Dear devs, I upgraded inline-java [1] to use GHC 9.10.2 recently. inline-java has a GHC plugin responsible for embedding JVM bytecode in Haskell modules. This message is to consult on the most appropriate way to do it. The byte code is placed in a C literal array of bytes, and the C code is added in mg_foreign together with C constructor functions that run when loading the module to add the bytecode to a global bytecode table [2]. The global bytecode table is then fed to the JVM when initializing inline-java. The GHC API in 9.10.2 requires creating a CStub which does have a field to indicate constructor functions [3], but I wouldn't know how to create the CLabels it needs. So instead, I just put the constructor functions in the getCStub field, and set getInitializers to an empty list. The constructor functions seem to run at initialization just the same. Should inline-java do this differently? Thanks in advance! Facundo [1] https://github.com/tweag/inline-java [2] https://github.com/tweag/inline-java/blob/c6b590c29ef9190164dec3a235b8e386c5...
