Detailed Description

This class stores information about jump-instruction tables created by the JumpInstrTables pass (in lib/CodeGen/JumpInstrTables.cpp). Each table is a map from a function type to a vector of pairs. The first element of each pair is the function that has the jumptable annotation. The second element is a function that was declared by JumpInstrTables and used to replace all address-taking sites for the original function.

The information in this pass is used in AsmPrinter (lib/CodeGen/AsmPrinter/AsmPrinter.cpp) to generate the required assembly for the jump-instruction tables.

Member Function Documentation

const char* llvm::JumpInstrTableInfo::getPassName ( ) const [inline, override, virtual]

getPassName - Return a nice clean name for a pass. This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

Reimplemented from llvm::Pass.

Definition at line 42 of file JumpInstrTableInfo.h.

const JumpTables& llvm::JumpInstrTableInfo::getTables ( ) const [inline]

Gets the tables.
