If the number of warnings is huge the '--'/2 operator is slow.
2018-01-22Don't build a stacktrace if it's only passed to erlang:raise/3Björn Gustavsson
Consider the following function: function({function,Name,Arity,CLabel,Is0}, Lc0) -> try %% Optimize the code for the function. catch Class:Error:Stack -> io:format("Function: ~w/~w\n", [Name,Arity]), erlang:raise(Class, Error, Stack) end. The stacktrace is retrieved, but it is only used in the call to erlang:raise/3. There is no need to build a stacktrace in this function. We can avoid the building if we introduce an instruction called raw_raise/3 that works exactly like the erlang:raise/3 BIF except that its third argument must be a raw stacktrace.

* ingela/ssl/remove-3des-from-default/OTP-14768: ssl: Remove 3DES cipher suites from default
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.

* 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.

2018-01-17Fix slow hipe executionSverker Eriksson
particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

2018-01-17asn1_SUITE: Fix failure in xref_export_all/1Björn Gustavsson
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.
