- Reply-to: gcc-bugzilla at gcc dot gnu dot org
With gcc 4.6:
gfortran -c -o diis.fppized.o -O3 -fno-tree-pre -march=amdfam10 -m64
diis.fppized.f90
diis.fppized.f90: In function 'extrapolate':
diis.fppized.f90:882:0: internal compiler error: vector VEC(vec_void_p,base)
index domain error, in vinfo_for_stmt at tree-vectorizer.h:595
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions
This is invoked in "vect_recog_dot_prod_pattern":
stmt_vinfo = vinfo_for_stmt (stmt);
Where "stmt" is not inside the loop, and thus stmt_vinfo was not set up.
