Floating-point changes. `fpX_to_value` is defined as `float_to_value o fpX_to_float` (previously this was called `fpX_to_real`, which was misleading) `fpX_to_real` is now defined as `float_to_real o fpX_to_float`. This change will break proofs that use the old names.

Add some more float-to-float functions to machine_ieeeTheory. Also add versions that output flags for the exception status.

Update floating-point theory to specify exception flags for some operations. • The flags are: DivideByZero, InvalidOp, Overflow, Precision and Underflow. • The arithmetic operations now return a pair (flags and result). • Native (oracle) evaluation has been overhauled. It now only applies to some 64-bit machine_ieeeTheory operations directly. • The L3 Importer has been updated.

Floating-point update. • isSignallingNan predicate is added to machine_ieeeTheory. • The RISC-V model is simplified in places (for DIV and REM). • The L3 import is extended to cover more operations.

Remove float_negate1985 and float_abs1985 This seems to have been half done in 086cbeb857ffbcc88784f4f81db7626771ad8758

Anthony Fox <anthony.fox@cl.cam.ac.uk> |
Update for the latest version of L3, which has additional floating-point support. Cover IEEE754:1985 behaviour for "abs" and "neg". Also adds support for "compare", "toInt" and "fromInt" at the machine level.
