PcodeParser

protected PcodeParser(SleighBase sleigh)

PcodeParser

public PcodeParser(java.lang.String sleighSpec)
            throws org.jdom.JDOMException

Build parser from a translator string

Parameters:

sleighSpec - sleigh translator spec including address-spaces and register definitions, see SleighLanguage#buildTranslatorTag(ghidra.program.model.address.AddressFactory, long, ghidra.app.plugin.processors.sleigh.symbol.SymbolTable, boolean)

Throws:

org.jdom.JDOMException

Method Detail

addOperand

public void addOperand(Location loc,
                       java.lang.String name,
                       int index)

Inject a symbol representing an "operand" to the pcode snippet. This puts a placeholder in the resulting template, which gets filled in with the context specific storage locations when final p-code is generated

Parameters:

name - of operand symbol

index - to use for the placeholder

addSymbol

public void addSymbol(SleighSymbol sym)

Specified by:

addSymbol in class PcodeCompile

clearSymbols

public void clearSymbols()

allocateTemp

public long allocateTemp()

Specified by:

allocateTemp in class PcodeCompile

createMacroUse

public VectorSTL<OpTpl> createMacroUse(Location location,
                                       MacroSymbol sym,
                                       VectorSTL<ExprTree> param)

Specified by:

createMacroUse in class PcodeCompile

sym - MacroSymbol

Returns:

findSymbol

public SleighSymbol findSymbol(java.lang.String nm)

Specified by:

findSymbol in class PcodeCompile

getConstantSpace

public AddrSpace getConstantSpace()

Specified by:

getConstantSpace in class PcodeCompile

getDefaultSpace

public AddrSpace getDefaultSpace()

Specified by:

getDefaultSpace in class PcodeCompile

getUniqueSpace

public AddrSpace getUniqueSpace()

Specified by:

getUniqueSpace in class PcodeCompile

recordNop

public void recordNop(Location location)

Specified by:

recordNop in class PcodeCompile

stringifyTemplate

public static java.lang.String stringifyTemplate(ConstructTpl ctl)

compilePcode

public ConstructTpl compilePcode(java.lang.String pcodeStatements,
                                 java.lang.String srcFile,
                                 int srcLine)
                          throws SleighException

Compile pcode semantic statements.

Parameters:

pcodeStatements -

srcFile - source filename from which pcodeStatements came (

srcLine - line number in srcFile corresponding to pcodeStatements

Returns:

ConstructTpl. A null may be returned or an exception thrown if parsing/compiling fails (see application log for errors).

Throws:

SleighException - pcode compile error

newSectionSymbol

public SectionSymbol newSectionSymbol(Location where,
                                      java.lang.String text)
