2014-06-16Fix handling of latin1 characters in false ifdef branchesBjörn Gustavsson
The fallback to latin-1 encoding would not work if the invalid UTF-8 characters occurred in a skipped branch in an -ifdef/-ifndef.
2014-04-03compiler,stdlib: Fix Map literals as keys for Maps in patternsBjörn-Egil Dahlberg
2014-03-26Merge branch 'egil/maps-compiler-coverage'Björn-Egil Dahlberg
* egil/maps-compiler-coverage: compiler: Do not evaluate map expressions with bad keys compiler: Throw 'nomatch' on matching with bad binary keys compiler: Variable keys are not allowed in Maps compiler: Strengthen Maps warnings tests compiler: map_pair cannot be a type clause in v3_life compiler: Remove redudant code in v3_codegen compiler: Test deep map structure compiler: Remove redundant clause in v3_codegen compiler: Cover #{ [] => Var } in testcase
2014-03-25compiler: Do not evaluate map expressions with bad keysBjörn-Egil Dahlberg
Map keys with large (non literal) binary keys must fail.
2014-03-25compiler: Throw 'nomatch' on matching with bad binary keysBjörn-Egil Dahlberg
Even if a binary key is written as a literal the compiler may choose to make an expression. Emit a warning in those cases and saying the case will not match. This is a limitation in current implementation.
2014-03-25compiler: Strengthen Maps warnings testsBjörn-Egil Dahlberg
Increases coverage.
2014-03-25Correctly handle non-matching patterns against literal valuesAnthony Ramine
The pass sys_core_fold did not correctly handle non-matching patterns in code such as: 0 = case <<>> of <<>> -> 0; a -> 1 end. Function case_opt_lit/3 is rewritten in two passes to first remove any non-matching clause and only then potentially remove the related patterns in each clause. Reported-by: Ulf Norell

2014-03-24compiler: Cover #{ [] => Var } in testcaseBjörn-Egil Dahlberg
Coverage removed by literals.

* bjorn/compiler/utf8-warning/OTP-11791: Don't fail compilation for modules that contain invalid UTF-8 epp: Make it possible to specify a default encoding
2014-03-18Don't fail compilation for modules that contain invalid UTF-8Björn Gustavsson
The default encoding for Erlang modules is now UTF-8, and the compilation would fail if a module contained byte sequences that are not valid UTF-8 sequences. In a large project with say many hundreds of Erlang modules with names of developers such as "Björn" or "Håkan" encoded in latin-1, that could mean that many hundreds of files would need to be modified just to get started testing OTP 17. As a temporary measure to ease the transition, automatically fall back to the latin-1 encoding with a warning for any module that contains invalid byte sequences and for which no encoding has been specified. The intention is to remove this workaround in OTP 18 or 19.

2014-03-17compiler: Change Maps Core FormatBjörn-Egil Dahlberg
Ex. Instead of: M~{~<K,V>}~ The format is now: ~{~<K,V>|M}~ This also removes a shift/reduce warning. The changes in core_pp now requires compiler-5.0 to compile because of is_map/1 guard, i.e. a need for a compiler with Maps know-how.

* nox/compiler/beam_bool-mixed-boolean: Properly detect reused boolean values in beam_bool
2014-03-10Properly handle redundant boolean clauses in sys_core_foldAnthony Ramine
Boolean case expressions with redundant clauses could make the compiler crash: case X == 0 of false -> no; false -> no; true -> yes end. Reported-by: Ulf Norell

2014-03-05Do not export variables from comprehension cases in v3_coreAnthony Ramine
Code like the following snippet could make the compiler crash: f() -> [X = a || false] ++ [X = a || false]. Reported-by: Ulf Norell
2014-03-05Do not try to optimize non-boolean guardsAnthony Ramine
Expressions such as erlang:'or'(bar, true) can make beam_bool crash if it tries to optimize them, as this code is not quite really written by users, no attempt to rewrite them more efficiently should be done, for simplicity's sake. Reported-by: Ulf Norell

The Kernel instructions were not properly ordered when compiling maps with complex values mixed in assoc and exact pairs. Reported-by: Ulf Norell
2014-03-04Properly sort map pairs in v3_codegenAnthony Ramine
Literal nil values aren't tagged tuple but the bare atom nil. The function lists:sort/2 expects the passed function to return true if the first element is less than or equal to the second, not strictly less than. The original base clause is changed accordingly. Reported-by: Ulf Norell

2014-03-03Do not mark all calls to erlang:is_function/2 as safeAnthony Ramine
Calls to erlang:is_function/2 where the second is not a literal nonnegative integer can crash at runtime and thus can't be marked as safe.
2014-03-02Do not mark all calls to erlang:is_record/3 as safeAnthony Ramine
Calls to erlang:is_record/3 where the second and third arguments are not respectively a literal atom and a literal integer can't be transformed to guards and thus are not safe. Reported-by: Ulf Norell
2014-03-01Do not emit blatantly illformed Core Erlang apply expressionsAnthony Ramine
(fun f/1)() should be compiled to let X = 'f'/1 in apply X () to let the compiler properly generate code that will fail with badarity at runtime. Reported-by: Ulf Norell
