2011-02-21bfin: add support for new cacheflush syscallSteve Kilbane
Newer gcc's will generate a call to cacheflush when updating jump tables, and that has to be done in kernel space (to avoid hardware anomalies). So make sure uClibc provides that symbol. Signed-off-by: Steve Kilbane <steve@whitecrow.demon.co.uk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-21bfin: fix sram/dma syscall definitionsSteve Kilbane
Once we pull in the header, we're forced to declare the syscall with all the right types. Signed-off-by: Steve Kilbane <steve@whitecrow.demon.co.uk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-21bfin: add missing GNU-stack markings to __longjmpMike Frysinger

2009-11-23bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger
Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-07clean up O_CLOEXEC handlingMike Frysinger
Drop the "#ifndef O_CLOEXEC" cruft, enable O_CLOEXEC in most fcntl.h headers, and import __ASSUME_O_CLOEXEC from glibc. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-07fcntl.h: drop unused/dead O_STREAMINGMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-29build: Include Makefile.commonarch from common Makefile.inCarmelo Amoroso
Avoid including akefile.commonarch in each Makefile.arch. Include it instead from Makefile.in just after the arch specific Makefile.arch Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2009-07-26enable nanosecond stat support for everyoneMike Frysinger
Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-23Blackfin: fix typo in byteswap.h commitMike Frysinger
The Blackfin port hasn't been compiling cleanly, so this typo was missed in the byteswap unification commit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-23Blackfin: fix incorrect attribute orderMike Frysinger
The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself. In file included from ldso/ldso/ldso.c:43: ldso/ldso/bfin/elfinterp.c: At top level: ldso/ldso/bfin/elfinterp.c:42: warning: '__visibility__' attribute ignored on non-class types In file included from ldso/ldso/bfin/elfinterp.c:341, from ldso/ldso/ldso.c:43: libc/sysdeps/linux/bfin/crtreloc.c: At top level: libc/sysdeps/linux/bfin/crtreloc.c:91: warning: 'visibility' attribute ignored on non-class types Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-23create real common vfork() functionMike Frysinger
Rather than force people to always implement their own vfork(), have the default implementation be sane. For now, only the Blackfin port uses the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-22Blackfin: no need to load P5 for shared FLATJie Zhang
The register is already loaded for us upon entry by the kernel. Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-21byteswap: unify common definitionsMike Frysinger
The majority of the byteswap functions are the same across all arches, so setup a common header to provide definitions if they don't exist. This allows arches to override only the ones they actually want to implement with inline assembly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-09syscall(): create a common version based on INLINE_SYSCALL_NCS()Mike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-09syscall: unify part 2: NCS varietyMike Frysinger
Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-08syscall: unify common syscall definesMike Frysinger
Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-03uClibc_arch_features: sync defines between portsMike Frysinger

2008-01-18L1 memory support for the Blackfin. A couple new syscalls to manage L1Bernd Schmidt
allocations, dma_memcpy to move stuff between L1 and main memory, and a new structure to describe the global data in L1 scratchpad memory.
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.
2008-01-08change NO_UNDERSCORES to just UNDERSCORES so as to be less confusing when ↵Mike Frysinger

2007-11-23From Jie Zhang:Bernd Schmidt
__bswap_16 could not assume that it's zero extended when an unsigned short int is loaded into the data register.
