|
+This patch implements a fast case for the stelem.ref opcode in managed
|
|
+code. If the quick test fails, the code falls back on to managed code.
|
|
+
|
|
+This gave me a nice 3% boost in MCS.
|
|
+
|
|
+I was able to do a full bootstrap with this patch. I also added some
|
|
+regression tests (in the patch) which passed.
