"What is better "int 0x80" or "syscall" [or "sysenter" or VDSO] in 32-bit code on Linux?" https://stackoverflow.com/questions/12806584/what-is-better-... links to https://stackoverflow.com/questions/12776340/system-calls-im... which links to the vDSO Wikipedia article, which explains that vDSO supports ASLR and is more portable than `int 80` (which is the old 32bit way to syscall)

WASI: https://en.wikipedia.org/wiki/WebAssembly :
> WebAssembly System Interface (WASI) is a simple interface (ABI and API) designed by Mozilla intended to be portable to any platform.[84] It provides POSIX-like features like file I/O constrained by capability-based security.[85][86] There are also a few other proposed ABI/APIs.[87][88]
