That sounds great - it was one bug I was struggling with.
I can turn around a complete test for AVR on mingw and Debian as soon as are
ready.

Please look at PR35860. I believe this is same problem noted here.
subreg-lowering triggering the regression due to worsened conflicts.

IRA does not handle this either with -fno-split-wide-types. Left is IRA as-is
with -O2 -fomit-frame-pointer. Right is same options + -fno-split-wide-types.
.file "t.c" .file "t

Whoops, you have to use to -fno-split-wide-types, not -fno-wide-types. Sorry.
