Bug ID: 59959
Summary: [Regression 4.9] LRA ICEs on a fortran case(Suspected
to be similar to pr59915)
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: belagod at gcc dot gnu.org
Hi,
On AArch64, I'm seeing a fortran regression that I get when I compile:
.../aarch64-none-linux-gnu/obj/gcc4/gcc/testsuite/gfortran3/../../gfortran
-B.../aarch64-none-linux-gnu/obj/gcc4/gcc/testsuite/gfortran3/../../
-B.../aarch64-none-linux-gnu/obj/gcc4/aarch64-none-linux-gnu/./libgfortran/
.../gcc/gcc/testsuite/gfortran.dg/namelist_70.f90 -fno-diagnostics-show-caret
-fdiagnostics-color=never -O0 -pedantic-errors
-B.../aarch64-none-linux-gnu/obj/gcc4/aarch64-none-linux-gnu/./libgfortran/.libs
-L.../aarch64-none-linux-gnu/obj/gcc4/aarch64-none-linux-gnu/./libgfortran/.libs
-L.../aarch64-none-linux-gnu/obj/gcc4/aarch64-none-linux-gnu/./libgfortran/.libs
-lm -o ./namelist_70.exe
This is similar to PR59915, but the same fix does not seem to fix the fortran
regression.
