rewrote my contentdb CLI in shell! (also found that x0.at rejects files ending in .sh) https://x0.at/KAkA |

What was it written in before? |
| 03:06 |

python 3 |

Ah, sounds like you have a decently broad skillset. Wouldn't python be faster than shell? But I suppose shell is more readable/brief for this set of use cases. |
| 03:09 |

i chose shell because (a) POSIX shell is pretty fast, and it's on pretty much every linux/BSD (b) i'm much better at shell than python, so it was worth the loss of some features |

user333_: Now rewrite it in RISC-V assembly :P |

<Blockhead256> CISC rules |

D: |

* cheapie |
hides from Blockhead256 behind a wall of unusually CISC-like (by RISC-V standards) instructions, like amoadd.w and cm.popretz |
| 10:59 |
[MatrxMT] |
<Blockhead256> PCLMULQDQ, GF2P8AFFINEINVQB, YMMVDWYWDD2VD |
| 10:59 |
[MatrxMT] |
<Blockhead256> one of those is not an x86 instruction |
| 11:00 |
cheapie |
The last one, I think? |
| 11:00 |
[MatrxMT] |
<Blockhead256> darn you got me |
| 11:00 |
cheapie |
I keep meaning to get around to implementing Zbc (carry-less multiplication) in RVController sometime |
| 11:00 |
[MatrxMT] |
<Blockhead256> if you liked that, you may also like "C standard library function or Welsh word?" |
| 11:00 |
cheapie |
I think I have an idea for how to do it that wouldn't be incredibly slow |
| 11:05 |
cheapie |
Also I think if I get that one implemented, then that'll be every standard extension (and one custom extension) that Hazard3 can be configured with |

vluxseg3ei8.v and vfncvt.rtz.xu.f.w at Blockhead256 |
| 11:33 |
[MatrxMT] |
<Blockhead256> huh, RISC-V has dots as well |
| 11:33 |
cheapie |
Yeah, not in the base set, but lots of extensions do |
| 11:34 |
cheapie |
Even just sticking with what RVController supports, there are some that look... rather 68k. amocas.b/amocas.h/amocas.w/amocas.d come to mind |
| 11:34 |
cheapie |
RV64 adds an amocas.q to that |
| 11:38 |
cheapie |
C and related extensions get you prefixes too, 'c.' for instructions that map to one 32-bit instruction or 'cm.' for ones that map to multiple |
| 11:46 |
cheapie |
Just how many? cm.popretz {ra,s0-s11},112 (on RV32) expands to: lw s11,0(sp) | lw s10,4(sp) | lw s9,8(sp) | lw s8,12(sp) | lw s7,16(sp) | lw s6,20(sp) | lw s5,24(sp) | lw s4,28(sp) | lw s3,32(sp) | lw s2,36(sp) | lw s1,40(sp) | lw s0,44(sp) | lw ra,48(sp) | addi sp,sp,112 | addi a0,zero,0 | jalr zero,ra,0 |
