wordsize-64 version if neededChris Metcalf2015-01-051-0/+4
| | | | | | | | | Platforms with 64-bit registers where 32-bit values need to have the high 32 bits set in a particular way need to have an explicit cast when using the 64-bit sysdeps/ieee754/dbl-64/wordsize-64 version of llround() as lround(). This includes tilegx32, and likely MIPS. x32 does not need this, and AArch64 ILP32 will not either. Require it to be specified in sysdep.h to be explicit.

* Compile s_llround.c with -Wno-error for x32 buildH.J. Lu2014-12-191-0/+6
| | | | | | Since x32 returns 32-bit long int and 64-bit long long int in the same 64-bit register, we make the 32b-bit lround an alias of the 64-bit llround. Add -Wno-error for x32 build to silence the compiler.
* Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers2014-11-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch.

* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-171-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname).

* Remove shlib-versions ABI names support.Joseph Myers2014-06-271-4/+0
| | | | | | | | | | | | | | | | | | | | shlib-versions files can contain ABI lines that map triplets to a canonical ABI name. This name was once used for various purposes where test baseline files for different ABIs went in a single directory; now these purposes use sysdeps files, generation of headers which have per-ABI variants uses abi-variants and related Makefile variables and the shlib-versions ABI names are unused. This patch duly removes those lines and associated build system support for them. Tested for x86_64 (both a full testsuite run and confirming the installed shared libraries are unchanged by the patch). * Makeconfig ($(common-objpfx)soversions.mk): Do not generate abi-name definition. * scripts/soversions.awk: Do not handle or generate ABI lines. * shlib-versions: Remove ABI entries. * sysdeps/powerpc/nofpu/shlib-versions: Remove file. * sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.
