The sooner people make their peace with this, the better. Yep. It fights with time preferences as well: when I tried building gcc6 "full bootstrap" via poudriere cross- builds on amd64 (4 cores/threads used) and native on a bpim3 (-mcpu=cortex-a7 with 4 cores supported by FreeBSD and 2GB if RAM) the native build was much faster as I remember. Of course once the cross build was using the gcc6 internal bootstrap compiler not much was running native cross-toolchain materials. (Building that internal bootstrap compiler did have a native-clang cross-compiler involved.) [I do not have access to server-class thread counts or RAM either. And the non-multithread stages contribute even in those contexts as well.] So I'm not looking forward to the issue from that point of view. === Mark Millard markmi at dsl-only.netReceived on Thu Mar 30 2017 - 18:54:21 UTC
