Enhancement request - regparm

[Patrick Pelissier]

Hi,

 It isn't really a bug, and i don't know if it has been reported yet (I 
suppose so, but I haven't found it exactly in the archives).

 As you know, glibc uses the stack to pass the arguments to a function, 
by default. If you compile a program which used glibc with -mregparm=3, 
it crashes because the ABI are incompatible.

 So my question is: Why don't you add
   __attribute__ ((__regparm__(0)))
 to all the glibc functions in the header files to prevent such a problem ?

 Are there any drawback problems ?

 Sincerely,
  Patrick Pelissier
