class ELFCodeEmitter

Detailed Description

ELFWriter - This class implements the common target-independent code for writing ELF files. Targets should derive a class from this to parameterize the output format.

bool ELFWriter::doFinalization (  Module &  M  )  [protected, virtual]
 

doFinalization - Now that the module has been completely processed, emit the ELF file to 'O'.

Reimplemented from llvm::FunctionPass.

Definition at line 353 of file ELFWriter.cpp.

References Module::global_begin(), Module::global_end(), and Mang.

bool ELFWriter::doInitialization (  Module &  M  )  [protected, virtual]
 

doInitialization - Emit the file header and all of the global variables for the module to the ELF file.

Reimplemented from llvm::FunctionPass.

bool ELFWriter::runOnMachineFunction (  MachineFunction &  MF  )  [protected, virtual]
