Summary: AlphaRegisterInfo.cpp:306:52: warning: array subscript
is above array bounds
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
According to gcc-4.5:
lib/Target/Alpha/AlphaRegisterInfo.cpp: In member function 'virtual void
llvm::AlphaRegisterInfo::emitEpilogue(llvm::MachineFunction&,
llvm::MachineBasicBlock&) const':
lib/Target/Alpha/AlphaRegisterInfo.cpp:306:52: warning: array subscript is
above array bounds
The line in question is this:
Msg << "Too big a stack frame at " + NumBytes;
Presumably here "+" is pointer addition, resulting in a pointer
into the string. At this point in the code gcc knows that NumBytes
is quite big (NumBytes > IMM_HIGH), so probably sees that this results
in pointing beyond the end of the string.
This is not the only place with this "Msg << c_string + Integer;"
construction, but is probably the only one where gcc knew that the
offset is always large.
