 Alyssa Ross | I wonder what's up with autoconf in binutils on darwin | 14:19:50 |
| Alyssa Ross | It's needed because of a patch, but I wonder why autoreconf doesn't work. | 14:20:15 |
| Alyssa Ross | Tethys SvenssonUh, what's binutils-unwrapped-all-targets?
| 14:26:30 |
| Alyssa Ross | is that useful to you? | 14:26:35 |

| aleksana (force me to bed after 18:00 UTC) | Cannot merge branch 'master' into itself. For more information, see https://docs.github.com/get-started/writing-on-github/working-with-advanced-formatting/creating-diagrams#creating-mermaid-diagrams | 14:29:03 |
| aleksana (force me to bed after 18:00 UTC) | Not familiar with this | 14:29:16 |
 emily | GitHub updated Mermaid and it doesn't like our branch diagram now. | 14:31:06 |

Tethys SvenssonUh, what's binutils-unwrapped-all-targets?
it is in fact maybe exactly what they want, I think. | 14:31:37 |
| emily | Xen was doing overrideAttrs crimes on binutils for want of that too. antimemetic package. | 14:32:00 |

 Tethys Svensson | It's kinda useful. Some parts of binutils support building for multiple architectures at once. This is useful to e.g. get a single gdb binary that supports many architectures at once. | 14:46:22 |
| Tethys Svensson | However not all parts of binutils support building for multiple architectures at once. Specifically the assembler only supports building for a single architecture at a some (or perhaps architecture family, I'm not quite sure). | 14:46:58 |
| Tethys Svensson | In any case, no: this unfortunately won't solve mu problems | 14:47:08 |
| Tethys Svensson | Pwntools is already using a multiarchitecture-aware gdb. I don't quite remember, but it might also be possible to get a multiarchitecture-aware disassembler. But I'm fairly sure that there is absolutely no way to get binutils to build an architecture-away assembler. | 14:48:47 |
| Alyssa Ross | What does pwntools do with an assembler, as opposed to a disassembler? | 14:52:08 |
| Tethys Svensson | It's a tool and library for playing Capture The Flag competitions (hacking competitions). It helps you write shellcode and has a bunch of pre-written shellcodes for many different architectures | 14:54:06 |
| Alyssa Ross | I see, it helps you write things as opposed to just analyze them | 14:54:49 |
| Alyssa Ross | gas has a --enable-targets=all option? | 14:55:41 |
| Alyssa Ross | that's the assembler, right? | 14:56:03 |
| Tethys Svensson | Yes, that is the assembler. If you can actually get it to work I'm very impressed though. | 14:56:53 |
| Alyssa Ross | If it's supposed to work and doesn't, we probably need to talk to upstream rather than adding new packages… | 14:57:11 |
| Tethys Svensson | I wouldn't bet my life on it, but I have sunk multiple hours into getting a functional multi-architecture-aware assembler to work | 14:57:13 |

| Alyssa Ross | What went wrong when you tried? Build failure on runtime? | 14:58:39 |

| Tethys Svensson | From the gas README:
`--enable-targets=...'
This causes one or more specified configurations to be added to those for
which BFD support is compiled. Currently gas cannot use any format other
than its compiled-in default, so this option is not very useful.
| 14:59:29 |
| Alyssa Ross | Aha, okay. | 15:00:09 |
| Alyssa Ross | So is gas the only thing we'd need multiple packages for? | 15:01:47 |
