2017-05-10Build Cheri_embed_types.thy together with Cheri_embed_sequential.thyThomas Bauereiss
2017-05-08add make rules to (attempt to) build arm and power ml.Robert Norton
2017-05-08add some missing things in sail_values and make big_int version the default ↵Robert Norton
for set_vector_subrange_bit.
2017-05-08add error messages for unhandled pattern match nodes in ocaml pretty printer.Robert Norton
2017-05-08put failwith in brackets to avoid parse error.Robert Norton

2017-04-27add command line argument for setting undef values to all zero or all one. ↵Robert Norton
Some tests intentionally produce undefined values (e.g. divide by zero) and this might be required for them to work.
2017-04-25optimise to_vec_int because it is used by MEMr to convert each byte to vector.Robert Norton
2017-04-25replace memory representation with map of 1MB pages rather than map of ↵Robert Norton
bytes. This makes loading binaries much quicker but doesn't seem to make a big difference to execution speed.
2017-04-25remove unused function.Robert Norton
2017-04-25Add support for uart terminal. Also add read_bit_reg function for faster and ↵Robert Norton
neater access to registers of single bit.
2017-04-24added register_value_for_regShaked Flur
2017-04-21it turns out zarith has a function for printing big_ints in hex. Remove the ↵Robert Norton
dependency on ocaml uint library by using it.
2017-04-21define some big_int literals in sail_values.ml to avoid lots of calls to ↵Robert Norton
bit_int_of_int. Likely very little performance benefit but slightly more readable.
2017-04-21Revert change to check in type_check.ml.Alasdair Armstrong
2017-04-21Fixes stack overflow in sail caused by list append in type_internal.ml.Alasdair Armstrong
Also makes the check function in type_check tail recursive.
2017-04-21implement to_vec_big using zarith extract for some speedup.Robert Norton
2017-04-21suppress register field tracing if not enabled (missed in previous commit)Robert Norton
2017-04-21add make variable for setting ocaml compilation options (e.g. set to -p to ↵Robert Norton
enable gprof profiling)
2017-04-20more library optimisation. Implement int_of_bit_array using shift, avoiding ↵Robert Norton
need to use power.
2017-04-20implement vector subrange using Array.sub for approx 10% speedup.Robert Norton
2017-04-20remove unnecessary lemlib include in compile.Robert Norton
2017-04-20add support for cheri128 ocaml shallow embeddingRobert Norton
2017-04-20add brackets around integer literals so that ocaml parses them correctly and ↵Robert Norton
doesn't mistake the - for minus operator
2017-04-20build a single run_embed.native with mips and cheri models linked and choose ↵Robert Norton
between them using a command line switch.
2017-04-20attempt to optimise performance if not tracing writes.Robert Norton
2017-04-20add missing min and max functions, overriding built-in ocaml ones. Also ↵Robert Norton
neq_range.
2017-04-20add missing KD_nabbrev support in ocaml shallow embedding.Robert Norton
2017-04-20support assert in ocaml shallow embedding.Robert Norton
2017-04-20use mangled field name when accessing record field.Robert Norton
2017-04-20add name to register representation and print it on write.Robert Norton
2017-04-18make ocaml embedding of foreach use (now universal) big_ints.Robert Norton
2017-04-18fix definition of mask -- Vregister and VvectorR were swapped.Robert Norton
2017-04-18Implement return using an exception caught in the function body. Polymorphic ↵Robert Norton
exceptions are not permitted so a local mutable variable, ret, is used in ocaml to store the return value. This avoids having to define a new exception type for each function. Ocaml infers the type of the option when it is assigned at the return site.
2017-04-18Generate runtime error for L_undef. Existing code was broken except for type ↵Robert Norton
bit (specifically it caused generated ocaml to fail to type check for an undef number.
2017-04-18added transactional memory supportShaked Flur
2017-04-07fix error in generated ocaml where writing single bit of register was not ↵Robert Norton
taking account of register direction.
2017-04-07implement quot and mod with truncation towards zero which is not the ocaml ↵Robert Norton
way but standard for C and most hw.
2017-04-07simplify xor using ocaml <> operator which also has the advantage of being ↵Robert Norton
more correct
2017-04-06use set_register when writing element of vector of registers to avoid ↵Robert Norton
accidentally replacing Vregister with Vvalue or Vregister... Seems to work for MIPS but not sure if might encounter vector of something other than bit or register. A more specific value type would have made this a compile-time error rather than run-time.
2017-04-06add support for address translation and exit handling in mips ocaml shallow ↵Robert Norton
embedding test setup.
2017-04-06minor changes in sail_values.ml to aid debuggingRobert Norton
2017-04-06fix incorrect use of == in eqRobert Norton
2017-04-06implement exts and extz as manipulations on bit vectors rather than ↵Robert Norton
converting to integers, allowing them to work on vectors containing undef.
2017-04-06Implement exit by raising Sail_exit exceptionRobert Norton
2017-04-03Rename TranslateAddress to TranslatePC and remove the accessType argument -- ↵Robert Norton
it is only ever used for translating the PC.
2017-03-30Make length function return big_intRobert Norton
2017-03-29change reqiured to work with little endian interpreter.Robert Norton
2017-03-29Factor out pretty printers into separate files. Hopefully this will make ↵Robert Norton
searching easier.
2017-03-28temporary fix for problem duplicate (lack of direction) -- assume decreasing ↵Robert Norton
for mips compatibility.
