SelectionDAG: Make sure stores are always added to the LegalizedNodes list When truncated vector stores were being custom lowered in VectorLegalizer::LegalizeOp(), the old (illegal) and new (legal) node pair was not being added to LegalizedNodes list. Instead of the legalized result being passed to VectorLegalizer::TranslateLegalizeResult(), the result was being passed back into VectorLegalizer::LegalizeOp(), which ended up adding a (new, new) pair to the list instead. This was causing an assertion failure when a custom lowered truncated vector store was the last instruction a basic block and the VectorLegalizer was unable to find it in the LegalizedNodes list when updating the DAG root. llvm-svn: 188953

; This tests for a bug in the SelectionDAG where custom lowered truncated
; vector stores at the end of a basic block were not being added to the

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444
