+// This is for testing inlining behavior in the jits.
+//
+// For Baseline, run:
+//    $ IONFLAGS=bl-ic .../js --ion-off --baseline-eager inline-access.js
+// Then inspect the output, there should be calls to "GetElem(TypedArray[Int32])",
+// "GetProp(NativeObj/NativeGetter 0x...)", and "SetElem_TypedArray stub"
+// for the read access, length access, and write access respectively, within f.
+//
+// For Ion, run:
+//    $ IONFLAGS=logs .../js --ion-offthread-compile=off inline-access.js
+// Then postprocess with iongraph and verify (by inspecting MIR late in the pipeline)
+// that it contains instructions like "typedarraylength", "loadtypedarrayelement",
+// and "storetypedarrayelement".
