gcc/
* doc/tm.texi (CLZ_DEFINED_VALUE_AT_ZERO, CTZ_DEFINED_VALUE_AT_ZERO):
Document change in interpretation of value from boolean to
tri-state integer.
* optabs.c (expand_ffs, expand_ctz): New functions to compute
ffs and ctz using clz.
(expand_unop): Call them.
* config/rs6000/rs6000.h (CLZ_DEFINED_VALUE_AT_ZERO): Fix its
result value.
(CTZ_DEFINED_VALUE_AT_ZERO): Likewise.
* config/mips/mips.h (CLZ_DEFINED_VALUE_AT_ZERO): Likewise, to
enable the new ffs expansion on this target.
