I've been following the fix proposed by Bernhard in this thread:
https://gcc.gnu.org/pipermail/fortran/2021-April/055907.html
to allow static linking of Fortran codes compiled with -fopenmp. (I know that
static linking of OpenMP codes isn't guaranteed to work, but this fix has
worked well for m
This adds support for clobbering of allocatable and pointer scalar
variables passed as actual argument to a subroutine when the associated
dummy has the INTENT(OUT) attribute.
Support was explicitly disabled, but the clobber generation code seems
to support it well, as demonstrated by the newly add
From: Harald Anlauf
Before procedure calls, we clobber actual arguments whose associated
dummy is INTENT(OUT). This only applies to procedures with explicit
interfaces, as the knowledge of the interface is necessary to know
whether an argument has the INTENT(OUT) attribute.

Hello,
this is a set of changes around the clobber we generate in the caller
before a procedure call, for each actual argument whose associated dummy
has the INTENT(OUT) attribute.
The first patch is a refactoring moving the clobber generation in
gfc_conv_procedure_call where it feels more approp
This adds support for clobbering of partial variable references, when
they are passed as actual argument and the associated dummy has the
INTENT(OUT) attribute.
Support includes array elements, derived type component references,
and complex real or imaginary parts.
This is done by removing the che
This is probably the most risky patch in the series.
A previous version of this patch allowing all exactly matching derived
types showed two regressions. One of them uncovered PR106817 for which
I added a fix in this series, and for the other I have excluded
types with allocatable components from
This adds support for clobbering of variables passed by reference,
when the reference is forwarded to a subroutine as actual argument
whose associated dummy has the INTENT(OUT) attribute.
This was explicitly disabled and enabling it seems to work, as
demonstrated by the new testcase.

For actual arguments whose dummy is INTENT(OUT), we used to generate
clobbers on them at the same time we generated the argument reference
for the function call. This was wrong if for an argument coming
later, the value expression was depending on the value of the just-
clobbered argument, and we

This change inlines the clobber generation code from
gfc_conv_expr_reference to the single caller from where the add_clobber
flag can be true, and removes the add_clobber argument.
What motivates this is the standard making the procedure call a cause
for a variable to become undefined, which trans
The fortran frontend, as result symbol for a function without
declared result symbol, uses the function symbol itself. This caused
an invalid clobber of a function decl to be emitted, leading to an
ICE, whereas the intended behaviour was to clobber the function result
variable. This change fixes
