Method Detail

getMarkName

public String getMarkName(CompilationResult.Mark mark)

Description copied from interface: CodeCacheProvider

Gets a name for a CompilationResult.Mark mark.

Specified by:

getMarkName in interface CodeCacheProvider

getTargetName

public String getTargetName(CompilationResult.Call call)

Decodes a call target to a mnemonic if possible.

Specified by:

getTargetName in interface CodeCacheProvider

getRegisterConfig
