Subject: [PATCH 03/23] Remove unneccesary blocking for implicit cases
This was intended to allow for enter + exit data to work in conjunction
with descriptor based type mapping, but after further testing it seems
unneccesary and actually hinders the regular implicit capture case. It's
also best to keep this lowering as simple as possible for the case where
we're actually mapping a derived type/structure.

+# OpenMP dialect: Fortran descriptor type mapping for offload
+
+The descriptor mapping for OpenMP currently works differently to the planned direction for OpenACC, however,
+it is possible and would likely be ideal to align the method with OpenACC in the future. However, at least
+currently the OpenMP specification is less descriptive and has less stringent rules around descriptor based
+types so does not require as complex a set of descriptor management rules (although, in certain cases
+for the interim adopting OpenACC's rules where it makes sense could be useful).
+
+The initial method for mapping Fortran types tied to descriptors for OpenMP offloading is to treat these types
+as a special case of OpenMP record type (C/C++ structure/class, Fortran derived type etc.) mapping as far as the
+runtime is concerned. Where the box (descriptor information) is the holding container and the underlying
+data pointer is contained within the container, and we must generate explicit maps for both the pointer member and
+the container. As an example, a small C++ program that is equivalent to the concept described:
+
+```C++
+struct mock_descriptor {
+ long int x;
+ std::byte x1, x2, x3, x4;
+ void *pointer;
+ long int lx[1][3];
+};
+
+int main() {
+mock_descriptor data;
+#pragma omp target map(tofrom: data, data.pointer[:upper_bound])
+{
+ do something...
+}
+
+ return 0;
+}
+```
+
+In the above, we have to map both the containing structure, with its non-pointer members and the
+data pointed to by the pointer contained within the structure to appropriately access the data. This
+is effectively what is done with descriptor types for the time being. Other pointers that are part
+of the descriptor container such as the addendum should also be treated as the data pointer is
+treated.
+
+Currently, Flang will lower these descriptor types in the OpenMP lowering (lower/OpenMP.cpp) similarly
+to all other map types, generating an omp.MapInfoOp containing relevant information required for lowering
+the OpenMP dialect to LLVM-IR during the final stages of the MLIR lowering. However, after
+the lowering to FIR/HLFIR has been performed an OpenMP dialect specific pass for Fortran,
+OMPDescriptorMapInfoGenPass (Optimizer/OMPDescriptorMapInfoGen.cpp) will expand the
+omp.MapInfoOp's containing descriptors (which currently will be a BoxType or BoxAddrOp) into multiple
+mappings, with one extra per pointer member in the descriptor that is supported on top of the original
+descriptor map operation. These pointers members are linked to the parent descriptor by adding them to
+the member field of the original descriptor map operation, they are then inserted into the relevant map
+owning operation's (omp.TargetOp, omp.DataOp etc.) map operand list and in cases where the owning operation
+is IsolatedFromAbove, it also inserts them as BlockArgs to canonicalize the mappings and simplify lowering.
+
+An example transformation by the OMPDescriptorMapInfoGenPass:
+
+```
+
+...
+%12 = omp.map_info var_ptr(%1#1 : !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, !fir.box<!fir.ptr<!fir.array<?xi32>>>) map_clauses(tofrom) capture(ByRef) bounds(%11) -> !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>> {name = "arg_alloc"}
+...
+omp.target map_entries(%12 -> %arg1, %13 -> %arg2 : !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, !fir.ref<i32>) {
+ ^bb0(%arg1: !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, %arg2: !fir.ref<i32>):
+...
+
+====>
+
+...
+%12 = fir.box_offset %1#1 base_addr : (!fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>) -> !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>>
+%13 = omp.map_info var_ptr(%12 : !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>>, !fir.array<?xi32>) map_clauses(tofrom) capture(ByRef) bounds(%11) -> !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>> {name = ""}
+%14 = omp.map_info var_ptr(%1#1 : !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, !fir.box<!fir.ptr<!fir.array<?xi32>>>) map_clauses(tofrom) capture(ByRef) members(%13 : !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>>) -> !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>> {name = "arg_alloc"}
+...
+omp.target map_entries(%13 -> %arg1, %14 -> %arg2, %15 -> %arg3 : !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>>, !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, !fir.ref<i32>) {
+ ^bb0(%arg1: !fir.llvm_ptr<!fir.ref<!fir.array<?xi32>>>, %arg2: !fir.ref<!fir.box<!fir.ptr<!fir.array<?xi32>>>>, %arg3: !fir.ref<i32>):
+...
+
+```
+
+In later stages of the compilation flow when the OpenMP dialect is being lowered to LLVM-IR these descriptor
+mappings are treated as if they were structure mappings with explicit member maps on the same directive as
+their parent was mapped.
+
+This method is generic in the sense that the OpenMP diaelct doesn't need to understand that it is mapping a
+Fortran type containing a descriptor, it just thinks it's a record type from either Fortran or C++. However,
+it is a little rigid in how the descriptor mappings are handled as there is no specialisation or possibility
+to specialise the mappings for possible edge cases without poluting the dialect or lowering with further
+knowledge of Fortran and the FIR dialect. In the case that this kind of specialisation is required or
+desired then the methodology described by OpenACC which utilises runtime functions to handle specialised mappings

The initial method for mapping Fortran types tied to descriptors for OpenMP offloading is to treat these types
as a special case of OpenMP record type (C/C++ structure/class, Fortran derived type etc.) mapping as far as the
runtime is concerned. Where the box (descriptor information) is the holding container and the underlying
data pointer is contained within the container, and we must generate explicit maps for both the pointer member and
-the container. As an example, a small C++ program that is equivalent to the concept described:

In later stages of the compilation flow when the OpenMP dialect is being lowered to LLVM-IR these descriptor
mappings are treated as if they were structure mappings with explicit member maps on the same directive as
-their parent was mapped.
-
-This method is generic in the sense that the OpenMP diaelct doesn't need to understand that it is mapping a
+their parent was mapped.
+
+This implementation utilises the member field of the `map_info` operation to indicate that the pointer
+descriptor elements which are contained in their own `map_info` operation are part of their respective
+parent descriptor. This allows the descriptor containing the descriptor pointer member to be mapped
+as a composite entity during lowering, with the correct mappings being generated to tie them together,
+allowing the OpenMP runtime to map them correctly, attaching the pointer member to the parent
+structure so it can be accessed during execution. If we opt to not treat the descriptor as a single
+entity we have issues with the member being correctly attached to the parent and being accessible,
+this can cause runtime segfaults on the device when we try to access the data through the parent. It
+may be possible to avoid this member mapping, treating them as individual entities, but treating a
+composite mapping as an individual mapping could lead to problems such as the runtime taking
+liberties with the mapping it usually wouldn't if it knew they were linked, we would also have to
+be careful to maintian the correct order of mappings as we lower, if we misorder the maps, it'd be
+possible to overwrite already written data, e.g. if we write the descriptor data pointer first, and
+then the containing descriptor, we would overwrite the descriptor data pointer with the incorrect
+address.
+
+This method is generic in the sense that the OpenMP dialect doesn't need to understand that it is mapping a
Fortran type containing a descriptor, it just thinks it's a record type from either Fortran or C++. However,
it is a little rigid in how the descriptor mappings are handled as there is no specialisation or possibility
-to specialise the mappings for possible edge cases without poluting the dialect or lowering with further
-knowledge of Fortran and the FIR dialect. In the case that this kind of specialisation is required or

+# OpenMP dialect differences from OpenACC dialect
+
+The descriptor mapping for OpenMP currently works differently to the planned direction for OpenACC, however,
+it is possible and would likely be ideal to align the method with OpenACC in the future.
+
+Currently the OpenMP specification is less descriptive and has less stringent rules around descriptor based
+types so does not require as complex a set of descriptor management rules as OpenACC (although, in certain
+cases for the interim adopting OpenACC's rules where it makes sense could be useful). To handle the more
+complex descriptor mapping rules OpenACC has opted to utilise a more runtime oriented approach, where
+specialized runtime functions for handling descriptor mapping for OpenACC are created and these runtime
+function handles are attatched to a special OpenACC dialect operation. When this operation is lowered it
+will lower to the attatched OpenACC descriptor mapping runtime function. This sounds like it will work
+(no implementation yet) similarly to some of the existing HLFIR operations which optionally lower to
+Fortran runtime calls.
+
+This methodology described by OpenACC which utilises runtime functions to handle specialised mappings allows
+more flexibility as a significant amount of the mapping logic can be moved into the runtime from the compiler.
+It also allows specialisation of the mapping for fortran specific types. This may be a desireable approach
+to take for OpenMP in the future, in particular if we find need to specialise mapping further for
+descriptors or other Fortran types. However, for the moment the currently chosen implementation for OpenMP
+appears sufficient as far as the OpenMP specification and current testing can show.

Subject: [PATCH 22/23] [MLIR][OpenMP] Moved descriptor base_addr from varPtr
to varPtrPtr field
This required making the varPtr optional alongside varPtrPtr, and adding verification to test at least one of these was specified.
I also added the varPtrPtrType field and renamed VarType to varPtrType, so
that both fields have a distinct type (verification was also used to make sure
the respective type field was provided). This change is not completely neccesary it is likely they could share the same type, but this wouldn't
allow for both a var_ptr and var_ptr_ptr to be specified on the one
map_info operation reasonably (which is allowed currently).
The lowering and tests were also updated to reflect these changes.
