Hello world,
the below patch solves a PR (a regression if you just count -O)
by setting the AUTOMATIC flag on all variables generated
by the front end.
OK for trunk and backport?
Yes, thanks Thomas.
Best regards,

PR fortran/106546 - inline matmul with -fno-automatic
There was a problem caused with allocatable arrays used for
front-end optimization when -fno-automatic was specified.
Solved by explicitly setting the automatic attribute on the
symbol. It required "-O2 -fcheck=bounds -fno-automatic"
to be seen.
gcc/fortran/ChangeLog:
PR fortran/106546
* frontend-passes.cc (create_var): Set attr->automatic on
new symbol.
(create_do_loop): Likewise on iteration variable.
gcc/testsuite/ChangeLog:
PR fortran/106546
* gfortran.dg/inline_matmul_27.f90: New test.
