Detailed Description

Represents an assembler input file.

Author:
Wolfgang Wieser ] wwieser (a) gmx <*> de [
Contains all information in one assembler input file (either plaintext or binary assembly).

This class is NOT C++-safe.

VM::AssemblerFile::~AssemblerFile (   )  [virtual]
 

Destructor frees everything including the info tree and program memory.

int VM::AssemblerFile::ParseFile (  const TLString &  fname,
SError &  error,
uint32  file_num
)  [virtual]
 

Read in an assembler file.

Read in file named fname; errors during opening are returned in error, parse errors are reported directly to the user.

Note: Only one file may be read in. You need to use multiple AssemblerFile objects for more than one file.

file_num is a serial number for the file used to make non-exported symbol names unique.

Returns number of errors.

Reimplemented in VM::AssemblerFile_Plaintext.

Definition at line 235 of file asmfile.cc.

References CritAssert, and uint32.

int VM::AssemblerFile::ResolveIDsNamespaceLocal (   ) 
 

Resolve/lookup all TypeIDs and SymRefs in the namespace tree.

This will resolve all TypeIDs in all namespace nodes in the tree (i.e. class base entries) but not in the program section. Also, all SymRefs in the vtables and global vars of the file as well as the SymRef labels (i.e. symref entries in ProgramStorage::Function) will be resolved into SymbolEntry's.

This means, that after the call, the ID-and-Pointer unions hold the correct value in the pointer member and the ID member is invalid (see ClassInfo::VTableEntry, ClassInfo::BaseEntry).

Returns number of errors.

int VM::AssemblerFile::WriteFile (  const TLString &  fname,
SError &  error
)  [virtual]
 

Write an assembler file.

This function will write the current content of the class to the passed assembler file. Possible file IO error is returned in the SError object.

Returns 0 on sucess, non-zero on failure.

Reimplemented in VM::AssemblerFile_Plaintext.
