uClibc uses wrong word order in vfp floating point arithmetic.
I found this using my modification to N. Pitre's soft-float gcc patch, but this modifications were
made just to allow gcc to compile code for armv4l, while nothing about fp arithmetic was changed.

that the old stat.h abi was for little endian only ... people should use this patch to fix their armeb kernels: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=863/1

be able to run apps built with 0.9.27. This also renames
__uClibc_start_main to __uClibc_main.
This compat option should be removed some time after 0.9.28 is released.
Let me know if you don't like this change.

The Arm crt0.S contains non-PIC code for locating _init and _fini sections.
This caused problems on my uclinux system when static constructors were
enabled.
The attached patch implements a PIC version of this code.

i sent this earlier but perhaps people missed it the first time around :)

basically if you try to #include <sys/ucontext.h> on arm it'll fail because
ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has
this fix in uClibc
find attached a trivial patch to fix this

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.

Some utilities, such as valgrind, have a legitimate reason to know the address
of the current brk. Since we know such utils will peek under our skirt, we
might as well give them what they expect and not use a gratuitously different
symbol name.

have it. It is used by the boehm gc, amoung other things.

Because variables are linked to fixed registers, there is a problem in :
(*__errno_location())=(-_r0);
As __errno_location() uses r0 to return the address of the errno location,
the negated address will be assigned instead of the error code.
Attached patch will resolve this.

'__kernel_old_dev_t'. And of course there is no good way to know
which is in use except checking linux/version.h. Grumble.
This is rather lame, but for now, define __kernel_old_dev_t to be
the same as __kernel_dev_t. This will want to be revisited soon.

Hi Eric,
The attached diff file includes BUS_ISA fix for kernel since 2.4.23/
Kind regards,

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.
