| | | | | | | | | libc when one of the source files changes. Since there are more places which want to depend on $(libc), fix them all to use a new variable $(libc.depend), which contains the filename for which we have a rule.

| | | | | | | | | | | | | | | 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.
* A patch from our Blackfin repository, originally from Mike Frysinger.Bernd Schmidt2008-01-181-1/+2
| | | | | Add sysdeps/linux/$(TARGET_ARCH) to the list of includes. Needed by some of the Blackfin specific string assembly files.
* A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt2008-01-171-0/+18
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.
