Fix pointer EVT in SelectionDAGBuilder::visitAlloca SelectionDAGBuilder::visitAlloca assumes alloca address space is 0, which is incorrect for triple amdgcn---amdgiz and causes isel failure. This patch fixes that. Differential Revision: https://reviews.llvm.org/D40095 llvm-svn: 318392

AMDGPU: Produce error on dynamic_stackalloc llvm-svn: 246048

Refactor backend diagnostics for unsupported features Re-commit of r258951 after fixing layering violation. The BPF and WebAssembly backends had identical code for emitting errors for unsupported features, and AMDGPU had very similar code. This merges them all into one DiagnosticInfo subclass, that can be used by any backend. There should be minimal functional changes here, but some AMDGPU tests have been updated for the new format of errors (it used a slightly different format to BPF and WebAssembly). The AMDGPU error messages will now benefit from having precise source locations when debug info is available. llvm-svn: 259498

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
