New Revision: 367659
URL: http://llvm.org/viewvc/llvm-project?rev=367659&view=rev
Log:
Moves the newly added test interleaved-accesses-waw-dependency.ll to X86 subdirectory.
ps4-buildslave1 reported a failure. The test has x86 triple.
Added:

-; The loop does the following operation 3 times:
-; 1. Load x from memory;
-; 2. Store (x + 1) to this memory;
-; 3. if (x < 1), store 0 to this memory.
-
-; When scalar version stores 0 in all locations, the vector version should do
-; the same thing. However, with interleaving it does not honour the WAW dependency between
-; store 0 and store (x + 1) to the same memory.
-; For now, we identify such unsafe dependency and disable adding the
-; store into the interleaved group.
-; In this test case, because we disable adding store into i32* %storeaddr12 and
-; storeaddr22, we create interleaved groups with gaps and
-; disable that interleaved group. So, we are only left with valid interleaved
-; groups.
