gcc should never inline functions which have a 'section' attribute set
on them.
If the section is placed at a specific location in memory via a linker
script, then the function will not be placed into its correct address,
and the resultant executable is incorrect.
gcc 4.1.1 will inline static function at -O1 and -O2, but not -O0 and
-O3; this can be seen by compiling the attached test program at
various optimization levels.
static int __attribute__((section(".special_section")))
special_function_0(void)
{
return 0;
}
int __attribute__((section(".special_section")))
special_function_1(void)
{
return 0;
}
int main(void)
{
special_function_0();
special_function_1();
return 0;
}
