97 Added longjump instructions. dgisselq 2983d 19h /zipcpu/trunk/sw
96 Added the longjump functionality, so that the assembler will properly assemble
instructions to arbitrary 32-bit addresses.		 dgisselq 2983d 19h /zipcpu/trunk/sw
95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.		 dgisselq 2986d 01h /zipcpu/trunk/sw
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 3010d 22h /zipcpu/trunk/sw
93 A BINUTILS BACKEND IS NOW AVAILABLE!!!! dgisselq 3018d 20h /zipcpu/trunk/sw
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 3018d 20h /zipcpu/trunk/sw
70 Updated the assembler support files, zopcodes in particular, to handle
the disassembly of the new very long instruction word codes.		 dgisselq 3049d 22h /zipcpu/trunk/sw
69 This implements the "new Instruction Set" architecture for the Zip CPU. It's
a massive change set, that touches just about everything but probably not
enough of everything. Please see the spec.pdf for a description of this
new architecture.		 dgisselq 3056d 02h /zipcpu/trunk/sw
60 Fixed assembler processing of jump instructions, so that the new fast
return instruction can be used. The test file was modified to test
pipelined value passing within the CPU. That's where the value gets
(re)used before being stored back in the register file. As of this release,
all tests work.		 dgisselq 3117d 03h /zipcpu/trunk/sw
59 Adjusted these library routines to use the new stack frame and calling
conventions.		 dgisselq 3117d 03h /zipcpu/trunk/sw
