Qualifiers
-Every function must declare its linkage explicitly:
- -
- //globally visible, default linkage
-static //translation unit-local only
-inline //inline-only, no symbol emitted
-asm //raw assembly function, globally visible
-static_asm //raw assembly function, TU-local only
-inline_asm //inline-only asm, no symbol emitted
-async //for fiber (coroutine) ??
-Syntax
-All functions must explicitly declare their return type. The only exception is void, which may be omitted for brevity when no return value is intended.
-u32 add(u32 a, u32 b) {
- return (a + b);
-}
-
-inline u32 max(u32 a, u32 b) {
- return ((a > b) ? a : b);
-}
-
-exit() {
- // equivalent to void exit()
-}
-Assembly
-Write raw x86_64 assembly using fn_asm or fn_static_asm. Symbol, section, and global declaration are implicit.(placeholder)
-asm void* memset(void* dst, u8 value, u64 size) {
- test rdx, rdx
- je .done
-
- mov rax, rsi
- mov rdi, rdi
- mov rcx, rdx
-
- rep stosb
-
-.done:
- mov rax, rdi
- ret
