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.
I have way too often accidentally edited the generated file.

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.

Skgland 248b05c992 use as_bytes().to_vec() instead of bytes().collect()
