| | | | | | | | | | 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.

* Fix two more cases where a libc_hidden_proto was added to string.h whileBernd Schmidt2008-06-112-0/+2
| | | | no libc_hidden_def exists for the function.
* This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt2008-06-043-3/+0
| | | | | | | | | | | | | 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>.

| | | | | | | | | | | | | | | The attached patch adds support for compiling arm uClibc as pure Thumb code. This is needed because some recent ARM codes do not implement traditional ARM mode. Specifically: * Cortex-M1 - An extremely minimal FPGA based core that only implements Thumb-1 (aka ARMv6-M). * Cortex-M3 - A Thumb-2 only ARMv7-M core. Most of uClibc already builds in Thumb mode, all that is left are a handful of assembly bits. Tested on arm-uclinuxeabi.

* Use HIDDEN_JUMPTARGET define instead of __GI_ directly in AVR32 filesHans-Christian Egtvedt2008-02-202-2/+2

| | | | | | | | | | | | | | | | | | The following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica.
