FWIW I have massaged the VAX backend sufficiently for the `vax-netbsdelf' target to successfully build with `-mlra' as the default. There are still several ICE regressions throughout the testsuite however (none for old reload), to say nothing about severe code quality regression where it does build. So there seems to be a lot of work to do there yet even if we let code quality regress with LRA. I plan to do it, but it won't be quick. Maciej
