Hi Mike,
Thanks very much for the detailed review. Attached is a second
attempt at contributing this work. New in this edition are:
* A basic pass/fail testsuite based upon similar code in the moxie
directory. I am planning to expand this to a proper, full testsuite
later on.
* The gdb-if.c file has been renamed to interp.c.
* The files now have an appropriate FSF copyright notice.
* The enum values in sim-aarch64.h are now in uppercase.
* The configure.ac file is now a clone of the one in sim/arm.
* The sources now compile in ISO C90 mode.
* Extraneous whitespace has been removed.
* The standard uintX_t types are used throughout.
* Most global state is now held in the SIM_DESC structure.
* // comments have been replaced with /* ... */
* Prints to stderr have been replaced by calls to sim_io_eprintf
* Register numbers are stored in an enum.
* Updated Makefile.in.
* The tracing code has been replaced with the sim/common tracing
functions.
* The sim common core memory functions are now used to read and write
memory.
I hope that this rewrite meets your approval.
OK to apply ?
Cheers
Nick
