#3874 Local variables that have their address taken in inline function definitions end up in asm

[Philipp Klaus Krause]

When an inline function definition contains a static local variable that has its address taken, space is allocated for this variable, even if no code is emitted for the inline function. I.e. this file

extern void *m (void *p);

inline void l(void) {static unsigned char v; m (&v);}

Compiles into:

    .area DSEG    (DATA)
_l_v_10000_3:
    .ds 1

For ports, where --stack-auto is not the default, this also affects variables not declared static. This is a serious issue for those ports, as just including a header with some inline functions can easily result in running out of RAM.

There is a partial fix in [r15645], that works for the example above (and the rotation functions from stdbit.h), but is not enough for some others (in particular the endian-aware load functions from stdbit.h).

Fixed in [r15646].
