Looks a bit like we wouldn't need to calculate the carry flag there?

2008-09-26Rebased the memcpy() and memset() implementations for CRIS on the versionsPeter Kjellerstedt
found in newlib rather than the ones found in glibc. This should make them smaller and (hopefully) make them compile with newer versions of gcc.

__UCLIBC_HAS_LOCALE__ macro but it does not include <features.h>, so that macro is never defined. This causes problems with strcoll when locale support is enabled.

2008-06-11Fix two more cases where a libc_hidden_proto was added to string.h whileBernd Schmidt
no libc_hidden_def exists for the function.
2008-06-04This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt
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>.

2008-04-15amd64 string ops: replace some instructions by smaller ones,Denis Vlasenko
e.g. testb $0xff, %cl -> testb %cl, %cl
2008-03-26Paul Brook writes:Bernhard Reutner-Fischer
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.
2008-03-13avr32: Use HIDDEN_JUMPTARGET() macro in bzero.SHaavard Skinnemoen
Also, remove the hidden __memset symbol from memset.S
2008-03-13From: Geoffrey Wossum <geoffrey@pager.net>Haavard Skinnemoen
Found a problem with the AVR32 optimized bzero() code. Due to a missing #include, it actually generated no code.
2008-02-20Use HIDDEN_JUMPTARGET define instead of __GI_ directly in AVR32 filesHans-Christian Egtvedt
This patch uses the HIDDEN_JUMPTARGET instead of the __GI_ prefix in AVR32 assembler files. This is done to follow the code style in uClibc. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
2008-01-09add workaround for gcc-3.4.6 with mipsMike Frysinger
2008-01-05Chris Zankel writes:Mike Frysinger
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. For more information, please visit: www.linux-xtensa.org.

2007-09-15pull from Blackfin repo: cleanup string funcsMike Frysinger
2007-09-15Blue Swirl writes:Mike Frysinger
I got the library to compile with the attached patches, though dynamic loader crashes early. In buildroot I changed the architecture name by hand from sparc to sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit) instructions. This configuration is not supported by QEMU, so I aimed for pure 64-bit. I think Sparc64 option needs to be added to buildroot. The _Qp_ ops seem to be required by the ABI. This and setjmp patches are just hacks to get the compilation further. The _Qp_ ops can be found in glibc, would it be OK to use those? V9 assembler requires declarations for global register use. The mem* functions in sparc32 directory did not work. They are actually used only by the hybrid 32-bit + V9 CPU configuration.

2007-03-11Patch from Al Stone to fix ia64:Rob Landley
The attached patch works around some compilation failures on ia64 caused by the use of the C preprocessor ## operator, and allows the ia64 default configuration to build again -- or, at least get as far as an x86 build does (the current source tree has some problems compiling because of conflicting type declarations for __kernel_dev_t).

Import mips64 version of memset, memcpy from glibc.
2006-10-19Make strdup() use memcpy() rather than strcpy() to duplicate the string. Peter Kjellerstedt
The rationale is that we already have the length of the string to duplicate (from doing the malloc()), and memcpy() should then always be faster than strcpy() (or at least as fast).
