SjoerdMeijer added inline comments.
================
Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:8111
"pointer cannot be cast to type %0">;
+def err_cast_to_bfloat : Error<"cannot type-cast to __bf16">;
+def err_cast_from_bfloat : Error<"cannot type-cast from __bf16">;
----------------
Nit: was wondering if `err_cast_to_bfloat16` would be more consistent
================
Comment at: clang/lib/AST/ASTContext.cpp:6007
case Float16Rank:
case HalfRank: llvm_unreachable("Complex half is not supported");
case FloatRank: return FloatComplexTy;
----------------
nit: perhaps this error message is not entirely accurate for bfloat16?
================
Comment at: clang/lib/Basic/Targets/AArch64.cpp:74
+ BFloat16Width = BFloat16Align = 16;
+ BFloat16Format = &llvm::APFloat::BFloat();
+
----------------
Nit: we use bfloat16 everywhere, would `llvm::APFloat::BFloat16()` be better
for consistency?
================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:115
HalfTy = llvm::Type::getHalfTy(LLVMContext);
+ BFloatTy = llvm::Type::getBFloatTy(LLVMContext);
FloatTy = llvm::Type::getFloatTy(LLVMContext);
----------------
nit: perhaps `getBFloat16Ty()`
================
Comment at: clang/lib/CodeGen/CodeGenTypeCache.h:39
+ /// half, bfloat, float, double
+ llvm::Type *HalfTy, *BFloatTy, *FloatTy, *DoubleTy;
----------------
And so here too, BFloat16Ty?
================
Comment at: clang/lib/CodeGen/TargetInfo.cpp:5844
ABIKind Kind;
+ bool IsSoftFloatABI;
----------------
Nit: to distinguish the unfortunate float ABI names, I was wondering whether
`IsFloatABISoftFP` is clearer, or something along those lines, just to make
clear it is not the "soft" but the "softfp" variant
