sparc.c (INIT_TARGET_OPTABS): If ARCH64, set the 32-bit ABI libfuncs to NULL.
2002-06-24 David S. Miller <davem@redhat.com>
* config/sparc/sparc.c (INIT_TARGET_OPTABS): If ARCH64, set the
32-bit ABI libfuncs to NULL.
* expmed.c (expand_divmod): Do not set optab1/optab2 to the shift
optabs if op1 is const0_rtx.
