R600/SI: Initial local memory support Enough for the radeonsi driver to use it for calculating derivatives. Reviewed-by: Tom Stellard <thomas.stellard@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186012 91177308-0d34-0410-b5e6-96231b3b80d8

R600/SI: Use -verify-machineinstrs for most tests We can't enable the verifier for tests with SI_IF and SI_ELSE, because these instructions are always followed by a COPY which copies their result to the next basic block. This violates the machine verifier's rule that non-terminators can not folow terminators.

Allow aliases to be unnamed_addr. Alias with unnamed_addr were in a strange state. It is stored in GlobalValue, the language reference talks about "unnamed_addr aliases" but the verifier was rejecting them. It seems natural to allow unnamed_addr in aliases: * It is a property of how it is accessed, not of the data itself. * It is perfectly possible to write code that depends on the address of an alias. This patch then makes unname_addr legal for aliases. One side effect is that the syntax changes for a corner case: In globals, unnamed_addr is now printed before the address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210302 91177308-0d34-0410-b5e6-96231b3b80d8
