[flang][FIR] add fir.assumed_size_extent to abstract assumed-size extent encoding (#164452)

2025-10-22T09:46:18+00:00

The purpose of this patch is to allow converting FIR array representation to
memref when possible without hitting memref verifier issue.

The issue was that FIR arrays may be assumed size, in which case the
last dimension will not be known at runtime. Flang uses -1 to encode
this to fulfill Fortran 2023 standard requirements in 18.5.3 point 5
about CFI_desc_t.

When arrays are converted to memeref, if this `-1` reaches memeref
operations, it triggers verifier errors (even if the conversion happened
in code that guards the code to be entered at runtime if the array is
assumed-size because folders/verifiers do not take into account
reachability).

This follows-up on discussions in #163505 merge requests

[flang] Fix `replaceAllUsesWith` API violations (1/N) (#154698)

2025-08-21T09:48:14+00:00

`replaceAllUsesWith` is not safe to use in a dialect conversion and will
be deactivated soon (#154112). Fix commit fixes some API violations.
Also some general improvements.

Reapply "[mlir] Mark `isa/dyn_cast/cast/...` member functions depreca… (#90406)

2024-04-28T20:01:42+00:00

…ted. (#89998)" (#90250)

This partially reverts commit 7aedd7dc754c74a49fe84ed2640e269c25414087.

This change removes calls to the deprecated member functions. It does
not mark the functions deprecated yet and does not disable the
deprecation warning in TypeSwitch. This seems to cause problems with
MSVC.

[flang] Retain internal and BIND(C) host procedure link in FIR (#87796)

2024-04-17T09:31:29+00:00

Currently, it is not possible to find back which fun.func is the host
procedure of some internal procedure because the mangling of the
internal procedure does not contain info about the BIND(C) name of the
host.
This info may be useful to ensure dwarf DW_TAG_subprogram of internal
procedures are nested under DW_TAG_subprogram of host procedures for
instance.

[flang][NFC] Remove hardcoded attr name for fir.global op (#81347)

2024-02-12T16:56:30+00:00

These hardcoded attribute name are a leftover from the upstreaming
period when there was no way to get the attribute name without an
instance of the operation. It is since possible to do without them and
they should be removed to avoid duplication.

This PR cleanup the fir.global op of these hardcoded attribute name and
use their generated getters. Some other PRs will follow to cleanup other
operations.
