Re: [PATCH]: Structure aliasing, part 1

Two options. We either disable SFTs for Ada or tweak --param global-var-threshold to be much lower for Ada. In the meantime we need to figure out better heuristics for both .global_var and SFT generation.

There's a FIXME note in maybe_create_global_var about creating several .GVs, one per type or alias set. Perhaps that's another idea to try. The thing is that once we created .GV it's game over for the aliaser. Suddenly everything is related to everything.

The patch is fine with those Ada tweaks to the GV threshold.


Diego.
