2008-12-17fix for build failures resulting from "string ops for i386" changeDenis Vlasenko
2008-12-17since gcc -Os hates us and does not inline string ops,Denis Vlasenko
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.

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.
