2009-07-06sparc: Update syscalls.h to define INTERNAL_SYSCALLAustin Foxley
Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-07-05Avoid type-punned pointers that break strict-aliasingRon
Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Avoid warnings about shifting more bits than we haveRon
The test here is a constant expression and will compile out. For platforms that don't need the shift the code gets slightly smaller and simpler, for those that do the result is unchanged. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Check #if feature test macros are defined where they may not beRon
Once again all of these reduce the noise from gcc-4.4. Replaces a few more (USE_TLS && HAVE___THREAD) with USE___THREAD while we need to mess with them for this anyhow. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Provide token prototypes for functions that are external but have no headerRon
This cuts down on a lot of noise from gcc-4.4 Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-03i386: store errno value before using __set_errno()Ingo van Lil
The __syscall_error() function stores the errno value in the edx register before invoking the __set_errno() macro. When using the pthread library this macro calls thread_self() to determine the errno location, which might clobber the edx register. The errno value must be stored in a "real" variable so the compiler can take care of saving/restoring it if necessary.

2009-07-03uClibc_arch_features: sync defines between portsMike Frysinger
Make sure each arch has the same complete list to make comparing between them easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-01Correct ARM memcpy comments.Joseph Myers
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. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-30Fix Thumb-2 setjmp.Joseph Myers
Many Thumb-2 instructions cannot use sp or pc as operands, and the assembler now diagnoses these. setjmp had one such instruction, movs; this patch changes it to mov. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-30Fix Thumb-2 memcpy.Joseph Myers
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. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-28Add missing CLIBABI variables __aeabi_stdin, __aeabi_stdout, __aeabi_stderr.Joseph Myers
The ARM EABI has a document CLIBABI specifying various __aeabi_* functions and variables to be provided for the use of portable objects that can be linked with different EABI-conforming C libraries. __aeabi_stdin, __aeabi_stdout and __aeabi_stderr were missing in uClibc; this patch (originally from Nathan Froyd and for glibc) adds them. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-28wchar: fix inverted parameters in error messageAndré Goddard Rosa
The error message should output "fromcode -> tocode" rather than "tocode -> fromcode". Seems to be a typo due to the order of the func called: iconv_t iconv_open(const char *tocode, const char *fromcode); Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-28libc.so: include all output formats in linker scriptSteve Bennett
Rather than ripping out the default output format from the linker, include the big/little endian alternatives for the people who link with bi-endian toolchains. URL: http://lists.uclibc.org/pipermail/uclibc/2009-June/042595.html Signed-off-by: Steve Bennett <steveb@workware.net.au> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-05-27waitid: linux ABI takes 5 args, not 4Mike Frysinger
The POSIX waitid() takes 4 args, but the Linux one takes 5 args, so make sure we stuff the 5th arg with a NULL. Otherwise garbage gets randomly passed up and considering this is a pointer, that's baaaad. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-05-05Add position independent code for crt1.S.Carmelo Amoroso
This will generate a Scrt1.o that is linked to executabled when compiled as PIE code (position independent executable) without requiring relocation in .text section (not allowed on uclibc/sh4).

2009-04-23libc/string/i386/memset.c: memset 1 byte at a time is a bit grossDenis Vlasenko
2009-04-18libc/inet/resolv.c:Denis Vlasenko
Collapse __length_dotted into __length_question (the sole user of it). Make __length_question and __decode_answer static, they are used only once by only one function. Delete __decode_question, it is unused. All in all, four less .o files in libc.a. Document what __dns_lookup returns (length of the packet). Propagate packet len into __decode_answer, __length_question, __decode_dotted and check that we do not use data past the end of the packet. Rename some variables/parameters to better names (len -> packet_len, data -> packet etc). Add mini-doc how DNS packets look like. Style cleanup.

2009-03-25- Add strtouq alias (to strtoul) for 64bitBernhard Reutner-Fischer
The strtouq alias was only available on 32bit, breaking compilation of stuff using strtouq on 64bit machines. At the same time use the correct return type (u_quad_t). Signed-of-by: Peter Korsgaard <jacmet@sunsite.dk>
