was using exit, since raise is not implemented. This was ambiguous as all programs exit.
Using :died as special kernel code and bending it, and reporting it in interpreter.
Now we are using a statically linked list of messages. This will not work with procs, but that can be solved then.
Previous (wrong) thinking was that because of procs messages have to be allocated for every call. This was too slow, and not neccessary
Just like the args, locals are now inlined into the Message.
Message is off course bigger, but as they are created at compile time, that hardly matters
Some programs did get somewhat smaller, especially with both changes, but not super much
After having over 600 failing tests at one point, this does feel good.
Even better, most of the risc/interpreter tests where i didn't change anything came gree without changing the tests. ie we have binary compatibility.
Since Builtin generates risc, just like mom instructions, it was a design mistake to put builtin into risc in the first place. Now that borders are coming more into focus, it make much more sense to have the builtin in mom.
In fact the instructions should be moved out and a seperate invocation mechanism used , so functions can be parsed, not generated (wip)
last orrurences in syscalls replaced, 2 variants
- exit does not actually need the int
- all else, preallocate the int beforehand and in syscall assume the reg name (integer_tmp)
test missing
Wherever space was loaded to get to the next_message
we now load the Message factory.
Otherwise much the same, only the attribute is next_object, not next_message
The binary is growing with 1k objects per factory, so i had to fix (hack) arm to handle bigger constants
close#14
now a variable has to be created before being used
thus it is save to develop contracts where a certain name
must exist in the scope
Maybe the syntax starts getting a bit weird, but at least the ! is a common symbol in ruby
these types are only needed to debug and can be gotten from the method (also in the mesage)
just saving the 6 instructions for every call
This was made possible through previous commits on fake_memory access
