Method Detail

recordMark

public CompilationResult.CodeMark recordMark(CompilationResult.MarkId id)

Description copied from class: CompilationResultBuilder

Associates markId with the current assembler position in the compilation result.

Overrides:

recordMark in class CompilationResultBuilder

Returns:

the recorded entry for the mark

injectTailCallCode

protected abstract void injectTailCallCode(int installedCodeOffset,
                                           int entryPointOffset)
