Add more missing objects: mostly math functions.
Also remove redundant entries in morello.objects
and add a make file to check correctness of this
list. Force tests to fail on C64-to-A64 transition.
Use Morello version of compiler-rt builtins instead
of non-Morello libgcc. Update readme: how to build
Morello version of libclang_rt.builtins-morello.a.

The new implementation will copy memory tags for every 16-byte
aligned address. Possible chunks of size < 16 that may precede
or follow the 16-byte chunks will be copied in non-capability
aware way. Buffers of total size less than 16-bytes will also
be copied in non-capability aware way.

Previous implementation used non-capability instructions to copy
capabilities which resulted in occasional loss of memory tags.

The new implementation is significantly slower than the old one
(e.g. when dst and src addresses are misaligned) and should be
improved in the future.

Fixes sizing on some internal structures of pthread when compiling for
Morello (cond vars, mutexes, etc). This should now allow the use of
condition variables and mutexes, and one of the libc-tests has been
enabled correspondingly. Temporarily, the largest size for arrays within
the unions is always used, due to difficulty changing the size
conditional on the definition of MORELLO - however, this can be fixed
once all objects are being compiled for Morello within Musl.

Also fixes a couple of bugs with the implementation of __clone on
Morello.

This patch addresses #2.

Remove unnecessary Morello ifdef.
Use correct cast in mmap to avoid compiler warning.

This is just to make sure that they can both copy capabilities.

This used to happen when printing some plaintext with an \n while
building in non-optimised mode.

Adds basic support for pthread_join, pthread_create and
pthread_attr_init functions.

This is porting the minimum to get malloc and free to work. malloc-related
functions like realloc are not yet ported. It must also be noted that
malloc return a wide capability, one whose bound allow tamptering with
the metadata and with some adjacent malloc region. Narrowing this bound
require some non negligeable work, because free needs to access the
metadata.

Clang and GCC differ substantially in how they handle cross-compiling.
The configure scripts now takes the differences into account and
sets correct target flags. It also takes other binutils into
consideration.

Libshim does most of the work to cross-compile itself except to pass a
target flag to clang. Work around this and pass the flag.

This patch also switches the preparation of argv, envp and auxv on the
stack to do_raw_args_marshalling, provided by libshim.

Fixes: #1 issue.

These directories were only writeable by the user who created them,
which caused conflicts when multiple people want to run the tests on the
same machine. Setting the permissions to 0777 fixes this.

Check if the capability of the returned char * matches that of the provided
argument. This should always be true as they should be the same pointer.

add a test for creat function.

Change return value data type to preserve provenence if
capability type is returned by kernel.

Add syscall test to check if syscall interface works
with capabilities as intended or not.

This doesn't include the W familly of scanf (vfwscanf, vswscanf, etc.)
The %m option have been disabled for now until we get malloc support.

This is a trivial port. The tests are not complete though as they would
require setlocale which isn't ported yet.

Update sorting of morello.objects to use the command-line sort function
for consistency, and add guidance to README.rst on this command to use.

Add support for open(), openat(), creat() and fcntl(). Testing is not
yet fully featured, pending porting of a function such as mktemp().

family objects.

It is a trivial port. The function is just a getter to a static const
structure and the permissions are already correct (read only). The test
checks those permissions and attempts read/write.
