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.

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.

Here is a small patch to add epoll support to uclibc. The only thing I am not sure about is what needs to be done (if anything) to make it work on 2.4/2.2 kernels (are the syscall numbers defined but give errors when called or not?). Tested on 2.6, though some other issues prevent more extensive testing at the minute. Mike Frysinger: cleaned up patch and added checks to make sure that the syscall actually exists, returning ENOSYS in cases where it doesn't.

2004-10-31Revert Peter's __lib_gettimeofday patch. There's the minor issue ofManuel Novoa III
adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition.

Hello! Would the attached patch be acceptable (maybe instead of __libc_gettimeofday using __gettimeofday) We have some issues, see http://bugs.gentoo.org/show_bug.cgi?id=65892
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik
