According to our configure checks, this is the list of supported
compilers.

+Supported compilers
+-------------------
+
+To compile, QEMU requires either:
+
+- GCC >= 7.4.0
+- Clang >= 6.0
+- XCode Clang >= 10.0
Do we need to spell out the versions explicitly ? These versions are
all derived from what's available in the repos of the supported build
platforms, similar to any other build deps we have. I don't think we
want to start a precedent of duplicating versions in this doc for
build deps we have, and there's nothing particularly special about
compilers in this respect.
I agree with Daniel - when I saw this patch, the first thought that I had
was: "This will be getting out of sync quickly" ...
I don't have the impression we bump our compiler requirement regularly
or lightly.
"quickly" in the sense of that it will be out of sync once somebody bumps
the version check in the "configure" script - since I doubt that it will be
remembered to update this document here as well.
so I'd also recommend to rather not add this here.
Outdated documentation is still better than no documentation. YMMV.
Well, no. In this case, it might rather create wrong expectations for the
users if they read that their compiler is still supported, but the configure
script refuses it.
Anyway, if you feel like we need more information for the users about
supported systems and compiler versions, feel free to update this page here
instead, it has also fallen behind already quite a bit:
