* nptl: Fix libpthread build when UCLIBC_LINUX_SPECIFIC is disabledCarmelo Amoroso2010-09-201-1/+1
| | | | | | | | | | | | | | | | | 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>

* syscall: unify common syscall definesMike Frysinger2009-07-081-0/+1
| | | | | | | | | Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | However, retesting on m68k showed up a problem that had appeared in uClibc since the last time I tried. Specifically, revision 15785 did: -#define HEAP_GRANULARITY (sizeof (HEAP_GRANULARITY_TYPE)) +#define HEAP_GRANULARITY (__alignof__ (HEAP_GRANULARITY_TYPE)) -#define MALLOC_ALIGNMENT (sizeof (double)) +#define MALLOC_ALIGNMENT (__alignof__ (double)) The problem is that (a) MALLOC_HEADER_SIZE == MALLOC_ALIGNMENT (b) the header contains a size value of type size_t (c) sizeof (size_t) is 4 on m68k, but... (d) __alignof__ (double) is only 2 (the largest alignment used on m68k) So we only allocate 2 bytes for the 4-byte header, and the least significant 2 bytes of the size are in the user's area rather than the header. The patch below fixes that problem by redefining MALLOC_HEADER_SIZE to: MAX (MALLOC_ALIGNMENT, sizeof (size_t)) (but without the help of the MAX macro ;)). However, we really would like to have word alignment on Coldfire. It makes a big performance difference, and because we have to allocate a 4-byte header anyway, what wastage there is will be confined to the end of the allocated block. Any wastage will also be limited to 2 bytes per allocation compared to the current alignment. I've therefore used the __aligned__ type attribute to create a double type that has at least sizeof (size_t) bytes of alignment. I've introduced a new __attribute_aligned__ macro for this. It might seem silly protecting against old or non-GNU compilers here, but the extra alignment is only an optimisation, and having the macro is more in the spirit of the other attribute code.
