I've included the patch in nightly bootstraps on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and i686-pc-linux-gnu. All completed without
regressions, thanks.
One last issue, though. The error messages totally feel like line noise
to me:
/vol/gcc/src/hg/trunk/local/gcc/tree-ssa-forwprop.c: In function 'bool
simplify_rotate(gimple_stmt_iterator*)':
/vol/gcc/src/hg/trunk/local/gcc/tree-ssa-forwprop.c:1650:40: error:
'#'target_mem_ref' not supported by dump_expr#<expression error>' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
1650 | if (cdef_arg2[i] == def_arg2[1 - i]
| ~~~~~~~~~~~~~~^
Is this really something we mean to expose to users?
