| 2017-06-14 | Add a work-in-progress version of sail_values.lem | Brian Campbell | |
| that uses the new Lem machine words library. | |||
| 2017-06-05 | Attempt to make Lem-prettyprinting of function clauses more robust | Thomas Bauereiss | |
| Instead of abusing patterns as expressions, bind patterns to names (if they are more complex than an identifier or literal and don't have a name already) and generate expressions referring to those names (which we then pass as arguments to the auxiliary functions). | |||
| 2017-06-05 | Fix pretty-printing of function clauses with wildcards for Lem | Thomas Bauereiss | |
| Before, wildcards sometimes ended up in the arguments to the function call on the RHS, in particular when using vector patterns (which implicitly introduce wildcards for the order and index parameters). | |||
| 2017-06-02 | Add tag memory to Lem shallow embedding | Thomas Bauereiss | |
| 2017-05-28 | fixed exmem | Shaked Flur | |
| 2017-05-26 | fix run_with builds after build_context gained an extra argument. | Robert Norton | |
| 2017-05-24 | fixed missing _tag bits | Shaked Flur | |
| 2017-05-24 | Merge branch 'master' of bitbucket.org:Peter_Sewell/sail | Shaked Flur | |
| # Conflicts: # src/lem_interp/interp.lem # src/lem_interp/interp_inter_imp.lem # src/lem_interp/interp_interface.lem # src/parser.mly # src/pretty_print_lem.ml | |||
| 2017-05-24 | added the exmem effect for AArch64 store-exclusive | Shaked Flur | |
| 2017-05-24 | Change types of MEMr_tag, MEMval_tag and co. so that tag is separate from ↵ | Robert Norton | |
| data and invent rmemt and wmvt effects for them. Extend the interpreter context to include lists of tagged memory read and write functions. The memory model must round down the address to the nearest capability aligned address when reading/writing tags. Remove TAGw which is no longer needed as a result. | |||
| 2017-05-24 | it turns out that Zarith has a divide function which does truncation towards ↵ | Robert Norton | |
| zero but it is not exposed via Bit_int_Z. Use it instead of rolling our own. Also ocaml / and mod already do the right thing. | |||
| 2017-05-10 | Build Cheri_embed_types.thy together with Cheri_embed_sequential.thy | Thomas Bauereiss | |
| 2017-05-08 | add make rules to (attempt to) build arm and power ml. | Robert Norton | |
| 2017-05-08 | add some missing things in sail_values and make big_int version the default ↵ | Robert Norton | |
| for set_vector_subrange_bit. | |||
| 2017-05-08 | add error messages for unhandled pattern match nodes in ocaml pretty printer. | Robert Norton | |
| 2017-05-08 | put failwith in brackets to avoid parse error. | Robert Norton | |
| 2017-05-02 | doc | Peter Sewell | |
| 2017-04-27 | add 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. | |||
| 2017-04-25 | optimise to_vec_int because it is used by MEMr to convert each byte to vector. | Robert Norton | |
| 2017-04-25 | replace 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. | |||
| 2017-04-25 | remove unused function. | Robert Norton | |
| 2017-04-25 | Add support for uart terminal. Also add read_bit_reg function for faster and ↵ | Robert Norton | |
| neater access to registers of single bit. | |||
| 2017-04-24 | added register_value_for_reg | Shaked Flur | |
| 2017-04-21 | it turns out zarith has a function for printing big_ints in hex. Remove the ↵ | Robert Norton | |
| dependency on ocaml uint library by using it. | |||
| 2017-04-21 | define 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. | |||
| 2017-04-21 | Revert change to check in type_check.ml. | Alasdair Armstrong | |
| 2017-04-21 | Fixes stack overflow in sail caused by list append in type_internal.ml. | Alasdair Armstrong | |
| Also makes the check function in type_check tail recursive. | |||
| 2017-04-21 | implement to_vec_big using zarith extract for some speedup. | Robert Norton | |
| 2017-04-21 | suppress register field tracing if not enabled (missed in previous commit) | Robert Norton | |
| 2017-04-21 | add make variable for setting ocaml compilation options (e.g. set to -p to ↵ | Robert Norton | |
| enable gprof profiling) | |||
| 2017-04-20 | more library optimisation. Implement int_of_bit_array using shift, avoiding ↵ | Robert Norton | |
| need to use power. | |||
| 2017-04-20 | implement vector subrange using Array.sub for approx 10% speedup. | Robert Norton | |
| 2017-04-20 | remove unnecessary lemlib include in compile. | Robert Norton | |
| 2017-04-20 | add support for cheri128 ocaml shallow embedding | Robert Norton | |
| 2017-04-20 | add brackets around integer literals so that ocaml parses them correctly and ↵ | Robert Norton | |
| doesn't mistake the - for minus operator | |||
| 2017-04-20 | build a single run_embed.native with mips and cheri models linked and choose ↵ | Robert Norton | |
| between them using a command line switch. | |||
| 2017-04-20 | attempt to optimise performance if not tracing writes. | Robert Norton | |
| 2017-04-20 | add missing min and max functions, overriding built-in ocaml ones. Also ↵ | Robert Norton | |
| neq_range. | |||
| 2017-04-20 | add missing KD_nabbrev support in ocaml shallow embedding. | Robert Norton | |
| 2017-04-20 | support assert in ocaml shallow embedding. | Robert Norton | |
| 2017-04-20 | use mangled field name when accessing record field. | Robert Norton | |
| 2017-04-20 | add name to register representation and print it on write. | Robert Norton | |
| 2017-04-18 | make ocaml embedding of foreach use (now universal) big_ints. | Robert Norton | |
| 2017-04-18 | fix definition of mask -- Vregister and VvectorR were swapped. | Robert Norton | |
| 2017-04-18 | Implement 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. | |||
| 2017-04-18 | Generate 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. | |||
| 2017-04-18 | added transactional memory support | Shaked Flur | |
| 2017-04-07 | fix error in generated ocaml where writing single bit of register was not ↵ | Robert Norton | |
| taking account of register direction. | |||
| 2017-04-07 | implement quot and mod with truncation towards zero which is not the ocaml ↵ | Robert Norton | |
| way but standard for C and most hw. | |||
| 2017-04-07 | simplify xor using ocaml <> operator which also has the advantage of being ↵ | Robert Norton | |
| more correct | |||
