i'm convinced making simd work well is akin to magic

Mis vbyte a variable-length integer
Pyep
Moh okay
Aooh
Mthat explains a lot
Mlooked it up and just got bitcoin stuff
Mwhat is it.. for
Moh, storing packed arrays of ints and operating on them
Lin zig the compiler just gives you some nice vector types and functions and does all the hard work for you :^)
Lyou can do
@Vector(8, u32) to get a type and any operations you do on said type gets broken down by the compiler into the smallest amount of SIMD instructions it can
Trust has the same, and it's hit or miss
Lyeah im sure for optimal perf its not perfect, but in general it gives good results and is a million times easier
Lyou can always inline asm the raw instructions
Tban the asm
Li think the stdlib has some of them already done for you for x86 and arm
Ayeah
Athats cool
Lits basically free SIMD for a lot of stuff, since
@Vector is just nice in general for stuff like color typesAc-colour simd types???
Awhat are you doing with colours that requires simd
Lmultiplying
Tmeh, they can't put everything behind a do-it-all magic helper
Lalpha
Laddition
AOHFUCKIREGRETALTTABBINGOUTOFOSUNOWHELP
Lyeah not everything is behind the magic helper, but thats what
std.simd and inline asm is forL@Vector is good enough for most cases thoughTinline asm more like death, straight up
Mimage operations
Lits not that bad in Zig
L
Tthat is literally just pain
Afun fact: rust supports inline asm
Afor some reason
Lsome reason?
Lit makes sense
La systems language has to have some form of inline asm
Llike people push rust as an OSdev lang
Lit wouldnt be a very good one without inline asm
Atrue
Kimo that one syntax for asm sucks but iirc having to use it is an upstream issue in zig
Lyup
LLLVM's intel syntax support is fucked
Pman i love rust macros
Lwhat the fuck is this i have never seen this before
Lthats weird
Llike ig it makes sense
Lbut WEIRD
Mhelps resharper detect mistakes by establishing when a method is guaranteed to return null or not null if the input is null or not null
Malso exists in intellij
