[AMDGPU] Remove exit-on-error in test (PR27761) The exit-on-error flag was necessary in order to avoid an assertion when handling DYNAMIC_STACKALLOC nodes in SelectionDAGLegalize. We can avoid the assertion by creating some dummy nodes. This enables us to remove the exit-on-error flag on the first 2 run lines (SI), but on the third run line (R600) we would run into another assertion when trying to reserve indirect registers. This patch also replaces that assertion with an early exit from the function. Fixes PR27761. Differential Revision: http://reviews.llvm.org/D20852 llvm-svn: 273550

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
