Kill old crt0/__uClibc_main.
This breaks ABI. All apps and toolchain needs to be recompiled.
All archs except x86 are now broken and need to be fixed as x86.
PPC will be fixed shortly by me, the rest is left to the arch maintainers.

all cases, but the archs I've looked at do build the needed routines as
PIC so we should be ok.
|
|
|
|
Remove the ADD_LIBGCC_FUNCTIONS option and do things the right way.
Either we have a shared libgcc available, or the libgcc routines
aren't PIC and don't belong in the shared libc anyway.

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).
|
|
install.patch:
* Define $(INSTALL) as install in Rules.mak.
* Change all occurrences of install into $(INSTALL).
* Change all occurrences of mkdir -p into $(INSTALL) -d.
install -d is already used in a number of places so
this should not be an additional compatibility problem.

The attached patch allows $(CC) to contain spaces
(something which we use).

option, to avoid the possibility of adding non PIC code into the shared PIC
uClibc library, thereby making the .text segment unshareable.

configurable, so people who do not need or want ctor/dtor support
can disable it and make their binaries a little bit smaller.

this is the last patch, we need to make the support of multitarget libgcc
complete.
---------------------------------
In ldso/ldso/Makefile
I added the CPU_LDFLAGS-y to the LDFLAGS
---------------------------------
In libc/Makefile
I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y
---------------------------------
In extra/scripts/get-needed-object.sh
we now use the LIBGCC from Rules.mak and call LD with LDFLAGS
(==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved
external __GLOBAL_OFFSET_TABLE__ on SuperH targets.
---------------------------------

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.

exists read it and include it when linking.
* Add LIBGCC when linking libc.

can live with much better the what glibc does.

get-needed-libgcc-objects.sh
to we define NM and AR properly.

when cross compiling with shared lib support, there were spots
where the native 'ld' was mistakenly being called.
|
|
|
|
|
|
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.
