* ingela/ssl/hs-env-start: ssl: Create hs_env ssl: Remove unnecessary iolist_to_binary
2019-01-22ssl: Create hs_envIngela Anderton Andin
We want to decrease the size of the outer state tuple, and gain ease of understanding by better grouping. This is the first step of creating a hs_env (handshake environment) part of the state. This change will be performed gradually to reduce merge conflicts complexity and risk of introducing errors.

2019-01-21correct: Work around a compiler mis-optimizationRaimo Niskanen
This was not a compiler optimization that misfired, rather that the code neede separate case clauses for when the timer was running and not, so to not call erlang:cancel_timer/1 nor maps:remove/2 in the case clause where only a map update was needed before recursion. See the comment in loop_timouts_cancel/13

2019-01-18beam_ssa_opt: Run ssa_opt_tuple_size earlyBjörn Gustavsson
Running ssa_opt_tuple_size early will give more opportunities for optimizations.
2019-01-18beam_ssa_codegen: Remove forgotten and unreachable clauseBjörn Gustavsson
fd682dd3b1dc corrected label generation for 'or', but forgot to remove the old incorrect clause (that can no longer be reached).
2019-01-18beam_ssa_opt: Run the type optimization pass twiceBjörn Gustavsson
The code will be significantly improved by running the type optimization pass twice. The ssa_opt_misc pass can be eliminated because everything it does is also done by the type optimization pass.

2019-01-17Work around a compiler mis-optimizationRaimo Niskanen
The common subexpression optimization accidentally caused unnecessary spilling of live registers. A rather ugly workaround can be found in loop_timeouts_cancel.

2019-01-17sys_core_inline: Kill *all* fun annotations when inliningBjörn Gustavsson
sys_core_inline didn't kill fun annotations in variables, which could lead to duplicated wrapper functions for funs. That was basically harmless because the duplicated functions were eventually discarded.
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.

There seems to be an incorrect merge conflict resolution in abde22933f5a that merged maint to master. Dumping of references (and possibly other terms) were broken.

2019-01-17Move out helper functions to engine loopRaimo Niskanen
This strategy improves speed benchmarks and reduces the amount of garbage that is produced. More: * Handle transition options as loop function arguments instead of in a record. * Shorten the state_enter loop and make it more efficient by making it more part of the loop and less a loop restart. * Simplify the internal timeout action handling somewhat.

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).
