- <p><c>record_info/2</c> is a pseudo-function that
- requires literal arguments known at compile time.
- Therefore, the following usage is illegal: <c>fun
- record/info/2</c>. The compiler would crash when during
- compilation of that kind of code. Corrected to issue a
- compilation error.</p>

- <p>
- The compiler has been rewritten to internally use an
- intermediate representation based on Static Single
- Assignment (SSA). The new intermediate representation
- makes more optimizations possible.</p>
- <p>
- Most noticeable is that the binary matching optimizations
- are now applicable in many more circumstances than
- before.</p>
- <p>
- Another noticeable change is that type optimizations are
- now applied across local function calls, and will remove
- a lot more redundant type tests than before.</p>

- <p>Funs are no longer created when they are only used
- locally, greatly improving the performance of named funs
- and "fun-wrapped" macros.</p>

- Own Id: OTP-15273 Aux Id: ERL-639 </p>
- </item>
- <item>
- <p>All compiler options that can be given in the source
- file can now also be given in the option list or from the
- command line for <c>erlc</c>.</p>
- <p>Specifically, the option
- <c>{nowarn_deprecated_function,MFAs}</c> was only
- recognized when given in the file with the attribute
- <c>-compile()</c>. The option
- <c>{nowarn_unused_function,FAs}</c> was incorrectly
- documented to only work in a file, but it also worked
- when given in the option list.</p>

- <item>
- <p>Internal documentation has now been added to the
- <em>Erts</em> and <em>Compiler</em> applications.</p>
- <p>The internal documents for <em>Erts</em> describe
- miscellaneous interesting implementation details. Those
- details can change at any time.</p>
- <p>The internal documentation for <em>Compiler</em>
- documents the API for the Core Erlang modules. While we
- will not change those APIs without good reason, we don't
- give the same guarantees about backward compatibility as
- for the rest of the APIs in OTP.</p>

- Own Id: OTP-15715</p>
- </item>
- <item>
- <p> There are new compiler options <c>nowarn_removed</c>
- and <c>{nowarn_removed,Items}</c> to suppress warnings
- for functions and modules that have been removed from
- OTP.</p>
