Bug #: 11607
Summary: undefined references in libLLVMTarget.so
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Target Description Classes
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Linking CXX executable ../../bin/opt
../../lib/libLLVMTarget.so: undefined reference to
`llvm::TargetInstrInfo::getOperandLatency(llvm::InstrItineraryData const*,
llvm::SDNode*, unsigned int, llvm::SDNode*, unsigned int) const'
../../lib/libLLVMTarget.so: undefined reference to
`llvm::TargetInstrInfo::getInstrLatency(llvm::InstrItineraryData const*,
llvm::SDNode*) const'
collect2: ld returned 1 exit status
make[2]: *** [bin/opt] Error 1
make[1]: *** [tools/opt/CMakeFiles/opt.dir/all] Error 2
make: *** [all] Error 2
In include/llvm/Target/TargetInstrInfo.h, I see
virtual int getOperandLatency(const InstrItineraryData *ItinData,
const MachineInstr *DefMI, unsigned DefIdx,
const MachineInstr *UseMI, unsigned UseIdx)
const;
virtual int getOperandLatency(const InstrItineraryData *ItinData,
SDNode *DefNode, unsigned DefIdx,
SDNode *UseNode, unsigned UseIdx) const;
and
virtual int getInstrLatency(const InstrItineraryData *ItinData,
const MachineInstr *MI,
unsigned *PredCost = 0) const;
virtual int getInstrLatency(const InstrItineraryData *ItinData,
SDNode *Node) const;
but only MachineInstr-versions are implemented in
lib/Target/TargetInstrInfo.cpp
