JamieMagee	I found an issue with nixpkgs configuration of gdb, which doesn't match upstream configuration. Specifically, gdb doesn't support in-process agent on risc-v: https://github.com/NixOS/nixpkgs/pull/504872	03:41:58
misuzu	Try --cores 1	07:14:37
Alex	I had a build almost ending already, and this is what the RSS looked like just within 10s of the OoM kill: `436704 bin/c-index-test 4203668 bin/clang-tidy 2798596 bin/clangd-fuzzer` So yeah I think `--cores 1` is worth a try, though it'll probably take over 2 days to build a single `clang` version (and I need 2). 🫠	10:16:04
Alex	I have figured out a way to get LLVM linked with mold to evaluate (I think?) so I think I'll try that first.	10:17:01

Tristan Ross	When I was doing stuff with the VF2, I had to compile LLVM on 1 core. That took like 3 days to build.	16:42:12
Alister Galpin	In reply to @misuzu:matrix.org https://riseproject.dev/2026/03/24/announcing-the-rise-risc-v-runners-free-native-risc-v-ci-on-github/ This sounds awesome! Hate that it's GitHub but maybe an initial build+cache could work I remember hearing someone was setting up a cache?	18:16:55
