In order to reduce the number of passes in a compiler, all symbols have to be fully declared and defined before they are referenced. That's assuming, of course, that you would want to write a single pass compiler to start with. Most current compilers are very good at what they do, and reinventing the wheel, other than for a computer science class, is meaningless.
What else can I help you with?
Why single pass compiler are faster than multi pass 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.
How many types of compiler naming in list?
cross compiler . hybird compiler . post compiler. ideal compiler. intelligence compiler.
What are the difference between a compiler design and a compiler?
In Compiler there is no design word ,whereas in compiler design there is design word
What is cross compiler?
A cross-platform compiler can compile applications for multiple platforms, such as Windows, Linux, and Mac. An open-source cross-platform compiler is GCC (the GNU C Compiler). A cross-platform compiler uses a language that can be compiled on to multiple targets, such as C, C++, or haxe. It is required to compile the same source code multiple times, one for each target platform; a program such as make can be used to reduce the number of commands the user actually executes to just a single command.

What is passed on?
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.
Which are the factors that decide number of passes for a compiler?
There are many. I have encountered compilers with as few as 2 passes to as many as 63 passes (this number of passes were necessitated by the very tiny magnetic core memory of the machine). I even encountered a compiler that the programmer that wrote it claimed was a 1 pass compiler, but on detailed examination all he had done was "piped" the output of pass 1 to the input of pass 2 (instead of writing it to an intermediate file between passes), so it was actually a 2 pass compiler. I have also encountered a language (the US Navy's CMS-2) that has both syntactic and semantic ambiguities that made it impossible to write a compiler (no matter how many passes) that could reliably compile all code given to it, to do what the programmer intended.

It is possible to build a C compiler on top of a C compiler?
It is possible to build a C compiler on top of a C compiler. From the directory, run the shell script.
Why you call as cousins of compiler?
"Cousins" of the compiler are those things related to the compiler, and may or may not be part of the compiler. This includes: preprocessors, assemblers, linkers, and interpreters.
