Field Detail

STRONGARM

public static final String STRONGARM

StrongARM backend

MIPS

public static final String MIPS

MIPS backend

SPARC

public static final String SPARC

SPARC backend

PRECISEC

public static final String PRECISEC

PreciseC backend. In this case, the compiler generates C files, full of data layout information to support precise garbage collectors.

Method Detail

getFrame

public static Frame getFrame(String backendName,
                             HMethod mainMethod,
                             AllocationStrategyFactory asFact)

Create a frame object, given the name of a backend.

Parameters:

backendName - string name of the backend

mainMethod - main method of the compiled program

asFact - factory that produces the AllocationStrategy for compiling allocation sites. Currently, relevant only for the PreciseC backend.

getFrame

public static Frame getFrame(String backendName,
                             HMethod mainMethod)

Create a frame object, given the name of a backend.
