How do compilers manage their memory size?

Question

Compilers can compile a huge amount of source code. This giant code is translated into AST at the compilation stage. I believe that if the code is huge, this AST will also become huge.

Can we assume that the compiler will never run out of memory on a modern computer by building an AST and storing it in memory?

Answer 1

With virtual memory, the compiler / linker tools really don't have to worry much about the amount of memory.
