[Bug c++/99508] New: Asm labels declared inside a function are ignored

Bug ID: 99508
   Summary: Asm labels declared inside a function are ignored
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: frank.mehnert at googlemail dot com
  Target Milestone: ---

This is apparently a gcc-11 regression. Following example:

#include 
void foo()
{
  void bar() asm ("bar_assembler");
  extern unsigned buzz asm("buzz_assembler");
  bar();
  printf("%d\n", buzz);
}

Compile this C++ source code with -c and look at the generated symbols with
'objdump -tC'. 

g++-10:
 *UND*   bar_assembler
 *UND*   buzz_assembler
 *UND*   printf

g++-11: (Debian experimental 20210306):
 *UND*   bar()
 *UND*   buzz
 *UND*   printf

g++11 produces the same result as g++10 if 'bar' and 'buzz' are declared
outside foo().
