[LLVMdev] Interesting post increment situation in DAG combiner
...__attribute__ ((aligned (16))) *A,
short __attribute__ ((aligned (16))) val)
{
unsigned i,j;
for (i=0; i<N; i++) {
for (j=0; j<N; j++) {
A[i*N+j] += val;

}
The innermost loop looks like this right before the DAG selection begins.

[LLVMdev] parallel loop metadata simplification
Hi,
I've been working on clang codegen for #pragma ivdep and creating the llvm.mem.parallel_loop_access metadata seems quite difficult. The main problem is that there are so many places where loads and stores are created and all of them need to be changed when emitting a parallel loop. Note that creating llvm.loop.parallel is not a problem.
One option is to modify IRBuilder to enable
