FTBFS with gcc-12.2.0

[cpaelzer]

Hi,
this is not your issue (it is in gcc AFAICS), but I wanted to file it anyway for your awareness as others might look here for a resolution.
Please close/flag this case accordingly, but having it indexed in search engines will help :-)

If you build qemu-palcode with GCC 12.2.0 I've reliably got the following error.

Repro steps in Ubuntu 22.10:

$ git clone https://gitlab.com/qemu-project/qemu-palcode.git
$ cd qemu-palcode/
$ apt install gcc-alpha-linux-gnu
$ make CROSS=alpha-linux-gnu-
...

during RTL pass: expand

make: *** [<builtin>: console.o] Error 1

The real issue I assume is in GCC which is filed here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106966

I realized too late it is just the mirror (working on too many projects exception), I moved it over at least to gitlab (which has more attention) and will send a mail about it afterwards.
Closing this one ...
