--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- At one point -flax-vector-conversions was default and did the option did not exist. https://gcc.gnu.org/ml/gcc/2006-10/msg00682.html See also: https://gcc.gnu.org/ml/gcc/2006-11/msg00051.html NOTE having this option on is required to be complaint with both the Altivec and SPU PEMs. I remember when this discussion was happening since I was working on PowerPC and I even voted against having an option to allowing the lax conversion part.
