...ve run into an issue specifying intrinsics for AVX. Right now one can use GCCBuiltin to get automatic CBE (and other) support for emitting intrinsics as gcc builtins. It looks like this: def int_x86_sse3_hadd_pd : GCCBuiltin<"__builtin_ia32_haddpd">, Intrinsic<[llvm_v2f64_ty], [llvm_v2f64_ty, llvm_v2f64_ty], [IntrNoMem]>; AVX has 128-bit instructions that work exactly like SSE instructions except they have non-destructive operands. gcc defines intrinsics for 256-bit operations but does not define special intrinsics for 128-bit AVX instruct...

Is it legal to do something like a !strconcat on a non-string entity? That is, is there some operation that will let me do this (replace SOME_CONCAT with an appropriate operator): (WARNING! Hacked-up tablegen ahead!) multiclass sse_fp_binop_bitwise_rm<bits<8> opc, string OpcodeStr, SDNode OpNode> { // Vector operation emulating scalar (fp)

I have a question about the SSE scalar convert intrinsics. cvtsd2si is defined thusly: def int_x86_sse2_cvtsd2si64 : GCCBuiltin<"__builtin_ia32_cvtsd2si64">, Intrinsic<[llvm_i64_ty, llvm_v2f64_ty], [IntrNoMem]>; This matches the signature of the GCC intrinsic. The fact that the GCC intrinsic has a type mismatch on the input (vector rather than scalar) is strange, but ok, we'll run with it. Until this: def Int_CVTSD2SIrm : SDI<0x2D, MRMSrcMem, (outs GR32:$dst), (ins f128mem: $s...
