A related but different test case.
Attached is another test case that tweaks a similar bug that Pat's test case
exposes. In this case, it is not dependent on Mike's patch. The problem for
both starts in rs6000_expand_vector_init(). In Pat's test case, we attempt to
load the same constant into each V2DFmode half, with this test case, we attempt
to load different values, one being a constant and the other a var which leads
to a different ICE:
pr48053-2.c: In function âfooâ:
pr48053-2.c:29:14: internal compiler error: in int_mode_for_mode, at
stor-layout.c:490
