Hello Richard

Thanks for doing this.
Unfortunately the changes appear to force all local functions to be
called as indirect refs.
eg:

With your patch, this:

static int bar (void) __attribute__((noinline)) ;
static int bar () {return 0;}
int foo () { return bar( );} 
 
foo gets compiled as 

	pushl	%ebp
	movl	%esp, %ebp
	movl	$_bar, %eax
	call	*%eax
	popl	%ebp
	ret

rather than (without your patch) as:

_foo:
	pushl	%ebp
	movl	%esp, %ebp
	call	_bar
	popl	%ebp
	ret

This causes failure of libgcc build in unwind-dw2.c where, with
optimization,  we get invalid assembly code like this:
...
	call	*$_read_uleb128
