Allow subclassing ExternalAA This allows testing AMDGPU alias analysis like any other alias analysis pass. This fixes the existing test pointlessly running opt -O3 when it really just wants to run the one analysis. Before there was no way to test this using -aa-eval with opt, since the default constructed pass is run. The wrapper subclass allows the default constructor to pass the necessary callback. llvm-svn: 346353

[AMDGPU] Add AMDGPUAliasAnalysis to opt pipeline Previously it was added only to the BE. Differential Revision: https://reviews.llvm.org/D31323 llvm-svn: 298721

AMDGPU: fix existing alias rules for constant and global Constant and global may alias, also one rules table wasn't ordered correctly. Pinpointed by Matt. v2: add a test with swapped parameters llvm-svn: 340416

AMDGPU: bump AS.MAX_COMMON_ADDRESS to 6 since 32-bit addr space 32-bit constant address space is declared as 6, so the maximum number of address spaces is 6, not 5. Fixes "LLVM ERROR: Pointer address space out of range". v5: rename MAX_COMMON_ADDRESS to MAX_AMDGPU_ADDRESS v4: - fix compilation issues - fix out of bounds access v3: use static_assert() v2: add a very simple test for 32-bit addr space Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106630 llvm-svn: 340417

AMDGPU: Don't error on out of bounds address spaces We should never abort on valid IR. The most reasonable interpretation of an arbitrary address space pointer is probably some kind of special subset of global memory. llvm-svn: 341894
