427e6afdb8 Fixed OPDEF opcode generation (improper use of bitwise operators) 2017-04-04 11:26:49 -07:00
Jeff
d28d1ee940 Added a few PDP-10 byte pointer fixes, along with the ability to pass MACRO-10 text directly into the MACRO-10 assembler (use the Debugger's "as" command) 2017-04-04 10:42:41 -07:00
Jeff
38f709bb7a Corrected a few expression parser changes that had adversely affected other debuggers (eg, PCx86) 2017-04-03 16:27:52 -07:00
Jeff
09dc4dcb9a Lots of MACRO-10 improvements, DAKAM now assembles (but does not pass) 2017-04-03 16:10:08 -07:00
Jeff
3fb3f44384 Made a tiny 72-bit division optimization 2017-04-02 11:43:54 -07:00
Jeff
01550cc95e Well, that was brutal, but ALL the PDP-10 DAKAL multiplication and division tests FINALLY pass 2017-04-02 10:35:59 -07:00
Jeff
493ae6c310 I *think* all the PDP-10 DAKAL multiplication tests pass now. Division tests, alas, are a different story. 2017-04-01 23:06:41 -07:00
Jeff
470bd1d69e Fixed unary operators applied to bracketed expressions 2017-04-01 21:11:01 -07:00
Jeff
1a8c1306d4 Fixed 36-bit multiplication results in cases of overflow 2017-04-01 15:14:27 -07:00
Jeff
75b9a9c2ba Fixed the Debugger's arithmetic truncation function (truncate()) 2017-04-01 14:36:39 -07:00
Jeff
1711393755 Fixed 36-bit multiplication in the expression parser so that, within the PDP-10 environment, it produces the same 36-bit results that a PDP-10 would produce (important for MACRO-10 compatibility) 2017-04-01 00:43:44 -07:00
Jeff
26de8bbb1a Added another PDP-10 KA10 diagnostic (DAKAL) 2017-03-31 19:52:11 -07:00
Jeff
1786b3bf31 Fixed some regressions in MACRO-10 support (all the KA10 diagnostics archived so far assemble and pass again) 2017-03-31 18:43:13 -07:00
Jeff
afd621dc79 Updated the PDP-10 DAKAK diagnostic page, and verified the ability to assemble (but not run) all the original DAKAK source files, after making further improvements to the built-in MACRO-10 Mini-Assembler 2017-03-31 16:32:37 -07:00
Jeff
e7988597c5 Changed the remainder operator from '%' to '^/', mainly because '%' must be allowed in MACRO-10 symbols instead, but also because '%' led one to believe it was a "mod" operator (it wasn't); added IFDEF support to the MACRO-10 Mini-Assembler; updated the Debugger's assemble command to recognize filenames with "KLM" extensions, too. 2017-03-31 09:37:38 -07:00
Jeff
71e2ecb5cb PDP-10 "DAKAK" multiplication diagnostic passes 2017-03-31 08:14:56 -07:00
Jeff
307517fd76 PDP-10 multiply diagnostic testing finally underway; fixed one bug related to the KA10 (not that anyone really cares anymore) 2017-03-30 23:46:01 -07:00
Jeff
90ae3f1db8 Fixed the signed 8-bit calculation of all PDP-10 shift/rotate counts; diagnostic DAKAJ now passes 2017-03-30 17:31:13 -07:00
Jeff
881da5b19c Added another PDP-10 diagnostic (DAKAJ), which in turn required some more MACRO-10 support (eg, macro parameters with backslashes) 2017-03-30 16:04:00 -07:00
Jeff
3f06667597 Fixed/simplified opASH() a bit; it wasn't preserving the sign bit in all cases, and converting the input from unsigned to signed and back again was more confusing than helpful 2017-03-30 14:49:49 -07:00
Jeff
c6de12287c Documented a (mildly) interesting MACRO-10 bug 2017-03-30 12:43:24 -07:00
Jeff
1d1ac0cb7b The shared expression parser now adapts to the (critically) different precedence of MACRO-10 operators 2017-03-30 11:53:21 -07:00
Jeff
ab41fdef3c More robust handling of PDP-10 memory errors (so that when a file is assembled and loaded into non-existent memory, an error is generated); bumped the PDP-10 test machine to 32K words 2017-03-30 09:57:53 -07:00
Jeff
ec642a8c5b Made the Debugger's assemble command more flexible (the target address is optional now; the Debugger will use whatever load and/or start addresses the file(s) specified instead) 2017-03-30 09:04:56 -07:00
Jeff
15417ca686 DAKAG PDP-10 diagnostic passes now (fixed the relative addressing location used within literal scopes) 2017-03-29 13:59:50 -07:00
Jeff
c045e78395 Added the DAKAG PDP-10 diagnostics, implemented PUSHJ and POPJ instructions, and improved the debugging of XCT sequences 2017-03-29 13:26:23 -07:00
Jeff
d0ff759684 Added MACRO-10 support for OPDEFs, which are macro-like statements used to generate words which can also be combined with addressing modifiers 2017-03-29 10:12:45 -07:00
Jeff
642e43937e Assemble commands can now be batched up; even if they refer to external files that must be loaded asynchronously, command processing will be suspended until assembly is complete 2017-03-29 08:14:07 -07:00
Jeff
5a8a76249a Reordered flag output in the debugger to match bit order 2017-03-28 16:31:02 -07:00
Jeff
f8bf346eab Renamed flags to be more consistent with DEC's names, and updated JSR and JSP to clear the BIS flag 2017-03-28 16:27:18 -07:00
Jeff
d5c48df9bc Added support for MACRO-10 literal collapsing; it's not super-aggressive, but it's more than adequate for what DEC's diagnostics require 2017-03-28 15:22:17 -07:00
Jeff
776e225920 Fixed parsing of expressions with spaces 2017-03-28 09:27:32 -07:00
Jeff
ae30a5e93c PDPjs passes the first four PDP-10 Basic Instruction Diagnostics (finally) 2017-03-27 19:00:10 -07:00
Jeff
85fd72e6d4 Fixed a couple of PDP-10 opcode emulation bugs (AOBJN, AOBJP, and CMP), and rounded out the set of DEC's basic instruction diagnostics 2017-03-27 11:45:37 -07:00
Jeff
1b0e01c66a Improved MACRO-10 addWord() parsing 2017-03-24 13:44:34 -07:00
Jeff
471a93353e Fixed MACRO-10 literal processing (literals need to be evaluated as early as possible, but not allocated until the end is reached) 2017-03-24 00:09:30 -07:00
Jeff
40c588a069 Starting work on v1.34.3 2017-03-21 14:32:50 -07:00
Jeff
1c69d1f9c5 Added the unary + operator, and cleaned up the display of values from the expression parser 2017-03-21 12:48:44 -07:00
Jeff
a6021441c3 Fixed the signed truncation of 36-bit values (so that "-34,359,738,368. - 1" correctly produces "34359738367. aka 0o377777777777"), added the proper the right-to-left parsing of unary operators (all two of them: negate and complement), changed the PDP-10 disassembler to honor the selected base when displaying opcodes, and updated all the number-to-string conversions to select an appropriate number of digits when rendering values without a specified number of digits. 2017-03-20 13:34:25 -07:00
Jeff
822d400f27 Fixed PDP-10 debugger dump output when using the "db" command 2017-03-19 22:54:57 -07:00
