[Scummvm-devel] ATTN. Porters. Changed list of files to include

[Bertrand Augereau]

Just guessing, I'm watching the loading of the predictive dictionnary 
code and it seems pretty intensive on allocating SearchTree nodes (and 
constructing array of Strings therefore).
I can't profile it because I'm at work and I'm supposed to be doing 
something else though :)

But maybe pool-allocating the nodes would help the allocator, if it is 
an issue.
Constructing and copying the Strings might be unneccessary too, maybe 
just keeping a huge string, and slices to it (pair of size_t) could be 
beneficial.
If the T9 numbers are ignored, maybe we could just parse a preprocessed 
.dic file without those, reducing both the size and the parsing cost 
(130kB -> 80kB for trunk/dists/pred.dic)
Or binary streaming the built tree after construction, such as 
subsequent loads are fast(when the dic size and date don't change), but 
some devices storages have tricky write access...

Just my 2e6 cents,
