Backport from mainline:
2008-06-12 Eric Botcazou <ebotcazou@adacore.com>
* expr.c (store_field): Do a block copy from BLKmode to BLKmode-like.
(get_inner_reference): Use BLKmode for byte-aligned BLKmode bitfields.
Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu. OK
for branch?
Thanks,
Uros.
