re PR target/9732 ([ppc32] Wrong code with -O2 -fPIC)
2003-02-25 Franz Sirl <Franz.Sirl-kernel@lauterbach.com>
PR target/9732
* config/rs6000/rs6000.c (first_reg_to_save): Handle
PIC_OFFSET_TABLE_REGNUM for -fPIC too.
(rs6000_emit_prologue): Likewise.
(rs6000_emit_epilogue): Likewise.
* config/rs6000/rs6000.h (CONDITIONAL_REGISTER_USAGE): Make
PIC_OFFSET_TABLE_REGNUM a fixed register for -fPIC.
