================
Comment at: llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp:263-308
+ // 16-bit platforms like MSP430 and AVR take this path, so sink this
+ // assert to platforms that use it.
+ auto GetPointerSize = [this]() {
+ unsigned PointerSize = Asm->getDataLayout().getPointerSize();
+ assert((PointerSize == 4 || PointerSize == 8) &&
+ "Add support for other sizes if necessary");
+ return PointerSize;
----------------
Maybe like this? (open to better naming)
================
Comment at: llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp:265-270
+ auto GetPointerSize = [this]() {
+ unsigned PointerSize = Asm->getDataLayout().getPointerSize();
+ assert((PointerSize == 4 || PointerSize == 8) &&
+ "Add support for other sizes if necessary");
+ return PointerSize;
+ };
----------------
Could this instead be "GetPointerSizedForm" and encapsulate the `PointerSize == 4 ? dwarf::DW_OP_const4u : dwarf::DW_OP_const8u` logic too?
Oh, I see there's both OP and FORM needed, not just FORM... maybe still nice to share?
