Hello!
Use can_create_pseudo_p () for things that happen strictly before reload.
2011-05-13 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.md (*movxf_internal): Use !can_create_pseudo ().
(*movxf_internal_nointeger): Ditto.
(*movdf_internal_rex64): Ditto.
(*movdf_internal): Ditto.
(*movdf_internal_nointeger): Ditto.
(*movsf_internal): Ditto.
(sincos splitters): Use can_create_pseudo ().
Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN.
Uros.
