95 Fixed a bug whereby a mistaken code for CLR was masking a valid LDI of a large
integer value.
dgisselq 2403d 19h /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 2436d 14h /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 2467d 16h /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 2473d 20h /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 2534d 21h /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 2544d 23h /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 2544d 23h /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 2544d 23h /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 2544d 23h /zipcpu/trunk/sw/zasm/
51 Added the capability to look at binary files and 'see' characters as they
are encoded in memory.
