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>
2009-07-05Provide token prototypes for functions that are external but have no headerRon

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>
2009-06-28Add 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.

2008-12-01fix sigset_t size for mips (it's the only arch with 128 signals).Denis Vlasenko
fix _NSIG for it. better document what's going on in sigaction(). seems to not induce any actual code changes (sans mips).
2008-11-25- Fix thumb2 PIE (Joseph S. Myers)Bernhard Reutner-Fischer
This patch fixes position-independent executables (PIEs) for Thumb-2. In Thumb assembly, instructions reading pc give a value 4 greater than the address of the instruction, rather than 8 greater as in ARM mode, so the offset to the GOT needs to have the right offset. (The Thumb-1 code already gets this right; it's the code shared by ARM and Thumb-2 that needs fixing.)

2008-05-19Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL blockDenis Vlasenko

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.
2008-01-17A 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.

The patch below tweaks the ARM nommu startup code so that doubleword stack alignment is preserved. This is required on EABI targets.
