Jeff Parsons	f0f3d8fa42	Added v1.35.0 files	2017-06-15 15:12:30 -07:00
Jeff Parsons	3e1aa196bd	Added an empty 10Mb disk image formatted by PC-DOS 2.0 (currently used by one machine: 5160/cga/640kb); also fixed some issues uncovered in the process of creating the disk image (eg, a bug in the HDC's save logic when no image has been loaded), and made some fixes and optimizations in DiskDump	2017-06-01 15:32:17 -07:00
Jeff	ea95de4939	Fixed (or rather, band-aided) a MACRO-10 regression assembling the nested macro test (/apps/pdp10/tests/macro10/TEST.MAC)	2017-04-05 20:42:44 -07:00
Jeff	5f72f1627f	Updated the first PDP-10 reliability test (DAKBA)	2017-04-05 16:33:16 -07:00
Jeff	6bd24c5347	Fixed how index operands are assembled into PDP-10 instructions, which was an unexpectedly convoluted process (they are NOT masked to 4 bits, shifted left 18 bits, and OR'ed into the opcode; instead, they are computed as a 36-bit value whose left and right 18-bit halves are swapped and then ADDED to the opcode, which means that an instruction encoded with indexing may not end up using indexing at all, depending on where all those bits fall)	2017-04-05 12:38:36 -07:00
Jeff	d4c12c8c7a	Fixed the PDP-10 BLT instruction	2017-04-05 11:32:16 -07:00

Jeff	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	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	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
