External Bug:


As noted in #14422, one way in which the artifacts produced by gcc10 differ from those produced by gcc7 is that gcc10 is not removing unused static functions.
Enabling the optimisation option -ftoplevel-reorder resolves that specific problem (unused static functions are removed) but also has the side-effect of performing constant folding on many static global variables, resulting in the loss of a number of tunables which may or may not be useful; see the list below.

Obviously it also means that top-level functions, variables, and asm statements are no longer output in the same order they are declared, which may break some assumptions - further testing is necessary there.

I'm closing this as something we don't want to do. The overhead of the few remaining unused static functions is low and the utility of the tunables that would be removed is unknown but could be high. Additionally there is a problem with the way that modules like ip maintain lists of expected global symbols and validate against them - if we enabled this then we would also need a way to use different lists for primary and shadow compiler builds. There's also the question of analysing what the compiler would do if it was allowed to do top-level re-ordering since we are rather fond of being able to debug things easily.
