17 hours	all the syscall parameters are in the kernel's order now	Irene Knapp
	there was never a good reason for them not to be plus, the formerly bespoke ones use the generic helpers now; sys-open and sys-close are implemented; and a bug in push-input-buffer and pop-output-buffer is fixed unfortunately these were breaking changes, so there's another evoke.hex in this one Change-Id: Ifad58fc2fd757adcf89a69c59575565a10406ec2 Force-Push: yes
40 hours	change sys-write and sys-read to take file descriptors	Irene Knapp
	and also sys-write didn't used to return a result this required a little massaging to make it build, the host evoke needed to not actually pass the file descriptor in evoke.e. for posterity: this was fixed by changing it everywhere else as a one-off, then changing it there and using the intermediate version to build the one being checked in now. this kind of weirdness is a thing we get the freedom to do because of the bootstrapped distribution model, though we still strongly prefer not to do it unless necessary. this breaking change would have had to happen at some point, so it's considered acceptable. the size of the diff to evoke.hex is larger than ideal. this raises the need to have a policy for when to regenerate it. since this is a breaking change, it's mandatory. it also seems important to commit a regenerated copy when a release is tagged. it will probably turn out to be a good idea to not regenerate it excessively, otherwise. it's possible that in the long run it might make sense to add name-mapping functionality to hex, just to make the diffs smaller. Force-Push: yes Change-Id: I2648b2577c5c21b126e46405e9888b5cb59aa0b7
3 days	print comments in the hex dump at the offsets labels point to	Irene Knapp
	Force-Push: yes Change-Id: I1a0ea06380095da3e7702cab278c08bd21b292ca
3 days	no more than sixteen bytes on a line	Irene Knapp
	Force-Push: yes Change-Id: I7cd583d5a3ee72c316633ceb2efbb51a2fe46452
3 days	make the magic-comment tab stops function like real tab stops	Irene Knapp
	fun! fiddly! :D fixing one-off column alignment issues is like stimming for coders (which is to say, like stimming) Change-Id: I1037ec27b863f90117fb22a29ef52d0ba460c7d5 Force-Push: yes
3 days	add a special word for magic-comment tab stops	Irene Knapp
	Force-Push: yes Change-Id: I7ba182f5939aa3b5d280fb48673e2cc74d72e8ea
4 days	magic comments work in the log-load transform now	Irene Knapp
	that was pleasingly straightforward Force-Push: yes Change-Id: I92b66fbb37ed5df3ef3f733e8679747a9a232373
4 days	every byte in the hex output is now attributed	Irene Knapp
	wow!!!! Force-Push: yes Change-Id: I2b46837b5ff37b4339a9a4ba0ae52903854d5e99
4 days	indent curly-brace blocks in the log-load transform hex output	Irene Knapp
	Force-Push: yes Change-Id: I18e04f06390e85d4cd2c113094a137986ca2e54a
4 days	some basic indentation for parts of the log-load transform	Irene Knapp
	Change-Id: Ibfd4fa69a3d2abdaba162538f6386f7173af4311 Force-Push: yes
5 days	codeword annotations and such for the log-load transform	Irene Knapp
	this is everything outside of log-load-transform-one itself compile time is up to nine minutes though, due to the new backwards-scan thing. keeping the entries sorted might be better... Change-Id: I96058f0c9c043f7b8b681018e1178505caddbc62 Force-Push: yes
5 days	magic comments for all the high-level flow control in the label transform	Irene Knapp
	Change-Id: I5430e14e81c5981f358fda43c2f35ed47cafc29b Force-Push: yes
5 days	add a bunch more data- and entry-manipulation magic-comment commands	Irene Knapp
	now it's possible to make ;asm replace "docol codeword" with "self codeword", and it does Force-Push: yes Change-Id: I1a9b4cee8a3eee308cf421968d6a3cd92adba800
5 days	a new "data" concept in magic comments	Irene Knapp
	this is meant to handle variable-length stuff. it is now used to handle the string in the word entry headers. Force-Push: yes Change-Id: I8f3ce7dd93351639fbce82503324f3efe5def568
5 days	magic comments for a bunch more small stuff	Irene Knapp
	especially in the label-transform output there's more to do, but there are additional magic-comment features that would be handy, so we're checking this in now so that those can be cleanly kept in their own CL Force-Push: yes Change-Id: I97a67caddc3f3150c349b7956c1d715db909d1a9
6 days	give the names of codeword pointers in label-transform output	Irene Knapp
	under the hex transform, that is this also implements ndrop in quine, because it wasn't building evoke, and it checks in the updated hex.hex which reflects the more concise notation for integer constants. this brings all the builds into a clean state, for the moment. Force-Push: yes Change-Id: I243cf08c70b4a3af00ea5e0836c5596a32f1288b
6 days	handle memory sliding in the hex transform	Irene Knapp
	wow!!!! that was big Force-Push: yes Change-Id: I504ae746d4424e46819357e6dad6d6eadec16b81
8 days	yeah okay, copying it wasn't necessary	Irene Knapp
	Force-Push: yes Change-Id: I9772f90f497a19c04ff6f9e261a5d9f262f79be7
8 days	fix the overwritten strings in the output	Irene Knapp
	this probably shouldn't have required copying them, but ah well, copying worked Force-Push: yes Change-Id: I239f2633c61867f6c42a5b76a0e978aff0875a9d
8 days	redo the hex dump comments for alignment to use the regular magic commands	Irene Knapp
	previously, alignment had been a special-cased type of metadata entry, with a special trap on packalign. now it uses the same programmable setup everything else does. much simpler, and prettier output. this CL also contains some modest reformatting of section headers in the hex dump Force-Push: yes Change-Id: I21554e92f6af6ddefa937dad8073b89657f85d64
8 days	added section headers and other formatting to all the parts of the hex dump	Irene Knapp
	Force-Push: yes Change-Id: Ie66d85fd171dfb45d1f3b6869bf94056ec8303af
8 days	do magic comments from the label transform when inside the hex transform	Irene Knapp
	the meaning of them in that setting is a bit different, which deserves to be documented eventually Change-Id: Ia7725bc776420c0ad62091a2e5100700868a6bfa Force-Push: yes
8 days	oops, didn't mean to comment that out	Irene Knapp
	Force-Push: yes Change-Id: I8fbf3d531b18904f2a01e6b05ff2822d6a015013
8 days	refactor hex-tilde-alternate to split out lexing	Irene Knapp
	note that lexing of the body of a magic comment was already separate, part of hex-tilde-replacement. however, hex-tilde-alternate had been responsible for lexing the sequence that introduces a magic comment. because we want to make separate versions of the alternate for each inner transform, the lexing needed to be factored out. this does result in more copying, but it doesn't appear to noticeably affect runtime. Force-Push: yes Change-Id: I51a780d1dadb99f09bddb9eaccb1af387bd0ce87
9 days	avoid repeated scanning of the metadata entries during formatting	Irene Knapp
	there was a test that had never been working, meaning the entire entry array was being scanned for every byte of output. even had that test worked, it would still have scanned on average half the array for every byte, so that'd be where the absurd runtimes were coming from. anyway, it works now. this gets a full hex transform invocation down from over thirteen minutes to under thirty seconds. learn your data structures and algorithms, kids. Force-Push: yes Change-Id: If075b256f77649fae9d2e56cb7404458ca39d189
9 days	place a trap inside the hex-transformed nlabel-transform-one	Irene Knapp
	this will be used to cause it to apply a tilde alternate, but the lexing code for that needs to be refactored first also, this has an implementation of nexit, a new flow-control word for a scary style of metaprogramming Force-Push: yes Change-Id: Ic7fe2d50a8ee21cf9fa5fef1fef4408c2935bb4c
9 days	add the ability for magic comments to happen in immediate mode	Irene Knapp
	but, don't do them, though, they aren't ready yet. for reasons described in the code. they're harmless, they don't cause crashes or incorrect output, they just don't cause any output at all. Force-Push: yes Change-Id: I5e45adc60f4e01e7bc54d9da8aa4fa5f8b708ddb
11 days	work on making the label transform pretty-print word entry headers	Irene Knapp
	this involved instrumenting label-create-alternate and some other stuff it also involved adding provide-string and provide-string-copy magic-comment commands Force-Push: yes Change-Id: I52f87decc02bf6f2516ee009f27c783a2c5bd715
11 days	explanatory text at the start of the hex transformed label transform code	Irene Knapp
	Force-Push: yes Change-Id: I695582905dea0c6e34981e803ef515c547eade40
11 days	removed the #swap syntax	Irene Knapp
	everything has been carefully diffed to ensure there's no regression in the verified parts of the output Force-Push: yes Change-Id: I32c887c7ca8c132a49899d9ef327c8ff9fb782fb
11 days	semantic change to make subitem stack manip more convenient	Irene Knapp
	this allows a much cleaner style than the #swap notation, which will likely be removed soon Force-Push: yes Change-Id: If9898334356eb7c036f28afd22d435e00a84f6e2
13 days	refactor the metadata postprocessing a little for readability	Irene Knapp
	there's about to be a semantic change, but that will happen in a separate CL Force-Push: yes Change-Id: Ib32d542c02a640a964fdeed7bc16248b669d6a91
13 days	rename substring entries to subitem entries	Irene Knapp
	also the -entry-string field is renamed to -entry-content, since it's an integer a lot of the time much clearer. hopefully. certainly more consistent. Force-Push: yes Change-Id: I82315a135422ef2fae5dd3d6e8ea025ccfa97cfd
13 days	add provide-hex, which varies its output width to fit the value	Irene Knapp
	and amd64.e uses it for all the immediates, but not for other kinds of numeric parameter, which looks pretty slick and readable Force-Push: yes Change-Id: Ifb630a4dc172d7495b5458316266fe76b75e07af
14 days	add some magic comment commands to reorder subitems more generally	Irene Knapp
	these are all fully working and debugged. they have been used in a principled attempt to get all the parameter orders in amd64.e correct, but that effort needs to be verified carefully, which it hasn't been, yet. a couple of missing magic comments in elf.e and execution.e were also added. Force-Push: yes Change-Id: Id4c48b121a71b4f945ee3718e14a06f07afd7304
14 days	fix all leaks and incorrect parameter counts in amd64.e	Irene Knapp
	this required adding a new magic-comment command, drop-subitem, because there's a couple cases, in indexed addressing mode helpers, where a hardcoded register value is used as part of preparing an sib word, and that value shouldn't become a subitem for the assembly word that calls the helper. notably, a lot of the disp8 and indexed assembly words had incorrect parameter counts that needed adjusting parameter ORDERS still need a close read to make sure they're correct. also, as future work, substring entries should be renamed to subitem entries. Force-Push: yes Change-Id: I419243855751416377d0ea0c5062fa1ba9e62a8d
14 days	deal better with return values when underflowing the substring entry stack	Irene Knapp
	it's now able to run all the way to the end of the label transform, inside the hex transform. the output leaves much to be desired, but it runs. Force-Push: yes Change-Id: I7cac39df599e8081fac6b050dfeb34e598bb54eb
14 days	fix broken compile with the flatassembler version	Irene Knapp
	oops. that was a good catch, should have been checked more often. hopefully it won't be needed much longer. Force-Push: yes Change-Id: I3e2d04118a6f588c410e2439fbbd52aabd173e77
14 days	provide word entries for "here" etc inside the hex transform	Irene Knapp
	this replaces the alternates we previously had for those words Change-Id: Ia8c8ca7203e03f511d68a30811fb8a5d262c6312 Force-Push: yes
2026-09-09	fix strings under the hex transform	Irene Knapp
	this is towards being able to run the hex transform on Forth compilations, rather than just assembly compilations like it does right now. it's been verified that it doesn't cause any regressions. the reasoning for why this fix is necessary is complex, but explained fully in comments I have to admit that I'm not totally clear why the unmodified, untransformed string words don't work for this scenario, but they don't, so... Force-Push: yes Change-Id: I93640c7ca965eba5dc28116bda0165ae1c941458
2026-09-09	check in the hex binary and commented hex-dump	Irene Knapp
	yes, wow, right? big milestone! doesn't work for evoke itself quite yet, but getting really close Force-Push: yes Change-Id: I1e836b85cf185db4aa835d2aa494a67585e60744
2026-09-09	add an implicit way to define suffix comments	Irene Knapp
	and make the explicit way more versatile (allowing zero length) this required hooking the lexer at a pretty low level, but it worked out fine Force-Push: yes Change-Id: Icdbe233fbf9d4cf07cb8d03975eed3b4f7b620aa
2026-09-09	rename the provide-substring-* entry types to push-substring-*	Irene Knapp
	Force-Push: yes Change-Id: I2d0ed253fc7b0e38f63cb0e6290ac2b1a64e32e8
2026-09-09	provide a #swap operation in comment templates	Irene Knapp
	and use it in a couple places in amd64.e where it's needed Change-Id: Id73dcd13f08c03aa02ac09e45ab034fcd90f2569 Force-Push: yes
2026-09-08	handle the rest of the fields (keywords and numbers) in amd64.e	Irene Knapp
	add a provide-decimal variant of the magic-comment provide command family note that the fields are all printed in a wrong order, at present Force-Push: yes Change-Id: I01f5cbb86f61e78ce652c54fc8b29b88efd1b2b6
2026-09-08	add keyword support to magic comment templates	Irene Knapp
	additionally, handle many (not yet all) of the keywords used by amd64 words this exposed an existing flaw in the metadata entry processing, which is now fixed as well. to wit: it's common for provide-substring entries to come after the comment entries they go with in the entry array, but this is valid because adjust-length commands can edit the length field of the comment entry afterwards, and the comment entry will be moved to after the provide-substring entry based on its final length, but this can't happen if the adjust-length array isn't able to find the comment entry it goes with, which may not be the most recent entry. so, the adjust-length command needs to scan backwards to find the most recent comment entry, not just the most recent entry. confused? don't worry... this CL includes documentation. wow. that was a lot. Change-Id: I01c574fca020fd2e3adaf335267264fdbc8b87f1 Force-Push: yes please
2026-09-08	add "provide" words for all sizes of hex literal, and use them in amd64	Irene Knapp
	Force-Push: yes Change-Id: Ibdc4e05f8c63f0b4b6b8e504f89e053e6cd3a912
2026-09-08	substring substitution works now	Irene Knapp
	now to build out a variety of kinds... Force-Push: yes Change-Id: I331c3275c9705cacd7f634506b93d05085458754
2026-09-08	hex-transform comment output now goes through a lexer	Irene Knapp
	this will be used to substitute substrings, but that's not wired up yet Force-Push: yes Change-Id: I957ac153599b02ca8cdc46c7cb2ec487aa2af31c
2026-09-08	bubblesort the metadata entries during postprocessing	Irene Knapp
	since we do this here, we no longer need to worry about doing it during initial entry creation, so that's good. that had been on the mental "maybe later" checklist for a while. the various innovations in entry processing now make it possible to pass through most of the formatting in hex.e, so that's done now (suffix comments that aren't instruction decodings still need to be made to work) there's also a new entry type which will be part of the comment parameter system. that's not fully working yet, but this was a bunch of really subtle debugging, so it makes a good spot to checkpoint at. Force-Push: yes Change-Id: I2aff7276368eaad7e5c280a58834605e294dcd74
