Just for discussion, clang doesn't align the relocs (as they are produced by
ld) - I presume you meant why clang doesn't align the rdata section.

Judging from the linker script, wouldn't it mostly be a case of clang producing
object files with .rdata sections that end with an uneven number of bytes? And
I don't see how that would be suspicious. I haven't dug into a full case of
this happening though.

In any case, the applied patch certainly is right though.

(I'm just arguing because I don't think there is a bug to be fixed on the clang
side wrt this, as someone is led to believe in
https://bugs.llvm.org/show_bug.cgi?id=39754.)
