Fixes a crash during code generation of the following code: call_atom() -> fun({send = Send}) -> Send() end.
2018-10-05compiler: Forward +source flag to epp and fix bug in +deterministicJohn Högberg
The source file path as given to `erlc` was included in an implicit file attribute inserted by epp, even when the +source flag was set to something else which was a bit surprising. It was also included when +deterministic was specified, breaking the flag's promise. This commit forwards the +source flag to epp so it inserts the right information, and if +deterministic is given it will be shaved to just the base name of the file, guaranteeing the same result regardless of how the input is reached.

Note that this does *not* affect -include()'d files or the -file() directive.

2018-10-03Optimize named funs and fun-wrapped macrosJohn Högberg
If a fun is defined locally and only used for calls, it can be replaced with direct calls to the relevant function. This greatly speeds up "named functions" (which rely on make_fun to recreate themselves) and macros that wrap their body in a fun.

* bjorn/compiler/fix-binary-matching/ERL-689/OTP-15335: Fix rare bug in binary matching (again)
2018-10-01Introduce the no_spawn_compiler_process optionJosé Valim
By default, all code is compiled in a separate process which is terminated at the end of compilation. However, some tools, like Dialyzer or compilers for other BEAM languages, may already manage their own worker processes and spawning an extra process may slow the compilation down. In such scenarios, you can pass this option to stop the compiler from spawning an additional process. This generalizes commit 657760e18087b0cdbaecc5e96e46f6f66bc9497a.

2018-09-28Fix code generation of binary instructions with the r21 optionBjörn Gustavsson
OTP 22 extends the binary instructions to support a Y register destination. When giving an option to compile for an earlier release, make sure that binary instructions don't use a Y register destination, by rewriting the binary instructions to use an X register destination and adding a `move` instruction to move the value to the Y register.

2018-09-28beam_ssa_opt: Eliminate redundant match alignment testsJohn Högberg
The beam_ssa_bsm pass welds chained matches together, but the match expressions themselves are unchanged and if there's a tail alignment check it will be done each time. This subpass figures out the checks we've already done and deletes the redundant ones.
2018-09-28Rewrite BSM optimizations in the new SSA-based intermediate formatJohn Högberg
This commit improves the bit-syntax match optimization pass, leveraging the new SSA intermediate format to perform much more aggressive optimizations. Some highlights: * Watch contexts can be reused even after being passed to a function or being used in a try block. * Sub-binaries are no longer eagerly extracted, making it far easier to keep "happy paths" free from binary creation. * Trivial wrapper functions no longer disable context reuse.

2018-09-28Fix rare bug in binary matching (again)Björn Gustavsson
2e40d8d1c51a attempted fix a bug in binary matching, but it only fixed the bug for the minimized test case. This commit removes the previous fix and fixes the bug in a more effective way. See the comments in the new code in `sys_core_bsm` for an explanation. This commit restores the optimizations in string.erl and dets_v9.erl that the previous fix disabled. I have not found any code where this commit will disable optimizations when they are actually safe. There are some changes to the code in ssl_cipher.erl in that some bs_start_match2 instruction did not reuse the binary register for the match context, but the delayed sub binary optimizations was never applied to the code in the first place. https://bugs.erlang.org/browse/ERL-689
