Dan Gohmanf17a25c2007-07-18 16:29:46 +00001; This testcase checks to make sure that the assembler can handle floating
2; point constants in IEEE hex format. This also checks that the disassembler,
3; when presented with a FP constant that cannot be represented exactly in
4; exponential form, outputs it correctly in hex format. This is a distillation
5; of the bug that was causing the Olden Health benchmark to output incorrect
6; results!
