11 daysexplanatory text at the start of the hex transformed label transform codeIrene Knapp
Force-Push: yes Change-Id: I695582905dea0c6e34981e803ef515c547eade40
11 daysswap the order of parameters to hexdump-betweenIrene Knapp
it was confusing from the start, and we had one too many issues with failing to remember it. finally taken care of :) Force-Push: yes Change-Id: I9782621f747e84d50d1794e3f1669cb5afb77038
11 daysfully verify the hex-transformed output of all Evocation-assembly wordsIrene Knapp
the verification included words that aren't used in Evocation itself. it also resulted in fixing several such words that were broken in ways that would have crashed. it was a very thorough verification. do honor to the effort that was put into it by always verifying that changes to amd64.e don't break it, from now on :) Force-Push: yes Change-Id: Ia1904f4b35f90772fd9dce79a0274627c547edbf
11 daysremoved the #swap syntaxIrene 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 dayssemantic change to make subitem stack manip more convenientIrene Knapp
this allows a much cleaner style than the #swap notation, which will likely be removed soon Force-Push: yes Change-Id: If9898334356eb7c036f28afd22d435e00a84f6e2
13 daysrefactor the metadata postprocessing a little for readabilityIrene Knapp
there's about to be a semantic change, but that will happen in a separate CL Force-Push: yes Change-Id: Ib32d542c02a640a964fdeed7bc16248b669d6a91
13 daysbegan to check and correct the exact hex-transformed instruction outputIrene Knapp
the checking is only a little way down the file, but there's a new feature needed, so this is being checked in now to protect the work that's already been done Force-Push: yes Change-Id: If8c29d4b417288e5cfb2aa08ce6d41adadc64279
13 dayssubstantial additions to the READMEIrene Knapp
and also a prettier flame drawing Force-Push: yes Change-Id: I5896bfdee53c934b4c38861c8a9e9f5a966f7264
13 daysrename substring entries to subitem entriesIrene 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 daysadd provide-hex, which varies its output width to fit the valueIrene 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 daysadd some magic comment commands to reorder subitems more generallyIrene 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 daysstatus update in the README! an important one :)Irene Knapp
Force-Push: yes Change-Id: Ia929bd55a0cec2781a4166dad4c7797fd2cb1b9d
14 daysfix all leaks and incorrect parameter counts in amd64.eIrene 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 daysdocument how to do a full build of evoke.hexIrene Knapp
the contents of evoke.hex aren't usable quite yet, for reasons now described in the README, but the build itself runs to completion. this is honestly a huge milestone. Force-Push: yes!!!!! Change-Id: Ia95d6aba7485062c0e64cdde0575058a2df2a1ef
14 daysdeal better with return values when underflowing the substring entry stackIrene 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 daysfix broken compile with the flatassembler versionIrene 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 daysprovide word entries for "here" etc inside the hex transformIrene Knapp
this replaces the alternates we previously had for those words Change-Id: Ia8c8ca7203e03f511d68a30811fb8a5d262c6312 Force-Push: yes
2026-09-09fix strings under the hex transformIrene 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
2026-09-09check in the hex binary and commented hex-dumpIrene Knapp
yes, wow, right? big milestone! doesn't work for evoke itself quite yet, but getting really close Force-Push: yes Change-Id: I1e836b85cf185db4aa835d2aa494a67585e60744
2026-09-09add an implicit way to define suffix commentsIrene 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
2026-09-09rename the provide-substring-* entry types to push-substring-*Irene Knapp
Force-Push: yes Change-Id: I2d0ed253fc7b0e38f63cb0e6290ac2b1a64e32e8
2026-09-09provide a #swap operation in comment templatesIrene Knapp
and use it in a couple places in amd64.e where it's needed Change-Id: Id73dcd13f08c03aa02ac09e45ab034fcd90f2569 Force-Push: yes
2026-09-08handle the rest of the fields (keywords and numbers) in amd64.eIrene 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
2026-09-08add keyword support to magic comment templatesIrene 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
2026-09-08add "provide" words for all sizes of hex literal, and use them in amd64Irene Knapp
Force-Push: yes Change-Id: Ibdc4e05f8c63f0b4b6b8e504f89e053e6cd3a912
2026-09-08substring substitution works nowIrene Knapp
now to build out a variety of kinds... Force-Push: yes Change-Id: I331c3275c9705cacd7f634506b93d05085458754
2026-09-08hex-transform comment output now goes through a lexerIrene Knapp
this will be used to substitute substrings, but that's not wired up yet Force-Push: yes Change-Id: I957ac153599b02ca8cdc46c7cb2ec487aa2af31c
2026-09-08bubblesort the metadata entries during postprocessingIrene 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
2026-09-08the hex dump now prints trailing messages at the end of the dataIrene Knapp
Force-Push: yes Change-Id: I71930b088c176ade6a0bf7aaecb46bdecb0636ad
2026-09-08add support for more prettiness features in the hex-transform's outputIrene Knapp
suffix comments can now have a negative length, which makes them cover a span anchored with the current point at its end rather than its start magic comments can now request the suppression of metadata entries that would otherwise be generated everything in elf.e has magic comments now Force-Push: yes Change-Id: I409982afdd346c2ecf91e4c24f96ca81f887b126
2026-09-08horizontally align suffix commentsIrene Knapp
Force-Push: yes!!! Change-Id: Ib8306fc0924445bb70538011bdbc4b3fca3a6865
2026-09-08add magic comment length tracking to all the amd64 instructionsIrene Knapp
yay! Force-Push: yes Change-Id: Ib54458c2466362391cc8724ad8af32f03a869e03
2026-09-08create a new magic-comment command that mutates a previous entryIrene Knapp
this allows the length of a metadata entry to be adjusted after it's created, which simplifies the implementation of instructions that might vary in length Force-Push: yes Change-Id: I0889dc8b5a4f19adbb1f8ec0d5733a0310457766
2026-09-08add suffix comments which come at the end of a lineIrene Knapp
this may be the most important feature for pretty output there aren't actually any yet (though this has been tested), because there's another feature needed to make them useful Change-Id: I4ad26a5815e3ffbc64eddd8c813c6eee6d2e989a Force-Push: yes
2026-09-07add indentation and blank lines as magic-comment featuresIrene Knapp
the output is really starting to look like something! Force-Push: yes Change-Id: Ic41c8b1702d884ff89693a86d457af7cc752aa86
2026-09-07add tracing of the latest output point in packstringIrene Knapp
this is necessary because packstring isn't implemented in terms of pack8, unlike packalign also add a bunch more magic comments to hex.e, which would be in the wrong place without the semantic change Force-Push: yes Change-Id: I422b8d00a07568be5113e005fddaeab82f5ca731
2026-09-07add magic hex-transform comments in all the amd64 instruction wordsIrene Knapp
also add logic to output newlines at the start of these comments Force-Push: yes Change-Id: I4c3ce99c264e7d02150cdf2b40d486e925b5fb72
2026-09-07implement magic hex-transform commentsIrene Knapp
they work! that is, they show up in the output. to prove it, two of them are added to elf.e. they don't yet deal with substring parameters, and there's some formatting niceties to consider. Force-Push: yes Change-Id: I0a0f72e21ca023bf99287880d52b5a8dddbf8e34
2026-09-07create a special comment syntax for the hex transform's useIrene Knapp
right now all we do is recognize the special comments and save their body text for later handling. in a future CL, hex-tilde-replacement will turn them into output metadata entries. Change-Id: I53cc9d0cd781c2fc43af180ae98606efc14c3147 Force-Push: yes
2026-09-07add traps to all the pack[0-9]+ wordsIrene Knapp
this is probably not going to be used in the end, but we found it necessary to write it out to get in touch with our feelings, which allowed us to decide on the other approach, and it's a small amount of code so it's probably best to leave it in until the transform is done. if we took it out we'd keep being tempted to put it back. Force-Push: yes Change-Id: I431d27d4f8b8e5415d84d0a2752a0522639792e9
2026-09-05do some stack walkingIrene Knapp
this isn't directly useful yet, but it helps build intuitions about what kinds of situations the hex transform needs to be able to annotate Force-Push: yes Change-Id: I5607649df2db38eeb17d486d5117b07d0b9d03ef
2026-09-04extensive commentary about the memory assumptions of the hex transformIrene Knapp
seriously there was a lot to write here. so, it's going as its own CL. Force-Push: yes Change-Id: I1ff091214012fb7c5f0d046f27f0b9f7b3e11ee3
2026-09-04add a generic trap to the hex transform that traces every call to a Forth wordIrene Knapp
the trap doesn't do anything yet, except print some diagnostics, but it installs correctly Change-Id: I3ab9c2eef93167849821791f08188e57a042891f Force-Push: yes
2026-09-03comments: document trap methodology; rename parameters to packalignIrene Knapp
"alignment byte count" was confusing since it could mean either the input value that should be used as the modulus base for the desired byte offset, or the number of bytes actually needed to attain modulus zero under that base. in "packalign" itself, this wasn't too confusing, but the hex transform's trap of packalign needs to work with both values alongside each other, so the name needed to be clearer. it is renamed to "alignment byte width". of course, Evocation doesn't have parameter names as-such, this is just a comment thing Force-Push: yes Change-Id: I1c227200ce0b2f6a852c1dc2f2c73f8cdf474f7a
2026-09-03hex transform of packalign now implementedIrene Knapp
hex.e doesn't actually call packalign, so this was tested by temporarily modifying it to do so (not checked in) Force-Push: yes Change-Id: Ie266c3bda6e65e055da5d88acfe248d6487ab6cc
2026-08-30distinguish different types of metadata entryIrene Knapp
so that each can have its own formatting Force-Push: yes Change-Id: I59b2eb556b9c1ab1c71118077073b7a8650ed33b
2026-08-30significant reduction of raw access to the metadata structureIrene Knapp
Force-Push: yes Change-Id: Ibdf713ba0e66c7a3b4632dacdfa7f10733112b0a
2026-08-30add some stuff about string literals to the readmeIrene Knapp
Force-Push: yes Change-Id: I7bda5d1ad0c6b1b44ea283b429b14fd397ef978a
2026-08-30output hex transform comments giving the readings of string literalsIrene Knapp
this is gonna work!!!! we can feel it!!!! Force-Push: yes!!!!! yes, oh, yes! but in an asexual way Change-Id: I883ad1fb63aa73b753644c9f91bfa46a3d83d2f3
2026-08-30add a buffer-start field to the hex output metadataIrene Knapp
Force-Push: yes Change-Id: I07e8170c88952bd3d490341db777f4e102da4acd
