Explanations

• Target platform

• Syscalls

• Creating small static binaries, ELF header hacks (notes on doing the same, on ARM)
• Process creation
• Dynamic linking

• C runtime

• dnload: interesting read on all things sizecoding on mostly FreeBSD, but is applicable to Linux as well. Mostly correct and up-to-date, minus our smol hacks.

• vondehi
• smol: see dynamic linking
