cisc-0.2/programs, branch new-instruction-handler An emulator for the Sux instruction set. https://git.b0nk.xyz/cisc-0.2.git/atom?h=new-instruction-handler 2021-05-09T16:32:11Z Subtract another 16 from the size in clr_arr. 2021-05-09T16:32:11Z mrb0nk500 b0nk@b0nk.xyz 2021-05-09T16:32:11Z urn:sha1:640037b972d022fc6877b4d2e1f51f329cbec9ea This fixes a bug where it would zero out the info of the next malloc'd block. Replace call to memcpy, with call to memcpy_dir. 2021-05-09T16:23:39Z mrb0nk500 b0nk@b0nk.xyz 2021-05-09T16:23:39Z urn:sha1:f8c2e25b4ab337789a2e468a8f0aadb0c7fda42f This fixes a bug where when shifting the line left, it would overwrite everything after the cursor with the character at the cursor's position. The reason this was happening is because memcpy copies from start to end, and because the destination is more than one byte ahead of the source, it overwrites the next length source bytes, which will repeat until it's copied n bytes. Add a end to start version of memcpy, and a selectable 2021-05-09T16:19:34Z mrb0nk500 b0nk@b0nk.xyz 2021-05-09T16:19:34Z urn:sha1:98886be8aa8508feabbcd8f232ba85ef46a7a139 direction version of memcpy. This can help with some subroutines/functions like shftln, which need to copy data in a certain direction depending on the condition. Fixed a bug in print_char caused by not zero extending 2021-05-08T19:04:31Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T19:04:31Z urn:sha1:eb679e0750798c0fcba06d10d8b003532d931644 `b`. Fixed a bug in print_str to do with clobbered 2021-05-08T19:01:36Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T19:01:36Z urn:sha1:607ca37ab87095ac5d79f9a1646a253df633c2e3 registers. This was due to print_char clobbering `d` when calling get_index. Replace get_ctrlidx with get_index in print_char. 2021-05-08T18:58:44Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T18:58:44Z urn:sha1:01c8e7399cc940d2d5d0540593e16724948bd6e3 This helps reduce code duplication, and makes it easier to both read, and add new handlers. Add a new subroutine called get_index. 2021-05-08T18:53:21Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T18:53:21Z urn:sha1:d284bfb53d27831c1bfa1b39a265eab748217cea This subroutine gets the index of a given character from a string. This will help in replacing some routines like get_ctrlidx, isdelm, and isdelm2. Get the pointer from the control code handler table 2021-05-08T17:16:32Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T17:16:32Z urn:sha1:875dff40ad71847d59c272491e516e4b1f01058c using SIB, rather than with lsl. This doesn't increase, or decrease the code size, but does make it both more compact, and easier to read. Rewrite `clr_arr` to use the ortho extension. 2021-05-08T16:48:50Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T16:48:50Z urn:sha1:5db9af7b0d1d027b9325b45917ab46beaa52d5a0 This makes the code much smaller than the previous version. Replace all instances of $/0x1B with the escape 2021-05-08T16:46:39Z mrb0nk500 b0nk@b0nk.xyz 2021-05-08T16:46:39Z urn:sha1:6cb51003b5afeb061955925e4d704743925893da sequence for the escape character.
