WebThroughout my journey of attempting to make the most performant bytecode interpreter (challenge was to use NO JIT compilation), I have learned that using uintptr_t was overall superior than using void* for the same operations.. A few of the reasons are because of the strict aliasing rule in C and the use of scope-limited, restricted pointers, and optimization … WebFrom: Warner Losh To: [email protected] Cc: [email protected], [email protected], Kyle Evans , Ryo ONODERA , Brad Smith , Warner Losh , [email protected], Stacey Son , Richard …
