------- Comment #12 from sascha-web-gcc dot gnu dot org at silbe dot org 2009-05-10 21:21 ------- "Geode by NSC" seems to be the "original" Geode series developed by National Semiconductor. According to Wikipedia [1], AMD bought the Geode "business", released the original design as "GX series" as well as a GX-derived "LX series" and an Athlon-derived "NX series".
My guess is that GX and LX lack ffreep, but NX does support it (because it's derived from the Athlon core). Unfortunately, unlike the LX series datasheet, the NX series one doesn't include an instruction listing, so I cannot verify this assumption. PS: -march=geode seems to be working fine (no SIGILL so far), thanks!
