| 2018-07-09 | Initialize fresh memory to 0 in the OCaml backend. | Prashanth Mundkur | |
| This makes it consistent with the C backend, and also makes it easier to compare traces across execution re-runs. | |||
| 2018-06-22 | add support for new cycle_limit feature in mips. | Robert Norton | |
| 2018-06-21 | Merge branch 'tracing' into sail2 | Alasdair Armstrong | |

| 2018-06-11 | Merge branch 'sail2' into mappings | Jon French | |
| (involved some manual tinkering with gitignore, type_check, riscv) | |||
| 2018-06-04 | switch to using a Map data structure for cheri tags in ocaml backend. This ↵ | Robert Norton | |
| solves a problem where the Hashtbl module was encountering a stack overflow booting CheriBSD. There seems to be little or no performance impact. | |||
| 2018-06-04 | Use Util.split_on_char in sail_lib.ml | Alasdair Armstrong | |
| 2018-05-31 | Fix for Jenkins build | Alasdair Armstrong | |
| Looks like Jenkins is still on OCaml 4.02.3. We should probably upgrade to 4.05 at some point. | |||
| 2018-05-31 | Fixes to get ARM u-boot working in Sail. | Alasdair Armstrong | |
| Also fixes to C backend for compiling MIPS spec to C - Fix an issue with const correctness in internal_vector_update functions generated by C backend - Add builtins for MIPS to sail.h - Fix an issue where reg_deref didn't work when called on pointers to large bitvectors, i.e. vectors containing references to large bitfields as in the MIPS TLB code - Various bug fixes and changes for running U-boot on ARM model, including for interpreter and OCaml compilation. - Fix memory leak issues and incorrect shadowing for foreach loops - Update C header file. Fixes memory leak in memory read/write builtins. - Add aux constructor to ANF representation to hold environment information. - Fix undefined behavior caused by optimisation left shifting uint64_t vectors 64 or more times. Unfortunately there's more issues because the same happens for X >> 64 right shifts. It would make sense for this to be zero, because that would guarantee the property that ((X >> n) >> m) == (X >> (n + m)) but we probably need to do (X >> (n - 1) >> 1) in the optimisation to ensure that we don't cause UB. Shifting by 63 and then by 1 is well-defined, but shifting by 64 in one go isn't according to the C standard. This issue with right-shifts only occurs for zero-length vectors, so it's not a huge deal, but it's still annoying. - Add versions of print_bits and print_int that print to stderr. Follows OCaml convention of print/prerr. Should make things more explicit. Different backends had different ideas about where print should output to, not every backend needs to have this (e.g. theorem prover backends don't need to print) but having both stderr and stdout seperate and clear is useful for executable models (UART needs to be stdout, debug messages should be stderr). | |||
| 2018-05-31 | Some tweaks to ocaml compilation and sail_lib for ARM with system registers | Alasdair Armstrong | |
| 2018-05-25 | Use paged memory storage for ocaml backend memory. This is slightly slower ↵ | Robert Norton | |
| (<5% on a simple test) but dramatically reduces memory usage compared to having a hash table entry per byte! | |||

| 2018-05-21 | further RISCV mapping: all extant non-compressed instructions done | Jon French | |

| 2018-03-12 | ELF loading for C backend | Alasdair Armstrong | |
| Add a flag to Sail that allows for an image of an elf file to be dumped in a simple format using linksem, used as sail -elf test.elf -o test.bin This image file can then be used by a compiled C version of a sail spec as with ocaml simply by ./a.out test.bin | |||
