Torsten e8111c259b fix last tests that required faked returns 2020-03-28 19:46:07 +02:00
Torsten a3effe29f6 adding integer compare tests and fixing returns 
true, false and nll were not handled correctly as returns
returns assume int, and reduce. The solution (hack?) is to add fake numbers into true,false and nil that get returned from from the arm syscall
(and it works!, which means i can fix other tests now)
 2020-03-28 18:41:59 +02:00
Torsten 8dfcc0f5de add decent method to get the programs return to interpreter 
only had such methods in tests, but they really belong in code
also adding fake values to true ,false and nil
 2020-03-28 18:39:49 +02:00
Torsten 4bae5c418b fix register use in putstring 
was off by one, the syscall is write 
and the first arg is file_descriptor
ie 1 == stdout
 2020-03-26 11:24:56 +02:00
Torsten bc558d1f0d do not copy name of method 
so that the resolve can compare name identity
which is what is does, not equality
this (and some other bug) is crashing arm currently
 2020-03-25 12:43:57 +02:00
Torsten 90935bfbbc risc is GREEN 
totally, man.
Small fix in method missing fixed last block tests
(why, i do not know)
 2020-03-22 15:58:19 +02:00
Torsten ddd1f4e296 fix interpreter syscall and rename return reg 
returned int for puts was same name as implicit return  int
 2020-03-22 14:31:43 +02:00
Torsten be684c0c43 move message to stack_pointer 
changing a bunch of register names
some of which get names now
 2020-03-22 14:31:43 +02:00
Torsten a93a3c8af5 fix most interpreter tests 2020-03-22 14:31:43 +02:00
Torsten 06ade75593 Fix non ssa issue 
register instances were being shared across instructions
causing the setting to have side-effects
Fixed this by copying the register on write
(fixing the symptom rather than the cause, i'll make an issue)
 2020-03-22 14:31:43 +02:00
Torsten d2e7c647d0 setting registers in the allocator 
unfortunately the reg instances are spread across instructions
this causes problems when setting them
 2020-03-22 14:31:43 +02:00
Torsten c890e8402b change in register_names protocol 
move to returning the attribute names
getting and setting can then be automated in the base class
 2020-03-22 14:31:43 +02:00
Torsten 0137056b89 change platform to return register names 
not just the number of them
also adds protocol to map registers
(like message to r0 , or syscalls)
 2020-03-22 14:31:43 +02:00
Torsten f13e6dcf57 fix releasing in allocator 
fell into hash new trap, which reuses the object you give it. not good for mutable objects like the array.
also previous logic was broken in terms of machine vs ssa names
 2020-03-22 14:31:43 +02:00
Torsten 3f131a4018 start with register assigning 
have to find a way to set them next
 2020-03-22 14:31:43 +02:00
Torsten 4f290ee246 basic liveliness for allocator 2020-03-22 14:31:43 +02:00
Torsten d0b734c57c adding register_names to instruction protocol 2020-03-22 14:31:43 +02:00
Torsten 8df1b8126f add register names to allocator 
make platform instantiate it
basic plumbing
 2020-03-22 14:31:43 +02:00
Torsten 500df01425 rename allocator to standard_allocator 
planning to have platform dish it out
 2020-03-22 14:31:43 +02:00
Torsten 2e109a16dc starting on risc allocation 
inserting allocator stage in method translation
 2020-03-22 14:31:43 +02:00
Torsten e4a79aac50 reset flags in interpreter 
fix at least part of the problem why comparisons dont work
 2020-03-22 14:31:43 +02:00
Torsten 3ce6ed5263 fix putstring and puts 
using syscall regs
 2020-03-22 14:31:43 +02:00
Torsten 17a7f29b0c define and use syscall_XX registers 
rather than use hardcoded r0 etc use syscall_X
change the syscalls and interpreter to use them
later use platform to map from syscall_X to actually used register (like r0 in arm)
 2020-03-22 14:31:43 +02:00
Torsten 7232c28ecd operator also fell into ssa trap 
relying on register identity
in fact the whole operator concept was geared towards this, using 2 regs instead of one to avoid the whole issue
better now
 2020-03-22 14:31:43 +02:00
Torsten 5b0c1195e4 Fix interpreter and resolve method 
Interpreter was not handling ssa correctly (ie overwriting)
Resolve was assuming wrong registers (also non ssa)
return value still broken
 2020-03-22 14:31:43 +02:00
Torsten 4db71c1c03 fix all uses of operators now they are ssa 2020-03-22 14:31:43 +02:00
Torsten 0cde7c1d0a debugging to find operator not being ssa 2020-03-22 14:31:43 +02:00
Torsten 61fc8a3991 make operator_instruction single ass 
create result register automatically
usually not used, but register allocation will sort that
 2020-03-22 14:31:43 +02:00
Torsten 1378745907 first interpreter tests 2020-03-22 14:31:43 +02:00
Torsten c16ed5ab3a fix interpreter 
by currently not checking for old register pattern
feels like wip, but passes (all but one)
 2020-03-22 14:31:43 +02:00
Torsten f2250bc206 fix resolve and introduce method to chop strings to max 
strings are 20 bytes. I want to implement the extension idea, just not now
 2020-03-22 14:31:43 +02:00
Torsten 2656bfacb2 create a reduce_int on RegisterSlot 
that just passes through to RegisterValue by calling to_reg
 2020-03-22 14:31:43 +02:00
Torsten 8abcaa330b fix allocate in builder 
which accessed unknown types.
also moved assert_allocate to support
 2020-03-22 14:31:43 +02:00
Torsten c9fedec230 add a way to bend the type for register_value 
specifically for factories, where we know the type of next_object even it is not specified
 2020-03-22 14:31:43 +02:00
Torsten 6267bf3ad0 fix slot_to_reg to allow register indexes 
we mostly use pre-calculated indexes, ie integers
but registers are allowed (in arm/risc), so we try to check the registers type at least is right.
The return is really a machine word, but we call it Object (yes, more work that way)
 2020-03-22 14:31:43 +02:00
Torsten fb4fa598f2 fix get_internal_byte 
improved operators and tests
some logic errors still
 2020-03-22 14:31:43 +02:00
Torsten 12fe0b9a10 add constants automatically 2020-03-22 14:31:43 +02:00
Torsten 22d513d895 fix div4 and tests 
also bug in reduce_int, compiler not carried through
 2020-03-22 14:31:43 +02:00
Torsten eed9ba082f Fix div10 and test 
fix and use load_data (similar to load_constant)
and integrate into load_object when appropriate (ie for integers)
 2020-03-22 14:31:43 +02:00
Torsten bd02f69824 reduce_int was overwriting register 
No more. But the type question is open, ie what type does the resulting register have
 2020-03-22 14:31:43 +02:00
Torsten 53eb28fff4 load constant to create register names with class 
Just the id_ did give no clue to the contents, just took care of the uniqueness.
Better for debugging
 2020-03-22 14:31:43 +02:00
Torsten 3ec5557ddb fix builder logic error 
and tests
 2020-03-22 14:31:43 +02:00
Torsten 9c5d17a3bb Fix div10 without method_missing 
but reanimate infer_type to auto create the needed regsiters
also some helpers
 2020-03-22 14:31:43 +02:00
Torsten 9a5e0f15cd reannimate infer_type 
now with a _purpose_
 2020-03-22 14:31:43 +02:00
Torsten 3688c967d3 Fix comparison macro 
which leaves a definite need for instruction level testing
 2020-03-22 14:31:43 +02:00
Torsten fd43fc9e5c finally fixes the builder 2020-03-22 14:31:43 +02:00
Torsten db5a59f735 Unify instruction namings also dirs 
Was getting confused myself, where it was instruction or instructions, when if the base class was inside or out of dir.
Now dirs are plural, and base class is inside.
 2020-03-22 14:31:43 +02:00
Torsten f3d299208e fix message_setup with new builder 2020-03-22 14:31:43 +02:00
Torsten ece1e8c87b fix some more of builder 
but still not all. removed some and fixed the register allocation in allocate_int
 2020-03-22 14:31:43 +02:00
Torsten ff49ff50c0 Convert SimpleCall to new regs 
Also fix bug in RegsiterValue/Slot with chain, where logic was dodgy and compiler not set
 2020-03-22 14:31:43 +02:00
