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 2939d 10h /zipcpu/trunk/sw/
121 Fixed the bug whereby BGE instructions dissassembled as BGT instructions and
vice versa. Loads and stores of absolute addresses now show those addresses
in ($<>). The assembler also accepts integer offsets to symbols, although
it isn't clear that it does the "right" thing with them yet.		 dgisselq 2939d 10h /zipcpu/trunk/sw/
120 Should've regression tested that last build. This one fixes what that last
fix broke: Registers with offsets (i.e. operand-B) now work (again).		 dgisselq 2943d 05h /zipcpu/trunk/sw/
119 Fixed some limits bugs. Now LDI.Z 1 produces LDIHI.Z 0, LDOLO.Z 1 as desired
instead of the erroneous BREV.Z 0. Likewise, loading 0x80000000 no longer
produces a clear instruction, but actually loads the value of interest.		 dgisselq 2943d 06h /zipcpu/trunk/sw/
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.		 dgisselq 2943d 16h /zipcpu/trunk/sw/
116 Updated binutils. This fixes problems with linking global variables, fixes
the map file report, adjusts the LJMP instruction disassembly to display the
resulting address, as well as in general fixing up link problems when
sizeof(byte) is 32-bits.		 dgisselq 2943d 16h /zipcpu/trunk/sw/
114 Fixes a bug that killed make binutils before the build-gas directory
was created.		 dgisselq 2948d 17h /zipcpu/trunk/sw/
113 Bug fix: the Makefile wasn't building gcc, and the binutils would not allocate
space for common variables or zero'd (bss) variables properly. Several binutils
bugs were fixed to get variables to be allocated properly. Those are
reflected in this updated patch.		 dgisselq 2948d 21h /zipcpu/trunk/sw/
112 Removed some debugging code from the compiler. dgisselq 2951d 16h /zipcpu/trunk/sw/
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.		 dgisselq 2951d 17h /zipcpu/trunk/sw/
