Skgland af54fb2aba optimize put_back_char 
Always encode the char directly into the buffer.
Only shift the buffer content if there isn't enough room in the front.

Skgland eac7ff680c fix ArenaPtr payload offset logic 
the old logic would be incorrect if the payload has higher alignment than the ArenaHeader i.e. when there is padding between the ArenaHeader and the Payload
 2026-04-25 18:12:32 +02:00
Skgland b4db85c8c3 don't erase ptr type early when construction a Cons HeapCellValue 
rather than passing an address as usize pass the ArenaHeader pointer
similarly don't return a u8 ptr but use a ArenaHeader pointer instead

Don't convert the pointer to a ConsPtr by going through native endian
bytes in between.
We are exploiting the fact that the 3 least significant bytes are zero
for pointer to types of alignment 8 and we expect these to line up with
the f, m, and tag field at the end of the ConsPtr struct, but using
native endiannes for this would only work on big endian systems.

Skgland 6765921666 fix unused import warning on windows 2026-04-25 16:19:58 +02:00
Skgland ff293a56e6 fix large enum variant size difference warning of PermVarAllocation 
by wrapping BranchNumber in an Arc.
PermVarAllocation::Done had size 208 and is now down to 32.
A Box rather than an Arc would be smaller, but it looks like BranchNumber/BranchDesignator are clones a bunch so I expect it to be beneficial to reduce allocations both of the Box itself as well as its content.

Skgland 3c9c7ade8d use checked_add to prevent silent overflow 2026-03-27 22:00:54 +01:00
Skgland 5fc21241d6 hint to the compiler/branch-predictor that 
we expect p to be in bound

if we are suffiently certain that p can never be oob
unsafe get_unchecked could be used to
eliminate bounds checking all together
which should improve performance further.

Skgland 153f04b72a adjust interrupt handling 
we used to spend ~5.8% of the time on getting the next value of the 0..INSTRUCTIONS_PER_INTERRUPT_POLL iterator

increment on Wrapping<u8> now only takes ~0.58 of the time
 2026-03-21 14:20:11 +01:00
Skgland 8aab887388 switch from Integer to u128 
- u128 is only 16 bytes instead of 24
- incrementing u128 does not involve heap allocations
- u128 should be sufficent
 it would take more than 2 sextilion years to overflow if we would be incrementing it every tick at 5GHz
   i.e. 2^128-1 / 5 GHz / 60 / 60 / 24 / 356 > 2 sextilion

before this ~3.2% of the execution time of the program in https://github.com/mthom/scryer-prolog/issues/3265#issuecomment-4103176469 was spend in the increment_call_count function, after this change it's down to 0.3%

Skgland 73c26bed2a extaract the static part of the instructions template directly into the instructions module 
This way goto source doesn't end up in a generated file for those parts and they can be edited directly.

Skgland 797a8f8611 fix function_casts_as_integer warning 
Comparing addresses of function pointers is brittle.

Functions may be duplicated resulting in function pointers to the same function to compare !=.
Functions may be merged/de-duplicated resulting in function pointers to different function to compare ==.

The later shouldn't be relevant here as the function differ in behavior, but mentioning it for completeness.

Skgland 6ec8c9064f fix pstr_iter_tests test 2025-11-20 23:08:46 +01:00
Skgland d4f2f7ba2b remove RESOURCE_ERROR_OFFSET_INIT 
With it when using multiple Machine in one process only the first would store the pre-allocated error.
Instead Heap.resource_err_loc is now Option<NonZero<usize>> instead of usize using None for uninitialized.
The cell at index 0 should alredy be used by a runtime reserved interstitial cell that is allocated prior. So requiring the offset to be non zero should be fine.
