Instead, you want the full execution of the right tweak that nobody talks about. Here is a step-by-step guide to the "notthetweakthatyouwant full" approach—tweaks that seem irrelevant but solve real problems. What you think you want: -march=native -Ofast -flto=full What you actually want: A reliable build sandbox.
Why would someone publish or search for a tweak that is explicitly described as undesirable?
Execute this full tweak:
# Create an LFS build directory with memory limits mkdir -p $LFS/tweaks/full mount -t tmpfs -o size=8G tmpfs $LFS/tweaks/full This prevents the compiler from crashing due to running out of RAM during full LTO builds. It’s boring, but it works. The full version of LTO often triggers internal compiler errors on older hardware. The tweak you don't want? -flto=full . The tweak you should apply?
