* Add a syscall() implementation using a hacked version of the syscall6 macro.Manuel Novoa III2003-12-022-1/+26
| | | | Untested, but syscall() is needed by busybox for pivot_root at least.
* Remove SAFECFLAGS. It was a workaround for failures in old awk scriptEric Andersen2003-11-221-11/+3
| | | | | | | | | | used to generate the crti.S and crtn.S files. Since we don't use that anymore, keeping the workaround makes no sense. Furthermore, in most cases, SAFECFLAGS was not picking up all the needed flags, causing crti.o and crtn.o to not be built PIC. Which is very bad. Removing SAFECFLAGS and using CFLAGS fixes that as well.

| | | | | | | | | | Hello Erik, to compile the new uClibc release for a SH3 we need some little modifications: First I fix the crt[in].S files, so we can use them for big endian and little endian targets.
* Darn. Fix compilation for soft-float, which I inadvertantlyEric Andersen2003-11-081-4/+7

| | | | | | | | | | ln.patch: * Define $(LN) as ln in Rules.mak. * Change all occurrences of ln into $(LN). * Change all constructs like (cd path && ln -sf foo/file file) into $(LN) -sf foo/file path/file. The latter construct is already used in a number of places so it should not be an additional compatibility problem.

* Patch from Atsushi Nemoto (with some additions):Eric Andersen2003-10-082-0/+57
| | | | | | | Current uClibc contains only one fpu_control.h and it is i386 version. This is a patch to use platform specific fpu_control.h. All new files come from glibc 2.3.2. This patch is against 0.9.21 but also can be applied to CVS as is.

| | | | | | | | | | | | | | | type of 'struct stat' and 'struct stat64' so they use consistant types. This change is the result of a bug I found while trying to use GNU tar. The problem was caused by our using kernel types within struct stat and trying to directly compare these values with standard types. Trying an 'if (a < b)' when 'a' is an 'unsigned long' and 'b' is an 'int' leads to very different results then when comparing entities of the same type (i.e. time_t values).... Grumble. Nasty stuff, but I'm glad I got this out of the way now. As a result of this fix, uClibc 0.9.17 will not be binary compatible with earlier releases. I have always warned people this can and will happen. -Erik

* Stefan Allius writes:Eric Andersen2002-11-153-115/+116
| | | | | | | | | | | I attached a patch, which revise the clone.S and vfork.S: - Use PIC code. - include new file syscall.S, so we can simply make a branch to __syscall_error instead of a PLT/GOT call - call errno_location to store the syscall error (for pthreads) - avoid to use the 'shad' statement on SH2 targets - call fork if vfork isn't available - some cleanups and optimization

* Stefan Allius writes:Eric Andersen2002-11-153-11/+78
| | | | | | | | | | | | | Hi Erik, I added the FPU support for the setjmp/longjmp stuff. This patch also moves the code from the bsd*.S files to the setjmp.S file, so we can use simple branch instructions instead of referencing over the .GOT/.PLT section. This makes the PIC code much easier, smaller and faster. (The idea comes from the SPARC target) Bye Stefan

| | | | | | | | | | | | | | | been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik

(Sorry, but I'm a perl beginner) I fixed it. ----------------------------------- In libc/sysdeps/linux/common/initfini.c I fixed two warnings "nested extern declaration of `i_am_not_a_leaf.. ----------------------------------- In libc/sysdeps/linux/sh/__init_brl.c brk.c sbrk.c I fixed some compiler warnings which comes from a wrong inclusion order. -----------------------------------
* This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen2002-10-011-19/+30
| | | | | | | how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.

* Somehow the bit of code that add the offset of envp to argv got lostDavid McCullough2002-08-271-0/+1

* Manuel and I were looking into a problem with applications failing to linkEric Andersen2002-04-141-0/+7
| | | | | | | | | | (undefined reference to `main') when the .o file containing main was contained in an static library(a '.a' ar archive). It turns out that due to its single pass nature, GNU ld was failing to pull it into the build. This sticks a dummy reference to main() into crt0.o, so that when an application is linked with the main() function in a static library, we can be sure that main() actually gets linked in. -Erik
