  A few people asked me about new performance comparison of latest GCC
and LLVM.  So I've finished it and put it on my site

http://vmakarov.fedorapeople.org/spec/

  The comparison is achievable from 2014 link and links under it in
the left frame.

  These pages are also achievable as

http://vmakarov.fedorapeople.org/spec/2014/2014.html -- what I
compare, my motivation, major results, and my conclusions.

http://vmakarov.fedorapeople.org/spec/2014/llvmgcc64.html -- The
results of comparison on x86-64 SPECInt2000

http://vmakarov.fedorapeople.org/spec/2014/arm.html -- The
results of comparison on ARM SPECInt2000

  If you need exact numbers they can be found in the tables.

  If you have any comments and proposals, please feel free to write
me.  I try to take them into account next year.
