No.  Compilation inefficiency directly harms programmer efficiency and the
quality and volume of code the programmer produces.  These are surely the
most important things by which a toolchain's usefulness should be judged.

I compile with -O1 all the time and couldn't care the teeniest little bit
about the performance of the generated code - it just doesn't matter.

I'm happy allowing those thousands of people who do not compile kernels all
the time to shake out any 3.2/3.3 compilation problems.

Compilation inefficiency is the most serious thing wrong with gcc.
