[PATCH] D38170: [ELF] - Drop SHF_LINK_ORDER flag from output.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added inline comments.


================
Comment at: ELF/InputSection.cpp:97-98
+  if (!isa<InputSection>(Sec)) {
+    error("Merge and .eh_frame sections are not supported with "
+      "SHF_LINK_ORDER " + toString(Sec));
+    return nullptr;
----------------
  "a section with SHF_LINK_ORDER should not refer a non-regular section: " + toString(Sec)


================
Comment at: ELF/InputSection.h:185
 
+  InputSection *LinkOrderSection = nullptr;
+
----------------
As always, it needs a comment.


================
Comment at: ELF/OutputSections.cpp:447
 
+static uint32_t getLinkOrder(ArrayRef<InputSection *> V) {
+  for (InputSection *IS : V)
----------------
This is O(N^2) where N is the number of input sections. Please don't do that.
