Qualifiers
+Every function must declare its linkage explicitly:
+ +
+fn //globally visible, default linkage
+fn_static //translation unit-local only
+fn_inline //inline-only, no symbol emitted
+fn_asm //raw assembly function, globally visible
+fn_static_asm //raw assembly function, TU-local only
+fn_inline_asm //inline-only asm, no symbol emitted
+fn_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.
+fn u32 add(u32 a, u32 b) {
+ return (a + b);
+}
+
+fn_inline u32 max(u32 a, u32 b) {
+ return ((a > b) ? a : b);
+}
+
+fn exit() {
+ // equivalent to fn void exit()
+}
+Assembly
+Write raw x86_64 assembly using fn_asm or fn_static_asm. Symbol, section, and global declaration are implicit.(placeholder)
+fn_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
+}
