2026-04-13fix some disagreements with the heap words implemented in ForthIrene Knapp
there's still pending disagreements with words implemented in assembly, which will be dealt with in another CL "forthcoming" :D Force-Push: yes Change-Id: I5420f79365bb1de4ff8e30d79212788251f871cf
2026-04-13add 2drop to describe-data.sedIrene Knapp
oops. missed this one, since it's never actually called so it showed up differently in the diff. Force-Push: yes Change-Id: Ia07b268ab736d06aa7d374654dd97baf14f84e1c
2026-04-13add another sed script, to remove absolute addressesIrene Knapp
this is useful for a different type of comparison Force-Push: yes Change-Id: I225af22586924a716c0d0802cda5194fd19d7d12
2026-04-13add some sed scripts to make the output easier to examineIrene Knapp
these separate out the data and heap segments; the one for the data segment also replaces all the flatassembler names with Forth names. the output of these scripts looks very clean when passed through diff, showing only important differences Force-Push: yes Change-Id: I868ca9817fa41d2c503a8480ae6ceb44c9e10df7
2026-04-13tweak how the spaces around "describe" are printedIrene Knapp
there had been trailing spaces in the output; now there aren't. happily, since this was just rearranging existing code snippets, there was no need to recalculate those fiddly branch offsets. Force-Push: yes Change-Id: Ifde20e2f8e405da3d74175fd029d589eb0a1ecc0
2026-04-13fix "describe" to work on both data segment and heapIrene Knapp
the hard part was figuring out the generic test for docol. it doesn't really test for docol, it tests for self-codewords and treats everything else as if it uses docol... not ideal, but good enough for now this also involved hardcoding the name "0branch" as an alternative to "zbranch". again, not a long-term strategy, but the long-term strategy is to remove flatassembler entirely, at which point the old names will go away because we'll be using our own lexer. there were also a couple small code-validity things that either broke the "describe" output, or became evident because of it, which are now fixed as well. Force-Push: yes Change-Id: If6641bb27f4fb0308f6fd4a2f4885215187ec8d9
2026-04-13stop heap implementations from referencing the data segmentIrene Knapp
there were a few places where this was inadvertently happening, mostly due to using the wrong name for things this should be all of them, based on searching the debug output for references to the wrong memory area Force-Push: yes Change-Id: I2023e3986f6ab15ff394cca759af3cb98c8ee923
2026-04-12add heap implementations of all remaining Forth-assembly instructionsIrene Knapp

and define the ones related to Forth assembly Force-Push: yes Change-Id: Iae63e3e4875d6c66222f903f904bd46c00dfd40a
2026-04-08heap impls of the dot and pow stuffIrene Knapp
also, they're topologically sorted now, and the map is up to date these are Forth words, so their binary forms aren't checked Force-Push: yes Change-Id: I4738ae562d0ceb327396298a29598988453a0756
2026-04-08heap impl of stringcmp, also a couple more Forth asm wordsIrene Knapp

2026-04-08add heap implementations for more assembly string opsIrene Knapp
also add Forth words for a couple missing assembly instructions the map is kept carefully up-to-date through this, and the binary output of the new implementations was checked against the binary output of the original implementations using the new dictionary-debugging feature Force-Push: yes Change-Id: Icc8666dc0da9697ccab5d235b714efaa9bdba113
2026-04-08implement the new assembly-based words that needed heap implementationsIrene Knapp
Force-Push: yes Change-Id: I5afdff11ce6003deaeae5a9a0844596a593bd393
2026-04-08reorder things to better separate "early" stuffIrene Knapp
Change-Id: Ieba5e3fb7eca5be769cbf798eac0b91e31a1fe75 Force-Push: yes
2026-04-08update the "map" of stuff that needs to be copied to the heapIrene Knapp
a lot of small utilities got added or reorganized as part of writing the debug code. the map now reflects the current state both of what's been implemented in flatassembler, and what has a copy-to-heap implementation Force-Push: yes Change-Id: I749cd1814e4b9e5360b68a77461849b345b16559
2026-04-08change guess_entry_end_in's behavior for inputs that don't existIrene Knapp

2026-04-07it now completely prints out its own source, backwardsIrene Knapp
if it were Mr. Mxyzptlk, it would now be vanquished Force-Push: yes Change-Id: I7af53bc2a2f5ab69850d9b8bee152c27d1878dc4
2026-04-05add width-padded variants of dotIrene Knapp

under the new names dothex and dotbase Change-Id: I783ad04c6eda1d607cef794788f7e09586650984 Force-Push: yes

2026-04-05implement dot, the function that prints an integerIrene Knapp
Force-Push: yes Change-Id: I3e282f1d850dac1ee31fc8ee55ba6edecdacbfca
2026-04-05implement logfloor and logceilIrene Knapp
the comparators were all backwards; that's fixed now. it wasn't caught before because eq and ne are commutative, and of the others, only lt had ever been used, and only in one place Force-Push: yes Change-Id: I0a44f8abd21dfc8e0327441d8009e5150ea220da
2026-01-13exponentiation wordIrene Knapp
and a placeholder for integer printing Force-Push: yes Change-Id: Ie147f3010820ef740405bba9a932d1ae6067b49a
2025-12-22disassembly stuffIrene Knapp
this will pave the way for the copy thing currently it correctly prints out all the actual codeword pointers that are part of the word it's scrutinizing, but it has a placeholder for integers the hard part of this was figuring out the start and end addresses; the iteration was also kinda fiddly Change-Id: I2bb8d7c768ffc4d3d1d2afd83d1fd2227d15cbae Force-Push: yes
2025-11-29add words to find the next newer entry in the dictionaryIrene Knapp
these are fully debugged. they'll be used for the decompile-and-recompile copy logic Force-Push: yes Change-Id: I25ba5c5934fc3d181dadcfb4cce09727dbacf70f
2025-11-28add the code to traverse from execution token back to dictionary entryIrene Knapp
yay Force-Push: yes Change-Id: I21d21df017db6df3c1b60288f0b8c7270f01ded8
2025-11-28all the basic Forth words are implemented on the heap nowIrene Knapp
yay the assembly-defining words are still not Force-Push: yes Change-Id: I561a9304741f98d8f30209d3ba1c3bec9b84c950
2025-11-28reformat some word-on-heap definitions; change underscores to hyphensIrene Knapp
having chewed on it, we still prefer kebab-case Force-Push: yes Change-Id: I6ec87be808a4060599d052e8698d677dba7d0134
2025-11-28invoke the heap-based docol as part of the heap copyIrene Knapp
this adds an "execute" word, which makes execution tokens useful for something it also builds "emitstring" on the heap, at runtime, to test that that all works properly Force-Push: yes Change-Id: Ic59a489c0a035a4174db516aeef77e23c7d8528b
2025-11-28implement looking up words by name (wow!)Irene Knapp
also, fix strlen to not include the null byte Force-Push: yes Change-Id: Ifd95da1fc0cf7006df0a25278e03651d6185f037
2025-11-10implement stringcmp, with extensive commentingIrene Knapp
and a lot of other stuff necessary for that, as follows implement the "adc" and "sbb" instructions in flatassembler (there's no Forth implementation of them yet) implement "cmps8" in flatassembler; Forth already has a much more thorough suite of string instructions add Forth jmp_rel_imm8 and flatassembler jmp.rel.bimm unconditional jumps. they're nver used, it just seems like they should exist. split the disp8 case from the indirect case for the flatassembler implementation of register-to-register mov, to match how the Forth implementation works fix the name of mov.disp8.qreg.qreg, which had been incorrectly named mov.qreg.disp8.qreg. it's never called anyway. fix a citation for the MOV instruction; Intel's section numbers are confusing. Force-Push: yeah Change-Id: I53761a3487041c142ade1a82a8ab9a3f1129b853
2025-11-09implement the rest of the string instructionsIrene Knapp

missed that instruction. oops. well, we have it now. Force-Push: yes Change-Id: I22583d6c6bda3cb66ad67a69a644aeb777114085
2025-11-08added assembly-in-forth implementation of rollIrene Knapp
also fixed scalefield the testing bar we're applying for these next changes is that it runs successfully, we aren't actually calling the generated funcions yet. we'll need to invent some methodology for checking they're generated correctly. Force-Push: yes Change-Id: I820e5671d74fa3bd4342e5d5b26b867e053ba3ca
2025-11-08add workaround for 8-byte strings (yepppppp)Irene Knapp
