102 Updated bugfix version of the binutils patch, and a first patch of GCC.
The GCC patch is undergoing ongoing and active development. It is also known to
continue to contain active bugs. (It's not done yet.)		 dgisselq 3015d 05h /zipcpu
101 Adjusted the "BREAK" instruction so that it will now disassemble properly
with an operand. This was necessary to create a (trap_if ...) instruction
for the GCC compiler.		 dgisselq 3017d 08h /zipcpu
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.)		 dgisselq 3017d 08h /zipcpu
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.		 dgisselq 3017d 08h /zipcpu
98 Added justed longjump instructions from the previous (not used, broken)
functionality to the new LOD (PC),PC functionality.		 dgisselq 3017d 08h /zipcpu
97 Added longjump instructions. dgisselq 3017d 08h /zipcpu
96 Added the longjump functionality, so that the assembler will properly assemble
instructions to arbitrary 32-bit addresses.		 dgisselq 3017d 08h /zipcpu
95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.		 dgisselq 3019d 14h /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 3044d 11h /zipcpu
93 A BINUTILS BACKEND IS NOW AVAILABLE!!!! dgisselq 3052d 09h /zipcpu
