[LLVMdev] Problem with LoopDependenceAnalysis
Hi,
I am using LLVM for implementing LoopFission pass.
I am using LoopPass.
I know that for checking circular dependency in loop I have to use
LoopDependenceAnalysis
This is what i want to do.
for(int i = 0; i< n ; i++){
s1 : a[i] = a[i] + x[i];
s2 : x[i] = x[i+1] + i*2 ;
}
/**there is no dependence from s2 to s1/
so after distribution(it
