[Bug target/17982] New: [4.0 regression] asm declaration ignored due to conflict with previous rename

[schwab at suse dot de]

When an identifier has been used in an inline declaration subsequent renames 
of it are ignored.  That used to work with gcc 3.4 and still works on i386 and 
ppc at least.  This breaks building glibc. 
 
$ cat asm.c 
extern int foo (void); 
extern inline int 
bar (void) 
{ 
  return foo (); 
} 
extern __typeof (foo) foo __asm__ ("mumble"); 
int foobar (void) 
{ 
  return bar (); 
} 
$ gcc-4.0 -O -S asm.c 
asm.c:7: warning: asm declaration ignored due to conflict with previous rename 
$ grep mumble asm.s 
$ grep foo asm.s 
	.global foobar# 
	.proc foobar# 
foobar: 
	br.call.sptk.many b0 = foo# 
	.endp foobar#
