The following are the lmbench results (P3 and P4P) we tried to get. The
kernels built by gcc 3.2 were not stable for P4P, so we used an older
version of gcc.
p70 -- the kernel built by just with the -O2 optimization (Intel compiler
7.0)
pgoipo -- P70 + PGO (profile-guided optimization) + IPO (interprocedural
optimization)
inline -- pgoipo + forced inline
gcc32 -- gcc 3.2
gcc30 -- gcc 3.02

Subject: Re: [PATCH] fixes for building kernel using Intel compiler
BTW do you have any benchmark / code size results to share with
Intel compiler vs gcc 3.2 ? How much does it give ?
