2014-11-19Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar1-0/+2
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. (CPPFLAGS): Use $(in-module). * Makerules: Don't suffix routine names for nonlib. * include/libc-modules.h: New file. * include/libc-symbols.h: Include libc-modules.h (IS_IN): New macro to replace IS_IN_* macros. * elf/Makefile: Set libof-* for each routine. * elf/rtld-Rules: Likewise. * extra-modules.mk: Likewise. * iconv/Makefile: Likewise. * iconvdata/Makefile: Likewise. * locale/Makefile: Likewise. * malloc/Makefile: Likewise. * nss/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile: Likewise. * sysdeps/unix/sysv/linux/Makefile: Likewise. * sysdeps/s390/s390-64/Makefile: Likewise. * nscd/Makefile: Set libof-* for each routine. Set CFLAGS and CPPFLAGS for nscd instead of nonlib.
2014-09-12Add new Linux 3.16 constants to netinet/udp.h.Joseph Myers1-0/+4
This patch adds the new constants UDP_NO_CHECK6_TX and UDP_NO_CHECK6_RX from Linux 3.16 to sysdeps/gnu/netinet/udp.h. (I believe the existing constants there are already Linux-specific, possibly with the intention that other OSes should adopt the same values if possible if adopting the features in question.) Tested on x86_64. * sysdeps/gnu/netinet/udp.h (UDP_NO_CHECK6_TX): New macro. (UDP_NO_CHECK6_RX): Likewise.
2014-07-17Refactor handling of /lib64 etc. cases, move out of sysdeps/gnu/configure.ac.Joseph Myers2-44/+13
This patch continues removing architecture-specific cases from non-architecture-specific files by moving the logic to use directories such as /lib64 out of sysdeps/gnu/configure.ac. A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure scripts can use to declare the library directories to be used; the logic was previously duplicated in configure fragments for aarch64, mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is used directly in sysdeps/gnu/configure.ac only to provide the /lib default (the logic saying that with --prefix=/usr shared libraries go in /lib not /usr/lib); the architecture cases formerly there are moved into various new or existing configure.ac files. The new macro is also used in the various architecture fragments that already had such logic. In the x32 there was previously a configure fragment, but it was a directly written one without a .ac file; now a .ac file is used there instead to generate configure. Tested x86_64 that the installed shared libraries, and the directory structure of the installation, are unchanged by this patch. There is an old bug report - bug 6441 - about library directories changing after reconfiguring. If this is still applicable - and I haven't attempted to confirm it or review the old patch pointed to in that bug - then this patch should reduce the number of places needing changing in any fix. * aclocal.m4 (LIBC_SLIBDIR_RTLDDIR): New macro. * sysdeps/gnu/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. Remove cases for individual architectures. * sysdeps/gnu/configure: Regenerated. * sysdeps/unix/sysv/linux/aarch64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/aarch64/configure: Regenerated. * sysdeps/unix/sysv/linux/mips/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/mips/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * sysdeps/unix/sysv/linux/s390/s390-64/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/s390-64/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/x32/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/x32/configure: Generate.

2014-02-12Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers1-2/+2
This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)
