| programmerjake | ghostmansd: you should be able to copy the values for `darn` from: https://github.com/antonblanchard/microwatt/blob/de8fd492c8909f45f83a4cbbb5993156a5077b1c/decode1.vhdl#L238 | 11:50 |
| programmerjake | that's where the csvs originally came from | 11:51 |
| ghostmansd | Yes, I know this was generated. | 11:51 |
| ghostmansd | How about having a list of identifiers to be skipped? | 11:51 |
| ghostmansd | Likely in the same place where CVSs reside. | 11:51 |
| ghostmansd | Sorry, but hard-coding these in the code is a really bad option. | 11:52 |
| programmerjake | i meant you could take the values from the line i linked and use them to fill in the csv fields... | 11:52 |
| ghostmansd | Don't we have a generator for this? | 11:54 |
| ghostmansd | I mean, if we generated the file, shouldn't we keep generating it from decode1.vhdl? | 11:54 |
| programmerjake | yes, but it goes the other way, from csv to vhdl | 11:54 |
| programmerjake | we started from decode1.vhdl then edited it by hand | 11:55 |
| programmerjake | edited the csv | 11:55 |
| ghostmansd | So we took decode1.vhdl, then generated the CSV, then edited it? | 11:57 |
| programmerjake | yup | 11:57 |
| programmerjake | iirc | 11:58 |
| ghostmansd | Why don't generate this CSV from VHDL and at the same time have some special CSV which only overrides entries which need to be overridden? | 11:58 |
| ghostmansd | Changing the artifacts (and this includes the generated code) is a really strange option. | 11:58 |
| ghostmansd | I guess at some point there was no darn insn in decode1.vhdl, right? Is it why this was added in CSV? | 11:59 |
| programmerjake | yes, we converted before darn was added | 11:59 |
| ghostmansd | If we haven't touched the generated artifact at all and simply had a custom CSV, that one would be a great field for experiments. | 12:00 |
| programmerjake | original commit: https://git.libre-soc.org/?p=libreriscv.git;a=commit;h=f1b3aff57eed74fd8b7afb74de84b562778518eb | 12:01 |
| ghostmansd | And perhaps we even could restrict custom CSV with only new names. That is, when the code opens the generated CSV and a custom one, it could check if a custom CSV tries to update the insn already present in the generated one. | 12:01 |
| ghostmansd | But OK, I will skip these entries for now. | 12:02 |
| programmerjake | lkcl would know if he still has whatever script generated the csv lying around... | 12:02 |
| ghostmansd | Still this is bad, because it's silent and non-obvious, and requires a manual intervention and intimate knowledge of the sources. | 12:02 |
| ghostmansd | One of rules I've constantly been sticking to is never EVER edit the autogenerated files. | 12:03 |
| programmerjake | yeah, we definitely need more error checking...if we were using rust this would be more likely to be error checked because we'd just parse it into a struct... | 12:04 |
| programmerjake | serde's pretty awesome in that respect | 12:04 |
| ghostmansd | Well, basically all the recent comments are caused by the fact I started adding these checks | 12:08 |

| octavius | lkcl, the Pin class doesn't include the bank information. Should I add a parameter to indicate the bank (0/1/2/3)? | 14:13 |

| markos | programmerjake, iirc you pasted a list of RVV intrinsics some time ago, but I cannot find the link, it was probably in jitsi, would you mind sharing this again? or even better a parsable/mineable file with the full intrinsics list? | 16:03 |
| markos | or rather a link to that | 16:04 |
