Register allocation (mapping variables to processor registers or memory) and instruction
scheduling (reordering instructions to increase instruction-level parallelism) are essential …

Modern microprocessors are equipped with single instruction multiple data (SIMD) or vector
instruction sets which allow compilers to exploit superword level parallelism (SLP), a type of …

This article introduces a combinatorial optimization approach to register allocation and
instruction scheduling, two central compiler problems. Combinatorial optimization has the …

We aim to automate decades of research and experience in register allocation, leveraging
machine learning. We tackle this problem by embedding a multi-agent reinforcement …

This paper introduces a constraint model and solving techniques for code generation in a
compiler back-end. It contributes a new model for global register allocation that combines …

A code sequence made up multiple instructions and specifying an offset from a base
address is identified in an object file. The offset from the base address corresponds to an …

(57) ABSTRACT A code sequence made up multiple instructions and specify ing an offset
from a base address is identified in an object file. The offset from the base address …

Object code is generated from an internal representation that includes a plurality of source
operands. The generating includes performing for each source operand in the internal …

Handwritten assembly is a widely used tool in the development of high-performance
cryptography: By providing full control over instruction selection, instruction scheduling, and …

Code generation in a compiler is commonly divided into several phases: instruction
selection, scheduling, register allocation, spill code generation, and, in the case of clustered …
