Rev	Log message	Author	Age	Path
93	A BINUTILS BACKEND IS NOW AVAILABLE!!!!	dgisselq	3003d 11h	/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	3003d 12h	/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	3034d 13h	/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	3040d 18h	/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	3101d 18h	/zipcpu/trunk/sw/
59	Adjusted these library routines to use the new stack frame and calling conventions.	dgisselq	3101d 18h	/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	3111d 20h	/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	3111d 20h	/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	3111d 20h	/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	3111d 20h	/zipcpu/trunk/sw/
