Rework crt bootstrap to work with the new __uClibc_main(), and hardwire crt init/fini code since the awk approach to generating it on the fly doesn't work for microblaze.

2010-10-27Fix msync() redefinition for noMMU buildBernhard Reutner-Fischer
An architecture that _may_ have a MMU (and thus implements the msync syscall), but for which the kernel and uClibc are built as noMMU, we have a stub for msync. Thanks to Steven J. Magnani for noticing. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-10-27mips: fix errno setting after syscallAlexander Gordeev
If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

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>
