size and performance penalty to profiling applications this way, as well as
Heisenberg effects, where the act of measuring changes what is measured.
There are better tools for doing profiling, such as OProfile, that do not
require gcc to instrument the application code.

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

being cleaned up.

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.

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).

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.

generate a crt0 and crt1 file. Most arches still need
to be updated to call __uClibc_start_main() rather than
__uClibc_main().

much better now, for example, on multi-threaded apps.

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...

NOTE!!! This is run by "make -C libc/sysdeps/linux/$(TARGET_ARCH) headers"
in the main Makefile, but I only changed libc/sysdeps/linux/i386/Makefile
as I had no way of testing it for the other archs. Various arch maintainers,
please check and update the corresponding Makefile... or report bugs ;-)...
appropriately. You'll also want to "cvs del" syscall.h and add it to
a .cvsignore in $(ARCH)/bits.
Also added a define to uClibc_config.h, __UCLIBC_USE_UNIFIED_SYSCALL__, and
moved i386 unified syscall stuff out of common and into i386/bits/syscalls.h.

tree is less messy now (which helps), all libraries are placed into
uClibc/lib when compiling, all libraries now use a consistant mechanism
for being built, all libraries use a consistant naming scheme where the
lib name includes the uClibc version number, which makes ldconfig
happy and willing to work with us.
