CST302-COMPILER DESIGN
In the early days of computation instructions to a computer were given using
perforated paper tapes and punch cards. In the 50s computer scientists came
up with various language translators the first one was the assembler debuted
in the late 1948. The interpreter and the compilers came into picture in the
1950s. In this session we will learn about the emergence of compilers
followed by the different phases of it. C codes are almost like the English
language but syntactically c code is almost like English. The language
translator has four different phases the first one is the pre-processor this pre-
processor resolves all the directives as for this particular code reading the
hash include pre-processor directive it will append the standard input output
header file to the high-level language code. The next phase is the compiler
this phase will generate the equivalent assembly language code and the
compiler is responsible for this translation thereafter this assembler will
generate. relocatable machine code. Compilers it has six different phases
these are lexical analysis syntax analysis then the semantic analysis phase
after that the intermediate code generation phase and the code optimization
phase are called the backend. The last one that is the linker and loader
generate the absolute machine code that is actually the executable machine
code.
The proposed syllabus will have seven different chapters now since it is not
a basic course in order to study compiler design the learners need to have a
basic understanding of the subject theory of computation. All college and
university students can take this course because this course will be taught
comprehensively next any aspirant willing to take part in any competitive
exam will be able to lucidly understand.
In order to convert the human readable source code into machine code we
need a language translator. The language translator has got four different
