The comments on register usage in ARM memcpy had dest and src the
wrong way round; this patch (originally from Mark Shinwell) corrects
this and adds a note on the return value.

When an IT block was changed from having two instructions to having
one, the IT instruction at the start of the block was not updated,
causing memcpy to fail to assemble for Thumb-2; this patch makes the
obvious fix.

is always equivalent to __UCLIBC_CURLOCALE->x.
remove typedef __uclibc_locale_t, it used only in a few places,
it is lees confusing to use struct __uclibc_locale_struct
everywhere.
xlocale.h: hide __global_locale back under _LIBC,
bug 53 is wrong in claiming it should be exported.
Also hide under _LIBC:
extern __locale_t __curlocale_var;
extern __locale_t __curlocale(void);
extern __locale_t __curlocale_set(__locale_t newloc);
# define __UCLIBC_CURLOCALE
# define __XL_NPP(N)
# define __LOCALE_PARAM
# define __LOCALE_ARG
# define __LOCALE_PTR

implement inline versions of some of them.
Enable only those which result roughly in the same
code size as using out-or-line versions.
None of this affects users, installed headers won't have
any trace of it.

no libc_hidden_def exists for the function.
|
|
The obsolete functions bcopy, index, etc. are not supposed to be used within
uClibc itself. Hence, there is no libc_hidden_def for them, but the previous
patch did not just move libc_hidden_protos, it also added new ones for the
legacy functions. As a result, programs which use these functions can no
longer link with uClibc.
This fixes it by removing the unnecessary libc_hidden_protos. I've also
removed all inclusions of <strings.h> from uClibc source files: since we
define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not
need to duplicate the libc_hidden_proto block in <strings.h>.
