2016-01-14hipe: Fix map pretty printing of pairsBjörn-Egil Dahlberg
In commit f667931e2905797ffab63e224e56eaf07f77178a the core format changed for map pairs. Let dialyzer and hipe pretty printing of maps also adhere to those changes. An Erlang map update, M#{foo := 1, bar => 2} will now be printed as: ~{ 'foo' := 1, 'bar' => 2 | M }~
2015-12-16Fix compilation of matching with UTF binariesKostis Sagonas
The code generated by the HiPE compiler for pattern matching with UTF binaries was such that sometimes THE_NON_VALUE was stored in the roots followed by the garbage collector. This was not an issue for the vanilla native code compiler, but was problematic for the ErLLVM back-end. Fix the issue by not storing THE_NON_VALUE in the live roots. An alternative fix would be to change the code of the garbage collector. With this fix, there are no more (known) failing test cases for the ErLLVM back-end (at least on x86_64 with LLVM 3.5, which is the configuation regularly tested). Thanks to @margnus1 for the fix.

2015-10-12Fix edge case of Size = 0 in bs_put_integerKostis Sagonas
copy_offset_int_big was assuming (Offset + Size - 1) (Tmp9 in the first BB) would not underflow. It was also unconditionally reading and writing the binary even when Size was zero, unlike copy_int_little, which is the only other case of bs_put_integer that does not have a short-circuit on Size = 0. This was causing segfaults when constructing binaries starting with a zero-length integer field, because a logical right shift was used to compute an offset in bytes (which became 0x1fffffffffffffff) to read in the binary. Tests, taken from the emulator bs_construct_SUITE, were also added. The complete credit for the report and the fix goes to Magnus Lång.
2015-10-09Update and cleanup HiPE recordsKostis Sagonas
The bulk of the changes concerns cleanups and code refactorings concerning record constructions that assigned 'undefined' to record fields whose type did not contain this value. See commit 8ce35b2. While at it, some new type definitions were introduced and type names were used instead of record type notation. Minor code cleaups were also done.
2015-10-08Take out automatic insertion of 'undefined' from typed record fieldsKostis Sagonas
Background ----------- In record fields with a type declaration but without an initializer, the Erlang parser inserted automatically the singleton type 'undefined' to the list of declared types, if that value was not present there. I.e. the record declaration: -record(rec, {f1 :: float(), f2 = 42 :: integer(), f3 :: some_mod:some_typ()}). was translated by the parser to: -record(rec, {f1 :: float() | 'undefined', f2 = 42 :: integer(), f3 :: some_mod:some_typ() | 'undefined'}). The rationale for this was that creation of a "dummy" #rec{} record should not result in a warning from dialyzer that e.g. the implicit initialization of the #rec.f1 field violates its type declaration. Problems --------- This seemingly innocent action has some unforeseen consequences. For starters, there is no way for programmers to declare that e.g. only floats make sense for the f1 field of #rec{} records when there is no `obvious' default initializer for this field. (This also affects tools like PropEr that use these declarations produced by the Erlang parser to generate random instances of records for testing purposes.) It also means that dialyzer does not warn if e.g. an is_atom/1 test or something more exotic like an atom_to_list/1 call is performed on the value of the f1 field. Similarly, there is no way to extend dialyzer to warn if it finds record constructions where f1 is not initialized to some float. Last but not least, it is semantically problematic when the type of the field is an opaque type: creating a union of an opaque and a structured type is very problematic for analysis because it fundamentally breaks the opacity of the term at that point. Change ------- To solve these problems the parser will not automatically insert the 'undefined' value anymore; instead the user has the option to choose the places where this value makes sense (for the field) and where it does not and insert the | 'undefined' there manually. Consequences of this change ---------------------------- This change means that dialyzer will issue a warning for all places where records with uninitialized fields are created and those fields have a declared type that is incompatible with 'undefined' (e.g. float()). This warning can be suppressed easily by adding | 'undefined' to the type of this field. This also adds documentation that the user really intends to create records where this field is uninitialized.
2015-10-02Fix matching with huge binariesKostis Sagonas
In certain cases of matching with very big binaries, the HiPE compiler generated code that would fail the match, even in cases that the matching was successful. The problem was more quite noticeable on 32-bit platforms where certain integer quantities would be represented as bignums. Brief summary of changes: * gen_rtl({bs_skip_bits, ...}, ...) could not handle too large constants. Previously the constants were truncated to word size. * hipe_rtl_binary_match:make_size/3 erroneously assumed that the output of first_part/3 would not overflow when multiplied by 8, which is no longer true. To maintain full performance, the overflow test is only performed when BitsVar was a bignum. Thus, the fast path is identical to before. * hipe_rtl_binary_match:set_high/2 was assuming that only bits below bit 27 were ever set in arguments to bs_skip_bits, which is not only false when the arguments are bignums, but also on 64-bit platforms. The commit includes a test taken from the bs_match_bin_SUITE. Most of the credit for finding these HiPE compiler errors and for creating appropriate fixes for them should go to Magnus Lång.
