2019-02-05beam_ssa_type: Track the types of tuple elementsJohn Högberg
Prior to 294d66a295f6c2101fe3c2da630979ad4e736c08 there wasn't much point to keeping track of tuple element types; they were only known when we had inserted or extracted values from a tuple, and in neither case was it likely that we'd extract the same values again. It makes a lot more sense to do so now that type optimizations are applied across functions; if we return a tuple it's very likely that its elements will be extracted soon after, and knowing their types lets us eliminate more type checks.

2019-02-04Add hash function BLAKE2 to crypto:hash/hmacHans Svensson
Adds two hash functions blake2b and blake2s (64 bit hash and 32 bit hash respectively). These are modern and standard hash functions used in blockchains and encrypted communication protocols (e.g. Noise - http://www.noiseprotocol.org/). The hash functions are available in OpenSSL since version 1.1.1. Also add test cases and mention in documentation.

2019-02-01inline_SUITE: Don't start a slave nodeBjörn Gustavsson
A long time ago there was a good idea to run compiled code in a slave node. Nowadays, not so much.
2019-02-01Correct test_lib:is_cloned_mod/1Björn Gustavsson
test_lib:is_cloned_mod(inline_SUITE) would return true.
2019-02-01sys_core_fold_lists: Propagate annotations in expansion of lists functionsBjörn Gustavsson
There could be a warning with a `no_file` atom instead of filename and line number.
2019-02-01Parallelize compile_SUITE:bc_options/1Björn Gustavsson
2019-02-01Remove the optimized_guard/1 test caseBjörn Gustavsson
With the new SSA code passes, the optimized_guard/1 test case has become really bad at finding unnecessary `and` and `or` instructions.
2019-02-01Make helper functions tail-recursiveBjörn Gustavsson
Two helper functions in beam_ssa_opt and beam_ssa_dead are body-recursive for no good reason. While at it, add some clarifying comments to the functions.
2019-02-01Optimize beam_ssa:def_used/2Björn Gustavsson
beam_ssa:def_used/2 is used by beam_ssa_pre_codegen when reserving Y registers. Do the following optimizations: * Use an ordset instead of a gb_set. When the only operation performed on a set is union/2, an ordset will usually be faster, especially when the result is an ordset. * Use a cerl_set instead of a gb_set for the set of all possible predecessors. cerl_sets is usually faster than gb_sets.
2019-02-01Prefer map syntax and guard BIFs over the maps modulesBjörn Gustavsson
Avoiding calls usually reduces the size of the stack frame and reduces register shuffling.
2019-02-01beam_ssa_type: Optimize calculation of variables that are only used onceBjörn Gustavsson
2019-02-01Use gb_sets:delete/2 instead of gb_sets:delete_any/2Björn Gustavsson
Save a little time by using gb_sets:delete/2 instead of gb_sets:delete_any/2 when the key is known to be in the set.
2019-02-01Speed up beam_ssa_dead when there are many sequential blocksBjörn Gustavsson
beam_ssa_dead could be very slow if there were many blocks connected with unconditional branches (for example, if a block had contained many `call` instructions and been split by ssa_opt_split_blocks). It turns out that `comb_get_sw/3` does an unnecessary (and perhaps incorrect) recursive call to itself when the terminator for the block is an unconditional branch. Removing the recursive call does not disable any optimizations, but will be much faster if there are many blocks connected with unconditional branches. Reported-by: Michał Muskała
2019-02-01Optimize ssa_opt_sink when nothing can be sunkBjörn Gustavsson
Compilation will be much faster if there are many blocks, but no get_tuple_element instructions. Reported-by: Michał Muskała

2019-01-31Fix internal consistency failure caused by beam_exceptBjörn Gustavsson
Fix a bug where the number of live registers in a `bs_get_tail` instruction was too low. Consider this example: -export([bs_get_tail/2]). bs_get_tail(Bin, Config) -> bs_get_tail_1(Bin, 0, 0, Config). bs_get_tail_1(<<_:32, Rest/binary>>, Z1, Z2, F1) -> {Rest,Z1,Z2,F1}. `beam_validator` would emit the following diagnostics: t: function bs_get_tail_1/4+2: Internal consistency check failed - please report this bug. Instruction: {func_info,{atom,t},{atom,bs_get_tail_1},4} Error: {uninitialized_reg,{x,3}}: Here is the part of the code that generates the `function_clause` exception before the optimization: {test_heap,6,4}. {put_list,{x,3},nil,{x,2}}. {put_list,{integer,0},{x,2},{x,2}}. {put_list,{integer,0},{x,2},{x,2}}. {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},3}. %3 live registers. {test_heap,2,3}. {put_list,{x,0},{x,2},{x,1}}. {move,{atom,function_clause},{x,0}}. {line,[{location,"t.erl",8}]}. {call_ext_only,2,{extfunc,erlang,error,2}}. The `bs_get_tail` instruction expects that 3 registers will be live at this point. `beam_except` rewrites the code like this: {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},3}. %Still 3. Too low. {move,{integer,0},{x,1}}. {move,{integer,0},{x,2}}. {jump,{f,3}}. Now the number of live registers in `bs_get_tail` is too low, because the `{x,3}` register will become undefined. This commit adds code to update the number of live registers in the `bs_get_tail` instruction, producing this code: {bs_set_position,{x,1},{x,0}}. {bs_get_tail,{x,1},{x,0},4}. %Adjusted to 4. {move,{integer,0},{x,1}}. {move,{integer,0},{x,2}}. {jump,{f,3}}.

* maint: Eliminate bogus warning when using tuple calls
2019-01-30Eliminate bogus warning when using tuple callsBjörn Gustavsson
There would be a bogus warning when compiling the following function with the `tuple_calls` option: dispatch(X) -> (list_to_atom("prefix_" ++ atom_to_list(suffix))):doit(X). The warning would look like this: no_file: this expression will fail with a 'badarg' exception https://bugs.erlang.org/browse/ERL-838
