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 | - see if defined foo before trying to look at the value of foo (that should ↵ | Bernhard Reutner-Fischer | |
be 0 in this case. Avoids some warnings). | |||

2006-12-08 | Take Mike Frysinger's comments into account -- make certain that user | Eric Andersen | |
applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file. | |||
2006-12-08 | Sorry psm but contrary to commit 12927, kernel provided syscalls | Eric 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. | |||

2006-12-07 | Major cleanup of internal mutex locking. Be more consistant in how we do | Eric Andersen | |
things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking. | |||
