| 2016-01-12 | Fix crash when attempting to update a fun as if it were a map | Björn Gustavsson | |
| The following example would cause an internal consistency failure in the compiler: f() -> ok. update() -> (fun f/0)#{u => 42}. The reason is that internally, v3_core will (incorrectly) rewrite update/0 to code similar to this: update() -> if is_map(fun f/0) -> maps:update(u, 42, fun f/0) end. Since funs are not allowed to be created in guards, incorrect and unsafe code would be generated. It is easy to fix the bug. There already is a is_valid_map_src/1 function in v3_core that tests whether the argument for the map update operation can possibly be a valid map. A fun is represented as a variable with a special name in Core Erlang, so it would not be recognized as unsafe. All we'll need to do to fix the bug is to look closer at variables to ensure they don't represent funs. That will ensure that the code is rewritten in the correct way: update() -> error({badmap,fun f/0}) end. Reported-by: Thomas Arts | |||

| * maint: Eliminate crash in v3_codegen | |||
| 2016-01-11 | Eliminate crash in v3_codegen | Björn Gustavsson | |
| The following code would crash v3_codegen: order(From) -> catch if From#{[] => sufficient} -> saint end. Before explaining the crash, first some background on the stack frame and the Y registers. Certain instructions, most notably the 'call' instructions, clobber all X registers. Before any such instruction, all X registers that have values that will be used after the call must be saved to Y registers (i.e. to the stack frame). adjust_stack/4 will be called when X registers must be saved. There is also another situation when X registers must be saved, namely within a 'catch' if we are about to execute any instruction that may cause an exception. Examples of such instructions are some guard BIFs (such as length/1) and construction of binaries or maps. Within a 'catch', X registers must be be saved because if an exception is thrown and catched all X registers will be destroyed. The same adjust_stack/4 function will be called for those instructions, but only if they occur within a 'catch'. There is actually one more complication. If there is code in a guard within a catch, the X registers should not be saved, because the code in a guard never clobbers any X registers that were alive before the guard code was entered. v3_codegen is written with the implicit assumption that code in guards never cause anything to be saved to Y registers. The code for building maps and binaries would incorrectly save X registers within a guard inside a 'catch'. For construction of binaries, that would mean that a useless but harmelss 'move' instruction was generated. But for construction of maps, the saving of the Y register would not be harmless. There would be a crash when attempting to merge #sr{} records. #sr{} records keeps track of the contents of X and Y registers. When two separate code paths are joined (e.g. at the end of 'case' statement), the register descriptors must be reconciled. Basically, the register descriptors for both paths must be identical. The #sr{} record for one path must not claim that {y,0} contains a certain value, while another path claims that {y,0} is dead. Thus, the crash occurs in sr_merge/2 when failing to reconcile the Y registers. To fix this bug this bug we will introduce a new function called maybe_adjust_stack/5. It will save X registers on the stack only if the code is inside a catch but not inside a guard. We will change all existing code to use this new function when appropriate.

| 2016-01-07 | beam_bool: Fix unsafe optimization | Björn Gustavsson | |
| beam_bool would make the following code unsafe (which would be reported by beam_validator): scotland(Echo) -> found(case Echo of Echo when true; Echo, Echo, Echo -> Echo; echo -> [] end, Echo = placed). found(_, _) -> million. Basically, beam_bool would see that the 'case' would always return the value of Echo. Thus: scotland(Echo) -> found(Echo, Echo = placed). The only problem is that beam_bool would also remove a 'move' instruction that would save Echo to the stack. Here is the assembly code for part of the function: {allocate_zero,1,1}. {move,{x,0},{y,0}}. %% Save Echo on stack. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,1}}. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,2}}. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,3}}. {bif,'and',{f,7},[{x,2},{x,3}],{x,2}}. {bif,'and',{f,7},[{x,1},{x,2}],{x,1}}. {jump,{f,8}}. {label,7}. {move,{atom,false},{x,1}}. {label,8}. {bif,'or',{f,6},[{atom,true},{x,1}],{x,1}}. {test,is_eq_exact,{f,6},[{x,1},{atom,true}]}. %% Jump never taken. {jump,{f,5}}. {label,6}. {test,is_eq_exact,{f,9},[{x,0},{atom,echo}]}. {move,nil,{x,0}}. {jump,{f,5}}. {label,9}. {test_heap,3,0}. {put_tuple,2,{x,0}}. {put,{atom,case_clause}}. {put,{y,0}}. {line,[{location,"t.erl",5}]}. {call_ext,1,{extfunc,erlang,error,1}}. {jump,{f,5}}. {label,5}. {test,is_eq_exact,{f,12},[{atom,placed},{y,0}]}. beam_bool would see that the is_eq_exact test at label 8 would always succeed. It could therefore remove most of the code before the jump to label 5. Unfortunately it also removed the essential move of Echo to the stack: {allocate_zero,1,1}. %% Instruction incorrectly removed: {move,{x,0},{y,0}}. {jump,{f,5}}. {label,5}. {test,is_eq_exact,{f,12},[{atom,placed},{y,0}]}. The root cause of the problem is that the 'move' instruction is included in the block of 'bif' instructions before label 8. Normally the 'move' instruction would not have been discarded, but because the left operand to the 'or' BIF is 'true', the entire block with 'bif' instructions are dropped. As far as I can see, there is no gain by including 'move' instructions in the first place. There is no way that better code will be produced. In fact, the entire optimization can be given up if 'move' instructions are found in the block. Thus we can fix this bug by never including any 'move' instructions in the block of 'bif' instructions. We can also remove all the code that deals with 'move' instructions within blocks. Reported-by: Thomas Arts | |||
