dbxout.c (FORCE_TEXT): Switch to current_function_decl, not text_section.
2002-09-26 David Edelsohn <edelsohn@gnu.org>
* dbxout.c (FORCE_TEXT): Switch to current_function_decl, not
text_section.
* xcoffout.h (DBX_STATIC_BLOCK_START): Remove explicit change to
text section.
* config/rs6000/rs6000.c (rs6000_override_options): Allow
function-sections and data-sections functionality on AIX.

The IBM rs6000/AIX assembler has a bug that causes bss block debug - info to be occasionally lost.

The `b:S-1' must be between the `.bs' and `.es'. - We can apparently work around the problem by forcing the text section - (even if we are already in the text section) immediately before outputting - the `.bs'.
