public class InlineAssembly
extends JStatement

Statement used for generating inline assembly. Leverages gcc's asm volatile keyword. Mostly holds Strings that are passed directly to codegen but is structured slightly to allow automatic generation of the appropriate asm volatile statement. See spacetime/TraceIRtoC for example of how the output should be formatted. May hold a whole block of assembly instructions.

Constructor Detail

InlineAssembly

public InlineAssembly()
Construct InlineAssembly containing no instructions.


InlineAssembly

public InlineAssembly(String asm)
Construct InlineAssembly containing the initial instruction asm.

Parameters:
asm - The initial instruction to include.
Method Detail

add

public void add(String instr)
Add single instruction.

Parameters:
instr - The instruction to add.

addInput

public void addInput(String input)
Add input to instruction block. Input may be label of memory location. Inputs should be added in order they are used in instruction block.

Parameters:
input - The input label to add.

addClobber

public void addClobber(String clobber)
Add register clobbered by this instruction block. This is to allow gcc to register allocate correctly.

Parameters:
clobber - The register to add.

getInstructions

public String[] getInstructions()
Returns list of instructions.


getInput

public String[] getInput()
Returns list of input labels.


getClobber

public String[] getClobber()
Returns list of clobbered registers.


accept

public Object accept(AttributeVisitor p)
Dummy method to accept AttributeVisitor but not do anything. InlineAssembly should be blackbox to everyone but codegen.

Specified by:
accept in class JStatement
Parameters:
p - the visitor

genCode

public void genCode(CodeSequence code)
Dummy method for genCode(CodeSequence). This is not needed by InlineAssembly.

Specified by:
genCode in class JStatement
Parameters:
code - the code list

analyse

public void analyse(CBodyContext context)
Dummy method for analyse(CBodyContext context). This is not needed by InlineAssembly.

Specified by:
analyse in class JStatement
Parameters:
context - the analysis context

accept

public void accept(KjcVisitor p)
Main entry point for KjcVisitor. For SLIREmptyVisitor, forwards to p.visitInlineAssembly(this,getInstructions(),getInput(),getClobber()).

Overrides:
accept in class JStatement
Parameters:
p - the visitor
