There are two types of compilers one-pass and multi-pass. Pass means that some of inner operations are repeated several times.
If we have one-pass compiler and this source code:
i++;
i++;
i++;
Inside compiler it would generate:
i = i + 1;
i = i + 1;
i = i + 1;
If compiler would be two-pass:
i = i + 3;
The more passes compiler has, the better optimized code it can generate, but it is slower because it must repeat some steps again.
In Compiler there is no design word ,whereas in compiler design there is design word
Principles of Compiler Design was created in 1977.
-Single pass compiler -Multi pass compiler -Cross compiler -Optimizing compiler
A one-pass compiler is a compiler that passes through the source code of each compilation unit only once. A multi-pass compiler is a type of compiler that processes the source code or abstract syntax tree of a program several times.A one-pass compilers is faster than multi-pass compilersA one-pass compiler has limited scope of passes but multi-pass compiler has wide scope of passes.Multi-pass compilers are sometimes called wide compilers where as one-pass compiler are sometimes called narrow compiler.Many programming languages cannot be represented with a single pass compilers, for example Pascal can be implemented with a single pass compiler where as languages like Java require a multi-pass compiler.
i think a pass is reading the input file, i.e. the file in which the code is written in the source language.so in a single pass compiler, the input file is read only once and in doublepass compiler this is done 2 times .

-Single pass compiler -Multi pass compiler -Cross compiler -Optimizing compiler
A single pass compiler also known as a one-pass compiler is a compiler that only passes through the code once and doesn't go back. They're faster than a multi-pass compiler but they are very limited in what they can do.

bootstrapping is a process of writing a compiler in the target programing language which it is intended to compile
