We want to find a better way to implement array offset calculation.
The old pattern for an int array member loading is:
and x4, x3, #0xffffffff
lsl x4, x4, #2
add x4, x4, #0x10
ldr x0, [x2, x4]
And the optimized pattern is:
add x1, x2, w3, uxtw #2
ldr x0, [x1, oracle#16]
Here is a jmh unit test for int array member loading:
private final int func(int[] arr) {
int ret = 0;
for (int i=0; i < field0; i++) {
ret += arr[i];
}
return ret;
}
And the jmh performance results:
without this patch with this patch units
1173501.595 948290.420 us/op
Here are the additional issues fixed related to this patch:
1. Fix an issue in MatchProcessor, so that we can process platform specific node
as a matchable node.
2. Close this optimization for substratevm because the derived reference is not
supported yet in SVM.
mx bootstrap passes.
mx gate -o -t 'CTW:hosted' passes.
