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. -Erik

Here are a number of minor changes to FR-V-specific bits of the uClibc port: - I've adjusted the definition of _dl_mmap to cope with the fact that there will be a definition for an mmap2-only system. - We don't have COPY relocs, so optimize the copy reloc-related code away. - Change the page size to 16KiB, to match the ABI spec, and not a stale value I'd copied from a linker config file. Oops. - Fix error handling in clone and vfork; parts of the changes by David Howells <dhowells@redhat.com> - Rearrange includes in crtreloc.c. - Change the API of __syscall_error, to reduce code size. - Improve __syscall_return in terms of code size, so as to enable tail-calling of __syscall_error, at least within libc. Ideally, __syscall_error should be hidden within libc.so, but this didn't work because of libdl. I haven't looked into why, and figured I'd leave it visible for now. - Rename enumerators and macros in sys/ucontext.h to reduce namespace pollution.

I added this function after I posted the last version of the FR-V patch. Add syscall.c.

This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem.
