Deliveries for ing1 student:

Some of the noteworthy changes compared to Tiger 2026:

TC-1 & TC-2: TC-1 & TC-2 stages have been merged into TC-1/2, Scanner, Parser & Building the Abstract Syntax Tree. This aims to merge the lexer/parser & AST stages to offer students a longer common period.
HAVM & OVM: HAVM is now in a transition & replacement phase. OVM is a brand-new tool to evaluate Intermediate representation TREE. It is implemented in OCaml and finally solves HAVM’s main problems.
LLVM: LLVM has been updated to LLVM 18 and the documentation updated accordingly (deprecated functions, replacements, etc.).
assignments: assignments, which constitutes the main documentation of the Tiger compiler, has been entirely revisited to offer more comprehensive and up-to-date documentation (information, dead links, source code, etc.).
Custom Extensions: Students may now choose to implement custom extensions of their choice during TC-EXTS, Improving Your Compiler with Fun Extensions. Subjects must be given approval beforehand and will be graded in the form of a defense rather than usual automated tests.
