Seems fine with the adjustments.
================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:3714
Subtarget->ClassifyGlobalReference(GV, getTargetMachine());
+ EVT PtrVT = getPointerTy(DAG.getDataLayout());
+ SDValue Result;
----------------
Can you lower this to ~L3725.
================
Comment at: lib/Target/AArch64/AArch64MCInstLower.cpp:41
+ const Triple &TheTriple = Printer.TM.getTargetTriple();
+ if (TheTriple.isOSBinFormatCOFF()) {
+ assert(TheTriple.isOSWindows() &&
----------------
Early return please:
if (!TheTriple.isOSBinFormatCOFF())
return Printer.getSymbol(MO.getGlobal());
...
================
Comment at: test/CodeGen/AArch64/dllimport.ll:1
+; RUN: llc -mtriple aarch64-windows -filetype asm -o - %s | FileCheck %s
+
----------------
I prefer the canonicalized triple `aarch64-unknown-windows-msvc`
================
Comment at: test/CodeGen/AArch64/dllimport.ll:6
+declare dllimport arm_aapcs_vfpcc i32 @external()
+declare arm_aapcs_vfpcc i32 @internal()
+
----------------
Are the `arm_aapcs_vfpcc` correct here? The variant of AAPCS64 isn't marked differently I thought. The same through out.
