2019-02-22erts: Implement fragmentation of distrubution messagesLukas Larsson
2019-02-21erts: Move reason in dist messages to payloadLukas Larsson
The dist messages EXIT, EXIT2 and MONITOR_DOWN have been updated with new versions that send the reason term as part of the payload of the message instead of as part of the control message. This allows the decode of the reason to be done by the receiving process instead of the dist entry which in turn makes it possible for multiple decodes to be done in parallel. This change is done in order to make it easier to fragment the potentially large payload of EXIT, EXIT2 and MONITOR_DOWN into multiple distribution messages. OTP-15611
2019-02-21erts: Remove a copy of distribution data payloadLukas Larsson
Before this change the inet driver was in list mode and thus the data from it had to be copied when received by the dist entry. This change puts the tcp port in binary mode and makes the any refc binary created by it be used all the way to the process where it is decoded. Thus eliminating one copy of the entire message payload.
2019-02-21erts: Yield later during process exit and allow free procs to runLukas Larsson

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.

2019-02-01Use 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}}.

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).

2019-01-29Add lib/compiler/scripts/smokeBjörn Gustavsson
Add `lib/compiler/scripts/smoke` for smoke testing the compiler (that is, test that the compiler does not crash during compilation). `smoke` first installs Elixir and mix. It then uses `mix` to download a number of `hex` packages and compile them. We don't intend to use `smoke` in our daily builds or Travis, but to run it manually during compiler development.
