* Blackfin: fix incorrect attribute orderMike Frysinger2009-07-232-2/+3
| | | | | | | | | | | | | | | | | 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>
* Blackfin: add elf_machine_load_address() stubMike Frysinger2009-07-231-0/+8
| | | | | | | | | | | The Blackfin port never defined elf_machine_load_address() because the one place this code is called never matters to us. But without it, common code likes to hit a build failure, so stub it out. ldso/ldso/dl-startup.c: In function '_dl_start': ldso/ldso/dl-startup.c:170: warning: implicit declaration of function 'elf_machine_load_address' Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* ldso: fix building for FDPIC systemsMike Frysinger2009-07-231-1/+1
| | | | | | | | | | The force shareable code missed a spot of using the DL_RELOC_ADDR() indirection thus leading to invalid operands: ldso/ldso/ldso.c: In function '_dl_get_ready_to_run': ldso/ldso/ldso.c:409: error: invalid operands to binary + (have 'Elf32_Addr' and 'struct elf32_fdpic_loadaddr') Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* do not install bits/syscalls-common.hMike Frysinger2009-07-231-0/+1
| | | | | | | Since we stub out the installed bits/syscalls.h, the installed bits/syscalls-common.h header is completely useless. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* create real common vfork() functionMike Frysinger2009-07-233-28/+14
| | | | | | | | | 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>

| | | | | | openat64() uses openat(), so we need hidden aliases for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* add hidden aliases for ntoh/hton functionsMike Frysinger2009-07-222-4/+14
| | | | | | | Sometimes references for these functions show up (like when debugging is enabled), so add hidden aliases for them if needed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* linuxthreads.old: fix crash in debug codeMike Frysinger2009-07-211-1/+1
| | | | | | | If pthread_join() is called and there is nothing to join, then the debug code will attempt to dereference a NULL pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* byteswap: unify common definitionsMike Frysinger2009-07-2110-632/+242
| | | | | | | | | 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>
* s/UCLIBC_INTERNAL/_LIBC/gDenys Vlasenko2009-07-2111-24/+16
| | | | | | | | | | Undo my old mistake. I added UCLIBC_INTERNAL define, but later I realized _LIBC is doing exactly the same thing. This change converts all usages of UCLIBC_INTERNAL to _LIBC, removing all instances of UCLIBC_INTERNAL. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* avr32/microblaze/vax: punt local byteswap.hMike Frysinger2009-07-203-175/+0
| | | | | | | These arches are generic C implementations of the byteswap functions, so rather than keep a useless local copy, use the common C one. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* syscall: convert cris/hppa to common syscallsMike Frysinger2009-07-203-140/+19
| | | | | | | The cris/hppa code appears to be easy to convert, so go ahead and do it for them. Build tested only. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* MAKEALL: find kernel headers betterMike Frysinger2009-07-201-1/+12
| | | | | | | Work with pre-sysroot compilers that have kernel headers available in the standard location, and let people force the location manually. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* some ports define ENOTSUPMike Frysinger2009-07-201-1/+3
| | | | | | | A port or two (like hppa) does define ENOTSUP, so don't assume that everyone needs this fallback define. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* INLINE_SYSCALL_NCS: scope out local vars to avoid conflictsMike Frysinger2009-07-201-6/+6
| | | | | | | | | | | The INLINE_SYSCALL_NCS() macro was using "res" and "err" as local variable names, but this caused conflicts with some code (like clock_getres) whose arguments were named the same. libc/sysdeps/linux/common/clock_getres.c: In function 'clock_getres': libc/sysdeps/linux/common/clock_getres.c:15: warning: 'res' is used uninitialized in this function Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* linuxthreads.old: extend workaround for asm rename warningsMike Frysinger2009-07-202-0/+12
| | | | | | | The libc_pthread_init.c needs the include workaround like forward.c, and forward.c needs more includes now. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* fix building for systems w/out ldso supportMike Frysinger2009-07-202-1/+8
| | | | | | | If an arch (like alpha and others) have no ldso support at all, then there is no point in attempting to walk loaded modules in the dl-* helper funcs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* alpha: fix building with no asm/elf.hMike Frysinger2009-07-201-1/+14
| | | | | | | The latest sanitized linux kernel headers no longer export asm/elf.h, so do not rely on it anymore. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* fdatasync: handle latest alpha syscallsMike Frysinger2009-07-201-1/+1
| | | | | | | The latest alpha Linux kernel defines __NR_fdatasync like everyone else and deprecates the older __NR_osf_fdatasync, so support that setup. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* first pass at implementing *at funcsMike Frysinger2009-07-2024-49/+457
| | | | | | | Tested basic functionality with coreutils and things seem to work. At least gives us a basis to jump from. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* dirent: push dirent type to prototypesMike Frysinger2009-07-207-48/+70
| | | | | | | | | | This syncs the dirent related functions with the glibc behavior -- rather than take void pointers everywhere, make the struct dirent pointers explicit in the API. After all, the functions themselves will cast the pointers to a dirent structure, so if it isn't as expected, people will crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* add a wchar.h stubMike Frysinger2009-07-202-0/+19

* note that we do not want hidden malloc aliasesMike Frysinger2009-07-201-0/+2
| | | | | | | | | | We want to let malloc() and friends be overridable at runtime so that apps can insert their own implementation (think debugging, specialized setups, etc...). That means that C library functions that return allocated memory have to go through the normal malloc() symbol as well as the external code is the one who will be calling free().

| | | | | | | | | | Convert the large if...$(RM)...endif style to standard Kbuild foo-$(...) += style to make the list much easier to review and update. This is largely a style change, but in the process, these two headers are added to the "always remove" list: tls.h and uClibc_errno.h Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* use -EB/-EL for all targetsMike Frysinger2009-07-151-8/+3

* Fix ARM syscall argument loading.Joseph Myers2009-07-141-14/+21
| | | | | | | | | | | This patch is a uClibc equivalent of <http://sourceware.org/ml/libc-ports/2008-11/msg00006.html>, to compute all syscall arguments on ARM in temporary variables before loading them into register variables. The principle is as for that glibc patch; the problem I actually observed was a GCC internal compiler error building ld.so for Thumb-2. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
