--- Comment #18 from Robin Dapp <rdapp at gcc dot gnu.org> ---
Hmm, doesn't help unfortunately.  A full command line for me looks like:

x86_64-pc-linux-gnu-gcc -c -o pbeampp.o -DSPEC_CPU -DNDEBUG  -DWANT_STDC_PR=
OTO=20
-Ofast -march=3Dznver4 -mtune=3Dznver4 -flto=3D32 -g -fprofile-use=3D/tmp
-SPEC_CPU_LP64         pbeampp.c.

Could you verify if it's exactly the same for you?  Maybe it would also hel=
p if
you explicitly specified znver4?=
