; 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!
