2009-07-20sync a few headers with glibc (no functional changes)Mike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-08syscall: unify common syscall definesMike Frysinger
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.
2007-01-29- sync with glibc (and provide a check for icc).Bernhard Reutner-Fischer
Only affects gcc <2.7 or non-gcc compilers that bailed earlier due to missing int64_t
2006-12-08Take Mike Frysinger's comments into account -- make certain that userEric Andersen
applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file.
2006-12-08Sorry psm but contrary to commit 12927, kernel provided syscallsEric Andersen
are NOT suitable for user-space. The libc ones are the ones that application code must use. If a problem is found with the libc ones, then the libc syscall macros should be fixed.

sys/syscall.h uses the IS_IN_libc define before including any header that includes libc-internal.h (where IS_IN_libc is defined). This patch makes sys/syscall.h include features.h to get the IS_IN_libc define where appropriate.
