OTP-14461 - New 'rand' algorithm: Xoroshiro928** also for 'crypto' Implement a new 'rand' algorithm named 'exro928ss' and a new 'crypto' plugin for 'rand' named 'crypto_aes'. Both are based on Xoroshiro928** which is derived from Xoroshiro1024** modified to use 58-bit words for performance reasons in the Erlang VM. Xoroshiro1024** has got the Xoroshiro1024 generator and the StarStar scrambler from the 2018 paper "Scrambled Linear Pseudorandom Number Generators" by David Blackman and Sebastiano Vigna. This generator and scrambler combination shows no systematic weaknesses in standard statistical tests as TestU01(BigCrush) and PractRand, unlike the previously used * and + scramblers in the 'rand' module that exhibit statistical weaknesses for the lowest bits. The 'crypto' plugin uses AES-256 as scrambler and the Xoroshiro928 as generator, which gives the same very long period and jump functions as for Xoroshiro928**, but a cryptographically secure scrambler gives absolutely no detectable statistical weaknesses regardless of how the generated numbers are used. The speed of 'exro928ss' is only about 30-50% slower than the default fast 'rand' algorithm, but the state is roughly the double and it produces about 8 times the garbage per iteration. The speed of 'crypto_aes' is about half (amortized) that of the default fast 'rand' algorithm which is fast and thanks to doing encryption in batches caching the result. Hence the state is much larger.

2018-09-18crypto: Use aead functions for CHACHA20_POLY1305Hans Nilsson
This previously implemented cipher is a block cipher despite using chacha. It also uses the EVP_CIPHER_CTX api which now unifies AES_GCM and AES_CCM into one pair of encrypt and decrypt functions. By integrating the existing chacha20_poly1305 code into aead_encrypt and aead_decrypt we could remove two C-functions and simplify both the C-code and the corresponding Erlang code in the CRYPTO application.

2018-09-17stdlib: Allow lists with binaries in the Format argumentHans Bolinder
As a consequence of some refactoring (OTP-14983, option 'chars_limit'), the Format argument of io_lib:format() no longer accepts binaries in lists in Erlang/OTP 21.0. Note that if Format is not of type io:format(), control sequences in Format are ignored. This can result in unpredictable behaviour if, for example, the output of io_lib:format() is used as Format: if the output happens to be a string(), then control sequences are interpreted, otherwise not. A check that Format is of type io:format() will likely be introduced in Erlang/OTP 22.0. That will probably mean work for some users, but considering how unpredictable io_lib:format() is, we should try to fix that.

2018-09-17Remove the beam_dead and beam_split passesBjörn Gustavsson
Most of the optimizations in beam_dead have been superseded by the optimizations in beam_ssa_dead. The forward/1 pass of beam_dead has been moved to beam_jump. The beam_split pass splits blocks that contain instructions with non-zero labels. Because there are no optimizations left that optimize instructions within blocks, beam_block never needs to put such instructions into blocks in the first place. beam_split also moved 'move' instructions out block to help beam_dead. That is no longer necessary since beam_dead no longer exists.
2018-09-17Add beam_ssa_dead.erlBjörn Gustavsson
Add beam_ssa_dead to perform the main optimizations done by beam_dead: * Shortcut branches that jump to another block with a branch. If it can be seen that the second branch will always branch to a specific block, replace the target of the first branch. * Combined nested sequences of '=:=' tests and switch instructions operating on the same variable to a single switch. Diffing the compiler output, it seems that beam_ssa_dead finds many more opportunities for optimizations than beam_dead, although it does not find all opportunities that beam_dead does. In total, beam_ssa_dead is such improvement over beam_dead that there is no reason to keep beam_dead as well as beam_ssa_dead. Note that beam_ssa_dead does not attempt to optimize away redundant bs_context_binary instructions, because that instruction will be superseded by new instructions in the near future.
2018-09-17beam_ssa_codegen: Don't emit kill instructions before exit BIFsBjörn Gustavsson
Omitting `kill` instructions before BIFs that throw exceptions will reduce the code size. This optimization supersedes the same optimizations in beam_dead.

2018-09-17beam_ssa_type: Substitute variables that evaluate to a constantBjörn Gustavsson
In beam_ssa_type, do substitutions similar to what ssa_opt_misc does to get rid of variables that evaluate to constant values. That somewhat simplifies the code of beam_ssa_type, and could improve performance of the compiler since instructions and variables are eliminated, reducing the amount of work for later passes.
