# Interface: com.pnfsoftware.jeb.core.units.code.asm.decompiler.ir.IEUntranslatedInstruction

Special IR statement that can be used to wrap non\-standard, partially translated, or untranslated native code instructions. The untranslated native instruction can be seen as a blackbox; the IR EUntranslatedInstruction can be seen as a variant of ECall. 

 By default, IR\-Evaluation fails and C\-Generation yields basic boilerplate. Both can be customized in the converter. 

 Default [memory access information](#getMemoryAccessInfo()) is set to NONE and can be customized.

## Static Field: TAG_CUSTOM_NAME
Type: `java.lang.String`

Constant value: `CUSTOM_NAME`
Description: Tag name for an optional entry holding the custom name of this untranslated IR, possibly better suited than the native mnemonic name. 

 Value: String.
