PR 18199 * dbxout.c (dbxout_begin_complex_stabs_noforcetext): New function. (DBX_FINISH_STABS): Add (unused by default) SYM parameter. (dbxout_finish_complex_stabs): Update to match. (dbxout_symbol_location): Call emit_pending_bincls_if_required and FORCE_TEXT before DBX_STATIC_BLOCK_START. Use dbxout_begin_complex_stabs_noforcetext. * xcoffout.h (DBX_FINISH_STABS): Restore special case for N_GSYM, using new SYM parameter. Correct logic for special cases for N_FUN. From-SVN: r89781
