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_type: Simplify is_singleton_type/1Björn Gustavsson
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.
2019-01-17Make the beam_validator smarter (again)Björn Gustavsson
Needed because of the optimizations in 48f20bd589fa69. https://bugs.erlang.org/browse/ERL-832
2019-01-17Write some more comments in the engine loopRaimo Niskanen
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.

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.
2019-01-17ssl: Correct 3des_ede_cbc checkIngela Anderton Andin
Could cause ssl to claim to support 3des_ede_cbc when cryptolib does not
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).
