> Richard, could you please have a look?
I don't have access to sparc-sun-solaris2*, so I can't bootstrap it (but
at most build a cross cc1).
So please attach a testcase (easiest is probably in a non-bootstrapped
tree run make check and pick a simple one that fails from the C testsuite).
Is sparc-sun-solaris2* a STRICT_ALIGNMENT target? What's the clr instruction?
Is it a store or a load?
The revision in question is supposed to make alignment less strict and I
can't see how this can break anything.
