[LLVMdev] What would LLVM need to do this optimization?
...i);
if (argc < 4) i++; else i = foo(i);
return i;
It gets optimized to just..
return 4;
opt -atomic-region-clone -mem2reg -predsimplify -simplifycfg -instcombine
.. where -atomic-region-clone is a pass I've written (-mem2reg to
clean up the PHIs I reg2mem'd). My pass inserts a custom atomic_begin
instruction and a couple intrinsics to help start/rollback a region of
code.
The optimized .ll code is roughly..
entry:
; start an atomic region at %atomic, rollback to %original_code
atomic_begin label %atomic, %original_code
atomic:
%c = icmp slt i32 %argc, 1
br i1 %c, label %done, labe...
