Hello!
Attached patch tightens the condition for TYPE_LEA instructions.
2015-01-26 Uros Bizjak <ubiz...@gmail.com>
PR target/64795
* config/i386/i386.md (*movdi_internal): Also check operand 0
to determine TYPE_LEA operand.
(*movsi_internal): Ditto.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Unfortunately, I was not able to construct a valid testcase, but the
problem is fixed in an obvious way.
Patch was committed to mainline, will be backported to release branches.
Uros.
