Check that messages outside of the heap are not corrupted
2018-04-06Check that messages outside of the heap are not corruptedBjörn Gustavsson
Waiting messages for a process may be stored in a queue outside of any heap or heap fragment belonging to the process. This is an optimization added in a recent major release to avoid garbage collection messages again and again if there is a long message queue. Until such message has been matched and accepted by the remove_message/0 instruction, the message must not be included in the root set for a garbage collection, as that would corrupt the message. The loop_rec/2 instruction explicitly turns off garbage collection of the process as long messages are being matched. However, if the compiler were to put references to a message outside of the heap in an Y register (on the stack) and there happened to be a GC when the process had been scheduled out, the message would be corrupted and the runtime system would crash sooner or later. To ensure that doesn't happen, teach beam_validator to check for references on the stack to messages outside of the heap.

2018-04-04Fix unsafe optimization of record testBjörn Gustavsson
beam_record would make an unsafe optimization for the not_used_p/4 function added to beam_utils_SUITE in this commit. The bug is in beam_utils, which would falsely report that {x,4} was unused when it in fact was used. The bug was in the function not_used/1. The purpose of not_used/1 is to return a 'not_used' result unless the actual result is 'used'. Unfortunately it was not implemented in that way. It would let a 'transparent' result slip through, which the caller in this case would convert to 'killed' (because the register was killed on all other paths). Reported-by: Richard Carlsson

2018-03-26Compile external fun expressions to literalsMichał Muskała
The expressions fun M:F/A, when all elements are literals are also treated as a literal. Since they have consistent representation and don't depend on the code currently loaded in the VM, this is safe. This can provide significant performance improvements in code using such functions extensively - a full function call to erlang:make_fun/3 is replaced by a single move instruction and no register shuffling or saving registers to stack is necessary. Additionally, compound data types that contain such external functions as elements can be treated as literals too. The commit also changes the representation of external funs to be a valid Erlang syntax and adds support for literal external funs to core Erlang.
