124 Lots of changes, lots of bugfixes--both to the compiler as well as to the
assembler. (Ex: the assembler will now properly execute a LDI _sym+5,R0).
Many compiler optimizations have been turned off, however. They will probably
be turned back on in the near future--once I get this version proven without
them.

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.
dgisselq 2368d 14h /zipcpu/trunk/sw/gcc-zippatch.patch
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 2380d 20h /zipcpu/trunk/sw/gcc-zippatch.patch
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.
dgisselq 2380d 21h /zipcpu/trunk/sw/gcc-zippatch.patch
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 2398d 02h /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.)
