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	3049d 10h	/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	3110d 10h	/zipcpu/trunk/sw/
59	Adjusted these library routines to use the new stack frame and calling conventions.	dgisselq	3110d 10h	/zipcpu/trunk/sw/
55	A test was added to double check whether carry following right shifts worked. This was a necessary part of getting two cycle linear feedback shift register operations working for a memory test on a XuLA2 board. With this, I can now verify that such feedback registers work for pseudorandom number purposes.	dgisselq	3120d 13h	/zipcpu/trunk/sw/
54	This builds on the support for backslash character escapes in both single and multicharacter expressions. Backslash character escapes are now possible with quotations and backslashes, and the same code to interpret the escapes is applied to both single and multicharacter sequences.	dgisselq	3120d 13h	/zipcpu/trunk/sw/
53	Updated the #include/#define directives to work properly for nested includes. (They were supposed to work properly for nested includes before ... and didn't) This fixes those bugs.	dgisselq	3120d 13h	/zipcpu/trunk/sw/
52	Added the capability to "see" character's encoded within a binary file, by printing the character value(s) of each opcode (if they are printable) on each line.	dgisselq	3120d 13h	/zipcpu/trunk/sw/
51	Added the capability to look at binary files and 'see' characters as they are encoded in memory.	dgisselq	3120d 13h	/zipcpu/trunk/sw/
46	A series of updates associated with getting Dhrystone to work. Includes updates to getting multiple files to link/work together within the assembler, as well as getting quoted quotations to work in the lexer, and better include file support in the preprocessor.	dgisselq	3130d 04h	/zipcpu/trunk/sw/
45	Library routines for 32-bit multiply and divide, both signed and unsigned.	dgisselq	3130d 04h	/zipcpu/trunk/sw/
