97 Added longjump instructions. dgisselq 2981d 19h /zipcpu/
96 Added the longjump functionality, so that the assembler will properly assemble
instructions to arbitrary 32-bit addresses.		 dgisselq 2981d 19h /zipcpu/
95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.		 dgisselq 2984d 01h /zipcpu/
94 These changes make it possible to build binutils-2.25/ here in this
directory. "make binutils" should be all that is necessary to build the
entire binutils package for the Zip CPU.

The default configure script, run from gas-script.sh below, will build and
install these utilities in an install/ subdirectory made below sw/.		 dgisselq 3008d 22h /zipcpu/
93 A BINUTILS BACKEND IS NOW AVAILABLE!!!! dgisselq 3016d 20h /zipcpu/
92 Adjustments made to match the simplified early branching. dgisselq 3016d 20h /zipcpu/
91 Minor updates. dgisselq 3016d 20h /zipcpu/
90 Removed MOV x(PC),PC from the list of possible early branching instructions.
ADD X,PC and LDI X,PC are now the only recognized early branching instructions.
This was done to spare logic, although I don't think I spared more than a
LUT or two.		 dgisselq 3016d 20h /zipcpu/
89 Minor changes, to include making default branching an ADD.[condition] X,PC
instruction, rather than allowing both MOV X(PC),PC and ADD X,PC instructions.

Further zopcodes.cpp contains several bug fixes.		 dgisselq 3016d 20h /zipcpu/
88 Eliminated some warnings. The div fixes were to simplify the logic, even though
the result is less readable ...		 dgisselq 3040d 19h /zipcpu/
