[PATCH] D77557: [DWARFDebugLine] Use truncating data extractors for prologue parsing

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: llvm/unittests/DebugInfo/DWARF/DWARFDebugLineTest.cpp:457
 
-  uint64_t ExpectedEnd =
-      Prologue.TotalLength - 2 + Prologue.sizeofTotalLength();
+  uint64_t ExpectedEnd = Prologue.TotalLength + Prologue.sizeofTotalLength() -
+                         (Version != 5 ? 2 : 8);
----------------
At a first glance, 2 : 8 looks a bit magical. This may deserve a comment.
