From 4715081787d4c3f1e2fa4b8d23b484b5b5d437bb Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Thu, 11 Jul 2013 17:43:32 +0000 Subject: PPC: Add some missing V_SET0 patterns We had patterns to match v4i32 immAllZerosV -> V_SET0, but not patterns for v8i16 (which occurs in the test case) or v16i8. The same was true for V_SETALLONES (so I added the associated patterns for those as well).
