Could the size regression be related to #103837 @tannergooding ? The full range is 5795e8c...4a1a076

This is a significant regression (~0.6MB on the .app size). Fyi: @fanyang-mono @vitek-karas

Could the size regression be related to #103837 @tannergooding ?

Potentially. There were a significant number of APIs added and they have quite a lot of logic behind them. They also use generics to reduce the amount of code needing to be maintained, without the use of generics every API added would've need to have the same logic manually duplicated at least 7x. In some cases they would need to be duplicated up to a further 10x beyond that. -- The 7 is for each of the vector types (Vector64/128/256/512<T>, Vector<T>, and Vector2/3/4) and the 10 is for each of the supported primitive types (int8/16/32/64, uint8/16/32/64, float, and double). That's not including the dispatch logic for nint/nuint and its worth noting that not all APIs need all 10 types, some only need float/double; but it's still a lot of maintainability savings.

This is also without trimming, correct?

[radekdoulik]

I see it on webassembly too, with trimming enabled. cc @lewing

[tannergooding]

That's a bit unexpected to see it with trimming. These are essentially all net new APIs that shouldn't be getting used anywhere and so shouldn't be getting kept around in the trimmed assembly

[matouskozak]

That's a bit unexpected to see it with trimming. These are essentially all net new APIs that shouldn't be getting used anywhere and so shouldn't be getting kept around in the trimmed assembly

I believe Mono is currently unable to trim out these APIs because it's not able to distinguish if only a some of the class APIs get used and the rest doesn't. Consequently, it it generates a code for every method of the class

I'm closing in favor of #105701, feel free to re-open if you think this issue requires a separate attention.
