122 This represents a major rewrite of the machine definition file, gcc/config/zip/
zip.md. In particular, the architecture has been changed from a "cc0"
architecture to one with a specific CC_REG and CCmode. Instructions in the
machine definition file must now explicitly set this register with their
results. The result is better condition code handling, better usage of the
conditional execution modes of certain instructions, and even some decent
optimizations.

117 Bug fixes: This adds the zip_ucc() instruction as a builtin, fixes the zip_cc()
builtin (both are now unspec_volatile) together with fixing the *_context(int*)
builtins so that they use five registers, never four. Further, this fixes the
negative stack space offset bug. Many of the GCC files now have Zip debugging
hooks within them as well, to simplify further debugging of the compiler.

112 Removed some debugging code from the compiler. dgisselq 2925d 07h /zipcpu/trunk/sw/gcc-zippatch.patch
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.

103 A barely functional, but somewhat working, version of GCC to check in.
If the Lord is willing, it should be accompanied by a newlib port soon.
That port should move the GCC status from barely functional but somewhat
working to functional and working, although not (yet) complete.
dgisselq 2942d 12h /zipcpu/trunk/sw/gcc-zippatch.patch
102 Updated bugfix version of the binutils patch, and a first patch of GCC.
The GCC patch is undergoing ongoing and active development. It is also known to
continue to contain active bugs. (It's not done yet.)
