Some of the noteworthy changes compared to Tiger 2015:

Use of even more C++ 2011 features

The compiler introduces the following C++ 2011 features:

− (standard) smart pointers (std::unique_ptr, std::shared_ptr);
− general-purpose initializer lists;
− lambda expressions;
− explicit overrides;
− template aliases;
− new function declarator syntax;
− delegating constructors;
− non-static data member initializers;
− inherited constructors.

The whole set of C++ features used in the Tiger compiler is supported by both GCC 4.8 and Clang 3.3.

C++ scanner

We introduce a C++ scanner this year, still generated by Flex, but implemented as classes. The management of the scanner’s inputs has been improved and responsibilities shared between the scanner and the driver (parse::TigerParser).

More Git Usage

Starting this year, we deliver code with gaps exclusively through the tc-base public Git repository. We no longer provide tarballs nor patches as a means to update students’ code bases.

Changes in the language regarding object-oriented constructs

The nil keyword has been made compatible with objects.

Style

Many stylistics changes have been performed, mainly to match the EPITA Coding Style.
