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
