6 years ago[SROA] enable splitting for non-whole-alloca loads and stores
Hiroshi Inoue [Thu, 30 Nov 2017 07:44:46 +0000 (07:44 +0000)]
[SROA] enable splitting for non-whole-alloca loads and stores

Currently, SROA splits loads and stores only when they are accessing the whole alloca.
This patch relaxes this limitation to allow splitting a load/store if all other loads and stores to the alloca are disjoint to or fully included in the current load/store. If there is no other load or store that crosses the boundary of the current load/store, the current splitting implementation works as is.
The whole-alloca loads and stores meet this new condition and so they are still splittable.

Here is a simplified motivating example.

struct record {
    long long a;
    int b;
    int c;
};

int func(struct record r) {
    for (int i = 0; i < r.c; i++)
        r.b++;
    return r.b;
}

When updating r.b (or r.c as well), LLVM generates redundant instructions on some platforms (such as x86_64, ppc64); here, r.b and r.c are packed into one 64-bit GPR when the struct is passed as a method argument.

With this patch, the above example is compiled into only few instructions without loop.
Without the patch, unnecessary loop-carried dependency is introduced by SROA and the loop cannot be eliminated by the later optimizers.

With PGO information, we can do more aggressive outlining of cold regions in the inline candidate function. This contrasts with the scheme of keeping only the 'early return' portion of the inline candidate and outlining the rest of the function as a single function call.
