If you compile a new version of compiler, how many times should you recompile it iteratively?
First: compile the new version of compiler[1] using the old version[0].
Second: compile the new version[2] using the newly compiled one[1], to apply new optimizations and fix bugs to the binary, not present in old[0] compiler.
Now third? Compile again, using [2] to remove any potential bugs that could have resulted from bugs in [1] as result of faulty compilation by buggy [0]...?
...but if you're paranoid, maybe the bugs introduced by [0] into [1] caused [2] to be somewhat buggy too...?
Does going beyond [2] make sense at all?

Following are the different types of Compiler: Single Pass Compilers. Two Pass Compilers. Multipass Compilers.
Compiler pass are two types: Single Pass Compiler, and Two Pass Compiler or Multi Pass Compiler. These are explained as following below.
It's kinda hard to quantify this... it depends a lot on your machine but the Linux Kernel can take half an hour to compile, OpenOffice used to take over an hour, and even Firefox took a good amount of time. 1000 lines is almost nothing in terms of software complexity.
There are three basic steps involved in compiling a C program: preprocessing, compilation of C source code to machine code (or assembly) (also called object code), and linking of multiple object files into a single binary executable program.
I'd stop when the result of compilation n is identical to the result of compilation n - 1; at that point you've reached steady state.
