2017-05-05Clear p->fvalue when handling a try/catchBjörn Gustavsson
p->fvalue will be set by BIFs that generate exceptions (such as throw/1), and it will not be cleared before another exception is generated. Potentially, p->fvalue may contain a huge term (e.g. after throw(HugeTerm)) which will be kept in the heap. We can shorten the lifetime of f->value by clearing it in the instructions that handle catches: catch_end and try_end. That is safe because BEAM code will never access p->fvalue. If BEAM code needs to rethrow an exception it will use a reference to the value passed in an X register. The reason that p->fvalue must not be cleared already in handle_error() is that native code trap handlers will use it. (See the comment before handle_error() and the comment at the end of handle_error() in beam_emu.c for some more information about exception handling.)

2017-04-27Rename macro and add clarifying commentRichard Carlsson
The macro previously named 'LOG2' is in fact computing the LSB (not the MSB) of its input, and can only be used to compute log2(n) when n is is a power of 2, that is, when its LSB is also its MSB.

2017-04-25Store abstract code in the Dbgi chunkJosé Valim
The new Dbgi chunk returns data in the following format: {debug_info_v1, Backend, Data} This allows compilers to store the debug info in different formats. In order to retrieve a particular format, for instance, Erlang Abstract Format, one may invoke: Backend:debug_info(erlang_v1, Module, Data, Opts) Besides introducing the chunk above, this commit also: * Changes beam_lib:chunk(Beam, [:abstract_code]) to read from the new Dbgi chunk while keeping backwards compatibility with old .beams * Adds the {debug_info, {Backend, Data}} option to compile:file/2 and friends that are stored in the Dbgi chunk. This allows the debug info encryption mechanism to work across compilers * Improves dialyzer to work directly on Core Erlang, allowing languages that do not have the Erlang Abstract Format to be dialyzer as long as they emit the new chunk and their backend implementation is available Backwards compatibility is kept across the board except for those calling beam_lib:chunk(Beam, ["Abst"]), as the old chunk is no longer available. Note however the "Abst" chunk has always been optional. Future OTP versions may remove parsing the "Abst" chunk altogether from beam_lib once Erlang 19 and earlier is no longer supported. The current Dialyzer implementation still supports earlier .beam files and such may also be removed in future versions.
