As for my attempts, I compiled successfully a couple times and the first benchmark I did was faster than the gcc compiled server by about 10%-
unfortunately, I can't say if this is a conculsive test since the gcc binary was 3.23 and the icc binary 4.1.1 - I only managed one benchmark b/c something has broken the benchmark suite and I haven't had time to check into it...
I'll try the following and get back to you- hopefully with good news. yonah

Hi Yonah,
sorry for the late reply. I have now been finally able to install icc 8.0 on one our build hosts (Running SuSE Linux 8.2) and made some tests.

I'm trying to compile mysql 4.0.18 with icc 8.0 on RH AS 3u1. I'm including my last configuration for compiling and how it died- I've tried about a million other ways- this seems to come the closest to compiling normally but dies with an internal error(looks like intel's fault not yours). Does anyone have a configuration where this compiles? What did I do wrong?
fyi- there is a problem with the configure/libtool script when you don't compile -static and you use ipo... the compilation runs icc -shared to link the libraries but it needs the -ipo option as well.
thanks in advance for any help! yonah
here the environment variables: AR=xiar CC=icc CFLAGS='-O3 -ipo -static -axWN -march=pentium4 -mcpu=pentium4' CXX=icc CXXFLAGS='-O3 -ipo -static -axWN -march=pentium4 -mcpu=pentium4' LANG=C LD=xild PATH=/usr/local/intel/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin/X11:/usr/X11R6/bin:/root/bin:/usr/local/mysql/bin
this is the configure line:
./configure --prefix=/usr/local/mysql --enable-thread-safe-client --without-innodb --without-debug --enable-assembler --with-named-curses-libs=/usr/lib/libncurses.so.5.3
it dies with this error:

That really sounds like an icc bug. Here's the line we currently use for our binaries on icc:
CFLAGS="-O3 -unroll2 -ip -mp -no-gcc -restrict" CC=icc CXX=icc CXXFLAGS="-O3 -unroll2 -ip -mp -no-gcc -restrict" ./configure - --prefix=/usr/local/mysql --localstatedir=/usr/local/mysql/data - --libexecdir=/usr/local/mysql/bin --with-extra-charsets=complex - --enable-thread-safe-client --enable-local-infile --enable-assembler - --disable-shared --with-client-ldflags=-all-static - --with-mysqld-ldflags=-all-static --with-readline --with-embedded-server - --with-innodb
You may be able to use higher optimization levels (e.g. by removing "-mp", which will however cause some loss in floatingpoint accuracy - some of the test suite tests will fail). I assume the "--no-gcc" is key here.
Bye,
