[Bug target/34526] no-altivec ABI should be fixed or no longer be the default

--- Comment #5 from janis at gcc dot gnu dot org 2008-02-04 21:28 --- A prerequisite to changing the default to the AltiVec ABI is to fix -mabi=no-altivec. A patch for that is at http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00094.html -- http://gcc.gnu.org/bugzilla

--- Comment #6 from janis at gcc dot gnu dot org 2008-02-05 02:23 --- There's another mess hiding under the ABI change, which is that synthetic vectors of the same size as AltiVec vectors are passed differently for -mabi=altivec than for -mabi=no-altivec. There are warnings
