--- Comment #10 from Matt Thompson <matthew.thompson at nasa dot gov> ---
Query from someone who I believe just encountered this trying to build 11.2=
 on
macOS 11.5.1 with XCode 12.5: What is the best method to work around this f=
or
now?=20

1. Update to XCode 12.5.1 (which apparently exists, but I don't know if it =
has
the fixes?)
2. Pass in `--without-build-config` to configure (which is how Homebrew does
it)
3. Iain's last suggestion about `-mllvm -x86-pad-for-align=3Dfalse` (I'm no=
t sure
where to put that)

The easiest for me to try was #2 and it seems to work, but I don't know if =
that
has side-effects for the built compiler.

(Of course, our software currently has some issues with GCC 11.1 that I thi=
nk
are still open here on Bugzilla (like #100651), but I thought I'd see if 11=
.2
fixes them!)=
