@switch3flip:matrix.orggluonix as you may know, nix has a steep learning curve, hence most dev teams prefer docker, unless they have no choice 😆 01:03:01

@p14:matrix.orgp14I know there was some interest in having a PGO/LTO/BOLT clang build, as well. Some notes on build reproduciblity when PGO is involved: https://discourse.llvm.org/t/pgo-profile-reproducibility/82861/6 TL;DR: For profiles it is not enough for the profiling mechanism to be deterministic and the workload to have a deterministic output; the workload must compute the output in a flow-control deterministic way. Clang unfortunately uses inodes in a hash map, which makes the profile not reproducible, so it's not currently possible to have a reproducible PGO clang build. (Unless you control the inode integers that clang sees during profiling, among other horrible details).11:41:38
