Add AccessibleObject and Field to mirror
Main motivation is to remove all the functionality / field access on
java side to ArtField. Also comes with some reflection speedups /
slowdowns.
Summary results:
getDeclaredField/getField are slower mostly due to JNI overhead.
However, there is a large speedup in getInt, setInt,
GetInstanceField, and GetStaticField.
Before timings (N5 --compiler-filter=everything):
benchmark ns linear runtime
Class_getDeclaredField 782.86 ===
Class_getField 832.77 ===
Field_getInt 160.17 =
Field_setInt 195.88 =
GetInstanceField 3214.38 ==============
GetStaticField 6809.49 ==============================
After:
Class_getDeclaredField 1068.15 ============
Class_getField 1180.00 ==============
Field_getInt 121.85 =
Field_setInt 139.98 =
GetInstanceField 1986.15 =======================
GetStaticField 2523.63 ==============================
