Hi Tanya, I see the following warnings when building. I'm not sure how to fix any of them. The last one looks like it might be serious (seems like a job for Chris). llvm[1]: Compiling Path.cpp for Release build In file included from Path.cpp:270: Unix/Path.inc: In member function ‘bool llvm::sys::Path::eraseFromDisk(bool, std::string*) const’: Unix/Path.inc:661: warning: ignoring return

OK, the code for sdivrem in APInt.h is wrong. Here's what's written: static void sdivrem(const APInt &LHS, const APInt &RHS, APInt &Quotient, APInt &Remainder) { if (LHS.isNegative()) { if (RHS.isNegative()) APInt::udivrem(-LHS, -RHS, Quotient, Remainder); else APInt::udivrem(-LHS, RHS, Quotient, Remainder); Quotient =

Works for me. Presumably #including <cassert> will fix it though?

I did a RelWithDebInfo + asserts build of LLVM just now and, when running "make check" under Valgrind, am seeing a lot of uses of uninitialized memory like the one below. Anyone know offhand what's likely to be the root cause? Unfortunately a Debug build doesn't give these errors. Thanks, John FAIL: LLVM :: Analysis/BasicAA/pr18573.ll (2093 of 18733)
