Enum explicit descriminant collision

[Slesarew]

After running the tool for EFM32PG23B310 devices (like ones used in https://github.com/efm32-rs/efm32pg-pacs/tree/master/svd/EFM32PG23 or those on keil.com, does not matter) I end up with chunks of code like this:

#[doc = "Configure transition action in normal mode\n\nValue on reset: 0"]
#[derive(Clone, Copy, Debug, PartialEq, Eq)]
#[repr(u8)]
pub enum PRSACT_A {
    #[doc = "0: No PRS output generated (if PRSCOUNT == 0), or do not count (if PRSCOUNT == 1)."]
    NONE = 0,
    #[doc = "1: Pulse generated on LESENSE PRS output 0 (if PRSCOUNT == 0)."]
    PRS0 = 1,
    #[doc = "1: Count Up (if PRSCOUNT == 1)."]
    UP = 1,
    #[doc = "2: Pulse generated on LESENSE PRS output 1 (if PRSCOUNT == 0)."]
    PRS1 = 2,
    #[doc = "2: Count Down (if PRSCOUNT == 1)."]
    DOWN = 2,
    #[doc = "3: Pulse generated on LESENSE PRS output 0 and 1 (if PRSCOUNT == 0)."]
    PRS01 = 3,
    #[doc = "4: Pulse generated on LESENSE PRS output 2. (PRSCOUNT == 0 OR 1)."]
    PRS2 = 4,
    #[doc = "5: Pulse generated on LESENSE PRS output 0 and 2 (if PRSCOUNT == 0)."]
    PRS02 = 5,
    #[doc = "5: Count Up and Pulse generated on LESENSE PRS output 2 (if PRSCOUNT == 1)."]
    UPANDPRS2 = 5,
    #[doc = "6: Pulse generated on LESENSE PRS output 1 and 2 (if PRSCOUNT == 0)."]
    PRS12 = 6,
    #[doc = "6: Count Down and Pulse generated on LESENSE PRS output 2 (if PRSCOUNT == 1)."]
    DOWNANDPRS2 = 6,
    #[doc = "7: Pulse generated on LESENSE PRS output 0, 1 and 2 (if PRSCOUNT == 0)."]
    PRS012 = 7,
}

which results in hundreds of collision errors upon build:

error[E0081]: discriminant value `6` assigned more than once
  --> src/lesense_ns/st63_arc.rs:54:1
   |
54 | / pub enum PRSACT_A {

56 | |     NONE = 0,
57 | |     #[doc = "1: Pulse generated on LESENSE PRS output 0 (if PRSCOUNT == 0)."]
...  |
74 | |     PRS12 = 6,
   | |             - first assignment of `6`
75 | |     #[doc = "6: Count Down and Pulse generated on LESENSE PRS output 2 (if PRSCOUNT == 1)."]
76 | |     DOWNANDPRS2 = 6,
   | |                   - second assignment of `6`
77 | |     #[doc = "7: Pulse generated on LESENSE PRS output 0, 1 and 2 (if PRSCOUNT == 0)."]
78 | |     PRS012 = 7,
79 | | }
   | |_^

I have tried passing --strict and all kinds of other underdocumented (sorry I didn't find any clear explanations) config keys in varying combinations and this is still the same. Maybe it is related to #283 or #636 issues. It might be caused by #402

Similar issue seems to be present in abovelinked crate.

svd configs for STM32 devices build without issues with my setup.

Your SVD have several entries in enums with identical values. It is not supported and will not be:

You need to delete those before start svd2rust. All listed above issues and PRs are not related to this one.

Thank you, it's on my side indeed! I didn't expect the silabs to be this mean in their definitions. Sorry for confusion. I probably should not be using vendor-made svd files after all.
