https://github.com/D-Programming-GDC/GDC/commit/79ebb4c0012485528cbf900b8bc8280423a872ff

Now puts out:

D main ()
{
  int D.2453;
  struct  D.2452;
  int test.test9_1_e.0;
  int test.test9_1_e.0_1;
  int _2;
/* ... */
}


When fixing this, I found that d_comdat_group was calling DECL_ASSEMBLER_NAME
before one had been set for var decls, oops.  That is not good if the DECL_NAME
has unfriendly symbols in it (eg: "quotes").

https://github.com/D-Programming-GDC/GDC/commit/64b4aa77a5d1e7254f783f9b835df216d85a3f0b

However, the code logic in -fdump-tree-optimized-asmname is still not right:

{
  <bb 2>:
  test_эльфийские_письмена_9 = 42;
  test.test9_1_e.0_1 = test_эльфийские_письмена_9;
  if (test.test9_1_e.0_1 == 42)
}


So finally:

https://github.com/D-Programming-GDC/GDC/commit/942298f595e95cc60d75fa111645498420f6aa2e

{
  <bb 2>:
  *test_эльфийские_письмена_9 = 42;
  test.test9_1_e.0_1 = *test_эльфийские_письмена_9;
  if (test.test9_1_e.0_1 == 42)
}


Fixed!
