Revision 138733 has:

  if (flag_dwarf2_cfi_asm && dwarf2out_do_frame ()) 
    cpp_define (pfile, "__GCC_HAVE_DWARF2_CFI_ASM");

It doesn't work with PCH:

/export/gnu/import/svn/gcc-test/src/gcc/testsuite/gcc.dg/pch/valid-1b.c:3:
warning: ./valid-1b.h.gch: not used because `__GCC_HAVE_DWARF2_CFI_ASM' not
defined
/export/gnu/import/svn/gcc-test/src/gcc/testsuite/gcc.dg/pch/valid-1b.c:3:

/export/gnu/import/svn/gcc-test/src/gcc/testsuite/gcc.dg/pch/valid-1b.c:3:
error: one or more PCH files were found, but they were invalid
