> Thanks for reporting. I'll change the name regexps to be more general, but I wonder why it's happening? I'd thought the command line was suitably specific, though I'm using configure+make. It'd be a bit concerning if the choice of build system changed the compiler at all.

In general, each Instruction's name is affected by
--enable-assertions, aka, NDEBUG.

See also clang/lib/CodeGen/CGBuilder.h

// Don't preserve names on values in an optimized build.
#ifdef NDEBUG
typedef llvm::IRBuilder<false> CGBuilderTy;
#else
typedef llvm::IRBuilder<> CGBuilderTy;
#endif
