improving speed
Along these lines, I'd like to see C++ about 4x faster. I'd be happy
with 2x faster[1], anything less, well, isn't interesting. I'd like
for the SC to find and appoint such a person to tackle speed
problems.
So far, it isn't happening...
1 - Assumes no regressions...
C++ has been improved for 3.4 compared to even 2.95.3. One we are
more standards
complaint. Two, speed also has decreased (at least in the last three
days, mostly thanks
to Jan Hubicka). Optimization speed has also decreased also. Looks
like you are
volunteering for the position of speeding up C++.
Okay I am going to rewrite this one more time and try again at what I
am really trying to
say.
Compile time speed has been decreased in the last three days, mostly
thanks to Jan
Hubicka. Jan is improving both speed of the compiler while optimizing
and also with no
optimizations. Also it looks like you are volunteering to help out,
why do you not
propose a patch or two to help the effect here, I already posted some
of my like six
months ago.
Thanks,
Andrew Pinski
