100 Some changes to support early branching: branches are now ADD #x,PC instructions
instead of MOV #x(PC),PC--providing greater range to the CPU. When that range
is insufficient, ZPARSER now recognizes long jump instructions coded as
LOD (PC),PC followed by the jump address. (This change was made necessary by
the need to build an assembler/linker that could create instructions that would
jump to any address in the 32-bit address space. In short, a part of the
ongoing GCC upgrade and rework.)

99 Added big-endian versus little-endian functionality. You can now specify which
your input file is as a command line parameter, and zdump will properly
disassemble the file.

98 Added justed longjump instructions from the previous (not used, broken)
functionality to the new LOD (PC),PC functionality.

97 Added longjump instructions. dgisselq 3607d 07h /zipcpu/trunk/
96 Added the longjump functionality, so that the assembler will properly assemble
instructions to arbitrary 32-bit addresses.

95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.

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/.

93 A BINUTILS BACKEND IS NOW AVAILABLE!!!! dgisselq 3642d 08h /zipcpu/trunk/
92 Adjustments made to match the simplified early branching. dgisselq 3642d 08h /zipcpu/trunk/
91 Minor updates. dgisselq 3642d 08h /zipcpu/trunk/
