Bug ID: 67923
Summary: [6 Regression] ICEs in the gfortran test suite with
-flto after r228680
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: dominiq at lps dot ens.fr
CC: hubicka at gcc dot gnu.org, pault at gcc dot gnu.org,
rguenth at gcc dot gnu.org
Target Milestone: ---
Compiling the following tests with -flto on top of the other options gives ICEs
FAIL: gfortran.dg/allocatable_function_1.f90 -g -flto (internal compiler
error)
FAIL: gfortran.dg/forall_10.f90 -g -flto (internal compiler error)
FAIL: gfortran.dg/pr56015.f90 -g -flto (internal compiler error)
FAIL: gfortran.dg/transfer_simplify_2.f90 -g -flto (internal compiler error)
FAIL: gfortran.dg/trim_optimize_3.f90 -g -flto (internal compiler error)
FAIL: gfortran.dg/trim_optimize_7.f90 -g -flto (internal compiler error)
for both -m32 and -m64. The test
FAIL: gfortran.dg/pr46804.f90 -g -flto (internal compiler error)
fails only with -m32.
The ICEs are of the kind
