craig.topper added inline comments.
================
Comment at: clang/lib/Basic/Targets/AArch64.cpp:69
+ Bfloat16Width = Bfloat16Align = 16;
+ Bfloat16Format = &llvm::APFloat::IEEEhalf();
+
----------------
Doesn't Bfloat16 have a different number of mantissa and exponent bits than
IEEEhalf?
================
Comment at: clang/test/CodeGen/arm-mangle-16bit-float.cpp:4
+
+// CHECK64: define {{.*}}void @_Z3foou6__bf16(half %b)
+// CHECK32: define {{.*}}void @_Z3foou6__bf16(i32 %b.coerce)
----------------
How can bfloat16 be passed as half? Don't they have a different format?
