* Enable FeatureFlatForGlobal on Volcanic IslandsMatt Arsenault2017-01-241-1/+1
| | | | | | | | | | | This switches to the workaround that HSA defaults to for the mesa path. This should be applied to the 4.0 branch. Patch by Vedran Miletić <vedran@miletic.net> llvm-svn: 292982

| | | | | | This reverts commit r285939 and r285948. These broke some conformance tests. llvm-svn: 285995

* AMDGPU: Improve load/store of illegal types.Matt Arsenault2016-07-011-2/+1
| | | | | | | | | | There was a combine before to handle the simple copy case. Split this into handling loads and stores separately. We might want to change how this handles some of the vector extloads, since this can result in large code size increases. llvm-svn: 274394
* DAGCombiner: Turn truncate of a bitcasted vector to an extractMatt Arsenault2016-03-011-0/+93
On AMDGPU where operations i64 operations are often bitcasted to v2i32 and back, this pattern shows up regularly where it breaks some expected combines on i64, such as load width reducing. This fixes some test failures in a future commit when i64 loads are changed to promote. llvm-svn: 262397
