Prilagoditev LLVM-ja za sistem SIC/XE

ERZAR, JAKOB (author), Slivnik, Boštjan (mentor)

Ogrodje LLVM omogoča lažji razvoj prevajalnikov, saj ga v prevajalniku lahko uporabimo za generiranje strojne kode več različnih arhitektur. V tem diplomskem delu vanj dodamo podporo za generiranje strojne kode arhitekture SIC/XE, ki je namenjena poučevanju sistemske programske opreme. S tem omogočimo prevajanje v strojno kodo sistema SIC/XE iz vseh programskih jezikov, ki se lahko prevedejo v LLVM-jevo vmesno kodo. Podporo za arhitekturo SIC/XE integriramo tudi v prevajalnik Clang, ki je namenjen predvsem prevajanju jezikov C in C++. Delovanje pokažemo s prevajanjem treh programov v C-ju in primerjamo število ukazov glede na stopnjo optimizacije.

Abstract

The LLVM compiler framework can be used as a compiler backend that supports generating machine code for multiple computer architectures. In this thesis we implemented an LLVM backend for the SIC/XE architecture, which is used for teaching system software. This enables generation of SIC/XE machine code from every language that can be compiled to LLVM’s intermediate representation. We also added SIC/XE support to the Clang compiler, which is used for compiling C-family programming languages. We demonstrated our work with compilation of three different C programs and compared the amount of instructions with different optimization levels.
