And indeed, for x86_64 we have

[EMAIL PROTECTED]:/abuild/rguenther/trunk-g/gcc> ./xgcc -B. -Os
-fdump-ipa-inline t.i -c
[EMAIL PROTECTED]:/abuild/rguenther/trunk-g/gcc> size t.o 
   text    data     bss     dec     hex filename
     94       0       0      94      5e t.o
[EMAIL PROTECTED]:/abuild/rguenther/trunk-g/gcc> ./xgcc -B. -Os
-fdump-ipa-inline t.i -c -fno-inline
[EMAIL PROTECTED]:/abuild/rguenther/trunk-g/gcc> size t.o 
   text    data     bss     dec     hex filename
    123       0       0     123      7b t.o

so with inlining the function twice text size is smaller than without inlining.
