+`generated_definitions/coq/RV64/riscv.v`, and the HOL4 model in
+`generated_definitions/hol4/RV64/riscvScript.sml`.
+
+One can build either the RV32 or the RV64 model by specifying
+`ARCH=RV32` or `ARCH=RV64` on the `make` line, and using the matching
+target suffix.  RV64 is built by default, but the RV32 model can be
+built using:
 
 ```
-$ ./ocaml_emulator/riscv_ocaml_sim  <elf-file>
-$ ./c_emulator/riscv_sim <elf-file>
+$ ARCH=RV32 make
 ```
-Some information on additional configuration options for each simulator is available
-from `./ocaml_emulator/riscv_ocaml_sim -h` and `./c_emulator/riscv_sim -h`.
 
-Booting Linux with the C backend
---------------------------------
+which creates the 32-bit OCaml simulator in
+`ocaml_emulator/riscv_ocaml_sim_RV32`, and the C simulator in
+`c_emulator/riscv_sim_RV32`, and the prover models in the
+corresponding `RV32` subdirectories.
 
-The C model needs an ELF-version of the BBL (Berkeley-Boot-Loader)
-that contains the Linux kernel as an embedded payload.  It also needs
-a DTB (device-tree blob) file describing the platform (say in the file
-`spike.dtb`).  Once those are available (see below for suggestions),
-the model should be run as:
+The Makefile targets `riscv_isa_build`, `riscv_coq_build`, and
+`riscv_hol_build` invoke the respective prover to process the

+Kananaskis-12.  When building these targets, please make sure the
+corresponding prover libraries in the Sail directory
+(`$SAIL_DIR/lib/$prover`) are up-to-date and built, e.g. by running
+`make` in those directories.
 
-```
-$ ./c_emulator/riscv_sim -t console.log -b spike.dtb bbl > execution-trace.log 2>&1 &
-$ tail -f console.log
-```
-The `console.log` file contains the console boot messages. For maximum
-performance and benchmarking a model without any execution tracing is
-available on the optimize branch (`git checkout optimize`) of this
-repository. This currently requires the latest Sail built from source.
+Executing test binaries
+-----------------------
 
-Booting Linux with the OCaml backend
-------------------------------------
+The C and OCaml simulators can be used to execute small test binaries.
 
-The OCaml model only needs the ELF-version of the BBL, since it can generate its
-own DTB.
 ```
-$ ./ocaml_emulator/riscv_ocaml_sim bbl > execution-trace.log 2> console.log
+$ ./ocaml_emulator/riscv_ocaml_sim_<arch>  <elf-file>
+$ ./c_emulator/riscv_sim_<arch> <elf-file>
 ```
 
-Generating input files for Linux boot
--------------------------------------
+A suite of RV32 and RV64 test programs derived from the
+[`riscv-tests`](https://github.com/riscv/riscv-tests) test-suite is
+included under [test/riscv-tests/](test/riscv-tests/).  The test-suite
+can be run using `test/run_tests.sh`.
 
-One could directly build Linux and the toolchain using
-`https://github.com/sifive/freedom-u-sdk`.  The built `bbl`
-will be available in `./work/riscv-pk/bbl`.  You will need to configure
-a kernel that can be booted on Spike; in particular, it should be
-configured to use the HTIF console.
+Configuring platform options
+----------------------------
 
-The DTB can be generated using Spike and the DeviceTree compiler
-`dtc` as:
+Some information on additional configuration options for each
+simulator is available from `./ocaml_emulator/riscv_ocaml_sim_<arch>
+-h` and `./c_emulator/riscv_sim_<arch> -h`.
 
-```
-spike --dump-dts . | dtc > spike.dtb
-```
-
-(The '.' above is to work around a minor Spike bug and may not be
-needed in future Spike versions.)
-
-Caveats for OS boot
--------------------
+Some useful options are: configuring whether misaligned accesses trap
+(`--enable-misaligned` for C and `-enable-misaligned` for OCaml), and
+whether page-table walks update PTE bits (`--enable-dirty-update` for C
+and `-enable-dirty-update` for OCaml).
 
-- Some OS toolchains generate obsolete LR/SC instructions with now
-  illegal combinations of `.aq` and `.rl` flags.  You can work-around
-  this by changing `riscv_mem.sail` to accept these flags.
+Booting OS images
+-----------------
 
-- One needs to manually ensure that the DTB used for the C model
-  accurately describes the physical memory map implemented in the C
-  platform.  This will not be needed once the C model can generate its
-  own DTB.
+For booting operating system images, see the information under the
+[os-boot/](os-boot/) subdirectory.

+Booting OS images
+=================
+
+The Sail model implements a very simple platform based on the one
+implemented by the Spike reference simulator.  It implements a console
+output port similar to Spike's HTIF (host-target interface) mechanism,
+and an interrupt controller based on Spike's CLINT (core-local
+interrupt controller).  Console input is not currently supported.
+
+Booting Linux with the C backend
+--------------------------------
+
+The C model needs an ELF-version of the BBL (Berkeley-Boot-Loader)
+that contains the Linux kernel as an embedded payload.  It also needs
+a DTB (device-tree blob) file describing the platform (say in the file
+`spike.dtb`).  Once those are available (see below for suggestions),
+the model should be run as:
+
+```
+$ ./c_emulator/riscv_sim_<arch> -t console.log -b spike.dtb bbl > execution-trace.log 2>&1 &
+$ tail -f console.log
+```
+The `console.log` file contains the console boot messages. For maximum
+performance and benchmarking a model without any execution tracing is
+available on the optimize branch (`git checkout optimize`) of this
+repository. This currently requires the latest Sail built from source.
+
+Booting Linux with the OCaml backend
+------------------------------------
+
+The OCaml model only needs the ELF-version of the BBL, since it can generate its
+own DTB.
+```
+$ ./ocaml_emulator/riscv_ocaml_sim_<arch> bbl > execution-trace.log 2> console.log
+```
+
+Caveats for OS boot
+-------------------
+
+- Some OS toolchains generate obsolete LR/SC instructions with now
+  illegal combinations of `.aq` and `.rl` flags.  You can work-around
+  this by changing `riscv_mem.sail` to accept these flags.
+
+- One needs to manually ensure that the DTB used for the C model
+  accurately describes the physical memory map implemented in the C
+  platform.  This will not be needed once the C model can generate its
+  own DTB.
+
+Sample OS images
+----------------
+
+This directory contains some sample OS images and support files built
+for the basic platform implemented by the model.  They were built with
+toolchains that emitted illegal instructions, and require the model to
+be patched to boot them:
+
+```
+patch -p1 < os-boot/os-boot-patch.diff
+```
+
+The device-tree for the 64-bit Sail model is described in `rv64-64mb.dts`.  This file
+can be generated using:
+```
+./ocaml_emulator/riscv_ocaml_sim_RV64 -dump-dts > os-boot/rv64-64mb.dts
+```
+
+The device-tree binary for OS boots can be compiled from that source file:
+```
+dtc < os-boot/rv64-64mb.dts > os-boot/rv64-64mb.dtb
+```
+
+The 64-bit Linux image can then be booted as:
+```
+./c_emulator/riscv_sim_RV64 -b os-boot/rv64-64mb.dtb -t /tmp/console.log os-boot/linux-rv64-64mb.bbl > >(gzip -c - > /tmp/exec-trace.log.gz) 2>&1
+tail -f /tmp/console.log
+```
+
+The 64-bit FreeBSD image requires hardware PTE update support (`-d`):
+```
+./c_emulator/riscv_sim_RV64 -d -b os-boot/rv64-64mb.dtb -t /tmp/console.log os-boot/freebsd-rv64.bbl > >(gzip -c - > /tmp/exec-trace.log.gz) 2>&1
+```
+
+The 64-bit seL4 image runs its test-suite and requires more memory (`-z`):
+```
+dtc < os-boot/rv64-2gb.dts > os-boot/rv64-2gb.dtb
+./c_emulator/riscv_sim_RV64 -z 2048 -b os-boot/rv64-2gb.dtb -t /tmp/console.log os-boot/sel4-rv64.bbl > >(gzip -c - > /tmp/exec-trace.log.gz) 2>&1
+```
+
+Note that the consistency of the `-z` argument and the contents of the
+DTB have to be ensured manually for now.
