When I use `-fproc-alignment=64` to get more comparable benchmark results in [`unordered-containers`](https://github.com/haskell-unordered-containers/unordered-containers), `ld.gold` emits several warnings that make me wonder whether code layout issues are mitigated effectively or not: ``` $ cabal bench ... /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/Data/HashMap/Internal.dyn_o: section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/Data/HashMap/Internal/Array.dyn_o: section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/Data/HashMap/Internal/Strict.dyn_o: section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/Data/HashSet/Internal.dyn_o: section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved ... /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/b/benchmarks/build/benchmarks/benchmarks-tmp/Main.o: section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/libHSunordered-containers-0.2.15.0-inplace.a(Internal.o): section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/libHSunordered-containers-0.2.15.0-inplace.a(Array.o): section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved /usr/bin/ld.gold: warning: /home/simon/src/unordered-containers/dist-newstyle/build/x86_64-linux/ghc-9.0.1/unordered-containers-0.2.15.0/build/libHSunordered-containers-0.2.15.0-inplace.a(Strict.o): section .rodata.str contains incorrectly aligned strings; the alignment of those strings won't be preserved ``` I was hoping that the [user's guide](https://ghc.gitlab.haskell.org/ghc/doc/users_guide/debugging.html#ghc-flag--fproc-alignment) would help me assess these warnings, but it doesn't.
