While the preprocessor still exists as a separate executable, the 
preprocessing is not a separate step anymore. You can confirm that by adding -v 
to the gcc build and you'll see that it does not run cpp anymore.

In other words, the compiler will do the preprocessing step. Moreover, in 
order to do optimisations, it needs to know the entire preprocessed output, 
but I'd guess it does so in an AST form already.

The output from the compiler does jump between sections. But the output from 
the assembler doesn't, so the assembler needs to read the entire compiler 
output into memory before it can start writing out its own output.
