GaloisInc/saw-script

• Released under the 3-clause BSD license
• Major improvements to the Java and LLVM verification infrastructure,
  as described in more detail here:
  • Major refactoring and polish to java_verify and java_symexec
  • Major refactoring and polish to llvm_verify and llvm_symexec
  • Fixed soundness bug in llvm_verify treatment of heap
    modifications
  • Fixed soundness bug related to java_assert and llvm_assert
  • Support for branch satisfiability checking to be configured
  • Support for some types of allocation in java_verify, enabled
    with java_allow_alloc
  • Improved support for LLVM structs (including the llvm_struct
    type for llvm_verify)
  • Support for non-scalar return values in java_verify and
    java_symexec
  • Support for using java_ensure_eq on fields of return value
  • Access to safety conditions in java_symexec and llvm_symexec
  • New primitives llvm_assert_eq and java_assert_eq
• Some changes to the SAWScript language:
  • Conditional expressions including the keywords if, then, and
    else, and the new constants true and false
  • New eval_int and eval_bool functions to expose Cryptol bit
    vectors and Bit values as Int and Bool values in SAWScript
  • Pattern matching for tuples
  • Improvements to pretty printing, including: set_base and
    set_ascii commands to control the formatting of values; a show
    function to convert a value to a string without printing it; and
    the ability to use print or show instead of
    llvm_browse_module and java_browse_class
  • New built-in functions for processing lists
• New proof backends:
  • A new rme proof tactic, based on the
    Reed-Muller Expansion
    normal form for propositional formulas. This tactic is
    particularly efficient for dealing with polynomials over Galois
    fields, as used in AES, for instance.
• Linked against the latest Cryptol code, which includes the following
  changes since release 2.3.0:
  • An extended prelude with more Haskell-like functions
  • Better, more portable seeding for random
  • Performance improvements for symbolically executing tables of
    constant values
  • Performance improvements for type checking large constants
• Internal improvements:
  • Simplified Cryptol to SAWCore translation
  • Improved performance of Cryptol to SAWCore translation for
    recursive functions
  • Updated bitcode parser to support some of the changes in LLVM 3.7
  • Many bug fixes
  • Many code cleanups
