simplify-rtx.c (mode_signbit_p): Externalize function...
2004-10-18 Pat Haugen <pthaugen@us.ibm.com>
* simplify-rtx.c (mode_signbit_p): Externalize function...
* rtl.h (mode_signbit_p): ... to here.
* combine.c (simplify_shift_const): Recognize PLUS signbit as
canonical form of XOR signbit and move to outer op.
