You need to look at non-x86 architectures. It was common years ago on MIPS. * https://jdebp.uk/FGA/function-perilogues.html#StandardMIPS https://jdebp.uk/FGA/

It was common years ago on MIPS. * https://jdebp.uk/FGA/function-perilogues.html#StandardMIPS https://jdebp.uk/FGA/function-perilogues.html#StandardMIPS I wrote up the x86 equivalent of doing just two read-modify-write operations on the stack pointer over 16 years ago. * https://jdebp.uk/FGA/function-perilogues.html#Standardx86 https://jdebp.uk/FGA/function-perilogues.html#Standardx86
