- support DICompileUnit
- support DIFIle
- support DISubroutine
- support DIBasicType
- support DILocation
- added gradle build
- debug info bindings are involved in kotlin build
- added binding to DIGetSubprogramLinkName
- added binding to LLVMBuilderGetCurrentFunction
- added reset location
- simple demo added (buildable with gradle)
produces folowing output:
