Rev	Log message	Author	Age	Path
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	3011d 01h	/zipcpu/trunk/sw/zasm
70	Updated the assembler support files, zopcodes in particular, to handle the disassembly of the new very long instruction word codes.	dgisselq	3042d 03h	/zipcpu/trunk/sw/zasm
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	3048d 07h	/zipcpu/trunk/sw/zasm
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	3109d 08h	/zipcpu/trunk/sw/zasm
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	3119d 10h	/zipcpu/trunk/sw/zasm
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	3119d 10h	/zipcpu/trunk/sw/zasm
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	3119d 10h	/zipcpu/trunk/sw/zasm
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	3119d 10h	/zipcpu/trunk/sw/zasm
51	Added the capability to look at binary files and 'see' characters as they are encoded in memory.	dgisselq	3119d 10h	/zipcpu/trunk/sw/zasm
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	3129d 02h	/zipcpu/trunk/sw/zasm
