1681 5935d 09h fabio /shark/branches/xen/ Redesign the build system.

Switch to a non-recursive easy to configure build system, with a topdir
makefile that collects information on the targets to build from the subdirs
and generates the needed targets and commands. The ports and demos are
still not connected to the build. The new build system is documented
in the main makefile.
 
1621 5965d 10h fabio /shark/branches/xen/ Move all the low level libc related headers from the OSLib to libc/.

Move the headers used to define the libc interface exported by Shark from
the OSLib to libc/arch/$(ARCH) (remember, by now ARCH can be only x86,) and
change their users to reflect the movement. There are still a couple of
problems to solve, that are how to deal with the libc code used inside the
kernel, and how to handle things that are on the boundary, e.g., some type
definitions and so on. Btw this had to be started from somewhere.
 
1619 5965d 14h fabio /shark/branches/xen/ Move the OSLib libc/libm code into libc/arch.

Isolate the libc/libm code inside the OSLib and move it to libc/ with
the long term goal of isolating and cleaning up the interfaces between
the system components. The ARCH configuration variable will choose
the architecture Shark is being compiled for.

Now the architecture specific part of the libc is in libc/arch/$(ARCH),
but the include/makefile support is far from being generic enough.
 
1618 5966d 04h fabio /shark/branches/xen/ Started a new xen/ branch.

The plan is to support xen (without HVM) as an execution platform, and,
in the process, to decouple the generic kernel from the OSLib, trying to
make it easier to port Shark to new architectures.
 
1073 6303d 15h tullio /shark/trunk/ Updated makefiles to consider the new shark.cfg COMPILER option.  
1063 6317d 18h tullio /shark/trunk/ Added missing GPL license disclaimer.  
1061 6392d 14h tullio /shark/trunk/ Added clearer comments to make modifications to config files easier in order to support older gcc versions.  
1056 6428d 23h tullio /shark/trunk/ Added gcc 4x support. Actually, tested with version 4.1.2.
Into code, updated some constructs that were not compatible with gcc 4x.
Into config files, added compiler flags to suppress some warnings (turned as default since gcc 4x) and turned off optimizations for inline code, which generated unwanted calls to builtin memcpy.
