2003-05-01setjmp was trashing r12 which is bad and can cause apps to crash if they areDavid McCullough
using r12. r12 is supposed to be preserved across C function calls. r0-r7 are trashable :-)
2003-03-07Patch from Stefan Allius:Eric Andersen
fix a couple of gcc 3.3 compiler warnings in gmon.c
2003-03-06Patch from Stefan Allius to finish off the last required bitsEric Andersen
for gmon profiling support for the SuperH target.
2003-03-03Initial effort at adding profiling support.Eric Andersen
2003-02-17If floating point was enabled, setjmp would write to memory well past theDavid McCullough
end of the buffer.
2003-01-24Ok, people are probably going to hate me for this... This commit changes theEric Andersen
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
2003-01-23Update architecture specific support to consistantlyEric Andersen
generate a crt0 and crt1 file. Most arches still need to be updated to call __uClibc_start_main() rather than __uClibc_main().
2002-12-12Based on discussions with Stefan Allius, change it so that we alwaysEric Andersen
build a crt0.o and a crt1.o. crt1.o will support ctors and dtors if such support is enabled. One more gratuitous toolchain support issue is thereby removed... -Erik
2002-11-29Silly me, I forgot to include features.hEric Andersen
2002-11-27Make support for global constructors and global destructors beEric Andersen
configurable, so people who do not need or want ctor/dtor support can disable it and make their binaries a little bit smaller. -Erik

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

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
2002-11-04I dunno why there were align 5, but align 4 is much more sensible.Eric Andersen
2002-11-04Kill sysdep.h and fixup the SH asm to not use it.Eric Andersen

2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
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

2002-10-01Patch from Stefan Allius <allius@atecom.com>:Eric Andersen
----------------------------------- In extra/Configs/Config.sh I added the INCLUDE_PTHREADS statement and change the default values for BUILD_UCLIBC_LDSO and HAVE_SHARED. ----------------------------------- In extra/scripts/initfini.pl My last patch removes two labels, which migth be used by the .size statements. (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. -----------------------------------
2002-10-01This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen
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.
2002-09-05Change <bits/syscall.h> to <bits/sysnum.h>.Miles Bader
2002-08-27Somehow the bit of code that add the offset of envp to argv got lostDavid McCullough
and envp was a very small number and not an address. I think this fixes most of the SH platform.
2002-08-27Fix a delay slot problem, this gets some apps working on SH, a good numberDavid McCullough
are still seg-faulting.
2002-08-27Added __kernel_fsid_t to satisfy some apps that need it.David McCullough
Definitions taken from 2.4 kernel sources for each of the platforms.
2002-08-26Make bits/kernel_types.h include guard names match the includeEric Andersen
guard names used by the kernel's asm/posix_types.h to eliminate gratuitous conflicts and let our file win over the very-likely- to-be-broken kernel header file. -Erik
2002-08-25Finish off the bits/kernel_stat.h cleanup for properEric Andersen
__USE_FILE_OFFSET64 handling. -Erik
2002-08-24Break dependancy of bits/types.h on the asm/posix_types.h kernelEric Andersen
header, which is not directly usable for many architectures. -Erik
2002-08-23Split out the definition of struct stat into the new archEric Andersen
specific bits/kernel_stat.h file. -Erik
2002-08-19Work from Stefan Allius which allows superH to use the commonEric Andersen
method for building crti.o and crtn.o
2002-08-09Fix a number of compile time warnings so that uClibc will build with -Werror ↵David McCullough
using a 3.0.4 version of the sh-linux-gcc compiler.
2002-08-09Doh! I broke it. oops. Patch from Stefan Allius to fix it.Eric Andersen
2002-08-08I reworked syscalls.h to match how I'm doing other arches. Stefan Allius andEric Andersen
Edie C. Dost has some concerns about the perl script used to general crti.o and crtn.o and added their own versions. These versions will win since they are built last,
2002-07-22Rework syscall handling. Rewrite syscall handlers for x86 and ARM.Eric Andersen
Prepare to kill the UNIFIED_SYSCALL option and instead have it be a per arch thing that is either enabled or not for that arch. -Erik
2002-04-14Manuel and I were looking into a problem with applications failing to linkEric Andersen
(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
2002-04-03Run dos2unix on these filesEric Andersen
2002-03-13Build our own crti.o and crtn.o with a cross arch method that IEric Andersen
can live with much better the what glibc does. -Erik
2002-03-02Remove generated stuff, restore sh/sys/procfs.h from M. R. BrownEric Andersen
2002-03-01Move syscall.h generation to the top level MakefileEric Andersen
-Erik
2002-03-01Patch from M. R. Brown <mrbrown@0xd6.org> to fix pthread supportEric Andersen
for SH, and fix vfork
2002-03-01Major rework of the include files to eliminate redundancyEric Andersen
and to better support each arch. This is a really big patch... -Erik
2002-02-13A number of naming updates in preparation for adding inEric Andersen
proper threading. Most of this is from Stefan Soucek, with additions and changes as needed from me.
2002-01-17Add sbrk and friendsDavid McCullough
Fix bug in setjmp (jmpbuf changed size)
2002-01-07Mahe 'make clean' remove generated bits/syscall.h, asEric Andersen
noted by "Kim B. Heino" <Kim.Heino@bluegiga.com> -Erik
2002-01-02Fixes from M. R. Brown <mrbrown@0xd6.org> to fixup some littleEric Andersen
compile nits with the SH architecture, and support SH4,
2002-01-02Oops. Disable threading.Eric Andersen
-Erik
2002-01-02Sync SH header files with glibc 2.2.4, so it can actually have a chanceEric Andersen
(at least in theory) of working. -Erik
2001-11-14Scrub up some lingering problems preventing readdir64 from workingEric Andersen
and creating several *64 problems, particualrly when client apps used -D_FILE_OFFSET_BITS=64 -D__USE_FILE_OFFSET64. All better now. -Erik
2001-10-04Patch from David McCullough <davidm@lineo.com>:Eric Andersen
* reduce the sigset types to 32 bits (I've mentioned this before) I think I saw this change go in for another platform anyway ;-) * Do not use _IO_FILE as it clashes with the C++ libraries which know too much about how glibc workds :-( * Do not use _G_va_list for the same reason. * remove the CTORS/DTORS from crt0.S for ARM as the compiler provided crtbegin.o and crtend.o have these (and only these) already in them and you get multiple defined errs :-(
2001-08-06Fixup the pipe system call for the SH target.David McCullough
The FD's are returned in registers.
