Hi,
of course most development on gcc is applied to make the produced
binary faster. Also most benchmarks focus on the speed of the produced
binaries - you just need to look on the right benchmarks ,-)
Whether the generated binary of gcc in a new major version is faster
depends on your code and optimizations used and I have not tested
MIPS recently.
For my code new versions of GCC are usually faster, on x86-64
-frename-registers gave some extra bonus on 4.0 IIRC.
