+    constexpr auto ABIFlagsSize = sizeof(Elf_Mips_ABIFlags);

We don't even sprinkle `const` that much, but we avoid `auto` as long as its type is obvious by RHS. So please avoid `auto` here.


================
Comment at: ELF/SyntheticSections.cpp:139-143
+    if (Size < ABIFlagsSize) {
+      error(Filename + ": invalid size of .MIPS.abiflags section: got " +
+            Twine(Size) + " instead of " + Twine(ABIFlagsSize));
       return nullptr;
     }
----------------
I think the next `if` covers this case, no? If `Size < ABIFlagsSize`, its modulo is not zero.
