Back-End
In a compiler, the term Back End (BE) is sometime
confused with code generator for the overlapped functionality of
generating assembly code. The work in back end is done in multiple steps:
1. Compiler analysis - This is the process to gather program information from the
intermediate representation of the input source files.
2. Optimization - the intermediate language representation is transformed into
functionally equivalent but faster (or smaller) forms.
3. Code generation - the transformed intermediate language is translated into the
output language, usually the native machine language of the system. This
involves resource and storage decisions, such as deciding which variables to
fit into registers and memory and the selection and scheduling of appropriate
machine instructions along with their associated addressing modes.
In general, the BE of a Language Processor (LP) is the subset of modules that,
after the analysis phase, perform transformation that depend on the
Intermediate Representation (IR) and not directly on the source tests.
