; This testcase checks to make sure that the assembler can handle floating
; point constants in IEEE hex format. This also checks that the disassembler,
; when presented with a FP constant that cannot be represented exactly in
; exponential form, outputs it correctly in hex format. This is a distillation
; of the bug that was causing the Olden Health benchmark to output incorrect
; results!
