Under certain circumstances, my compiler outputs basic blocks having the same function: bb_97: ; preds = %bb_1 %476 = getelementptr inbounds %LMtop.I0.ARType, %LMtop.I0.ARType* %0, i64 0, i32 6 %477 = bitcast i8** %476 to %LBstd.Cprocess.CRType** %478 = load %LBstd.Cprocess.CRType*, %LBstd.Cprocess.CRType** %477, align 8 %479 = getelementptr

Hi, I'm trying to write some forward constant propagation of sprintf and friends, and I need a way to construct a (build) va_list from the IR of a variadic function so that I can evaluate it at build time. I can't find a standard way of doing this. -- --- Shawn Landden +1 360 389 3001 (SMS preferred)

Dear all, I have re-written the proposal for interfacing user provided vector functions, originally posted in both llvm-dev and cfe-dev mailing list: "[RFC] Expose user provided vector function for auto-vectorization." The proposal looks quite different from the original submission, therefore I took the liberty to start a new thread. The original thread generated some good
