amd64 arch and optimization flags?

[Jaromír Mikeš <mira.mikes@gmail.com>]

Hi all,

I would like to add some optimization flags for amd64 arch in some packages (mostly LV2 nad LADSPA plugins).

I found these as candidates for amd64 arch:

-msse
-msse2
-mfpmath=sse
-ffast-math
-ftree-vectorize
-mtune=generic

Can some of them be safely added for amd64 or is just bad idea?

Some for other archs?

best regards

mira
