While fiddling around with the VIS intrinsic builtins I noticed that
none of them have TREE_READONLY set, so the resulting code can be
terrible.
We can't currently do this for alignaddr and faligndata because we
don't model the way those instructions use the %gsr register.
Committed to trunk.
gcc/
* config/sparc/sparc.c (def_builtin): Change from macro into function.
(def_builtin_const): New.
(sparc_vis_init_builtins): Use def_builtin_const for all VIS builtins
other than alignaddr and falignaddr.
