[LLVMdev] floating point exception and SSE2 instructions
Hi,
I'm building a little JIT that creates functions to do array manipulations,
eg. sum all the elements of a double* array. I'm writing this in python, generating
llvm assembly intructions and piping that through a call to ParseAssemblyString,
ExecutionEngine, etc.
It's working OK on integer values, but i'm getting nasty floating point exceptions
when i try this on double*
