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
d13e7a5faf The expression parser now allows spaces inside expressions (a relaxation for certain MACRO-10 typos; eg, "- 1" where "-1" was expected) 2017-03-28 12:01:06 -07:00

6ad35d2d17 Added the ^L MACRO-10 unary zero-bit-counting operator, and updated the last blog post with expression parser differences (eg, interpretation of numbers with a decimal point) 2017-03-21 17:40:37 -07:00

127ddb88b4 Added the unary + operator, and cleaned up the display of values from the expression parser 2017-03-21 12:47:43 -07:00

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

65eb821710 Well, apparently the PDP-10 MUL instruction really DOES store the high-order word first, and it only stores the low-order word if the destination is an accumulator (weird) 2017-03-07 14:09:24 -08:00
Jeff

04ae721eb6 Updated the extended logical operations (LSHC and ROTC) to treat the result as a 71-bit result, and ASHC to treat it as a 70-bit result 2017-03-06 16:42:29 -08:00
Jeff
3d4795bbe4 Updated the Int36 class with support for both signed 71-bit values (my original double-length format) and 70-bit values consisting of two signed 35-bit values (DEC's double-length format) 2017-03-06 15:48:31 -08:00

c0de732f76 Changed toStrBase() to accept a number of bits rather than a number of bytes, because bytes aren't always 8 bits (see PDP-10) 2017-02-24 10:58:56 -08:00

b1d16c979a Removed obsolete version of Int36 (using signed integers internally); sticking with unsigned integers internally not only simplifies some of the existing logic, but will make it easier to add logical operations later (eg, AND, OR, XOR, etc) 2017-02-18 09:36:47 -08:00
