We use the compiler-driver and not ld.
2008-01-17A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt
a problem where the linker was trying to use the wrong symbol name for the init function. Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960, microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets which define SYMBOL_PREFIX as _. Remove defines and undefs from uClibc_arch_features.h of each target. Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.

__dns_lookup(). This avoids segmentation faults when more than 1024 file descriptors are used by an application.

MontaVista noticed that when their kernels were configured to trap on unaligned access gethostbyname_r could mysteriously crash. I tracked this down to an unaligned buffer being passed to gethostbyname_r from some other part of uClibc (afraid I don't remember where from any more). We have to pad the beginning of the buffer to a pointer alignment before we store pointers in it.

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.

I noticed, that in libc/misc/syslog/syslog.c when the syslog socket is opened, the close-on-exec flag is not set, as it is in gnu libc. This enables that behavior.

2008-01-05michael_d writes in 1879:Mike Frysinger
When no TIOCGPTN definition is present in the kernel headers, the library's ptsname() function will not work. The libc/stdlib/ptsname_r.c file is the problem. This file includes a complicated nest of #if directives. One of these #if's has the opposite sense from what is required.

2008-01-05michael_d writes in #1874: Mike Frysinger
On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

2007-12-03realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).Denis Vlasenko
reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).

Jean-Christian de Rivaz writes: The attached patch solve an issue I faced while using the libdbus-glib waiting for a D-Bus message or the end of a glib timer at the same time. This specific case of use generate a poll call with a zero timeout. On platformes with the glibc a zero timeout poll return immetiately even if there is no file descriptor event. But on platformes with uClibc a zero timeout poll block until a file descriptor event occurs.
