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.

118 Fixes two bugs: 1) in the early branching code within the instruction decoder.
This prevented the early branching from working when built with Xilinx's tools,
while the code worked with Verilator. 2) The CPU was not working with the
traditional cache and early branching disabled. These two bugs masked each
other. The replacement code is simpler.
dgisselq 2992d 22h /
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 2993d 06h /
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 2993d 06h /
115 A bug fix, applies to when there are more than 9 interrupt lines into the CPU. dgisselq 2993d 06h /
114 Fixes a bug that killed make binutils before the build-gas directory
was created.
dgisselq 2998d 07h /
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 2998d 10h /
112 Removed some debugging code from the compiler. dgisselq 3001d 06h /
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.
dgisselq 3001d 06h /
110 The makefile no longer requires (or supports) building the obsolete machine
code test file optest.
dgisselq 3001d 06h /
