builtins.h(3avr)

💖 NAME 💖

okay so it's builtins.h, bestie — and this whole page is the 3avr manual entry for it. it's the header that keeps a lil' collection of AVR compiler builtins, and we are going through every single one, no skips, no crumbs left behind. periodt. ✨

🎀 SYNOPSIS 🎀

🍓 Macros

literally one macro in this entire house, and here she is in all her glory:

• __HAS_DELAY_CYCLES — defined as 1. that's the whole thing. iconic, unbothered, thriving 💅

🦋 Functions

and now the builtin squad, signatures exactly as they come, no notes, no edits, i would never:

• void __builtin_avr_sei (void) — takes nothing, gives nothing back. void in, void out, zero drama 🫶
• void __builtin_avr_cli (void) — also no arguments and no return value. she simply exists 💖
• void __builtin_avr_sleep (void) — no args, no return, just vibes 😴
• void __builtin_avr_wdr (void) — again: nothing in, nothing out 🌸
• uint8_t __builtin_avr_swap (uint8_t __b) — hands you back a uint8_t, and it wants a uint8_t __b to work with 🧚
• uint16_t __builtin_avr_fmul (uint8_t __a, uint8_t __b) — returns a uint16_t and asks for two uint8_ts, __a and __b 🔥
• int16_t __builtin_avr_fmuls (int8_t __a, int8_t __b) — returns an int16_t, takes two int8_ts, __a and __b ⭐
• int16_t __builtin_avr_fmulsu (int8_t __a, uint8_t __b) — returns an int16_t, takes an int8_t __a and a uint8_t __b, yes the types are different, read it again bestie 👀

fr fr, every one of these is listed with its exact argument types and return type above — do not come for me saying i merged two of them. i did not. 🙈

👑 Author 👑

no human author on this one, bestie — it was Generated automatically by Doxygen for AVR-LibC from the source code. the robot wrote it and honestly? it ate 🔥

and that's the whole page, we did it 💜 this cutie reached you courtesy of AVR-LibC, Version 2.2.1 — mwah, go build something, main character 🎀
