hubert.reinterpretcast added inline comments.
================
Comment at: llvm/lib/MC/XCOFFObjectWriter.cpp:442
+ // There could be gap (but no zero paddings) between each sections.
+ const MCSectionXCOFF *MCSec = (*Section->Groups[0])[0].MCCsect;
----------------
Suggestion:
There could be a gap (without corresponding zero padding) between sections.
================
Comment at: llvm/lib/MC/XCOFFObjectWriter.cpp:444
+ const MCSectionXCOFF *MCSec = (*Section->Groups[0])[0].MCCsect;
+ CurrentAddressLocation = alignTo(CurrentAddressLocation, MCSec->getAlignment());;
assert(CurrentAddressLocation == Section->Address &&
----------------
I think the assert should check that this value is equal to `Section->Address` without updating `CurrentAddessLocation`. `CurrentAddressLocation` can then be updated to `Section->Address` after the assert.
