| lkcl | toshywoshy, magic thank you | 12:15 |
| lkcl | toshywoshy, btw can you send a link to any public information to FundingBox, soon? so they can put it into their blahblah "this is a real person make the EU happy" documentation? | 12:33 |
| octavius | lkcl, for the NGI Pointer team foundation statement, NLnet doesn't count as an EU grant, does it? | 12:48 |
| octavius | reason I ask is point 2.b) of your example statement | 12:50 |

| lkcl | octavius, i have no idea what 2.b) is | 13:40 |
| lkcl | just send them a link to a CV and give them some reassurance that you exist. | 13:40 |
| lkcl | it's the EU-audit equivalent of "are you a robot" | 13:41 |
| lkcl | hello i exist (i am not a fake identity trying to scam the EU out of grant money) i have been working on Libre-SOC for NN months, here's some links online where you can confirm i do in fact exist | 13:42 |
| lkcl | i.e. you're not a fake person on a fake project trying to fleece the EU. like the fake farms which took so much EU Grant Money for such a long time that no Chartered Accountancy Firm will sign off on the EU's accounts. | 13:43 |

| octavius | also I copied out the text of that pdf doc you sent me into .odt format. If it will be useful in the future, I can upload it as a template | 14:22 |

| ghostmansd | lkcl, whay should we do with entries like `0b1000000000,,,,,,,,,,,,,,,,,,,,,,,mcrxr,X,`? | 14:45 |
| ghostmansd | minor_31.csv | 14:45 |
| ghostmansd | I'm trying to wrap get_svp64_csv et al. so that we have some nice pure-Python abstractions atop, so that we could re-use this stuff in sv_binutils and power_decoder | 14:46 |
| ghostmansd | Heck I cannot even recall how it works in sv_binutils now. I should've hit this, since sv_binutils also use get_svp64_csv. | 14:53 |
| ghostmansd | Ah yeah. We don't grab "unit" field in sv_binutils, that's why. And other fields happen to be set by get_svp64_csv magic. Sigh. | 14:57 |
| ghostmansd | lkcl, it would be great if you could guide me through PowerDecoder's opcode calculations but w/o all these Signal/eq/does_something stuff. :-) The tree_analyze is a difficult beast, I'm still struggling to undestand how it works. | 15:09 |
| ghostmansd | Let's assume that for any given instruction, I know the following: 1) the major opcode pattern (Subdecoder.pattern); 2) whether this pattern is with dashes (Subdecoder.opint); 3) which Subdecoder.bitsel to use; 4) which Subdecoder.suffix to use. | 15:11 |
| ghostmansd | That is, assuming I have an instruction entry from certain CSV via get_svp64_csv, and I know the Subdecoder in advance... do we have a simpler way to calculate the opcode without diving into Signal and its friends? | 15:14 |
| ghostmansd | The only simple and obvious thing is extra.csv: it uses the whole range (all 32 bits) and there '-' symbols are simply translated as zeroes, nothing special. I don't know what on Earth OP_SIM_CONFIG is, though: couldn't find anything in binutils. | 15:28 |

| lkcl | ghostmansd, treat it as a binary number, masked by bitsel. | 18:42 |
| lkcl | you shift it up by the start-point of bitsel | 18:43 |
| lkcl | and use the *full* range of start-end of bitsel as the mask | 18:43 |
| lkcl | so | 18:43 |
| lkcl | bitsel=(0:5) | 18:43 |
| lkcl | you would create a mask of (1<<(5-0)-1)<<0 | 18:44 |
| lkcl | bitsel=20:31 | 18:44 |
| lkcl | you create a mask of | 18:44 |
| lkcl | (1<<(31-20)-1)<<20 | 18:44 |
| lkcl | and that value 0b1000000000 you simply shift up by 20 | 18:45 |
| lkcl | yes, i described how to split out the entirety of create_pdecode() into a completely separate module | 18:45 |
| lkcl | ignore extra.csv. its contents cannot be SVP64-prefixed anyway | 18:47 |

| programmerjake | intrinsics handling idea: lazily generate them, so even if there's 10M, we only pay for what we use which is very likely to be much smaller. patch for clang risc-v v which does that: https://reviews.llvm.org/rG7a5cb15ea6fa | 23:40 |
