Arm-none-eabi function that never used

[deadlyboy]

hi every body

i my code where ever i defined variable which i never used , at compile time the compiler eliminate it from compiled code .

so how about unused functions . are they compile ?? i google it and i found it depends on compile but i don't know Arm-none-eabi eliminates that function or not

thanks in advance

The function is compiled by the compiler, then the linker "garbage collector" removes unused functions from the final code, same for variables.
