2018-02-15badarg on iolist_to_binary(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were returned as-is instead of badarging.
2018-02-15Handle unaligned binaries in enif_inspect_iovecJohn Högberg
2018-02-15Handle unaligned binaries in erlang:iolist_to_iovec/1John Högberg
A binary is a binary as long as its size in bits is evenly divisible by 8, regardless of whether it has a bit offset or not.
2018-02-15badarg on iolist_to_iovec(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were silently truncated to [] instead of badarging.
2018-02-15Test badarg when an improper list tail contains a bitstringJohn Högberg
This has always worked but we lacked test coverage for it.

2018-02-13Use smaller inputs in iovec testsJohn Högberg
Huge inputs weren't particularly useful and took forever to run, so this commit winds it down to a more sane level that still causes lots of yielding.

2018-01-29erts: Refactor hipe x86_64 trampolinesSverker Eriksson
2018-01-29make HiPE work on x86_64 when PIE is enabledbhuztez
Currently HiPE amd64 assumes the runtime system code is loaded into the low 2G of the address space. However, this is not the case when PIE is enabled, it is loaded into a random location. So trampolines are required to call BIFs, and also we have first to load the address of sse2_fnegate_mask to a regisiter before xorpd in fchs.
2018-01-26Eliminate get_list/3 internally in the compilerBjörn Gustavsson
Instructions that produce more than one result complicate optimizations. get_list/3 is one of two instructions that produce multiple results (get_map_elements/3 is the other). Introduce the get_hd/2 and get_tl/2 instructions that return the head and tail of a cons cell, respectively, and use it internally in all optimization passes. For efficiency, we still want to use get_list/3 if both head and tail are used, so we will translate matching pairs of get_hd and get_tl back to get_list instructions.

2018-01-24Fix more missing ERTS_WRITE_UNLIKELY section on declarationSebastien Merle
2018-01-24Make sure ERTS_WRITE_UNLIKELY section is also set on declarationPeer Stritzinger
Otherwise on targets which have small data area with short addressing like on PowerPC ther will be linking errors due to the mismatch of declaration/usage and definition.

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.

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.
