 trofi | Heh, Yeah. Looking at a change history of gcc/libgcc it looks like unwinder and new primitives get added all the time: https://gcc.gnu.org/git/?p=gcc.git;a=history;f=libgcc;hb=HEAD. It depends so much on the rest of the ecosystem: new CPUs, new C types (like float decimals, int128/256), atomics against them. Could be lucky not to break for years, or could get new symbols in veery single release. | 11:06:37 |
| trofi | WRT bootstrap defined as a sequence of stdenv/pkgs instantiations it feels like recursive definition does not encourage you to keep it lean. If somebody remembers to check if bootstrap got 10 new packages due to fresh automake in coreutils then lucky them. Otherwise it silently gets expanded with a bunch of seemingly auxiliary things. | 11:09:07 |

| trofi | Also drew a few pictures and arrows around bootstrap for general amusement if you are into that kind of thing: http://trofi.github.io/posts/275-nixpkgs-bootstrap-deep-dive.html | 12:40:35 |

Also drew a few pictures and arrows around bootstrap for general amusement if you are into that kind of thing: http://trofi.github.io/posts/275-nixpkgs-bootstrap-deep-dive.html just started reading, but the fact that libgcc_s.so comes from the bootstrap tarball was reported as an issue a long time ago https://github.com/NixOS/nixpkgs/issues/36947 | 12:48:07 |
| trofi | Yeah. I'm a nixpkgs noob. Was way before i popped up around :) | 12:51:01 |
| @andreas.schraegle:helsinki-systems.de | Don't worry, I've just been tangentially aware of a lot of these issues but never had the time&energy to properly try to fix them. Thanks for your work on this stuff. | 13:08:37 |

was this mainly the libtool stuff? | 02:57:17 |

nah It's a bit of everything. There is also recent lzip cleanup: https://github.com/NixOS/nixpkgs/pull/210727. And ideally we could lean bzip2 as well at some point: https://sourceware.org/PR30001. I think it's a last stand for autoconf.
The caveat is that I'd like to add an extra gcc build instead: https://github.com/NixOS/nixpkgs/pull/209063 :)

| trofi | binutils-2.40 update: https://github.com/NixOS/nixpkgs/pull/211126 . This time I threw away all of libbfd/libopcodes build system patching and used separate .lib output. | 18:23:35 |
