Hello Erik! I have made some cosmetical changes to the files, removed the added SCRT=-fPIC option from building the crt0.S file (but it is a requirement to build them with -fPIC), and changed some comments. I have left the ldso.c patch with PIE_SUPPORT ifdefs, but consider applying it w/o them (see some earlier comment from PaX Team on this issue, as it is considered a bug). To have it work correctly, you'll also need removing COMPLETELY_PIC. One thing is missing: PIE_SUPPORT should be usable only for i386 (for now). Also added the support for propolice protection (that works for me and catches memcpy/strcpy attacks (but needs a special gcc version). Thanks, Peter
2003-12-03Lethal noticed that the generated file gmon-start.S was notEric Andersen
being cleaned up.
2003-11-22Remove SAFECFLAGS. It was a workaround for failures in old awk scriptEric Andersen
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.
2003-11-08Darn. Fix compilation for soft-float, which I inadvertantlyEric Andersen
broke a couple of days ago. :-(

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.

rm.patch: * Define $(RM) as rm -f in Rules.mak and test/Rules.mak (this is the same definition as gmake uses by default). * Change all occurrences of rm and rm -f into $(RM).
2003-10-08Patch from Atsushi Nemoto (with some additions):Eric Andersen
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.
2003-09-21Fix "subst -g,," problem for SAFECFLAGS.Manuel Novoa III
2003-09-07Some updates from glibc. mjn3 reports this fixes profilingEric Andersen
on i386, at least, so seems like a good thing.
2003-09-07i386/mcount.S expects to call __mcount_internal with the 2 args passedManuel Novoa III
in registers. NOTE: i386/mcount.S really needs to be rewritten. It currently won't work for non-PIC builds.

2003-05-30Clone still had a few little PIC problems....Eric Andersen
2003-05-30In a number of places we erroneously used tests such as '#ifdef PIC' when weEric Andersen
should instead have been testing for '#ifdef __PIC__'. This resulted in NON-PIC code getting mixed into the shared library. Oops!!! -Erik

2003-02-03Oops. I'd left an extra invocation of sigaction in there...Eric Andersen
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 a tiny bitEric Andersen
2003-01-23simpler method for getting a 'main' reference. Make _init and _finiEric Andersen
be weak so people won't need to fix their compilers
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
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
2002-11-29I 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
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.

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
2002-08-24Tweak things so that struct stat and struct stat64 (seem to) work onManuel Novoa III

2002-07-15Clean up CLK_TCK situation. clock() and sysconf() now use anManuel Novoa III
arch-specific constant value defined in bits/uClibc_clk_tck.h. Default is 100 (common/bits) but alpha uses 1024 following glibc. Override per arch as necessary.
2002-04-14Fix dummy main reference so it works...Eric Andersen
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
