This patch makes -fpic work for PCC and optimzes the relcation by moving the cache flushing stuff to JMP relocs only. Actually PPCs ldso can only handle small GOT tables(<=8192 entries)anyhow, so it makes little sense to compile PPC with -fPIC. libuClibc shrunk from 340724 to 330780 bytes with -fpic.
2004-07-16Hide the arm libfloat support for now. No longer needed for gcc 3.4.1 andManuel Novoa III
won't be needed for 3.3.4 either when I get some time to clean up that toolchain which also suffers from the g++ include dir search order bug.

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.

2003-11-23Ok.. this fixes the buildroot soft-float arm build.Manuel Novoa III
Also try to make sure the build breaks if we want soft float but don't know how to request it.

2003-10-31Some more soft float fixes... for arm in particular (libfloat).Manuel Novoa III
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.

2003-08-13Patch from Paul Mundt adding uClibc sh64 support:Eric Andersen
Here's a patch that implements the beginnings of a rudimentary sh64 port. So far, this only works static, as I haven't done any of the ldso work yet. I've also not touched the libpthread stuff yet either, so that's also disabled for now. This port was based off of some work that Sean McGoogan at SuperH did for his initial port, but the this patch doesn't carry over too much from there (basically the libc/sysdeps/linux/sh64/Makefile (or rather, parts of it), the setjmp/longjmp stuff (which I had to rewrite portions of it to work with the new toolchains), etc.). However, for static, everything appears to work correcly, at least in a hello world type application.
