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 2937d 07h /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 2937d 17h /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 2937d 17h /zipcpu/trunk/sw/
114 Fixes a bug that killed make binutils before the build-gas directory
was created.		 dgisselq 2942d 18h /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 2942d 22h /zipcpu/trunk/sw/
112 Removed some debugging code from the compiler. dgisselq 2945d 17h /zipcpu/trunk/sw/
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.		 dgisselq 2945d 18h /zipcpu/trunk/sw/
110 The makefile no longer requires (or supports) building the obsolete machine
code test file optest.		 dgisselq 2945d 18h /zipcpu/trunk/sw/
109 This file is now marked as obsolete. dgisselq 2945d 18h /zipcpu/trunk/sw/
105 Fixed some nasty early branching bugs. Adjusted the Makefile to declare that
cpudefs.h was automatically generated from cpudefs.v, and made sure that
zipbones included the cpudefs.v so it could get the DEBUG_SCOPE define.
In addition, the test.S was updated to test long jumps, the early branching
bug we found, and all three early branching instructions: ADD #x,PC, LOC(PC),PC,
and LDI #x,PC.		 dgisselq 2961d 18h /zipcpu/trunk/sw/
