PR target/10979
* config/i386/i386.md (atan2df3, atan2sf3, atan2xf3, atan2tf3): Changed to define_expand patterns that copy operand[1] to prevent it from being clobbered before emitting an atan2?f3_1 insn. (atan2df3_1, atan2sf3_1, atan2xf_1, atan2tf3_1): New define_insn patterns that actually specify the behaviour of x87's FPATAN. * gcc.dg/20030707-1.c: New testcase. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@69060 138bc75d-0d04-0410-961f-82ee72b054a4
