Using custom calling conventions when creating function definitions

[0xBEEEF]

I currently have a strange behavior and am currently unsure if this is a bug or if I am simply doing something wrong.

During my analysis I have defined my own calling conventions. I can also select these when I edit functions and assign them to them. They are also used in the decompiler itself.

But now I have the problem that I have indirect function calls in the code, which are based on defined methods within a structure, in which these are contained as a member. Therefore I tried to go the way over the creation of function definitions with the help of the data type manager.

But there is a problem there now. When defining function definitions, I can only choose from a fixed list of calling conventions. See the comparison of the selection menu.

Do I have to do anything else to also be able to fall back on these calling conventions when creating function definitions? Am currently at a loss at this point, and don't know what to do.

I am using the latest released version 10.1.5 on Windows.

Am grateful for any help suggestion or solution approach.

After searching the source code, I found that the list is indeed fixed. For this reason I published a feature request with the above content under the number #4537
