For machines that must pop arguments after a function call, the > compiler normally lets arguments accumulate on the stack for several > function calls and pops them all at once. > > Disabled at levels -O, -O2, -O3, -Os. > > https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Optimize-Options Confirming that this is still confusing though.
