Can you, instead of
/* Copied from va-pa.h, but we probably don't need to align to
word size, since we generate and preserve that invariant. */
u = size_int (size > 4 ? -8 : -4);
t = fold_convert (sizetype, t);
t = build2 (BIT_AND_EXPR, sizetype, t, u);
t = fold_convert (valist_type, t);
use
u = build_int_cst (TREE_TYPE (t), (HOST_WIDE_INT)(size > 4 ? -8 : -4));
t = build2 (BIT_AND_EXPR, TREE_TYPE (t), t, u);
t = fold_convert (valist_type, t);
thus, perform the AND in pointer types? This is what I am going to do
to replace REALIGN_INDIRECT_REF with and teach PTA about this (so to not
pessimize hppa here).
Mine for now - I'll ping you when infrastructure is ready to deal with
pointer BIT_AND_EXPRs.
