Detailed Description

Function program instruction storage.

Author:

Wolfgang Wieser ] wwieser (a) gmx <*> de [

Stores the program instructions of one function.

The function program storage is organized in a byte-wise manner and instructions differ in size. All instructions are of even size (i.e. at least 2 bytes) and the first 2 bytes of each instruction is the instruction ID.

The function program storage internally uses the machine order (LSB/MSB first) and the machine representation for floating point numbers. For distribution over network, this must first be converted.

This class is NOT C++-safe.

SCLocation VM::ProgramStorage::Function::loc

Location in source code. Definition at line 84 of file program.h. Referenced by VM::VMLinker::_GenerateSymbolProvideMap(), VM::VMLinker::_LinkFunction(), VM::AssemblerFile_Plaintext::_ParseProgram_FinishFunction(), VM::AssemblerFile_Plaintext::_ParseProgram_Label(), VM::AssemblerFile_Plaintext::_WriteFunctionProgram(), and VM::AssemblerFile::ResolveIDsNamespaceLocal().

NamespaceInfo::SymbolEntryE* VM::ProgramStorage::Function::se

Looked-up symref. Be careful: the special .init and .start functions get *se pointer set initially because they do not have a SymRef. Definition at line 80 of file program.h. Referenced by VM::VMLinker::_CreateInitFunction(), VM::VMLinker::_GenerateSymbolProvideMap(), VM::VMLinker::_LinkFunction(), VM::AssemblerFile_Plaintext::_WriteFunctionProgram(), and VM::AssemblerFile::ResolveIDsNamespaceLocal().

SymRef VM::ProgramStorage::Function::symref

Symbol number of the function symbol of this function. Definition at line 76 of file program.h. Referenced by VM::AssemblerFile_Plaintext::_ParseProgram_FinishFunction(), and VM::AssemblerFile::ResolveIDsNamespaceLocal().
