--- Comment #5 from Vladimir Makarov ---
There should be no REG_EQUIV as RTL doc says "it is valid for the compiler to
replace the pseudo-register by stack slot throughout the function". In this
case the substitution results in a wrong code.

PPC64 Linux Altivec and VSX by default while AIX does not. PPC64 Linux loads
0.0 into FPR using VSX xxlor instruction while AIX loads via constant in
memory. This causes the different REG_EQUIV alias set.
