Bug ID: 68432
Summary: [6 Regression] internal compiler error: in
expand_insn, at optabs.c:6947
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
Target Milestone: ---
Between r230516 and r230587, I run into an ICE, but it triggers only with
-fprofile-use making it difficult to reduce. It always involves ANINT in the
error message:
/data/vjoost/gnu/cp2k/cp2k/makefiles/../src/cell_types.F: In function ‘pbc1’:
/data/vjoost/gnu/cp2k/cp2k/makefiles/../src/cell_types.F:424:0: internal
compiler error: in expand_insn, at optabs.c:6947
r_pbc(1) = r(1) -
cell%hmat(1,1)*cell%perd(1)*ANINT(cell%h_inv(1,1)*r(1))
