2003-04-21Fix SIGTRAP handling on arm. The defination of struct ucontext,Eric Andersen
which was copied from glibc, is wrong. So fix it. -Erik
2003-03-06Make profiling on arm workEric Andersen
2003-03-03Initial effort at adding profiling support.Eric Andersen
2003-03-03Fix the double sub #48, should have been an add :-)David McCullough
2003-02-23Fix FP handling alignment problems on ARM platforms without an FPU,David McCullough
patch from Vadim Lebedev <vadim@7chips.com>.
2003-02-08Fixup handling of the .note.ABI-tag section so that it is ARM only,Eric Andersen
and so it actually works as intended allowing binaries on ARM to be debugged. -Erik
2003-01-24Finish up fixing stat and setting various system types.Eric Andersen
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().
2003-01-23Update crt0 for arm to provide the main referenceEric Andersen
a bit more nicely, and make _init and _fini be weak for people with broken compilers -Erik
2003-01-22Update sigaction syscall names to act more like glibc. Fix the x86 sigactionEric Andersen
implementation such that gdb can actually debug signal handlers. Gdb behaves much better now, for example, on multi-threaded apps. -Erik
2003-01-22Add in arm specific sigaction implementation to fix sa_restorerEric Andersen
behavior so it works as expected
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
2002-11-27Make 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
2002-11-15I was an idiot and put _fini into the wrong register. Duh.Eric Andersen
This patch from David Meggy fixes it...
2002-11-06Update soft-float handlingEric Andersen
2002-11-03A patch from Vincent Sanders to fix the arm implementation ofEric Andersen
ioperm() and iopl()
2002-10-09Support O_STREAMINGEric Andersen
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.
2002-09-10Don't run floating point opcodes when code is compiled -msoft-floatEric Andersen
-Erik
2002-09-05Change <bits/syscall.h> to <bits/sysnum.h>.Miles Bader
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
2002-08-22Support _syscall6 and _syscall7 for armEric Andersen
-Erik
2002-07-25Implement syscall() for armEric Andersen
-Erik
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
2002-04-09Create a much more careful ftruncate64 implementation, that shouldEric Andersen
address all the concern Miles had with the earlier versions... -Erik
2002-03-31Add in support for ftruncate64 on both ARM and x86Eric Andersen
-Erik
2002-03-16Remove the C++ support stubs, since these now live elsewhere andEric Andersen
these stubs were preventing the real stuff from working properly. -Erik
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
2002-03-01Move syscall.h generation to the top level MakefileEric Andersen
-Erik
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
2002-01-31Fixup setjmp and longjmp so they behave themselves properly nowEric Andersen
on both x86 and arm... -Erik
2002-01-21Make sbrk common, add arm/brk.c, cleanup leftover damageEric Andersen
2002-01-07Mahe 'make clean' remove generated bits/syscall.h, asEric Andersen
noted by "Kim B. Heino" <Kim.Heino@bluegiga.com> -Erik
2001-12-19Update my email address. I am no longer andersen@lineo.comEric Andersen
2001-12-19merged the two startup files so that uClinux people always get the correctDavid McCullough
arg processing whether they are using PIC or not, and vice-versa for the MMU folks.
2001-11-19Add an initial clone from glibc. Needs fixing.Eric Andersen
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
2001-10-17Bring these into line with glibc 2.2.4Eric Andersen
2001-10-17This header file was broken, breaking signal handling on ARM.Eric Andersen
This update fixes it... -Erik
2001-10-12A small patch from Erwin Authried <eauth@softsys.co.at>Eric Andersen
*) changed ARM crt0.S / crt0pic.S selection -- depends on DOPIC now. *) Minor tweek to syscall definitions
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 :-(
2001-09-27Sigh. Erik mucks it up again...Eric Andersen
