Hi Frédéric
which are ?
Which vary depending on your platform and GCC version. Please refer to the
GCC documentation for your platform.
The platform was already specified (in the /proc/cpuinfo quotation) as
pentium4. As no indication was given of which gcc options were
considered, reference to documentation is indicated.
I noticed yesterday that past distinctions between -march=pentium4 and
-march=pentium-m don't appear to persist in gcc-4.5. pentium4 no longer
implies -mfpmath=sse (don't know if it was meant to do so). I don't
have a lot of confidence in finding such distinctions fully documented
for each gcc version.
I do want to give people credit for not jumping in and recommending
-ffloat-store without information about OP's intentions.
