re PR c/87691 (transparent_union attribute does not work with MODE_PARTIAL_INT)
2018-11-07 Jozef Lawrynowicz <jozef.l@mittosystems.com>
PR c/87691
gcc/ChangeLog:
* stor-layout.c (compute_record_mode): Set TYPE_MODE of UNION_TYPE
to the mode of the widest field iff the widest field has mode class
MODE_INT, or MODE_PARTIAL_INT and the union would be passed by
reference.
gcc/testsuite/ChangeLog:
* gcc.target/msp430/pr87691.c: New test.
