Hello!
The mode of address_operand predicate is ignored in ix86_legitimate_address_p.
2012-08-13 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.md (prefetch): Do not assert mode of operand 0.
(*prefetch_sse_<mode>): Do not set mode of address_operand predicate.
Rename to ...
(*prefetch_sse): ... this.
(*prefetch_3dnow_<mode>): Do not set mode of address_operand predicate.
Rename to ...
(*prefetch_3dnow): ... this.
Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32} and
committed to mainline SVN.
Uros.
