-fno-inline-functions
Disabling the inlining of functions can help to improve the debug experience.
The compiler attempts to automatically inline functions at optimization levels
-O2
and -O3
. When these levels are used with -fno-inline-functions
,
automatic inlining is disabled.
When optimization levels -O0
and -O1
are used with -fno-inline-functions
, no automatic
inlining is attempted, and only functions that are tagged with
__attribute__((always_inline))
are inlined.
