2018-01-19ErLLVM: Preserve precise BEAM tailcall semanticsMagnus Lång
The BEAM compiler chooses not to perform tailcall optimisations for some calls in tail position, for example to some built-in functions. However, when the ErLLVM HiPE backend is used, LLVM may choose to perform tailcall optimisation on these calls, breaking the expected semantics. To preserve the precise semantics exhibited by BEAM, the 'notail' marker, present in LLVM since version 3.8, is added to call instructions that BEAM has not turned into tail calls, which inhibits LLVM from performing tail-call optimisation in turn.

sys_core_bsm: Rearrange arguments to enable delayed sub binary creation

* bjorn/erts/optimize-utf8/OTP-14774: Optimize matching of an 'utf8' segment in the binary syntax
2018-01-19Optimize matching of an 'utf8' segment in the binary syntaxBjörn Gustavsson
Matching out an 8-bit integer is faster than matching out an utf8-encoded code point, even if the value of the code point is less than 128. The reason is that matching out an 8-bit integer is specially optimized to avoid a function call. Do a similar optimization for matching out an utf8 segment.

The variable 'S' was used twice. If the test case failed because there were unused functions in asn1_SUITE, there would be an ugly badmatch exception instead of the intended nice error message.

2018-01-16stdlib: Garbage the shell's evaluator process more oftenHans Bolinder
A minor fix. If the Erlang shell saves no results (history(0) or results(0)), the evaluator process now garbage collects itself. This means that any huge binaries created by the evaluation are reclaimed faster than before.

2018-01-16sys_core_bsm: Rearrange arguments to enable delayed sub binary creationBjörn Gustavsson
Argument order can prevent the delayed sub binary creation. Here is an example directly from the Efficiency Guide: non_opt_eq([H|T1], <<H,T2/binary>>) -> non_opt_eq(T1, T2); non_opt_eq([_|_], <<_,_/binary>>) -> false; non_opt_eq([], <<>>) -> true. When compiling with the bin_opt_info option, there will be a suggestion to change the argument order. It turns out sys_core_bsm can itself change the order, not the order of the arguments of themselves, but the order in which the arguments are matched. Here is how it can be rewritten in pseudo Core Erlang code: non_opt_eq(Arg1, Arg2) -> case < Arg2,Arg1 > of < <<H1,T2/binary>>, [H2|T1] > when H1 =:= H2 -> non_opt_eq(T1, T2); < <<_,T2/binary>ffff>, [_|T1] > -> false; < <<>>, [] >> -> true end. When rewritten like this, the bs_start_match2 instruction will be the first instruction in the function and it will be possible to store the match context in the same register as the binary ({x,1} in this case) and to delay the creation of sub binaries. The switching of matching order also enables many other simplifications in sys_core_bsm, since there is no longer any need to pass the position of the pattern as an argument. We will update the Efficiency Guide in a separate branch before the release of OTP 21.
