Hi All,
Looking at the code of MemDepPrinter.cpp, I saw the
char MemDepPrinter::ID = 0;> INITIALIZE_PASS_BEGIN(MemDepPrinter, "print-memdeps",
> "Print MemDeps of function", false, true)
> INITIALIZE_PASS_DEPENDENCY(MemoryDependenceAnalysis)
> INITIALIZE_PASS_END(MemDepPrinter, "print-memdeps",
> "Print MemDeps of function", false, true)
What's the purpose of the INITIALIZE_PASS_* macros? What's the
difference between using static RegisterPass...?
When I try to use these macros in user-defined passes. The compiler complains,
error: ‘initializeXXXPass’ was not declared in this
scope> error: ‘void llvm::initializeXXXPass(llvm::PassRegistry&)’ should have
> been declared inside ‘llvm’
Is it because they should only be used by internal LLVM passes?
I couldn't find related hints from the documentation.
Thanks!
ryan
