2018-06-25Fix unsafe optimization when running beam_block the second timeBjörn Gustavsson
The compiler would crash when compiling code such as: serialize(#{tag := value, id := Id, domain := Domain}) -> [case Id of nil -> error(id({required, id})); _ -> <<10, 1:16/signed, Id:16/signed>> end, case Domain of nil -> error(id({required, domain})); _ -> <<8, 2:16/signed, Domain:32/signed>> end]. The crash would look like this: Function: serialize/1 t.erl: internal error in block2; crash reason: {badmatch,false} in function beam_utils:live_opt/4 (beam_utils.erl, line 861) in call from beam_utils:live_opt/1 (beam_utils.erl, line 285) in call from beam_block:function/2 (beam_block.erl, line 47) in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33) in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33) in call from beam_block:module/2 (beam_block.erl, line 33) in call from compile:block2/2 (compile.erl, line 1358) in call from compile:'-internal_comp/5-anonymous-1-'/3 (compile.erl, line 349) The reason for the crash is an assertion failure caused by a previous unsafe optimization. Here is the code before the unsafe optimization: . . . {bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}. {bs_put_string,3,{string,[8,0,2]}}. {bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}. {move,{x,1},{x,0}}. {test_heap,4,1}. . . . beam_block:move_allocate/1 moved up the test_heap/2 instruction past the move/2 instruction, adjusting the number of live registers at the same time: . . . {bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}. %% Only x1 is live now. {bs_put_string,3,{string,[8,0,2]}}. {bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}. {test_heap,4,2}. %Unsafe. x0 is dead. {move,{x,1},{x,0}}. . . . This optimization is unsafe because the bs_init2 instruction killed x0. The bug is in beam_utils:anno_defs/1, which adds annotations indicating the registers that are defined at the beginning of each block. The annotation before the move/2 instruction incorrectly indicated that x0 was live. https://bugs.erlang.org/browse/ERL-650 https://github.com/elixir-lang/elixir/issues/7782
2018-06-25stdlib: Add a few uses of erl_annoHans Bolinder
With DEBUG=true in erl_anno, erl_parse, and erl_pp a few (harmless) non-opaque accesses of annotations were found.

2018-06-14Included config files relative to sys.config dircrownedgrouse
Change the way included config files are searched in sys.config. Search first relative to sys.config directory, then relative to current working directory, for backward compatibility. This permit same result when using a sys.config file in a release or starting manually a node with -config. Credit to Siri Hansen for test case.

2018-06-14crypto: Remove EVP_PKEY from dh_compute_key_nifHans Nilsson
According to valgrind, there is a memory leak. When fixing that there is a core-dump instead. Since generate_key is the part that is important for the quality of the key we keep the old compute_key part to avoid memory leakage.
