SDL_MMX_INTRINSICS(3)

💖 SDL_MMX_INTRINSICS 💖

okay bestie so this is a page from the SDL3 FUNCTIONS manual, and it's literally about one lil' macro. yes, one. and she's iconic for it. 💅

---

✨ NAME ✨

SDL_MMX_INTRINSICS — defined if (and only if) your compiler supports Intel MMX intrinsics. no cap, that's the whole job. 🎀

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_intrin.h>

#define SDL_MMX_INTRINSICS 1

like... that's it. that's the vibe. 🦋

---

✨ DESCRIPTION ✨

so here's the tea 🍓: if this macro is defined, then SDL will have already included <mmintrin.h> for you. you don't gotta do it yourself, she already handled it. main character energy fr fr. 👑

translation: seeing SDL_MMX_INTRINSICS defined = the compiler said "yes, I speak MMX" and SDL went ahead and pulled in the header. the way that this is just handled... obsessed. ✨

---

✨ AVAILABILITY ✨

this macro has been available since SDL 3.2.0. so if you're on anything older, sorry babe, she wasn't born yet. 😭

---

✨ SEE ALSO ✨

• SDL_SSE_INTRINSICS(3) — her sister, same energy, different SIMD. go read that one next bestie 🫶

and that's the whole page!! short, sweet, slay. this was from the Simple Directmedia Layer manual, version SDL 3.4.18. mwah, love u, go write some SIMD code 💖✨🎀🦋
