95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.
dgisselq 3062d 07h /zipcpu/trunk/sw/zasm/
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 3095d 02h /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 3126d 04h /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 3132d 08h /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 3193d 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 3203d 11h /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 3203d 11h /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 3203d 11h /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 3203d 11h /zipcpu/trunk/sw/zasm/
51 Added the capability to look at binary files and 'see' characters as they
are encoded in memory.
