2010-09-20nptl: Fix libpthread build when UCLIBC_LINUX_SPECIFIC is disabledCarmelo Amoroso
NPTL library needs both madvise and statfs symbols, that are guarded by UCLIBC_LINUX_SPECIFIC option. This fix provides these symbols too when NPTL is used, indipendently by UCLIBC_LINUX_SPECIFIC choice. Otherwise libpthread link fails as below: LD libpthread-0.9.32-git.so libpthread/nptl/libpthread_so.a(pthread_create.oS): In function `__free_tcb': pthread_create.c:(.text+0x1184): undefined reference to `madvise' libpthread/nptl/libpthread_so.a(sem_open.oS): In function `__where_is_shmfs': sem_open.c:(.text+0x764): undefined reference to `statfs' collect2: ld returned 1 exit status make: *** [lib/libpthread.so] Error 1 Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-08-31libc: Provide both getpgid and __getpgid symbolsCarmelo Amoroso
Indeed unistd.h header does export '__getpgid' by default, while uClibc provide only 'getpgid' implementation. The 'getpgid' symbol is exported by standard header if __USE_XOPEN_EXTENDED is defined. This patch alignes uClibc implementation with standard header (matching with glibc behaviour). Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-07-27new helper funcs for alloca/malloc with mmu/nommuMike Frysinger
The rpc rcmd code has some ugly ifdef mazes to handle mmu/nommu differences just to select alloca or malloc. Unify those with some helper macros in a new header, and then convert the rcmd code over to it. This is all geared towards fixing the getdents helper functions which only use alloca() atm. Now that we have helper functions, convert the getdents functions over too. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Steven J. Magnani <steve@digidescorp.com>

2010-04-22nptl: fix libc internal, dynamically enabled lockingTimo Teräs
Final iteration to fix libc internal locking if libpthread is pulled in by dlopen call (directly or indirectly). We cannot really use the weak symbol trick for shared build, since the symbols won't get refreshed if libpthread is pulled in dynamically. In glibc, they have #ifdef SHARED magic to either use pthread_functions table, or weaks. But as we shared object files with both builds, this does not sounds good either. The reintroduces the libc weaks.c, but uses them now only with static build. For dynamic build, we still use the symbols with same name, but provide weaks in forward.c so they end up dereferencing the pthread_functions table indirectly if we are not linked to libpthread. Mutex initialization is hard coded as inline, as it needs to happen even if libpthread is not initially loaded.

2010-04-20nptl: remove unneeded libc-lock.h includeTimo Teräs
I semi-accidentally added include for libc-lock.h because the intention was to use locking macroes from there. However, we ended up using using the weak alias stuff. This is additionally good since now this can result in compile errors like: In file included from /toolchain/include/bits/uClibc_mutex.h:16, from /toolchain/include/bits/uClibc_stdio.h:107, from /toolchain/include/stdio.h:72, from /work/freetype-2.3.11/include/freetype/config/ftstdlib.h:100, from ./builds/unix/ftconfig.h:43, from builds/unix/ftsystem.c:21: /toolchain/include/bits/libc-lock.h:309: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void' Remove the unneeded include causing breakage.

2010-04-16libc: remove libc weak __pthreads_* wrappersTimo Teras
It is not possible to override for libpthread to override the weak libc definitions. This has never worked in uclibc, and does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK). The proper thing to do is have weak prototypes in libc, and definitions in libpthread only. This way libc runs even if those functions are not defined, but just needs to protect against the NULL values (done by implementing __uclibc_maybe_call). This fix the problems if libc is linked before libpthread or if libpthread is pulled by a dependency library.

2010-04-15nptl: fix libc sigtimedwaitTimo Teräs
It seems that 57e8823548ad6e65d33b2153edeb18fb0edc20e6 removed completely sigtimedwait symbol from libc which is wrong. I hope there is not too many other things like this. Apparently the libc_hidden_* macros actually make previously hidden symbols visible globally (creates alias from __GI_* to *). This is probably ancient confusion from times when gcc did not support visibility attribute and hiding symbols was done using hacks like this. This also adds attribute_hidden to the internal __sigtimedwait for nptl case. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2010-02-09nptl: sysdep headers re-factoringCarmelo Amoroso
This patch will re-factor and simplify sysdep headers handling for nptl branch. The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available only into nptl branch because are defined in sysdep.h header under the nptl folder even if they are not related to NPTL at all (this was likely due to a bad choice done at the early stage of NPTL porting). This is a required steps for integrating into master branch some asm code available in nptl branch for sh4. The main changes are described below: nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h nptl/sysdeps/sh/sysdep.h ---------------------| nptl/sysdeps/unix/sh/sysdep.h ----------------| nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----| nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -| |(merged) ---> libc/sysdeps/linux/sh nptl/sysdeps/unix/sysdep.h (deleted) Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.

Thanks, indeed. If we came into "#elif WORDSIZE == 32" block, above condition never be true. So we can just move this statement out of "#if...#elif...#elif...#endif" block. Here is a revised patch. ------------------------------------------------------ From: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Subject: [PATCH] getdents: Fix mips64 build Some archs (such as mips64) do not have getdents64 syscall but have getdents syscall. Define alias for it. This fixes regression from 0.9.30.1. Backgrounds: This is once done by commit e8b1c674. But after the commit 33bcf733 ("Use getdents syscall if kernel provide supports for this instead of relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined the alias for getdents64 is not defined. The macro __ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1 but the commit 0f0f20ab ("Move kernel-features.h header from the linuxthread directory to a common one...") really enables it.
