Hi, I'm stumped by how to handle fpowi. Here is the context: my architecture has i64, f32, and f64 registers. No i32. For calls & returns, we promote i32 to i64. There is no support in the architecture to perform fpowi - it has to go through the runtime. I'm using gfortran + dragonegg + llvm3.4 to generate .ll files via plugin. The fortran expression REAL = REAL ** INTEGER*4

Hey all, I am trying to implement a subtarget for the X86 architecture that only has 64 bit Registers. While running LLC on the IR for a very simple program, llc fails on an assertion that says it doesn't know how to promote ISD::FRAMEINDEX. I've tried to look for why how to promote the frameindex which is stored in a i32 variable to an i64 variable but can't seem to find where
