Re: [gentoo-user] Gcc 5.3

[Alan Grimes]

It has been many moons since I got into compiling a compiler but here's
how it basically works:


 STAGE 1:

Compile the new compiler with whatever broken crap compiler is already
installed/hacked together/manually entered by punch cards/etc...

STAGE 2:

Compile the new compiler with whatever came out of stage 1.

STAGE 3:

As a sanity check, compile the new compiler a third time with whatever
came out of stage 2

Because stage 1 should have produced a fully updated compiler, it's
output (stage 2) should be identical to what that compiler in turn
produced (Stage 3).

This is where it's failing for me.

IQ is a measure of how stupid you feel.
