This code is compiled from C++ and for some functions there are no phis, but multiple call instructions. I am targeting hardware in the end, and the next tool reading the IR does not like phis when it's generating VHDL. My questions may

I am working on heavily optimising unusually static C++ code, and have encountered a situation where I basically want an optimiser that would speculatively unroll a loop to see if the first round of the loop could be optimised further. (I happen to know that it is possible.) The previous optimisations that produce the loop in the first place already do a magical job (relying heavily on constant

[I am a newcomer to llvm, so don't believe me.] Hi Claude, I added -debug to the command line in an attempt to study your example, and got out this: Loop Unroll: F[main] Loop %bb1 Loop Size = 4 Can't unroll; loop not terminated by a conditional branch. The source code for that is on line 116 (or so) in lib/Transforms/Utils/LoopUnroll.cpp Based on a quick look at the source code,

Hi all, I have tried to use the loop-unroll pass on a large example, but without success. So I have tried on smaller examples, and I did not get more success. My simplest example is attached. It comes from this C code (using llvm-gcc, but similar result with clang): int main (int argc, char *argv[]) { int i; for (i = 0; i!=5; ++i) {} return 0; } I use this command (version 2.8svn, from
