C can essentially be "streamed" in separate passes:
cpp->cc->asm->linking
If compiling C is slow, it is just the compiler or the build
system,
not the language.
Yes really, specially when comparing with Turbo Pascal, Delphi,
Modula-2, Oberon and a few other languages not tied to UNIX
linker
model.
yes, i remember lightning fast compile times with turbo pascal.
yet the
code it produced was really awful: it was even unable to fold
constants
sometimes!
No different from other MS-DOS C compilers.
Hence why such languages were the Pythons and Rubys of the day
and anyone that cared about performance was using straight
Assembly, in MS-DOS and other home systems, that is.
Michael Abrash books The Zen of Assembly Language and Zen of
Code Optimization were published in 1990 and 1994 respectively.
