AMDGPU: Enable code object v3 for AMDHSA only Differential Revision: https://reviews.llvm.org/D54186 llvm-svn: 346923

AMDGPU: Fix crash with dispatch.ptr intrinsic with non-HSA target It might be better to let this be a select failure instead. llvm-svn: 257386

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: Rework how private buffer passed for HSA If we know we have stack objects, we reserve the registers that the private buffer resource and wave offset are passed and use them directly. If not, reserve the last 5 SGPRs just in case we need to spill. After register allocation, try to pick the next available registers instead of the last SGPRs, and then insert copies from the inputs to the reserved registers in the progloue. This also only selectively enables all of the input registers which are really required instead of always enabling them. llvm-svn: 254331

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
