95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.
dgisselq 2358d 05h /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 2391d 00h /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 2422d 02h /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 2428d 06h /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 2489d 07h /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 2499d 09h /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 2499d 09h /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 2499d 09h /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 2499d 09h /zipcpu/trunk/sw/zasm
51 Added the capability to look at binary files and 'see' characters as they
are encoded in memory.
