Re: [9fans] Harvey OS: A new OS inspired heavily by Plan 9

Who claimed fast compilation was a motive?

It makes sense to me, but it might still be subjective.
If you care I will explain my experience:

Some longer time ago I tried gdb for disassembling some secret binary,
but quickly gave up cause of the complex interface and reverted to
objdump instead. I wasted a lot of time and that made me hate gdb a
lot.

Now, much later I started using gdb again, cause as long as it has
access to the source analyzing coredumps is very easy. It's a better
workflow than my printf() debugging, because the Makefiles of the
project I'm working on are so complex and broken that everybody avoids
compiling (takes too long).
I have seen many complaints in Ron's commit logs about makefiles, too.
I'm fairly certain that for Harvey and Akaros they're pretty much
forced just like me into a coredump-driven development workflow.

tldr: gcc is needed so that we can use gdb so that we don't have to
compile as often so that we can fix bugs faster.
