2018-11-15beam_ssa_dead: Speed up optimization of switch instructionsBjörn Gustavsson
`beam_ssa_dead` can waste a lot of time trying to optimize an unoptimizable `switch` instruction. By being a little bit smarter when optimizing `switch` instructions, the runtime for the beam_ssa_dead pass was reduced approximately by half on my computer for this module: https://github.com/aggelgian/cuter/blob/master/src/cuter_binlib.erl Noticed-by: Kostis Sagonas
2018-11-15beam_ssa_pre_codegen: Eliminate a bottleneck in linear scanBjörn Gustavsson
The linear scan algorithm keeps unhandled intervals in two separate lists: one for intervals with reserved registers and one for intervals without reserved registers. When collecting the available free registers all unhandled intervals with reserved registers must be checked for overlap. Unhandled intervals that had a preferred register were put into the list of intervals with reserved registers, leading to a lot of unecessary overlap checking if there were many intervals with preferred registers. Changing the partition code to put intervals with preferred registers into the general list of unhandled intervals will reduce the compilation time if there are many preferred registers. On my computer, this change reduced the time of the linear scan pass from about 20 seconds down to about 0.5 seconds for this module: https://github.com/aggelgian/cuter/blob/master/src/cuter_binlib.erl Noticed-by: Kostis Sagonas
2018-11-15beam_ssa_type: Speed up type analysis for huge functionsBjörn Gustavsson
The type analysis pass (`beam_ssa_type`) keeps the type information for all variables that are in scope. For huge functions, the `join_types/2` function could get really slow when joining two maps with thousands of variables in each. Use a conservative approach to discard type information for variables only used once by a `br` or `switch` in the same block as the variable is defined in. This approach reduces the runtime for the `beam_ssa_type` pass from a few minutes down to few seconds for this module: https://github.com/aggelgian/cuter/blob/master/src/cuter_binlib.erl Rejected approach: Calculate liveness information for all variables and discard type information for any variable that would not be used again. That turned out to not work because some optimizations would invalidate the liveness (in particular, substitutions could lengthen the lifetime for a variable). Trying to update the liveness information when doing the optimizations would be tricky. Noticed-by: Kostis Sagonas

A bug for SSH_MSG_EXT_INFO was fixed both for client and server. Before that fix, wrong option was read for the information sent to the peer. This commit adapts the option checking so that the correct option now used is available not only for servers but also for clients.
