2019-01-17beam_ssa_type: Eliminate redundant 'succeeded' instructionsBjörn Gustavsson
The beam_ssa_type pass would leave redundant 'succeeded' instructions, and depend on the live optimization pass to remove them. Update beam_ssa_type to remove redundant 'succeeded' instructions. This will not improve the generated code, but will improve compilation times since it eliminates instructions and variables.

Eliminate the beam_bs compiler pass
2019-01-16Move optimizations of bs_put* instruction to beam_ssa_optBjörn Gustavsson
Do the optimizations of bs_put* instructions in beam_ssa_opt and remove the beam_bs pass. This can lead to a slight improvement of compilation times.
2019-01-16Refactor string operandsBjörn Gustavsson
There are two instructions that take string operands: {bs_put_string,Fail,NumberOfBytes,{string,String}} {bs_match_string,Fail,Register,NumberOfBits,{string,String}} In the canonical BEAM code that is passed to beam_asm, string String is currently represented as a list. (The string in bs_match_string is a bitstring before the beam_z compiler pass.) That is wasteful, because there will be unnecessary conversions between lists and binaries. Change the representation of String to be a binary. Furthermore, bs_put_string is an optimization of a bs_put_binary instruction with a literal binary operand. Currently, the bs_put_string instruction is introduced in beam_bs. Delay the introduction of bs_put_string to the beam_z pass. That will simplify optimizations and allow us to do the optimization currently done in beam_bs in a SSA pass in a future commit.
2019-01-16Move coalescing of bs_skip to beam_ssa_optBjörn Gustavsson
The optimization can be applied in a few more places if done before ssa_opt_bsm_shortcut (for example, in unicode:cbv/2).
