Build Errors in Code Generated from Renesas RA6M3 SVD

[AddisonH]

Hello, I am seeing many errors when attempting to build a PAC from a Renesas RA6M3 SVD file. I've already fixed some errors that I found in the Renesas provided file. I've attached the modified file below.

R7FA6M3AH.svd.txt

Here is a sample of the errors that I'm seeing:

Error E0412

error[E0412]: cannot find type `P40pfs` in this scope
    --> src\pfs.rs:68:15
     |

Error E0599

error[E0599]: the method `variant` exists for struct `FieldWriter<'a, REG, 11, Fh, Safe>`, but its trait bounds were not satisfied

...
312 |     FI: IsEnum,
    |         ^^^^^^ unsatisfied trait bound introduced here
note: the trait `generic::IsEnum` must be implemented
   --> src\generic.rs:54:1
    |
54  | pub trait IsEnum: FieldSpec {}
    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Here is the full log:
cargo_check.txt

I've tested this SVD file with several versions of svd2rust. I found that version 0.30.x works without error, but I begin to have trouble starting with version 0.31.x and up. These error logs are from the latest tagged version, v 0.33.4.

Here is my PAC that I'm working on:
ra6m3-pac.zip

Please let me know if I can offer up any more detail or assist with debugging. Thanks.

It looks like 2 main issues here:

1st was introduced in #692. Looks like:

error[E0592]: duplicate definitions with name `p400pfs`
    --> src/pfs.rs:1050:5
     |
1045 |     pub const fn p400pfs(&self, n: usize) -> &P400PFS {
     |     ------------------------------------------------- other definition for `p400pfs`
...
1050 |     pub const fn p400pfs(&self) -> &P400PFS {
     |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ duplicate definitions for `p400pfs`

There should be pub const fn p40pfs(&self, n: usize) -> &P40PFS on 1045. Register description:

                <register derivedFrom="P100PFS">
                    <dim>10</dim>
                    <dimIncrement>0x4</dimIncrement>
                    <dimIndex>0-9</dimIndex>
                    <name>P40%sPFS</name>

                    <size>32</size>
                    <access>read-write</access>
                    <resetValue>0x00000000</resetValue>
                    <resetMask>0xFFFFFFFD</resetMask>
                </register>

2nd is related to special case not covered in #767.
EnumeratedValues with only one isDefault value.
