I hate this slowness. There's no reason IMO that GCC couldn't be 4
times faster than it is, without any PCH or anything. A lot of the
code we use is just awfully inefficient. And people are working on
more interesting things than fixing some of the real problems we have.
There's no excuse for the parser taking more time than CPP for example;
currently it takes about 4-5 times as long. I want to see GCC so fast
that CPP is up to 5-10% of CPU time. It's rarely much above 1 or 2%.
