There was a problem hiding this comment.
So the cargo.toml.example says:
# Indicates that the build should be optimized for debugging Rust. Note that
# this is typically not what you want as it takes an incredibly large amount of
# time to have a debug-mode rustc compile any code (notably libstd). If this
# value is set to `true` it will affect a number of configuration options below
# as well, if unconfigured.
#debug = false
presumably this is still true, and at least one other thing is affected? (It's not very specific about the effects of setting debug = true) It feels like this text may want to be tweaked (e.g., to suggest the possibility of setting optimize = false to get better debuginfo)
r=me once cargo.toml.example is edited to @pnkfelix's satisfaction
and to briefly touch on the theory of debugging rustc versus the practice of such.

…eflect-pr-54811, r=Mark-Simulacrum Update `configure --help` (via configure.py) to reflect decoupling of debug+optimize This should have been part of PR rust-lang#54811 (my bad).
