Hi, dear community,
Looks like moblin's gnu compilers are trying to tune applications
performance with some specific options: -c -g -O2 -g -march=core2
-msse3 -mtune=generic -mfpmath=sse. Very nice, but it becomes a
problem when compiling with icpc intel's compiler:
icpc: command line warning #10120: overriding '-marchcore2' with '-msse3'
icpc: command line error: invalid argument for option '-m'
So, is there a solution for both to save gnu's tuning options and
provide compatibility to intel's?
Hi,
realistically, if you use a different compiler like icc, you really should use
a set of options for that compiler. The options we use for gcc for Atom
Processors,
are very much so not the right ones to use for icc for Atom Processors.
(they have specific options for Atom). The icc manual should have a table
somewhere
that lists the suggested values for different processors....
(and if not, that'd be a very good question for the ICC forums on Intel.com)
