Hi all
I didn't find anything relevant in the archives about this so I wanted to
ask here.
I am generating a simple function for JIT using the API. The function
structure and code work fine with 2.8 but give me "Cannot select" with
2.9.
Assembly dump of the function:
define double @0(double %f0, double %f1, double %f2, double %f3, double %f4,
double %f5, double %f6, double %f7, double %f8, double %f9) {
%1 = add double %f0, %f1
%2 = add double %1, %f2
%3 = add double %2, %f3
%4 = add double %3, %f4
%5 = add double %4, %f5
%6 = add double %5, %f6
%7 = add double %6, %f7
%8 = add double %7, %f8
%9 = add double %8, %f9
ret double %9
}
LLVM error I get:

0xd1ab20: i64 = undef [ORD=8] [ID=10]
Is there something different I need to do in my function definition or
structure to get by this? Or is this a bug?
Thanks
