- Log message:
- 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.
