I thought of a way to not break it: enable the debug info generation machinery, including VTA and SFN, but discard those only at the very end if -g is not enabled. The downside is that it would likely slow -Og down significantly, but who uses it without -g anyway? -- Alexandre Oliva, freedom fighter https://FSFLA.org/blogs/lxo Be the change, be Free!
