objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

Below is a patch to make the pread and pwrite calls work on the SH
architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a
fairly recent kernel is required as the problem is partially fixed in
the kernel itself. For more information (in relation to glibc, but the
problem is the same) see the thread at
http://sourceforge.net/mailarchive/message.php?msg_id=2375908
Someone should really test this on the SH2/3...

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.

Untested, but syscall() is needed by busybox for pivot_root at least.

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().

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...

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)

method for building crti.o and crtn.o
|
|
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,

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.
